Service Bulletin SB 19-09-09 Published - Inspect RV-10 gear leg mount lug
Van's Aircraft has published a new Service Bulletin for the RV-10, SB
19-09-09. This bulletin directs RV-10 owners to inspect the inboard
attachment lugs on the RV-10 nose gear leg for potential cracks at a
specific location. If no cracks are found, the gear leg is serviceable and
you may continue to fly the airplane and re-inspect each year at the annual
condition inspection. Replacement is not necessary in that case.
If a crack is found, owners are directed to order a kit that contains an
updated RV-10 nose gear leg and associated hardware. This is described in
the service bulletin document.
Europe Formation Clinic 2019 ...lucaperazzolli
Finally, I found the time to edit a bunch of videos taken during our FFI Italian
Meeting. Me and Franz hosted the RV group at our airport (LITD) in September
2019 with the support and energy of Tobias Treichel (he had been in West Coast
Formation Clinic The WCFC in Madera) who probably will become our European FFI
We had the great opportunity to work with Steve and Stephen that jumped the Pond
from California Republic giving us a solid standard in Formation Flying.
We flew in our local area and in Venice too.
Rebuild Project Update ...jamlip
I've been ignoring the project. My RV-4 ate a cylinder, so I replaced it, did
the hour of power and remembered how much I enjoyed flying just for the sale of
it. So I did a bit more, then went to the Arizona Flying Circus fly in. A few
days later, an RV-7-owning friend visited from the UK and we flew basically all
I really love my RV-4. It's that wonderful combination of being easy to fly but
tricky to master. It's going to be hard to sell it once the RV-6 is finished.
Anyway, went to the hangar today. Called for fuel and had the guy fill my left
tank two gallons at a time as I calibrated the gauge. Pulled the top hose off
the oil cooler, loosened the spark plugs and pulled the prop through to get oil
pressure. Retightened everything, set the Emag timing, and hit the starter...
My ****ing starter solenoid is dead.
So I hand-propped the motor. After a couple of whumps and bangs it sprang to
life. Oil pressure is good, prop makes all the right noises (I've never owned a
CS prop before). I ran it for ten minutes and shut it off. Major milestone
So now my to-do list looks something like this...
Get a starter that works and fit it to the engine
Install intercom & radio
Patch some of the redundant holes in the firewall with stainless
Fill, calibrate and check right wing tank
Repair the cowling where someone has done a hash job of of the screwed-together
bit at the front
Connect-up nav light wiring
Get a condition inspection
And on my non-urgent list:
Fit gear leg fairings and pressure recovery wheel pants (I have all the parts)
Make covers for seat cushions (the old ones are basically turning to dust)
I'd also really like to fit electric trim to this - since I removed the centre
console thing under the panel, the cable is all in the way and looks ugly as
It looks like there was a kit available some time ago, but the cable part has
been discontinued. Any leads greatly appreciated!

Grapevine, Az Fly-In ...Capt Sandy
More Arizona Flying.
Roy recently tapped in to happenings with the Arizona Pilots association.
There's a Fly-In gathering at Grapevine Airport the third Saturday of every
month during the "cool" season. We decided to go check the place out and see
what was shak'in. The first part of the video captures the following week - note
there are no other planes there, and on the weekend of which I write, there were
a couple tents and planes gathered. The runway was fine - maybe even better
condition than Ajo (base for the winter).
About 30 planes in all. The fly-in is intended to be a camping trip, but the low
night temps dissuaded most, and most - including us - only stayed for lunch.
The airport is REMOTE - no water, no facilities, other than a pot-a-potty,
firewood, fire-rings and a few picnic tables. We learned that the runway was
abandoned, and the Arizona Pilots Association raised PRIVATE funds to have the
runway paved and put in the few amenities that are there.
Most of the planes were certified-type, so the tribe a bit different than our
usual RV tribe. Still, all passionate about aviation, and therefore all great

Any non-VAF free moments Tue/Wed were spent
nibbling away at a 20hr web-based training course for my upcoming sim
extra paper route. From what I've read so far, the Phenom
300 is an amazing aircraft. Started recording the limitations and
memory items on my phone's
app so I can listen to
them in the car via bluetooth through the speakers on drives. This worked
well for me in the past prepping for orals and writtens.
On a tangent (finances), are there any DFW area dentists that read this

require a second mortgage to get a cavity filled <grin>.

Inspection passed! ...kbalch
My RV-14A project (#140494) officially became an
airplane (N114KB) on Saturday.
Thanks to Vic for flying down and giving a thorough
look over my work of the last 21 months. Several
other -14(A) builder friends of mine were in
attendance to familiarize themselves with the
process and I think everyone went home reassured
that it's not a root canal, but a friendly, low-key
look at the airplane. Plus the paperwork, of course.
Lots of paperwork in triplicate.
Between sorting out a lingering P-mag issue (done!),
a prop low-pitch adjustment (to be done tomorrow),
and two days of mid-week rain, I'm hoping to get the
first flight accomplished on Friday.
For those keeping track of such things, I began the
project in late May 2018 and put in just under 1,200
hours of hands-on work (plus, no doubt, the usual
couple hundred hours of unlogged research & reading
time online) on the entirely standard, non-QB, kit.
I'll be flying it unpainted until delivery to the
paint shop after SnF.
Printed Parts and Molds: Part III ...AX-O
Used West system epoxy mixed 5 to 1 with slow hardener.
Items laid on the mold were:
-3 layers of carbon fiber with multiple overlaps on the nose to make that
stronger for a clamp.
-1 layer of peel-ply
-1 layer of perforated plastic
-1 layer of cotton
That was placed inside a hand made bag (plastic and tape, that was another
trick I learned at Catto's place).
A vacuum was placed on the bag via a pump, approx 25 PSI. That entire
assembly was placed under a moving blanket and a small portable heater was
placed inside. That kept the temps inside at 118 deg during the curing
process despite an OAT of 55 deg.
Little dots you see is the resin coming through the perforated plastic.
SUGGESTIONS Please ...Gyrodoug
My vacuum pump died. I want to toss the system. I'm strongly considering
the Garmin G5. But since I already want to upgrade my steam gauge panel, the
vac system death seems like the nudge I need to make some moves.
But I'm a noob with regards to avionics and what talks to what... on the
side... I have an iPad with FlyQ that I'll always have with me as well.
I have an uninstalled TT Digiflight ii I want to install. I also have a
panel mounted Garmin 196 that has to GO!
Do I go with a Garmin G5 and Aera 660 gps to run the autopilot
Double the investment and go with the GRT Horizon 10.1...
YOUR FRIENDLY SUGGESTIONS
Avionics options are truly daunting to think about.
I'm looking forward to your opinions!
Dimpled an extra hole right next to the one I was supposed to dimple.
Thought about pounding it out, then dimple the correct hole and using a
little filler...but I worried the rivet will not set properly and I create
more of a mess of the situation. It's on the VS skin of an RV8A...I can't be
the first idiot in history to ever make this mistake...Any ideas? BTW, I
have learned through this process that my 4 lettered vocabulary is much
greater than anticipated!
Cooling Tips for Cylinder #6 ...RV-10
My #6 CHT is a good 10 -15 degrees higher than any of the other 5
cylinders. The EGT is in line with the others.
Thoughts on opportunities to assist with airflow?
I improved the sealing on the oil door and made some improvements to the
baffles and that helped a bit but looking for more. I also looked in the
area and sealed a bit more on the inboard rear with RTV to force the air
over the cylinder.
My oil temp is running about 180 so I may try to block a bit of the flow to
the cooler and see if that helps.
Hard to believe I
haven't posted an update for a year!
Lots of build progress has occurred.
In the big picture we:
-Completed the sliding canopy (90%), what a job that
was... Just need the latch installed and a couple of
-Completed the wings/Ailerons/flaps including
installation of Autopilot servo and a late decision
to add stall warning.
-Installed the wings on the fuse temporarily to set
all things that required adjustment or rigging or
-Completed the front structure including
installation of the Aerotronics panel. Enough wiring
was completed to power the panel to see the pretty
lights and display.
-Installed aileron trim servo and Altitude hold
-Purchased the Van's re-designed front engine and
gear leg mount. Managed to find a guy who needed my
original design parts and sold them to him. The new
parts installed nicely.
-Installed the tail feathers to set rigging, cables,
etc. It will come back off for paintwork.
-And the exciting installation of the Poplar Grove
assembled O-320. That really added some visual
We accomplished this among other activities like
flying our vintage 1946 Cessna 120, restoring a 1972
Triumph 500, Airventure Oshkosh, Motorcycle trips,
and numerous other things in life. N951AC is coming
along well. We're currently wiring firewall foreward,
want to get that done of course before installing
the forward skin. Then will get up on the mains, the
next big visual progress item.
Not RV, but a lot of RV folks in this area
have an interest. ...like me.

Flight with Leo
On Friday I was invited to fly with Leo Knowlden as
he flew off his last few hours of Phase 1.
Departed KPTK to
KRNP for fuel, then wandered around Michigan within
the borders of his 50nm radius before returning for
pattern work. Took a break for lunch, then out to
overfly Y47 and 1D2 before calling it a day. Almost
four hours of flying, and loved every minute. Took
hundreds of photos and hours of video; I'll share
just a taste here. Thanks Leo!

Needle Moves a Bit
Thanks to the help
of Danny King (he has done this screen upgrade in
his RV-8). The new G3X screen holes are
widened, the new mounting holes have been drilled,
the new nutplates have been riveted in. Touch
screen functionality is on the horizon. Slow
(all due to me), but progress nonetheless....
3D Printed Parts and Molds ...AX-O
The next phase was to plan out the work. This is
similar to painting. The better work you do on the
front side, the better the part ends up at the end.
I cut the carbon fiber are required to cover the
mold. This particular carbon fiber is the left over
stuff from my Formula One race plane. Side note:
This type of fiber is Bid. But not the standard Bid.
It was discovered by Paulo Iscold while building one
of his race planes. A boat manufacturer had excess
material and they needed to get rid of it. They made
Paulo an offer that he could not refuse. The nice
thing about it is that the fibers are not
interweaved, they are laid on top of each other then
stitched. So you can cut it and pick it up as you
desired and it does not lose its shape. Paulo passed
the gouge to Craig Catto and the fabric is now used
on all his props. And now on to an experiment for an
air filter "box".

Mission Take Momma ...ty1295
Having been a VAF
reader for many years now, and only a flying
airplane owner for 6 months its my turn to return
the favor and hopefully provide some motivation to
keep pounding rivets.
This weekend was the first trip out of phase 1 and a
very successful one.
Bit of backstory first. 5 years ago I meet Becca and
her and I became a blended family of sorts. She has
1 son, and I have 1 son and 1 daughter. Her son will
be 20 next week, and joined the Airforce 1.5 years
My daughter will be 20 in July, and now lives in
Tacoma WA going to school. (where I grew up and
where all my family is)
My son is just 11 and lives here in Louisville
Becca and I got
marries in December after having been "dating" for 5
years. With only 1 child around part time, and the
other 2 off starting life we have a lot of chances
in the future to put this time machine to work. This
weekend was the first having just completed my 40
Hours in my RV9A.
Becca's son Michael is graduating Friday from
Weather school in the AF at Biloxi Mississippi. Both
our schedules were free this past weekend, and the
weather was looking to be perfect for a trip,
stretch the airplanes wings and my own pilot wings
with a long cross country.
Friday morning Becca got up and worked from home
until noon, while I flight planned and quadruple
checked my weather predictions. All was looking
good, the plane has been flying flawless, all lights
Depart KLOU (Bowman Field Louisville Kentucky) at
1pm EST. First leg is to Winchester Municipal
Airport in southern Tennessee for cheap fuel $3.8X.
Being this was only Becca's 3rd time in my airplane,
the just over 1 hours would be a good test.

I chose to make an air filter enclosure. The reason
was because the room in the cowl is restricted to
the mold line, the shape would require contours, it
would force me to find a way to mount the enclosure
and nicely bring that air into the fuel servo. It
would also force me to learn how to use technology
that i don't use.
My previous version was made out of fiber glass and
was made off a wooden mold that belongs to Dave

RV-8 trip from VA to WA ...FlyinTiger
It is always a pleasure to
travel across the greater United States of America in an RV.
Every time it is different. Weather, destination and mission
have driven me along different paths. This time there was a
need to get a newly purchased RV-8 from 53VG, Salmon Farm
Airport, in Virginia, across the Chesapeake Bay, over the
Appalacian Mountains, over the plains of the Mid-West,
through the Rockies and finally across the Cascades, into
the Seattle area for it's new home on Boeing Field (KBFI).
The journey began right here on VAF, with a casual private
message and note in a "wanted" ad right there in the
classifieds. It is a fixed pitch, 180 hp RV-8 with a Garmin
G3X and all the bells and whistles. There was a long line of
interested pilots. It helps to have a commercial pilot's
license and some serious cross country experience. Insurance
requires tail wheel time and time flying an RV-8.
Overall the trip took 17.8
hours of flight time over the course of three days. I
stopped short of the Seattle side of the mountains to meet
the new owner for transition training. This RV-8 has rudder
extensions for the back seat pilot, a throttle and stick. I
don't know how many have completed their transition training
in an RV-8, but the new owner and I gave it a go. The back
seat of an RV-8 was where I flew my first RV hours with a
CFI RV-8 owner before I solo'd in my RV-4 I bought flying
years ago. Being a CFI and tail wheel instructor helped and
the new owner had 350 hours in a J-3 Cub. We accomplished
his training over three long days. Technically advanced
aircraft, leaning, RV-style wheel landings and cross country
flying/planning were all accomplished and the new owner
solo'd late in the morning on the 3rd day. We then ferried
the -8 to Seattle (KBFI) since we had a break in the weather
allowing us to get it there.

The RV6A and I love Winter
Well, maybe one of
us does... Some ramblings:
being cold when pulling planes out, while risking
life and limb on ice and dealing with snow, winter
is a wonderful time to fly. I haven't cleaned bugs
since about late October. One hasn't truly
experienced their RV in maximum climb mode until
you've flown with really cold temperatures. Today it
wasn't too cold, with the surface temperature about
10F, light winds and clear sky. I should have done a
screen capture (I was too busy grinning, even after
18+ years...), but the VSI was between 2500 and
3000fpm, at a pitch angle of about 15 degrees

Fleeing the cold! Tropical RV Winter
As I'm typing this,
it is 111 degrees F colder than where I was this
time last week (92f vs -19f)! Why do I live here??
We loaded the kiddos and an unreasonable amount of
baggage into the flying family truckster, and flew
down to a FLORIDA BEACH HOUSE that we rented with
some others from our RV10 family!
Here is the first (of two) trip recap videos!
I think I need
help, I need to talk to some people or maybe start
going to group meetings or something. I may have a
So I took my airplane down for annual inspection,
and SDS EM-5 installation. That in itself is a big
upgrade and required cutting a new hole in the panel
for the engine controller. But that hole was going
where my current passenger warning is printed on the
vinyl overlay on the panel. So I would need a new
vinyl overlay to put it somewhere else. Since I have
to pull the entire panel to lay up the vinyl on it,
I might as well make some other changes at the same
time - so I ended up completely recutting the panel
to shift things around to make more real estate, and
added the Dynon autopilot controller and knob panel
while I was at it.
Then this evening I was just doing some deep-diving
into the manuals for some of the hardware already
in, and soon to be going in, to my plane... And I
realized that I can move a couple contacts around to
different locations on my Dynon EMS module, and free
up a high impedance Class C input on pin 31 to
accept a variable voltage signal, that would allow
me to put a high pressure transducer on my oxygen
bottle and magically teleport the bottle pressure
onto my Dynon screens for monitoring - no more
twisting around in the seat and squinting at the
1/4" gauge on the bottle while in flight and trying
to guess how accurate it was. Now I can set an alert
on the Dynon to tell me when the oxygen is running
low, and I can see the actual pressure value. And
then I went onto the Digikey website and bought the
Honeywell transducer to do that. It'll be here on
This has to stop at some point. I mean, literally -
I'm out of available inputs on the Dynon system now,
and they don't make an expansion module for more. It
has to stop. I have to finish this and get it back
in the air.

hang of the process, starting perpendicular to the
back rivet plate, then smoothly pivoting to
perpendicular to the trailing edge wedge in one
motion. After each round of rivets, I eyeballed the
trailing edge to ensure it didn't start creeping out
of straightness. So far so good.
After getting all
the rivets 90% set, I went back over the trailing
edge and finished setting them in the same
every-tenth pattern, checking for straightness along
the way. I ran my fingers along the rivet line,
finishing any that felt like they were proud of the
surface more than others. The final results turned
out better than I expected. I suspect the tank
sealant and the leisurely cure time helped keep
everything together well during the riveting.
Nothing shifted at all. Any tank sealant that
squeezed out was cleaned up with acetone, and the
rudder was put on the shelf with the other
mostly-completed parts. On to priming the elevator
and tailcone parts and waiting for spring. In the
meantime I am starting on a PVC tubing spray booth
in the garage.

I was fully planning on working on my master bath
renovation project but, the wife needed her glasses at work
and we were out of dishwasher tabs. Pie and I loaded up to
deliver the glasses and stop by Wal-mart for dishwasher
tabs. On the way out of Wal-mart I saw several familiar cars
at Burger King for the 3ish coffee break. The hangar talkers
usually meet at BK in the afternoon and Pie was able to
score a couple "sympathy" dollars to buy a soda.
A little hangar talk along with mid 50's led to "I
probably better stir the oil" and a .5 flight with Pie, calm
winds and a greased on wheelie to finish it off.

I feel the need to tell this story so others don't have
First of all a little context. I had been laid up with ankle
surgery and had not flown for the past 3 months. My goal
after being released to full weight bearing was to get my 12
back in the air before my condition inspection which expired
February 1st and charge the Dynon back up battery so I could
do the annual battery test. Excited to finally get back in
the air on a clear cold January day I preflighted the plane,
glanced at the tires (which always look low under the wheel
pants and went flying). After getting the backup battery
charged I returned to the airport and landed. Upon landing I
noticed the plane decelerated faster than normal and taxied
off the runway. While taxiing down the taxi way my plane
made several 360 degree turns around my left main landing
gear. I thought it was my brakes but instead it was my
completely flat left main tire and I was grinding up and
cracking my wheel pant. Laying on a cold frozen taxiway
trying to remove my wheel pant was a total pain, but finally
got it removed. Since I didn't have any appropriate way to
jack up the wheel and was blocking the taxiway I was lucky
the airport staff was able to assist me lifting the wing by
the handhold on the end of the wing while I shoved a dolly
underneath the flat wheel. Wasn't at all keen on how we
lifted the airplane but all went well and towed the airplane
back to the hangar. Turns out I spun the tube. So after a
new tube, some fiberglass repair and color matched paint I
am back in the air. It would have so much easier to lay on
the cold hangar floor and check tire pressure before the

IAS Error ...RV7A Flyer
Flying next to a friend in his new-to-him RV-6A (I
believe he has an O-320 FP prop), I asked why we were going
so damned slow...I was showing 100-110 KIAS, and he was
showing 20 knots or greater *higher*. I *know* my airspeed
is correct, by comparison with numerous other RVs in
formation flights, at all sorts of altitudes and power
settings. So this is a problem with his airspeed. But what?
BOTH his mechanical ASI and his D-10A were showing the same
IAS. He has just had a pitot/static/XPDR cert done and
passed, but I know this won't detect installation error that
can only be found in flight.
He performed some stalls in order to find the *indicated*
stall speed, for safety of flight on T/O and LDG, and says
he stalled at around 65-70 KIAS, clearly way too high.
What could cause this? FWIW, his static ports are flush
rivets, but I've only heard of problems with flush rivets
causing an IAS that is too *low*, and it's almost impossible
to think of an installation error with the *pitot* tube that
would make it read that high.

Fit ...David Paule -3B
The aft deck needs
three holes cut in it for access or lightening or
something. The location of those depends on where
the horizontal stabilizer goes. With the aft deck
clecoed to the longerons, I pulled the stabilizer
down from the rafters and clamped it into position.
Except for fore and aft, I made no effort to align
it. I even left the protective bubble-wrap on.
The forward flange of the inboard nose ribs on both
sides are flush with the skin. These interfered with
the aft top skin, the turtledeck. The interference
was small, maybe .090 spanwise and perhaps 1/4 inch
long, and just on the bottom of the stabilizer. I
trimmed these with a Dremel and a sanding drum,
finishing with a small fine file.
Later, talking with my mentor, I learned that this
is common on RV-4s and Rockets, too.
After clamping the stabilizer in place I measured
where the various mounting parts will have to go and
took this photo.
While I was tempted
to bring the vertical stabilizer down from the
rafters and clamp it on, too, I refrained. We all
know where that would lead: lining these parts up
and hanging the elevators and rudder. One of these
days, but not today. Instead, I put the horizontal
stabilizer back up in the rafters for now.

This past Friday I was offered a part time right seat gig a
couple mornings a week at a local DFW simulator in their Embraer
Maybe the occasional evening. This to aid in my lifelong quest for
continuous family food and shelter, and hopefully some
retirement. So this will be concurrently-running job #3 (VAF
80%, PC-12NG side work 5%, Sim 15%). The life of a self
employed person is never dull <g>.
The second 'interview' was 0700 Friday
in the sim complete with V1 cut and ILS - managed not to
embarrass myself too badly (first V1 cut in a modern sim). Exciting stuff!
The Caravan side jobs last year laid great groundwork.
If I'm honest, our family's RV-6 glass panel really did help prepare me for this -
a LOT of that Phenom panel felt very familiar. I
thought he was crazy when two years ago a friend said if that I
got my instrument and commercial in my RV I could easily get
side work. I guess all this is food for thought if you're
living in the movie 'Office Space' like I was back in the
day. I very much did use my RV, which I thought was a
hobby for years and years, as a vehicle to take a sort of career
side tangent. Another unintended consequence of getting
into the world's greatest hobby!!! You never know where
RVs will lead ;^).
This sim side gig should not affect VAF in any way, but it will give me possible
side work opportunities down the road (you can 'cash in' 80 sim
sessions for a PIC type rating). Self-employed long
enough to jump at those things that reduce financial and
career risk. Grateful and Blessed. Grateful and

to Nogales - More AZ Flying ...Capt Sandy
More Arizona fun! Roy and I heard from a (Cessna
pilot) friend that its an easy trek across the
border to Nogales. The possibility of finding good
street tacos appealed, so we headed that way.
Very fun to fly by Kit Peak observatory.
There's no courtesy car at the Nogales airport. I
negotiated a round trip taxi fare. There is a circle
drive where folks are dropped off and picked up at
the border crossing (lots of shuttle buses to
Tucson). Super easy to walk across the border - in
fact no one looked at our passports.
We walked around town, did a little shopping, and
found a terrific restaurant for lunch. We did not
get tacos. Always a good sign when we are the only
gringos in the place.
Lunch for both of us was $12 (plus tip)
Purchased two Mexican "hoodies" $20
Taxi to and from $40
Fuel... well, let's swag $75 (round trip from Ajo)
Pretty close to a $100 hamburger, but tons more fun.
(Note - getting back to the U.S. was not so easy.
Global Entry cards made it easier.)
On our way back we flew over a mine just south of
Tucson, that was so huge, the entire state of
Delaware would probably fit inside. There are many
open pit mines in Arizona, but that was definitely
one of the biggest we've seen.

RV-3B Status Report ...David Paule
Waiting for drywall compound, aka "mud," to dry
means that I needed to find something else to do for
a while. The F-319 (or it might be F-317 or F-318,
it's called all of those. But on drawing 22, it's
F-319) aft deck was cut out a while ago but not
drilled for installation. It's intended to be
riveted to the longerons and the F-309 bulkhead. On
my plane, it'll be attached with screws so that I
can remove it for access to the area.
I measured where the holes should be and marked some
to avoid drilling until later, just in case the
horizontal stabilizer blocks a portion. Then since
the .040 aft deck was opaque and I couldn't verify
the longerons under it, I overlaid a bit of that
.030 Lexan that I'm using as patterns and
transferred the hole locates to that. Placing it
over the longerons, it was obvious that I needed to
shift the hole locations just a bit outboard for
better edge distance. No problem, since I could see
exactly where to put them.
The .030 Lexan is sourced at McMaster. It comes with
a matt plastic protective layer, much like the blue
vinyl we enjoy so much, except that it's
translucent. It easily holds the Sharpie marks and
the sheet is stiff enough that It makes superb
Once the Lexan template was overlaid on the aft
deck, I used my handy Verits optical hole punch to
punch through the Lexan into the aft deck. The next
step was to drill the holes to #50. Why #50? Because
that's small enough that if necessary, I can walk
the hole to a slightly better location, and also
because a Sharpie just fits and I was able to mark
the longerons with the hole locations.
Removing the aft deck, I checked the hole locations
on the longerons and verified that they were
acceptable. Then I pilot-drilled through both the
aft deck and the longerons with a #4The large access
holes still need to be made.

New optional kit: ACCESS PANEL KIT for 7/9/10/14 ...mothership
There's a new optional kit available to order form
the Van's web store as of last night. We have
several in stock now. It's called "ACCESS PANEL KIT"
and is designed for use on the RV-7/9/10/14. It can
be used during new construction, or as a retrofit
installation (in which case you'll drill out two
applicable rivets so you can fit the template).
The kit sells for $19.00, so let's face it, it's a
freakin' bargain. Try that, certified world!
This particular kit
was initially the work of our friend Joe Blank, who
worked in technical support here at Van's and
unfortunately passed away a few years ago. We were
able to pick up his work and finish it off so we can
share it with you.
This kit was created in response to customer
desires/requests over the years. Our engineering
team has worked recently to select and deliver a
handful of these smaller enhancement requests when
they can find a few cycles (and that doesn't happen
often - did I mention we are hiring engineers?) with
the goal of delivering options that people can
choose from if they wish. Other recent examples
include this kit, the cowl louvers kit, the AHARS
mounting bracket kit, RV-12 step plugs and optional
style throttle handle, etc. You'll find those on our
web store in the "New Products" section.
What this kit does: Allows the builder to put a
couple of access panels in the skin ahead of the
windscreen, which can be removed in the event
there's a need to get into the area between the
firewall and the subpanel located at the back of the
avionics bay. Some builders want this so they can
get access without having to contort themselves
upside down under the instrument panel while doing
maintenance. You do need to use a sealant when
installing the panels, so the primary tradeoffs here
are easier access vs. the potential for leaks if not
properly sealed when closed up.
The instructions page (OP-43) is linked from the
kit's web store page, and that document should
answer any questions you have about how one applies
this kit and how the parts fit, etc. There are
template instructions for each of the airplanes it
applies to, all explained in the OP-43 document.
Again, this kit is designed for and includes
templates for the RV-7/7A, RV-9/9A, RV-10, and

100% satisfaction receiving my Airworthy
Time to Build ...asw20c
I figure it's time
to re-calibrate my expectations again. I'm building
an RV14A slow-build, and currently have over 1100
hours expended, and I'm only just now getting close
to finishing the wings. Granted I had to build the
flaps twice and lost about 3 months doing so, but
the Van's website says the modern matched-hole RV14
kit might take someone 1000-1300 hours to complete.
Based on my experience so far, that is wildly
optimistic. I consider myself a very careful
builder, but not obsessive. In other words, I want
everything to be airworthy, but gave up on perfect a
long time ago. Mine will be a very capable aircraft
(i.e. autopilot and fully IFR), but I'm not adding
any capability that most other builders aren't. So
far the only thing I've done that is "off plans" is
installing the heated pitot with AOA, and yes, that
ended up taking a lot more time than I would have
guessed. I'm also priming everything that is
interior to the aircraft, so I know that is adding
to the build-time, but I figure it will be well
worth the investment when I'm too old to fly anymore
and it comes time to sell.
Looking ahead to what is left (fuselage, engine,
avionics), and basing it on my progress to date, I'm
guessing I will have at least 2000 hours or more
before it leaves the ground. I'm even planning on
leaving it unpainted until after it has been flying
and all the bugs worked out so paint isn't factored
into the build time. So, what's a realistic build
time for the 14A? Just curious what other builders
expended now that we have several 14s flying.

Ok am so perplexed
by this. I believe my RPM sensor is built into the
Plasma II+ CDI with Direct Crank Sensor. Would that
be correct. I haven't not been able to trace a RPM
sensor anywhere else. I am running a Slick Mag and
the Light speed. for the 4-500 hours my RPM gauge
was spot on, now it has been slowly becoming more
erratic, now bouncing between 0-3000 (it is def just
just sensor/monitor, and not prop). It is wired
through my GRT 4000 and and the GRT Horizon WS
screens with the first problems showing at the GRT
4000. I have cleaned all the spark plug wires and
thought that might have fixed it but to no avail.
Now I am thinking it may be the Direct Crank sensor
and a bad electrical lead (however the engine is
running great and mag checks are normal).
What am I missing? Sometimes I hate electronics.

Q: I figure
there are folks on this forum that understand
antenna voodoo and can explain something that makes
no sense to me. When I started on my slow-build
wings, I knew that I wanted ground-based navaids as
a backup for satellite navigation and approaches;
i.e I wanted to be able to navigate by VOR and make
ILS approaches if I had to. Stein was happy to sell
me a Bob Archer VOR antenna that fits in the wingtip
(pick one) that they said would do VOR navigation
and ILS approaches.
Fast forward and I'm now at the stage where it is
time to install the antenna. I did a quick internet
search and found that VOR frequencies are 108-118
MHz, and the instructions that came with the antenna
say it covers that range and more (I think
108-136MHz) so I know it is good for both VOR
navigation as well as localizers. However glide
slope frequencies are 329-335 MHz which clearly this
antenna was not designed to receive.
I called Stein today to ask them about this and they
said that if you have a modern navigator, like a
GTN650, that it is able to sort out the localizer
and glide slope frequencies from this one antenna
and that they said other people have been using
these same antennas with no complaints.
Can anyone explain this? Is there a misunderstanding
between me and Stein? Can anyone here vouch for the
fact that they have one of these antennas and can
make an ILS approach? i.e. a PRECISION
A: The Glide
slope frequency is near the third harmonic of the
localizer frequency and antennas perform fairly well
on odd harmonics, an antenna designed for 108 to 118
MHz will also be useful on 329.3 to 335.0 MHz.
The ground based Glide Slope antenna beams most of
the 40 watt signal toward the aircraft which is only
about 5 miles away so it does not take much of an
antenna to receive the signal.
A: As Don
said, antennas that are resonant at half-wavelength
are also resonant at 3/2, 5/2, etc., wavelengths, so
they work well at 330 MHz. The 50 ohm matching
network may be off a bit, but, as Don said, the GS
is relatively strong. There are 1000's of flying
airplanes with dipoles for 110 MHz up on their tails
that also use the same antenna for 330 MHz GS. My
SL30 doesn't even have a separate GS antenna input -
it expects to use the nav antenna. BTW, I have an
Archer in my wingtip, it works fine - vor, loc, and

indication for that. Ambient temperature was 82

forward kit I received the 4x isolator kits which
each included a large flat washer which is under the
head of all 4 bolts and mounts, and then separately
with the engine mounting bolts in the Vans kit there
were 2 slightly smaller diameter large washers
included, as you can see in the second photo.
My thoughts are
that I could use these 2 washers on the front side
of the BOTTOM isolators to space the engine mounting
lugs out and clear the sump casting .. but I am
conscious I could be adding up-thrust by doing so.

I enjoy diving into and learning. As such I want to

learn. I am well connected in my local aviation
community via my work (in aviation) and have several
people who have built many planes to access for help
and guidance. I wanted to come here to ask a few

solo but I want the ability to take a passenger in
relative comfort and still fit a bag for each of us

platform and am looking for suggestions for

build needs to be friendly to someone without 1000s
5) I plan to buy the kits in succession, that is I
plan to buy one kit and as I build it I will save
for the next. So the air frame will be paid for when
complete but I need to figure out financing to
afford engine, avionics and prop. I am an engineer
so I have some means but im not in a position to
rock up to lycoming with 37k in cash for an engine.
So I am looking for advice on what RV is right, and
then what Avionics, engine, and prop to pair with
that RV to best fit my mission as well as advice on
how you paid for your project.
Panel with Lighting Now ...Dave Ford
Audio Yaw Cues ...Vac
To avoid an
unintentional loss of control, the pilot has to
properly control AOA, sideslip and energy. Our basic
tone logic addresses AOA and energy; so recently,
we've begun experimenting with 3D (stereo) audio
cuing to move the tone with the ball in the
slip/skid indicator to provide yaw (sideslip) cues.
Turns out the human brain is remarkably good at
picking out the direction that a sound comes from.
In this case, the Gen 2 box uses EFIS input or
internal accelerometers to measure yaw, and when yaw
is present "slew" the sound of the tone to provide
the same information as the ball, i.e., what rudder
input is required to eliminate sideslip. To minimize
sideslip, you "step on the tone" the same way you
"step on the ball" to center it up.
requires either a stereo ICS or stereo headphones
with bluetooth capability. The gain (i.e., how much
and how perceptibly the tone moves) is adjustable.
Since I'm used to flying the tone, my preference is
subtle, accurate cueing; but some folks might prefer
more (or less) perceptible shift.
Here's a short video clip of the system in action
(you have to use a stereo speakers/headset/ear buds
to hear the tone shift): https://youtu.be/3HRWToFA0dM.
In some of the video, it's not possible to see the
actual ball in the EFIS display due to lighting

shadow on the instrument panel is helpful as is

slider which goes inside the canopy frame and is
springloaded. It is hold in place with the AN525
screw and can slide a litle more than 1/8 of an
inch. The slider is held in the up position with a
springloaded round handle which locks itself in a
small cutout in the canopy frame. Pulling the handle
out a bit lets the slider pushed down by it's spring
and a locking pin locks the canopy in a drilled hole
to the C-657 Canopy Roller Track. The locking pin is
actually a set screw and can be adjusted with an
Allen key from the inside.
Flight at Jay Pratt's RV Central
My RV Weekend
I flew my homeward
commute on Friday afternoon in the Carolina ugliness
that Catmandu mentioned in his post.
Preflight was interesting in the high wind. I had to
think about which tiedown to leave for last so I
could unhook it and scramble into the cockpit to get
my feet on the brakes.
Fully moderate turbulence as forecast but it
slackened a bit west of Winston (INT) which reduced
the workload for about 15 minutes. It started
picking back up as I approached the mountains. The
Mt. Mitchell complex looked down right menacing.
Dark. Rocks all the way into the shredded cloud
I hedged south of my normal route to distance myself
from them. I've been severely banged around by that
set of mountains before.
Landed with little fanfare. The AVL valley really
guides the wind straight down the runway. Parked and
plugged in the heater.
This morning, on the commute out I matched my
highest groundspeed at 230 kts with a glass smooth
tailwind. Not nearly as high as others have done but
it did make me smile.

N84TH Flies! ...sapeloson
April 23rd, 2010 the tail
kit for my RV8 arrived. After almost 10 years of building,
she flew for the first time yesterday. Even though I have
had my transition training and are quilified to fly her. I
don't have the tailwheel experience nor the understaning of
the intracacies of engine performance "should and should
not's". Knowing I would have Vic Syracuse be the DAR, I had
him come down a few years ago to make sure I was headed in
the right direction.
Last month when I put in the paperwork
for an inspection, I asked if he would be the "test pilot"
for my maiden voyage, he agreed. Yesterday, I received my
"airworthiness certificate" and Vic flew the plane. All was
good! I plan to get a few more hours of training over the
next few weeks and begin phase 1.
Huge shout out to Vic and "BaseLeg Aviation" for keeping me
headed in the right direction!

Mud on Foam
After some more work shaping the foam, I was ready to seal
it. The main issue was that I'd shaped it a bit too far on
the sides in the middle, losing some of the compound
curvature that you ca see in the top center. I needed to
build that up and fill in some gaps that remained in the
Drywall compound is the
answer. It allows a build-up, the consistency is the same
across multiple layers and that avoids sanding
discontinuities. Also, it's cheap and I didn't have to mix
it. Normally, I would not permit this anywhere on the plane,
but since this is a mold, not a flight part, it's okay here.
This is after I'd just started on the right side.
Previously, I'd verified that the drywall compound will
stick to the foam. I'm just using a yellow plastic epoxy
squeegee for this instead of my drywall tools. They can't
handle compound curves.
James Aircraft Update
James Aircraft, home of the
Sam James Holy Cowl has had a tremendous year of change.
Mark and I, Mike, purchased the company from Sam and Will
James in February of last year. I thought it would be good
to update everyone on what's been happening with the company
since we acquired it.
Mark and I both have nothing but gratitude to both Sam and
Will James whom we purchased the company from. They are
awesome people and have been there for us any time we have
called for help or just to chat. Sam is now officially
retired and refurbishing his boat at his home in Florida.
Will moved to Vermont and is enjoying a life of nature, cold
weather, and snow.
After purchasing the
company, we moved everything from Sam's place in Florida up
to Maryland and set up a new shop. By the time this was
accomplished we were well into May and sitting on a huge
backlog of orders that had accumulated since well before we
took over. This presented some extreme challenges for us.
Sam and Will spent a week training us in Florida but we
still had a lot of learning to do on the product
manufacturing techniques and on accelerating production
throughput. All this had to be accomplished while more
orders continued coming in.
In our first six months we manufactured and shipped a large
number of cowls, plenums, induction systems, and wheel pants
to customers all over the US, Canada, Europe, Australia, and
New Zealand. Our customers included builders of RV's,
Mustang II, Glasstar, Glassair, Bearhawk, a variety of
canards, Reno air racers, an air show performer and another
kit manufacturer. With the help of our distributor's tech
rep, we re-evaluated the resins and processes that we were
using. One of the big changes that we made was to move from
a very difficult to work with high temperature epoxy resin
used on the plenums to a hard to find and obtain high
temperature vinyl ester resin that retains the strength and
heat characteristics while at the same time reducing weight
and working viscosity. This helped significantly in wetting
out the fabric and in improving product quality. It also
lays the foundation for moving to vacuum infusion.
We have a number of changes and projects on our plate right
- We very quickly outgrew the relatively small space that we
have been leasing in a large community hangar shared with a
maintenance shop and aircraft owners. On March 1st we will
be moving into our own substantially larger and fully
insulated hangar which will house the business and our two
RV's. While we may have to temporarily reduce our production
volume during this move, the new facility will benefit us
tremendously as we scale up our production volume.
- We are also collaborating with a couple builders in the
design and development of a cowl for the RV14 and RV10.
Computer aided design and simulation will be used during the
development of these new products.
- We are sourcing new materials and resins to improve
product quality and gain efficiencies in production.
- Several molds that we have been using need design
improvements or are at the end of their useful life so we
are making new molds that can be used for vacuum infusion of
fiberglass and carbon fiber parts.
- We have plans to purchase a larger curing oven so that we
properly ramp cure some of the resins we are moving to and
also the ability to produce parts from carbon fiber prepreg.
At times we get an abundance of calls and emails which we
try to get answered as quickly as possible. Please give us a
ring back if you have not received a response from us in a
reasonable time. It is difficult for us to break away while
manufacturing parts so please leave us a message if you get
Thank you to all our customers and if you plan on becoming
one please order them early in your build. There is
currently about a six-month backlog in our production queue.
We do not take any payment up front so it does not hurt to
get your name on the production list as early as possible.
We look forward to the future and to the opportunity to
provide products that perform well and look great.

I finally replaced my
Lowrance with a Samsung tablet for ADSB In and Out using

an EE so lots of the jargon was foreign to me. As each step
was accomplished, and as my understanding of the components
improved, I constantly rewrote the narrative. Anyone with
the same equipment who would like a copy of my narrative, PM
me and I will send it out.

The Mystery of the Missing Brake Fluid ...bkervaski
Last October during a taxi I noticed my brakes getting
Upon inspection, the brake reservoir was empty.
This is the Beringer brake system.
I check the brake fluid at least once per month and the last
check, a few weeks prior during the annual, it was the
normal 3/4 full.
Here's the mystery: Beyond one tiny drop on the reservoir
connection there was no leaked break fluid anywhere. I
checked everything. Every connector in the airplane, the
entire path of the lines. Nothing. Just a small drop on the
back end of the reservoir but nothing pooled up. No stains
in the plane or on the hangar floor. Nothing.
I didn't post then because I wanted to see if it would
happen again and it hasn't, the reservoir has maintained
The only conclusion I can reach is that perhaps there was a
large volume of air somewhere in the system that finally
cleared itself, however, prior to the magic disappearing

quit while practicing stalls ...Strappe
On a clear sunny
Groundhog and Super Bowl Day I went for the first
test flight to set up SV-AP-Panel and AoA system.
Barometer was 27.81, OAT 54℉ on the ground, winds
Dynon Skyview Touch with 2 axis-AP
SV-Knob Panel (installed 5/2019)
Gen3 HACman mixture control (installed 7/2019)
Silent Hektik VR (installed 9/2019)
SV-AP-Panel (installed 11/2019)
AoA retrofit kit (installation finished 1/28/2020 -
required removal of wings and fuel tank.
In level flight at 6500 MSL, OAT 29℉, electric fuel
pump on, HACman mixture set to full rich, I lowered
engine RPM to 3,000 and began first stall to
calibrate AoA. With RPM at 2500, nose up steeply and
near the stall, the engine RPM fell and the engine
began to run roughly. I lowered the nose right at
full stall, logged the stall in Skyview (of course),
lowered the nose, eased throttle forward then
leveled out after full recovery. Engine recovered
full RPM and smooth running, but only after 30-45
seconds of roughness with nose level.
I decided to add a second stall to the calibration.
Entry to stall was similar, but of a longer duration
and at full stall, RPM began to fall and in 2-3
seconds, the engine quit. By full recovery from the
stall, the prop stopped. Initial attempts at using
the starter failed to restart the engine. I did the
usual system checks (fuel on, electric pump audibly
clattering away and making good fuel pressure, all
active engine monitors in the green, HACman still
full rich) and began to set up an approach and
landing at the paved airport less than 3 miles away.
My altitude by then was over 5,000 MSL, about 3500
AGL. After several more attempts with the starter,
the engine roared to life after about 3 minutes in
glider mode. I re-established cruise RPM slowly and
leveled off, only to have the engine quit again.
This time it restarted within 10 seconds or so of
running the starter.
I flew back to my home airport (> 30 miles away)
without further incident, did a full stall landing.
The newly calibrated AoA and the stall warning
agreed on the moment lift was lost. The engine ran
fine during landing stall and taxi.
The electric fuel pump appears to be running fine,
with good pressure at all times (although, I did not
check it during the drop in RPM/rough running
moments; only after stall recovery). The fuel tank
was full at takeoff and I have no evidence of any
leaks in the fuel system, but I have not yet removed
the cowling or floor boards to do a full inspection.
I completed last CI in late August and two carb
floats were heavy, so I replace them with new.
I emailed Green Sky Adventures on Monday and am
awaiting a reply. One local RV-12 owner with HACman
installed has never noted any issues like this.
Reading the install instructions and operational
information (and warnings) however, engine stoppage
from what they state are incorrect installations can
occur. Obviously, I need to check the entire fuel
system if I can't find an issue with the mixture
controller. Carb floats seem always on the list of
suspects. This doesn't seem like an ignition issue,
however. Or does it?
I'm looking for suggestions. I do not want to fly
the plane until this is resolved.

3-Blade Sensenich Prop - Now available for RV-12is/RV-12
Van's has published updated
RV-12/12iS powerplant kit order forms, a new plans section
(47AiS/U) and a service letter (SL 19-12-31), all of which
are related to the now-available optional 3-blade Sensenich
We displayed this prop on a stand in our booth at Oshkosh
last year and flew it to the show on one of our factory
aircraft. It garnered quite a bit of interest. Now that the
engineering has been completed and testing of the final
install package is all wrapped up, the three-blade prop and
spinner kit is available to order as an option on new
powerplant kit orders (you'll get to choose either a
two-blade or three-blade prop when you order). You can also
place a stand-alone order for the prop without the rest of
the Powerplant kit (just use the powerplant kit order form
and select only the 3-blade prop option in that case).
Note that when building your airplane, in order to register
ELSA the parts - including the propeller - must be bought
directly from Van's and tracked in our records under that
aircraft serial number. Once an aircraft has been licensed
and registered ELSA you may, of course, make any changes as
People will, of course, want to know what's different
between the two-blade and three-blade prop. Our testing
experience showed that:
Cruise performance was the same (at lower altitudes)
Climb performance was greater
Propeller braking action was slightly greater, which allowed
a slightly steeper descent angle in the pattern
The sound/pitch is different, although the measured noise
level is about the same (they are the same diameter).
And, of course, there's the aesthetics: The blades are wider
on the two-blade prop. Some folks prefer the look of three
blades, while others prefer two. Some people like a thinner
blade, while others prefer the "beefier" look.
Big ole dent in prop leading edge ...JackinMichigan
...I noticed this
little surprise during my condition inspection. It
must have just happened because I didn't notice it
during my last preflight, and I make it a point to
check the prop leading edges.
This is an MT constant speed 3-blade composite prop
with all of 53 hours on it. The edges don't feel
sharp and it didn't break thru the protective
aluminum leading edge, so what should I do about
this? Do I do anything?

I pulled the cowl and mapped out my electrical
system as needed. I have no grounds returning to the
firewall in groups or individually. My battery is
grounded to the air frame at the upper, passenger
side engine mount bolt. It does not project in any
way by jumper or otherwise, to anywhere on the
cockpit side of the firewall. So my individual
ground wires seemingly have to be terminated at some
location on the air frame (in groups or
I am going to attempt to cut open some of the wire
bundles this weekend so I can attempt to trace a
ground from a single avionics device, from the unit
to its termination point. This has been very
difficult so far but I hope that opening some of the
bundles of wire might help in that regard.
I have 2 different types of "junctions" for groups
of wires. One is a metal unit that wires screw into
at individual screws. If I check continuity from any
single screw, wire, or the junction unit itself, to
the firewall, they indicate ground. I presume I am
not learning anything from this other than that that
block of wires is grounded "locally" thought the
metal block. The other type is a plastic looking
unit with pairs of screws in two rows. Some of these
screws indicate ground while others do not. So I am
assuming these pairs of screws are merely isolated
links in some part of a given circuit. Some ground
and some power. These can probably be viewed in my
original pics. Some have already commented on them.
My question is is this a normal and acceptable way
to wire a plane's electrical system? And if so, what
is the logic? If everything is grounded locally to
the air frame, I would presume you would have a ton
of noise in the system.
When I began trying to figure this ADS-B install
out, I figured I would just have to trace one
installed ground wire to locate a good ground for
ADS-B. But it has proven to be much more difficult
than I thought it would be.
Lastly , it seems as though I am not going to
discover a mythical central ground. If that's the
case, Should I just ground the ADS-B next to the
unit, or possibly all the way back to the firewall
near the battery??
Sorry for the long and confused post. Thanks again.

The most intense training experience I've ever had.

Roll Bar Bolts
I'm suprised you
couldn't hear my cursing all the way from Estes
The Aft bolt (1/4") on each side of the 7 roll bar
has a washer and nut installed under the longeron.
It has a special aluminum shim then washer then nut.
It was easy with the fuse upside down but right side
up, gravity is not helping. Somehow this has to be
done in a space barely big enough to get my
catcher's mit fingers in the space. The aluminum
shim stays put pretty well without persuasion, but
the washer wants to fall off before the nut can be
slipped into place.*
I needed a trick. Neodymium magnet to the rescue.
This time two of the uncoated magnets. Place the
magnet on the bolt head. Slip a washer on the bolt
and it stays put. Slip the nut in the space. Say a
prayer to the Nut Gods. Stick your toungue out so
words don't offend same Gods, then gently rotate the
bolt with an open end wrench (magnets are stuck on
the bolt) till it grabs a couple threads.
Yes, I've heard of builders glueing the assembly
then turning the bolt into the part, but one mistake
there and a cross thread nightmare ruins the day.
After years of wrenching in cars, I learned to
always use human fingers to feel the threads engage

Upholstery input sought ...Bill Boyd
deciding on interior for the -10 build now. Some
time back I snagged a "deal" on rear seat back
frames originally made by Cleaveland but no longer
in production. I was hoping to have these covered
and have rear 60-40 sets matching the profile of the
fronts. After research I've learned that none of the
major vendors besides DJ at Cleaveland will do this
for a price within market.
I have enjoyed talking with DJ and feel she would be
easy to work with. I'm just not sure I like the way
her 10 seats look in photos. Something about the
horizontal seams in the center part of the seat
backs doesn't look right to me somehow. I think
since I'm not willing to experiment with finding a
local shop to do the rears and try to
match/complement aircraft vendor-done front seats,
I'd be better off selling these rear seat frames
unless I have Cleaveland do all four seats. DJ has
offered to bid just doing the rear seats. AeroSport
has declined to do only the front seats - no reason
offered. South Florida Sport Aviation never answers
the phone and has not returned by voicemail message
from a week ago.
This has proven to be the most challenging part of
the build to out-source professionally, and I really
don't want to be stuck with buyer's remorse on this.
I'd appreciate private message honest feedback about
RV-10 seat experience from those who've 'been
there.' I'm not interested in calling anyone out or
starting a vendor-bashing thread. I'm sure they're
all great folks who bring unique things to the
table. I just want some good honest feedback before
I jump in. PM me if you have some advice. Answer
publicly if you wish, just be constructive.

currently in the process of conducting my annual
inspection and installing the SDS EM5 engine
management hardware, and associated with that I
needed to pull the flywheel to drill and tap it for
trigger magnets. To pull the flywheel I need to
loosen the alternator belt first, and as soon as I
took a look at the alternator, before I even
loosened the first bolt I knew something wasn't
right. The belt angle was wrong and the alternator
was obviously not hanging correctly, and as soon as
I started to loosen the first bolt the problem was
Rudder malfunction??? ...mturnerb
today the "genius" operator of my aircraft learned
something new. I did my usual pre-flight and started
up the airplane. On the taxiway by my hangar
(stopped and holding brakes) I did part of the
checklist that I don't like to do in the run-up area
as the airport is crazy busy on a beautiful VFR day
like today. One of those items is an autopilot test
(G3X touch) to check that I can overcome the servos
and that my red button (autopilot disconnect) works
as it's supposed to. So far, so good. My next action
is always to turn off the flight director as the G3X
autopilot leaves it on and I find it annoying while
taxiing. Today I forgot to hit that button until a
bit farther down the taxiway.
As I approached the point on the taxiway where I
usually contact ground control (they have no visual
contact with hangar area taxiways), I noticed that
my rudder pedals felt "stuck": gentle force against
the pedals gave me the sensation that the cables
were caught/trapped. Strange, since I checked them
on preflight and they seemed fine, and felt good
when I got in the airplane to start up.
So I called up ground control and taxied back to my
hangar using brakes. As I turned on the taxiway to
my hangar I turned off the avionics and autopilot
switches. Suddenly, rudder pedals are "free and
correct". It's about this point that I realize I hit
the yaw damper button instead of the flight director
button (or both, not sure). Yaw damper servo engaged
on the ground pretty much feels like a stuck rudder
cable, I learned today!
It was a perfect day for the flight that then ensued
after shutting down, checking everything on the
ground fully, and making my way back to the starting

Leaking primer solenoid ...Joe
On a refurbishment
project I installed a new fuel primer valve, a
Parker 12V solenoid valve from Aircraft Spruce (part
number 05-04368). From the get-go, in the "OFF"
position (no voltage to the solenoid) it leaked
badly causing the engine to run excessively rich.
I removed it and can verify it leaks sometimes and
it seals at other times. Aircraft Spruce is willing
to give me an RMA but it will take 4-6 weeks to hear
back from Parker and issue a credit if they deem it
defective. I'm inclined to just order another and
get on with it but first ...
My question for experienced users of this particular
valve is this: could it be an installation issue
(e.g. is one port an input and the other an output).
An additional question: how does one
non-destructively open this particular valve to
examine the viton plunger and its sealing surfaces?
I don't want to apply any heat to break the locktite
for fear of melting something inside.

Journey of Self Discovery ...frankbrown
Building a plane is a Journey of self discovery.
What I've learned so far:
*I can't rivet.
*Vans is really great with sending new parts!
*Changing one thing can really lead to a lot of work.
*I need to loose 50 lbs to crawl around the fuse like a teenager.
Decided to go with fuel injection.
Led to new fuel pump, learning soft tubing skills, cutting and building for
new housing for new fuel pump, changing to electric trim since I would need
a larger trim cable any way.
New lower cowl for the FI engine is also in my future.
I would say '1 step forward, 2 steps back....but I have not gone forward'
I have been soldering my Fly LED's for the wing tip lights and that has been
really cool. That is a really great kit if anyone is thinking of them.
What will I learn next week?
Been five years since the
last visit to the eye doctor. I have an interview this

Tube Update ...Dean Pichon
I just fixed my flat by replacing both tubes, both tires,
(and brake pads for good measure). I inflated both old tubes
(the one that flatted and the one on the other side) to 8-10
psi. Neither showed a leak by submerging. After 7 days, I
could not discern a pressure difference between the two.
It's still a mystery to me.
To what level can a tube without a tire be pressurized
without rupturing the tube?
Inspection - Do I Need a New Distributor Block Assembly? ...avrojockey
I'm upgrading one mag to a P-mag and need to swap the
tach pickup to the left mag. Since the plug was hard to get
too I decided to remove the mag and do a 500-hr inspection
All looked good but there is obvious contact happening
between the electrode towers and the electrode finger on the
distributor gear. The electrode finger on the distributor
gear is not loose and there's no signs of cracking in the
gear. Also, there's no cracking in the distributor block.
There is, however, some slight play in the gear when
assembled in the distributor block, which leads me to
believe the olite bearings are worn.
Does anyone know if contact between the gear electrode and
the distributor towers is cause for replacement? The
overhaul manual is vague...
"Inspect the brass electrode posts for signs of physical
wear. Replace block assembly as necessary."
Manual says bearing should be 0.246 +.002/-.001 so I'm
checking that next.

Pushing and pulling via the prop.
Just getting an idea on if it's bad or not to gently
push/pull the airplane by the root of the prop close to the
spinner to move it around. Airplane in question is an RV-6A
with O-320 H2AD fixed catto prop.
I push and pull my RV-6A by the prop and was told to do so
by my mechanic. Think about it, the prop is pulling the
plane through the air so there is much more load on it when
flying than you could put on it on the ground. Now I do like
you said and push/pull near the hub not way out at the tip,
even though I doubt even that would cause any issues.
Approximate percent of people who use prop to pull their
Hartzell (and others) equipped RV's is 100%
There is a thrust bearing in the engine but on the ground it
has no oil pressure.
If you can push or pull without turning the prop it's
probably ok but if it turns as you are pulling it could
damage the bearing. So why not just push on the cowl and
pull with a tow bar?

that connect the inboard rear rib to the left main spar.
After an Unairworthy Condition Inspection
Was hangar flying with a friend the other day and
the topic of the Annual Inspections and Condition
Inspections came up.
On a Standard Airworthiness airplane the Inspection
is done and there are 2 options that usually happen:
1- the discrepancies (or squawks) get fixed and the
Annual Inspection is signed as Airworthy and
returned to service.
2- the discrepancies get written up (squawk list)
and the logbook is signed as Unairworthy with
discrepancies given to owner. Then at least an A&P
will correct the discrepancies and sign the logbooks
with their certificate as done. That brings the
plane back to Airworthy.
Then we started talking about Experimental
All maintenance on my Experimental plane can be done
by me. I'm not an A&P and don't have a Repairman
certificate of any kind.
In Experimental airplanes the Condition Inspection
must be done by at least an A&P.
Here's were we got stuck. Say an A&P does my
Condition Inspection and finds some deficiencies.
Can he sign the logbook as Unairworthy and give me a
squawk list like a Standard airplane or does he have
to repair anything and sign it as Airworthy?
If he can sign it as Unairworthy and give me a
squawk list, can I fix the squawks and return it to
service or does it have to be another A&P?
Please include FARs with your replies so I can
research it further and learn from you. Thanks !
(*** In MY specific case it would most likely get
fixed by another A&P because depending on what it is
I probably don't have the expertise, but I'm asking
in general terms. ***)

Foam Fun ...David Paule -3B Update
The fiberglass canopy fairing needs to fit the skin, and
there were clecos poking out of it, holding the front top
on. Time to screw it down. On the RV-3B, this skin is
attached with a lot of #8 screws. The side screw holes got
dimpled for #8 screw heads as you'd expect. The instrument
panel flange wasn't wide enough for #8 dimples so I decided
to use NAS8702U1 8-32 screws instead. These screws are
really good: the material is 160 ksi A286, strong enough to
survive a number of installations and removals, corrosion
resistant and very tough - cracks don't propagate easily in
that material. It's the material that many spacecraft screws
are made of.
This particular part number has a #8 body and a #6 head.
I had to get a special dimple die for that, and Cleaveland
In this photo, the instrument panel screw, on the right, is
in a #6 dimple as it should be. But the screws on the bottom
(the side of the fuselage) are #8 dimples and these screws
just don't fit. I included one of the standard #8 screws for
comparison. Since this is merely to temporarily replace some
clecos, the use of the wrong screws here is okay.
Blocked Pitot ...Jpm757
Took off today with my Pitot cover installed. I am

system as a whole. Stopped at a local airport and replaced
my now ragged cover with a new one with a big red banner.
Quick Fuse Update ...Pilotjohns
So I have been working on the tail fairing now that the
tail mechanical attach is done. I figured I would get it
done before the tail comes off. The stock fairing fits
really nice; much better than older posters have led me to
believe. I used the cut lines, but these were too severe in
the rear, so next time, I would leave a little extra there
and trim, fit, trim, fit, etc. Nothing major for mounting,
just takes time to find the underlying holes in the fuse. I
measure the location of the holes in the fuse without the
fairing; added the fairing, marked the hole locations on the
fairing, then drilled a #50, then a 3/32 hole in the
fairing, cleco'd and moved on to the next. Next I will
enlarge the holes to #40, countersink the fiberglass for the
#6 flathead screws, then enlarge the holes to #6, remove the
fairing, and install the riv nuts.

Fuel Tank Leak ...jahoosafat
Hi - My 2013 RV-10 is about to be re-painted,*and I found
multiple fuel leaks on both the right and left tanks just as
I dropped it off at the paint shop in Alabama. I previously
had a few leaks, and my A&P applied epoxy to the tank
exterior in order to avoid the higher cost of removing and
re-sealing the tanks.* This approach worked ... until now.*
My question is what's the best course: 1) Remove the tanks
and send them to Paul Beck (http://www.weepnomorellc.com/),
reinstalling them before final paint work. 2) Remove the
tanks and buy new tanks from Vans, getting an A&P connected
with the paint shop to build and install them.* 3) Something
else?* Since I'm an owner rather than a builder, could
anyone provide info about potential timeframes for
Weepnomore to turn these around (I've emailed Paul and am
waiting to hear back) or a decent A&P to build/install new
tanks?* Thanks for any info!
DanH Annual PIREP
Annual time, so as promised, I stuck a borescope down the

it for a hot leakdown, then took the photo 30~60 minutes
For those new to Lycomings, the horizontal intake sump has
an upper chamber full of oil, and a lower chamber for intake

not pass through the hot oil. Instead, the intake tubes
enter the air plenum from the sides.

underside of the wing clean and the next day there would be

RE: Formation Clinics and Cards? ...Check6
I have had a couple of conversations around Falcon
Flight's Formation Clinic coming up in April. I wanted to
write a universal response:
Stu "Falcon" McCurdy started Falcon Flight in 1993 as a way
to demonstrate the precision and safety of flying in
formation. Falcon Flight was the first FFI team. He would
soon thereafter start FFI (Formation Flying Inc.) to set a
"standard" and get more pilots flying formation safely. I
believe the history and legacy of Falcon Flight continues
because of his dream to teach, demonstrate, and provide a
resource for those motivated to fly formation.
The questions have ranged from "What if I don't want to be a
"Carded pilot"?" to "If I don't have a "Card" I can't be in
the "club". The goal of FFI is Not for everyone to get a
card and we are not a club. I think I can speak for most FFI
formation clinics with the exception of the advanced clinics
which are designed to get pilots carded for Airshows/routines.
So you do NOT have to be a carded pilot to fly formation!
The goal of FFI is spread the precision and standard of
flying formation to those interested in learning a new
skill, training to the same standard and holding those they
fly with to the standard. This allows the pilot to show up
with others that have been trained to the standard to get
together and go formation flying safely - That truly was
"Falcon's" goal! There are lots of reasons to fly formation,
which I will not go into here - that is for a clinic.
There are those who want to get a card as it demonstrates a
lot of energy, effort and training to get "carded" as it is
not an easy process in that it takes time and lots of
practice. But here again the only reason you MUST have a
card is to perform in TFR's and/or Airshows. So if you have
4 RV buddies in this case that have been trained to the FFI
standard and you wanted to go do a local missing man for a
veteran etc. none of you would need a "Card".
Hopefully, this answers some of the questions/perceptions
around RV Formation Clinics and will serve to encourage more
aviators to learn this skill. Please feel free to take a
look at the upcoming Falcon Flight Clinic in the above posts
or any others that are held around the country. I think you
will have lots of fun, be challenged and learn/polish up a

A Little Progress
The swap out of first gen G3X screens with touch models
and other panel love continues in Flash.
You drill out the old rivets and clamp on a steel jig that
shows you where to drill the new holes (and how much of the
corners you need to nibble out). Where's the punch?
I need a 30 and 40 drill bit. I need a sheet so I

The plan was to work on the panel for a

old garage door opener on my side give up the ghost Tuesday.
So, Wednesday was spent installing a factory referb belt driven

improved over the last two decades. No oiling, silent belt drive,
wireless controls, web app and plug in cameras and parking lasers

AOA confession ...sailvi767
As a Navy trained pilot I have had AOA available in most
aircraft I have flown. My first RV was a RV6 with AOA. I
liked it but never had a occasion where I felt it provided
any type of save or a warning that the aircraft was not in
the state I wanted it at. Still I liked having the extra
level of protection.
I purchased a F1 Rocket that did not
have AOA or any stall warning. That bothered me a bit but I
quickly found the aircraft to be very honest and easy to fly
in the patten at the proper speeds. I had planned a panel
upgrade shortly after purchasing it that would include AOA.
In Nov when the aircraft was getting a new panel I
considered dropping the AOA option to avoid a pitot change
and cost. In the end I kept the AOA. (Dynon HDX system with
On Tuesday I was out flying after a frontal
passage. On return to my home field which involves a
slightly overshooting approach as the norm to avoid tall
trees I needed to also compensate for a strong overshooting
crosswind in the pattern. (30 Kts at 1000 ft). On base to
final I found myself with more overshoot than planned and
wrapping the turn up. Normally I would have been at 75 knots
at this point but was actually targeting 80 knots with the
bumpy conditions. Just after crossing the gap in the trees
still turning to align with the runway at about 250 AGL I
got a beep from the Dynon AOA. Unloaded, leveled the wings
and went around. Glancing at the airspeed I was at 67 knots.
In one G flight I get the first AOA beep at 56 Kts. I was
slow, wrapped up and visually 100% outside watching the
trees. I should have abandoned the approach prior to that
point and gone around. I now embarrassingly have my first
AOA save in 7 years of flying RV's.
I don't know how much
margin was left but I am now very glad I went with the AOA
option. I fell into a trap many pilots get into and needed
the AOA tone to jolt me back into reality. Spend the money
and put a AOA system into your aircraft!

My $17 mistake ...bruce
I am building an RV-14A. Over the weekend I made a
mistake that will cost me $17. I have to buy a six foot
length of piano hinge (again). I am pretty sure it is an
error in the plans rather than my own screw-up.
I was wondering if there is a place on VAF for people to log
suspected plans errors. If not, do you think it would be a
Does Van's track possible errors in the plans?
More info on my mistake:
The plans call for the piano hinge for the upper cowling to
have a reference line drawn the length of the hinge 3/16"
behind the hinge eyelets to be used to ensure the hinge is
straight on the firewall. I drew the line where it was
supposed to be. I followed the instructions that said the
line had to be parallel to front of the top skin. I placed
the hinge such that the reference line was exactly on the
front edge of the top skin even though the index hold didn't
line up. I then match drilled each of the holes into the
piano hinge (based on holes that were already in the top
skin). When I took it apart I found that the holes were way
too close to the edge of the piano hinge (only about one
rivet diameter away). The only way for the holes to be in
the center of the "meat" of the hinge would be for the
reference line to be up under the top skin where I wouldn't
be able to see it. So I suspect the plans have the reference
line drawn in the wrong place.
Issues are tracked and investigated ( that is easier to do
if you mention a plans page and step #). There is a
stickied thread at the top of the RV-14 subforum that
has been used to log /report suspected issues.

My RV Weekend ...RV8Squaz
I had a productive weekend.
I departed Thursday morning for a 3-leg day. First was a
stop in Marianna, FL (MAI) to visit Air Prop Specialists.
I've been using this shop for 12+ years. My Hartzell has an
old hub which has an AD that requires an Eddy current
inspection every 100 hours or annual whichever comes first.
In my case it works out to about every 9 months. It's really
not as obtrusive as it sounds. It's about an hour flight,
takes me 5 minutes to remove the spinner, 10 minutes for the
technician to do the inspection, 5 minutes to install the
spinner, and 10 minutes for the paper work. The cost...
let's just say I can do a lot of inspections for the price
of a new prop! I usually combine it with a BBQ lunch or a
visit to the nearby Florida Caverns State Park. Not this
time though; I had places to go and people to see.
The 2nd leg took me to 28J, Palatka Muni to see a couple of
Extra's that were for sale and being re-assembled. It was
great to see them with all of the panels removed so that I
could inspect everything. They looked good!
The 3rd leg (my first VFR leg of the day) took me to PMP,
Pompano Air Park in S. Florida to visit with my brother and
his family for a few days. PMP is home of the Good Year
blimp. My brother and I enjoyed some seriously good donuts.
Yesterday I came back in two legs. Had to depart IFR due
to the Trump TFR in Palm Beach and the weather at my fuel
stop at FIN, Flagler Co Airport just north of Daytona Beach.
I don't normally stop for fuel going to or from S. Florida
but Flagler's fuel was $3.99. I couldn't resist! I had hoped
to see a couple of Extra's at Spruce Creek and St.
Augustine, but I wasn't able to coordinate with the sellers.
BTW, I never experienced any of the proposed GPS outages
across the SE. I finally got past the front just north of
Jacksonville and had a beautiful evening flight home for the
last hour. The 30-40 knots on the nose gave me more time to
enjoy the gorgeous sunset.

Sunday my wife and I took off to Paso Robles for a wine
tasting overnight trip for her birthday weekend. Had a great
tailwind and we got up there in record time. Got to cross
LAX Class Bravo via the Coliseum Route at 8500'. The airport
(KPRB) cleared up to VFR as we got close and then we had
breakfast at the diner on the field, which was excellent
(Joe's one-niner diner). We got our rental car from ACI Jet
and then we hit several wineries and did some other
shopping/dining. Back to the airport diner the next morning
for another great breakfast, then we took off to head home.
Cloudy high overcast with a few low clouds below, and some
brutal headwinds the whole way, so we stayed lower along the

O-320 Help! ...8213C
I am having issues with my EGTs on my O-320 . My mechanic
looked it over and concluded that I needed to have the carb
replaced. So I did, flew, and this was the result. I could
never get #3 cylinder to go under 1500 degrees even in
cruise at full rich and, 2400rpm. My temps are, #1 1380, #2
1260 #3 1510, #4 1378 full rich. On takeoff on the ground it
wouldn't rev past 2200 rpm, where it use to be 2350 with the
old carb. She seemed super gutless in climb out and takeoff
roll. In the climb out now, I saw 1605 and 1590 on #3 and
#4. I'd have to throttle down to 2200-2300 rpm to get #3
into the 1470s in cruise at full rich; she feels real rough
overall and more so on the left mag. I tried different power
n mix settings for about 20 minutes but no change, just
higher EGTs. I had the mags sent off and one was rebuilt
right before all this at the time of the new carb install.
Twice now I have been told she runs great, and the mechanic
has released it like this. On the 1st test flight attempt,
it was backfiring bad on run up with one mag dropping 500,
so I didn't even fly it. They then cleaned the brand-new
plugs which have barley 50hrs on them and richened it some.
I don't understand why the plugs would be fouled already
since I always lean on the ground and always lean out for
cruise but anyway no bad mag check or misfiring with mags
dropping 100 on both L & R. Now still the EGT issue. They
are higher temps then I had before and a greater spread
between hottest and coldest. The other thing is my highest
temp cylinder before the carb was #4 at about around 1500.
Also, when I kill it now, it has a slow drop and no rise at
My compression is mid 70s and had no metal in the oil. The
engine has about 800hrs SMOH. At this time, I had the
4-cylinder EGT gauge installed and I realized it was too hot
and was told to change the old carb out for a new one would
solve that issue. I have flown it 55hrs since the annual and
now decided to go for it and replace the carb in effort to
help those EGTs. I feel like I should have just left it
alone at this point.
My mechanic seems to not be sure what to do right now.
Do I just need someone who knows how to tune this thing or
any other advice out there?
Why would #2 be so much colder?
Why is just once cylinder so hot?
Why the lower RPM on the ground after being richened up?
My 'Sonic Window Tray' ...ArlingtonRV
In the past I had made a diving board by clamping a board

OK, but it was a good bit down the side of the fuselage and

Since gravity has yet to be repealed, anything I knock off
goes right for the wing. Also, I have to be careful not to
hit the flap with the cart. So, while it worked, it was not
RE: The Annual Price Increase ...Greg Hughes
The price adjustments we make, when necessary, generally
take place in the late spring. Last year we were delayed a
month or two. We do everything we can to keep the prices
affordable, in pursuit of why we're here: to make uncommonly
awesome airplanes available and accessible to (relatively)
common people. :^)
Most adjustments are substantially related to changing cost
of materials. The more significant increase that David
referred to was on the RV-3 and RV-4 a few years ago and was
related to cost of manufacturing and support given the lower
volume of kit orders. We had to make an adjustment to not be
underwater, so to speak.
The RV-10 is currently the second most popular kit. No
volume-related issues currently with that one. :^)
We're just working hard to keep pushing them out the door!

known in these parts at videobobk, has not been in
good health the past couple months. I have visited
him in the hospital as much as I could, and after my
latest visit last Tuesday I figured it was time for
an update and some much needed good news! Bob is
back to his old self, ornery, witty, and sharp as
ever! He remarked about the litany on medical
equipment he's been hooked up to, saying he feels
like a transponder with all of the beeping going on!
He should be returning home sometime this week, and
although he still has a long road ahead to get back
to building and running the day to day operations of
Aviation Nation, he has made leaps and bounds and we
are all very encouraged. Although he did not
specifically ask me to post this here, he is
incredibly thankful for the amazing support system
he is surrounded by. God is good!

over to pick up stuff off the wing (and risking
having it roll off)
Could be modified to
compensate for taildragger slope, etc.
I wouldn't put a lot of weight on it, but
screwdrivers, wrenches, small tools and fasteners
should be fine.
BTW, I went all plastic because
metal has a way of finding my paint. I may put some
liner material in the tray to prevent sliding of
tools. A work in progress.

System Holes in Wing Ribs ...iamtheari RV-14
I began drilling the systems holes in my left
wing ribs tonight and realized that I should make
sure that I have enough room for the systems my
plane will have. I am not doing anything that hasn't
been done before, so probably someone has already
sorted this out.
Here's the inventory of what needs to go through the
* Standard wiring harness
* 2 wires in left wing (pitot heat ground, taxi
* 1 wire in right wing (taxi light)
* Coax cable in right wing for nav antenna in
* Pitot and AOA tubing in left wing, all the way to
the subpanel since the ADAHRS will be there
* Garmin magnetometer in left wing ADAHRS mount
I think that I can run the pitot line in the upper
aft systems holes of the left wing all the way to
the root, the AOA line in the lower aft systems
holes, and the nav antenna cable in the lower aft
systems holes of the right wing through the first 8
ribs and the forward systems hole in the remaining 6
The only conflicts I see in that plan come from the
ADAHRS wiring harness, which connects to the
magnetometer in the Garmin installation. That is
supposed to run in the lower aft systems holes in
the second, third, and fourth ribs of the left wing.
It seems likely that the wires will be long enough
to run it along with the main wiring harness in the
forward systems holes.
In the right wing, there is no conflict, the coax
cable would just cross over the main wiring harness
between the sixth and seventh ribs.
What have others with Garmin avionics and a wingtip
nav antenna done?
I used some PEX to make a conduit for both wings: It
came in handy running cable for Archer wingtip
antenna as well as heavy 14Ga wire to pitot heat.
Plus a bit of future flexibility.
RE: Flutter Testing (Not RV but eye opening)
"...Fourth point, reflected in the FARs is if you
have a trim tab on a control surface, the Vne series

connection will not contribute to flutter..."
would HIGHLY discourage this kind of test...from
I had a C-421 that had a "failure" of the bolt
connecting the right elevator trim tab to it's
linkage. (The failure was due to negligence of the
company that did the annul inspection.) The failure
occurred at 16,000 feet climbing to a cruise
altitude, at a speed SIGNIFICANTLY less than Vne.
When the bolt came out of the linkage, the right
elevator began to flutter in a divergent mode,
resulting in an airplane that was nearly
uncontrollable. Luckily, the two elevator torque
tubes are joined in the middle with bolts through a
flange. These bolts sheared, separating the
elevators. It also stopped the flutter.
This happened in the space of about 5 seconds.
The aircraft was flown to a successful landing with
one elevator in control and the other in
trail...lucky to say the least.
Flutter is nothing to mess around with, and it
doesn't matter if you THINK you are the ace of the

RV-12iS Service Bulletin - SB 19-08-06 - AV-60000 and AV-60009
"Van's Aircraft has published a new Service Bulletin (SB
19-08-06) that describes steps to be taken on certain
RV-12iS aircraft, in order to capture detailed photographs
of two electronic components and then send the photos to
Van's for review.
In limited cases, solder on AV-60000 and AV-60009
electronics modules may not have been heated sufficiently to
ensure a strong enough solder joint. In those cases, there
exists the potential for intermittent electronic issues.
Photographic examination of the components will allow
Van's staff to visually determine whether or not the
module's solder joints are properly formed and acceptable.
In the event the soldering of a module in the field is
determined to be insufficient, the module will need to be
shipped to Van's for service. In this case, Van's will pay
the shipping costs to return the defective module to Van's,
and to deliver the repaired/replacement module to the
When taking the photographs, please ensure that 1) plenty of
light illuminates the subject - a flashlight or similar
source may be used, and that 2) the photos are close-in,
sharp and taken in high resolution. Most modern smartphones
should be able to produce acceptable images.
Note that Van's has identified and confirmed the root cause
of this issue and has made changes to its manufacturing
processes as a result."

How to get plane into hangar up ramp slope
I just got a hangar for my RV-12 (a brag-worthy
accomplishment in Southern California). I love having the
plane in a hangar. But I have to muscle the plane up a
slight incline to get it inside. I can do it using a tow bar
to push and steer, but it's very tough. So I am looking for
some electric power assistance.
I can install a winch (with a remote control on/off switch)
to pull the plane in. But I wonder whether I'd damage the
plane if I attach the winch cable to the tail tie-down ring.
I ask about using a winch because it would be dramatically
less expensive than an electric airplane tug. Even for a
plane as light as an RV-12, the least expensive tug I've
found is $1,500.
Information about your experience, and your opinions, will
be welcomed with thanks.

This is what I have come up with. Apart from the general
layout, some of the specific questions I still have are:
Should I put the GAD 29 on the Avionics bus, or the Main
Bus? It is only needed for the Avionics (GNX 375 and GNC
255), but other examples placed it on the Main bus...
I have a breaker and a switch for the GAP 26 Pitot Heat. Any
reason not to just use a Switch Breaker?

Long Term Review of the CQ1 Headset + Comparisons to the competition
About a year ago, I wrote a rave review about the
CQ1 Headset by Card Machine Works. I'm likely
biased in my opinion, but such bias is hard won and
isn't always a bad thing. I've known Scott and Tanya
for years. I think very highly of them. I've met few
individuals with their combination of integrity,
drive, intelligence, and capability. To find a pair
of them marching forward together in life is a true
gift. Enough of the disclaimer, on to the review.

$13 at Lowes and I had a new, longer hose for my

Real World Numbers, Am I Missing Something? ...OneTwoTree (9/9A)
Let me start by saying long time lurker first
time post. My mission is to travel and get my IFR
ticket (for safety not for necessity). So naturally
the 9 comes into picture. The 14 is a bit too rich
for my blood. I want to be done at 80K with an IFR
machine not 100K. The 9 is attractive, but I'm still
dumbfounded that it only has a 36 gal capacity.
Imagine my excitement when I find the Hotel Whiskey
extended tanks. Then I ran the numbers:
empty weight 1050 (middle of average according to
fuel weight 216 = 1266
A/C weight 48 = 1314 (Not negotiable according to
HW ER Tanks 10 = 1324
ER fuel weight 60 = 1384
pilot weight 200 = 1584
co-pilot weight 150 = 1734
This leaves 16 pounds for bags ......... not good
When I run the same numbers for the 7 I get:
empty weight 1100 (middle of average according to
fuel weight 252 = 1362
A/C weight 48 = 1410 (Not negotiable according to
HW ER Tanks not needed
ER fuel weight not installed
pilot weight 200 = 1610
co-pilot weight 150 = 1760
40 pounds of bags.
You can't have it all. I know that. I could have the
ER tanks installed and if they are unfilled I've
added 60 pounds that I could carry (76 total for

don't have to move stuff around and you don't have
to maintain a long air hose.

and Microballon Practice Begins ...David Paule RV-3B
It's been a while since I worked with epoxy and
microballoons and foam, and since I had enough stuff
to work with, I decided to make a practice kit.
Starting at the far back, is a roll of fiberglass
cloth which I didn't use today. Just in front of
that is a bag of microballoons, left over from the
sailboat I had the first decade of this century.
Then the tall can is some epoxy resin, Rhino or
Jeffco 1307 LV, and to its right is a quart of the
associated medium hardener. At the right of the
hardener is my mixing cup and the two pieces of
scrap foam that I glued together with the
microballoon and epoxy mix.
In the foreground we can see the gram scale and the
syringes I used to meter out the resin and hardener.
This is the first time I'd used this resin system.
Steve Smith recommended it, and so far, based on
this one trial, I like it. It's available from
Aircraft Spruce. Previously I'd mostly used the West
The gram scale measures and reads down to 1/100 of a
gram. The closest I could get to the goal weight was
about .03 grams and that took some doing. Frankly, I
don't think that precision was necessary, but that's
a guess; I don't really know.
The mix had the consistency of peanut butter. I
could have made it drier and if I repeat the
experiment, I probably will.
I'll let this cure completely and then carve and
shape it and sand it to see how it feels.

fix RV-6A that needs large changes in elevator trim ...mtnflyr
I bought a 6A some time ago and need some help
understanding what changes I can make to it to
reduce the need for large changes in elevator trim.
On final, I can't trim out the stick force with full
nose-up trim. It's manageable, but I like to trim to
a stable hands-off state and I can't do that today.
For takeoff, flaps up, the airplane rotates nicely
with a fair amount of nose-up trim, and I have to
trim aggressively down as the airplane accelerates.
This isn't a huge deal for a normal takeoff but
makes the airplane a handful on a go-around.
The trim movements I need to go from 80 mph to 120
mph are significant - much more than I'd like to
have to do.
What should I check? CG comes to mind - I'm guessing
that the airplane has a CG that is further forward
than optimum. Would forward CG cause the need to
trim more than a properly balanced aircraft? I don't
want to start messing with stuff without
understanding the aerodynamics causing the behavior

out about the 6xx Xi series....

I bought my RV-12 early SN (120058) from the

Center Section and Fuel Tank were not completed. I
flew for a year before completing these two service

RV smile wasn't wearing off. So, in my case the
Center Section Modification was completed at 205TT.
No cracks were found during the work. This area is
given extra care for visual inspection during Annual

Product Announcement: GTN 650Xi & GTN 750Xi Series IFR Navigators (1/6/2020)
We are excited to announce our new GTN 650Xi and
GTN 750Xi as the latest addition to the Garmin
product line of touchscreen IFR navigators.
Designed as a direct slide-in upgrade to the
previous generation GTN 650/750, pilots can preserve
their panel and modernize the cockpit with the new
GTN 650Xi and GTN 750Xi. Available in five different
versions, the GTN Xi series matches its predecessor
in providing options with or without COMM or NAV
radios. The all-in-one GTN 750Xi GPS/NAV/COMM boasts
a large feature-rich multifunction display and can
integrate with new or existing remote-mount
equipment such as a transponder or audio panel.
Dual-core processors and modern hardware also
prepare the GTN Xi series for advanced capabilities
in the future. The GTN 650Xi and GTN 750Xi have
received FAA approval and are available immediately
for fixed-wing single-engine and multi-engine
piston, turbine and experimental aircraft.
Sensor Probe ...how Sam B. did it.
Very easy to make a probe with 1/4" copper or
aluminum tubing. Here is a pitot static probe I made
for one of my aircraft:
To make an AOA probe from this basic design,
eliminate the small holes and plug in the static
probe and bend the lower ram probe down at a 45*
angle. The top tube will now be the high pressure
port and the bent, lower probe the low pressure
port. You may need to slightly bend the lower tube
via flight test to get your LRI to indicate properly
at stall AOA. The design of this probe can be
tweaked to make it look better....make the tubes
closer together...fill in the gap with
The indicator referenced in the above post is the
same one used in the LRI system and works as well as
the Lift Reserve Indicator I've been flying for
nearly 20 years in my RV-6. The LRI is my primary
indicator for max performance takeoffs and landings.

a Few Weight Saving Ideas ...Tdeman
I've been trying to save weight wherever possible
on my RV-6 build and will share a few of the things
I did. Now, I have a running bet with a few guys on
what my empty weight will be, so you'll notice some
of these get increasingly maniacal. I'll spare you
the full on weight-psycho stuff until I weigh in and
either have to use it or not.
A lot of people mention the wood prop saving 25-30
lbs, but then go and put a 18lb crush plate on the
nose for CG reasons With that in mind, I focused my
weight savings at the tail. Ideally allowing me to
run a composite prop without a weight up front.
Starting at the tail:
-Using the classic RV-6 VS and rudder (no
counterbalance) (sorry 7/8/9 builders, not an
-Built a new set of .016 elevator skins using RV-7
counter balance arms which are longer, and position
the CW horizontally, thus requiring less
counterweight. (The combination of elevator
counterweight and skins will be nearly a 2lb
-Turned a titanium tailspring on the lathe (1lb
-Planning to do a billet tailwheel fork and Ti axle.
-Scallop the mating flange of the fairings and pop
rivet instead of screw on.
-MS-21042 instead of AN-365's
-Round and taper those corners on your 1/8" angles
and straps in the tail.
I'm hoping that by pulling 4-5lbs out of the
aft-most point on the aircraft, I'm able to run a
ground-adjustable composite prop without any extra
weight up front (saving another 10-15lbs). Engine is
a carb'd O-320.
Then of course are all the easy ones throughout the
rest of the aircraft:
-Build a taildragger
-MS-21042's instead of AN-365's
-Single EFIS Glass Panel with LRU's mounted as close
to power/data hub as possible.
-Careful and efficient wiring throughout (See
AC-43.13B for calcs and help on minimizing wire
-Fuses instead of circuit breakers
-Single (or double) set of seat back hinges. Single
seat back angle per side on the cross bar (speaking
of which, lighten that piece of angle up!)
-Lithium battery (Easy 10lb saved compared to an
Odyssey, 20lb lighter than a concord).
-Aluminum battery box (see RV-14 battery box if
using an odyssey).
-Aluminum hard lines instead of rubber hose wherever
-Single set of brakes. (And throw those master
cylinders in the lathe or mill to get rid of all the
extruded material between the ports.)
Sometimes I ask myself if it's worth it... However,
flying a heavy and lightweight RV back to back often
reminds me that it is not in vain.

RV Activity ...DanH
evening in Alabama, so I got in some formation
practice. Quick over the shoulder shot from Stan Tew,
passenger in Kirk Harrell's Mustang II:
I noticed the brake pads getting a little thin
during the condition inspection (450 hours), 2nd
flight after the condition inspection my main
alternator voltage was venturing above 15 volts. She
needed a little more love.

Time Post and Buyer
Hello new friends.
I am about to complete my private pilot certificate.
I'm also about to graduate veterinary school and am
heavily considering taking a job around 600 miles
from home. They want me to work part of the week,
and I'm considering going back home and
working/being with family the remainder of the week.
I wouldn't do this every week, just kind of depends
on the weather.
Because of this, I'm heavily considering buying a
plane. My mission would be 600 mile cross countries
by myself. Want something quick, fuel efficient, and
a good plane for IFR conditions (plan to get
instrument certificate soon after private). Right
now considering 6, 7, or 9's. Prefer the side by
side seating, prefer a tricycle gear but I'm willing
to get tail wheel endorsement for the right
So my main question, how difficult would it be to
overhaul the panel on some of these older rv-6's or
cheaper built rv-9's? Adding auto-pilot? I'm pretty
handy for the most part, decent on electronics, but
I'm pretty good at problem solving and finding a way
to get something done.
Any input on any of this is greatly appreciated.

engine replacement ...pros and cons
My RV-6 is on about 1830 hours. I'll have an
annual condition inspection in October, then I think
there'll be engine work in 2021.
Current engine is a carburetted O-320-D2A with a
Sensenich fixed-pitch cruise prop.
I didn't build the aircraft.
The current fuel system has plumbing feeding an
Andair valve supplying the suction side of a Facet
fuel pump on the inside wall of the fuselage between
the pilot seat and the rudder pedals, with the pump
discharge feeding a gascolator on the engine side of
the firewall, which in turn runs to the

It's still more than a year and a half away, but
planning is good, and the direction I'm tending
towards now is to take the O-320-D2A off and replace
it with some variant of an IO-360, probably also
with a fixed-pitch prop.
The change from carburettor to fuel injection is
going to involve fuel system modifications: I'm
anticipating that the Facet pump will end up in the
trash, with a new high pressure fuel pump and new
I'm sure someone has gone down the path of carb to
fuel injection before, and if anyone has advice I'd
love to hear about it.
Are folks generally keeping high-pressure fuel out
of the cockpit, so where's the right spot for the
electric pump? Is the gascolator necessary?
Considerations for routing fuel lines to avoid vapor
lock? How are fuel systems handled in modern
certified aircraft? Anything else I'm not thinking

mistake on RV-14A Rudder Spar Reinforcement Plates ...jdog0411
Wanted to get the forum's opinion on the
following...I've sent this to Vans technical support
for their opinion as well, but in the meantime
thought I would ask here also.
I recently completed riveting the Rudder Spar
Reinforcement Plates onto the rudder spar for my
RV-14A. I riveted them to the spar with the shop
head on the spar side of the spar, when in
retrospect I probably should have riveted them with
the shop head on the plate side of the spar since
that is the thicker material. The plans didn't
specify, so I didn't think it would matter one way
or the other.
Hartzell Engine Technologies Press Release
FOR IMMEDIATE DISTRIBUTION
HARTZELL ENGINE TECHNOLOGIES ANNOUNCES IT IS NOW THE
EXCLUSIVE SUPPLIER OF PLANE-POWER ALTERNATOR
ASSEMBLIES FOR LYCOMING FACTORY OVERHAULED AND
Under the partnership agreement with Lycoming,
beginning January 06, 2020, Lycoming factory
overhauled and rebuilt engines will no longer be
shipped to the end-customer with alternators or
accessories. Going forward, customers will now
purchase Plane-Power components directly from
Hartzell Engine Technologies.
Montgomery, AL (January 06, 2020) --Representatives
of Hartzell Engine Technologies (HET) announced
today that the company has partnered with Lycoming
to now be the exclusive direct-to-customer provider
of Plane-Power alternators and alternator assemblies
for a factory overhauled and rebuilt engine.
"As the manufacturer of Plane-Power alternators and
components, we have been providing alternators and
accessories to Lycoming for all of their factory
overhauled and rebuilt engines for a long time,"
stated Keith Bagley, President, Hartzell Engine
Technologies. "The primary reason that we are now
transitioning to the direct-to-customer supplier for
these components, including full alternator
assemblies and pullies, is to provide much better
delivery and direct factory support to the
"By eliminating the added steps of shipping to
Lycoming and then to the customer, we can respond to
the customer's needs, and correct any problems,
faster and more efficiently," he said. "In addition,
should an owner/operator want to upgrade their
Plane-Power alternator, the factory-direct order
model will make that process a lot easier."
Bagley also explained that while customers will now
buy their Plane-Power alternators and assemblies
directly from Hartzell Engine Technologies in the
majority of cases, there are some unique situations
where, depending on engine model and configuration,
alternator brackets and belts will continue to be
installed and/or supplied with some Lycoming factory
overhauled and rebuilt engines.
Because the transition is happening very quickly,
Bagley provided additional details that will help
clarify some key points:
- Customers who take delivery of their Lycoming
factory overhauled or rebuilt engines, prior to
January 06, 2020, which include Lycoming
factory-supplied alternators are still required to
return an alternator with their exchange core
- Customers who order Lycoming factory overhauled or
rebuilt engines on or after January 06, 2020, may
keep their existing alternators or replace them at
their discretion based on either the condition of
the alternator or Instructions for Continued
Airworthiness (ICA) where applicable.
- Lycoming Service Instruction No. 1154,
FAA-Approved Starters and Alternators, will continue
to be an active document.
- The next revision of Lycoming Service Instruction
No. 1154, (S.I.1154W) will provide additional HET
part numbers for alternators and alternator
assemblies available directly from Hartzell Engine
"The end-goal of this process is to ensure that
aircraft owner/operators and their maintenance
providers will enjoy a greatly improve overall
customer experience when ordering and installing our
Plane-Power alternators and components," Bagley
said. "In addition, should they ever experience an
issue, having direct contact with our technical
experts here at the factory will make that whole
process easier and more efficient."

Our formation group has established a bit of a tradition
over the last few years, of meeting up late in the morning
on January 1st and flying somewhere "interesting," usually
for a spot of lunch.
This year was slightly different: Glenn volunteered to lead,
and planned to take a 6-ship around Sydney Harbour.
It started with a formation briefing, six pilots and six
passengers. Half a dozen RVs departing runway 11C at
Bankstown in two elements of three, with yours truly leading
the second element.

Used about 1qt in that 30 hours with level kept at 6-6.5 qts.

aircraft sat for sale with limited flying last year. Jug was

I flew aircraft for 45 mins and drained oil. This was an
easier than expected, but a little messy pulling screen.
Here's what I observed...
Oil was remarkibly clean looking for 30 hours. With the
limited burn I would guess this means the upper end is
runing tight with limited blow-by.
Screen caught a small amount of carbon and what seemed to
been some old rubber gasket/seal material. Total...it was an
immeasurable amount with no metal
Oil filter - Filter media inspected and run over with strong
magnet, no metal found
Oil filter media washed with mineral spirts and fluid was
strained in coffee filter, no metal, and only few small
specks of carbon found
Strong magnet was placed in jar while washing filter media
to pick up anything ferrous. Only a very small amount of
ferrous material was found (see picture).
The ferrous material collected by the magnet was very
fine...like dust, but there was a couple small flecks of
metal < 0.5 mm wide and very thin.

RV-6 Rebuild Project Update ...jamlip
Still going with this thing...
Removed and de-sloshed the fuel tanks. They've been built
oversize to 28 gallons each side, and when you stand them on
their end, they're about as tall as me. It took me about ten
hours per tank, and I used $150 of MEK.
Today I fitted new wing spar cover panels. The aircraft
didn't come with any, depite there being evidence that there
were once some fitted. Took ages - really annoying. At the
same time, I made a centre section for the floor, since I've
done-away with the standard battery box.
Initial Contact ...Phil
I've been lurking on these forums for a number of years now
and have gathered a ton of knowledge from all of you. There
is a lot to absorb and I can say that this forum was one of
the reasons I finally decided to start my RV-7 build.
I ordered and received my empennage kit back in the spring
of 2019 and have been (very) slowly progressing on the
build. I started with the wing and toolbox practice kits and
learned a lot working through those "tutorials". Currently
I'm working through the horizontal stabilizer, which is
teaching me even more!
Being up here in the Great White North, the colder
temperature in the shop in these winter months slows
progress a bit. Working with what feels like (and probably
is!) frozen aluminum requires a few more breaks back in the
house to warm up!
Thanks again to all for sharing your experiences on the
forum, it is an invaluable resource for RV builders!
Anyhow, just wanted to give a quick intro and I know I will
be posting with more questions during the course of the
Mystery Airstrip ...Vlad
Is this a reasonable way to wire up my landing/taxi/wigwag lights?
The struggle to nail down my electrical system continues;
let's talk about how I want to do my landing and taxi
The light units will be Flyleds combo units, one in each
leading edge. For those unfamiliar, each unit has four
projectors, one of which can be separately switched and
aimed to act as a taxi light. Since I'm building a TW
aircraft, I intend to use that functionality. I also want to
have wigwag functionality for these lights, and I intend to
use the Flyleds wigwag module to do this. What I want is to
have two switches: one three-way switch with OFF/TAXI/BOTH
positions, and one two-way switch to enable wig-wag.
The first source of interest here is that the wigwag
module only has single power outputs, one for the right wing
and one for the left. I want the wig-wag function to power
both the landing and taxi units, which means at that point
the landing and taxi circuits must be tied together - which
means I lose the ability to apply power only to one of those
circuits when I want the TAXI/BOTH switch on.
The second is sort of the other side of that coin; if I want
to have a single switch for OFF/TAXI/BOTH, then the power
outputs there for landing and taxi are electrically tied
together, which prevents the wigwag module from being able
to only apply power to one wing.
Basically, the issue is that every circuit can backfeed
every other one.
Now, I'm a bit naive when it comes to electronics, but
offhand this seems like a problem that can be solved with
diodes - strategically placed diodes prevent any leg of the
circuit from backfeeding any other one. The only practical
problem I see is that I'll incur a voltage drop at all times
to these circuits. But some annoying part of my brain wants
to think that this isn't the way this should be done.
So what I'm asking is: is this a reasonable approach, or
Initial Panel Ideas ...kentlik
I was exploring new to me vicinities. Looking for a good ice
I modified my air intake. Ok, so it's not earth shattering, or even sexy
in any way, but I've been slowly modifying my intake to get the best
performance, which I measure by air intake temperature and by manifold pressure.
What I did this weekend was put a scoop (cut and folded 0.032" scrap I had on
hand) over my intake. No, it's not as aerodynamic as it could be or even
aesthetically pleasing, but gets the job done. The idea was to validate for
myself the difference between a NACA duct and scoop. I can tell you the scoop
makes a huge difference.
Still chipping away at the cowling and baffles.
Started trimming baffles; getting closer... but I
just don't see how RV-8 builders manage to get their
oil cooler to fit in the stock position. If any -8
builders want to share photos of their finished
baffles on the left side by the oil cooler, or if
there are any -8 builders within 100 miles of
Clarkston, MI that would be willing to allow me to
inspect their cowlings and baffles, I'd be very
grateful. (Hopefully Terry Lutz is reading this;
then we'd finally get a chance to meet up! )

The sun was already high up and
shining brightly when I finally decided to get out
of bed. It was the year 2020, and the percussion of
mortars from the night before still punctured my
memory like the blind bursting of complete darkness,
of a part of my life that had been blown away,
hopelessly and irrevocably, as into a void. There
was that hollowness in the gut that often precedes a
flight where uncertainty must have its way no matter
how well-planned the flight is. The mortars
reverberated in my brain as if exploding on some
great battlefield where the world itself was
tenuously hinged, and as I packed my gear and headed
out the door, my dog was whining because she had to
stay home without me.
I was airborne out of Merced (MCE) less than an hour
later heading south at 11,500 feet. The Sierra
Nevada range rose snow-capped to the port side, and
further south, a portion of the San Joaquin Valley
lay buried under a pale scab of fog.
RV8 going IFR ...Jimmie Kemp
Q: I'm installing a pair of garmin G5s and
a GNX 375 in my RV8. I would like some advice on
where to mount the garmin antenna and magnetometer.
For the Magnetometer, I went with the end of the
left wing. I've got a GRT, so not 100% sure that
Garmin wants theirs to be as far away from ferrous
metal like GRT, but physics are physics.
The magnetometer is attached with double sided tape
inside the 2nd hole in this picture.
The GMU 11 is an extremely sensitive magnetic
sensor, so it is important to choose a suitable
installation location, and properly align the unit
when installing it. This table outlines the
recommended separation from various types of
You can basically use this as a way to prioritize
what is most important to avoid. For a wing mounted
unit, it will be important that any lights installed
in the wing are not grounded to the air frame out in
the wing. You will want to run a dedicated ground
return back to the fuselage. Also any electrical
conductor running through the wing, should be
twisted, shielded, and routed as far away from the
GMU 11 and its wiring harness as feasibly possible.
Feel free to reach out to us directly if you have
any other questions that come up.

Last Flight of 2019 (RV-14) ...Georges Grenet pics/vids
Spoiled Rotten ...Robert M
While in the midst of helping my
wife get some "Pinch Hitter" training at a local
airport, I let MY BFR lapse. So, I set up an
appointment with one of the local flight school
instructors to renew. Went through the usual "ground
school" chat and headed for the C-172. Again, the
usual pre-flight. Taxied out, rolled onto the runway
and started the takeoff roll. Oh my gosh, was I
dragging the fuel truck? Was the engine not
delivering full power? I was concerned we weren't
gonna be able to even rotate the nose wheel before
running out of runway.
AND......during the initial ground roll, I told the
instructor; "in my RV, we'd be off the ground by
now". And when I got the 55kts to rotate the nose
wheel, I told him; "in the RV, we'd be above pattern
altitude by now". Then there was the, (what felt
like), endless climb to the maneuvering altitude of
3,000 ft. Jeez, I don't remember it taking that long
back when I rented 172's.
Please understand, I wasn't trying to brag although
it sure sounded that way. No..... it was more like I
was complaining. I have been so spoiled with how
quickly the RV-9 can get up on the mains, rotate for
takeoff and climb to altitude. Spoiled Rotten!
In retrospect, I can see more clearly that things
happen SO much faster in the RV and a greater need
for due diligence is required for all aspects of

Thank you all ...Tom Swearengen of TS Flightlines, LLC
I just wanted to take a minute to thank all the VAF
family for the outpouring of support shown after Suzanne's
passing. It was really unbelievable.
Its been a couple of weeks now, and yes its getting easier.
I'm doing more cooking now, ( well ok Me and Zaxby's,
Subway, etc) but as some of you have noticed, I've been
working alot more. Yes it helps! My role has actually
changed alittle from doing most of the hose assembly
building to more of a concept/creation thing. I want to give
a selfish plug to my business partner Steve Tschurwald of
Aircraft Specialty, and our joint company AS Flightlines.
Without him, alot of things that transpired the past 2 years
would not have been possible.
When we came up with the idea of merging some parts of our 2
companies to better help all of you, neither one of us
dreamed --or had a nightmare, depending on your position,
that the merger concept would actually allow me to spend a
bunch of time with Suzanne, and get her the best medical
care available. If I was doing everything like I was at one
point, she would probably have suffered MUCH more than she
did, and at the same time, all of you clients possibly would
have too. So, Steve---a toast to you my friend.
When bad things happen we sometimes dont have a clue who is
affected. Suzanne didnt know alot of you, or had any actual
contact with you. But she knew of you, and I can speak for
her in saying that she appreciates the outpouring of love an
support you have all shown. Its made both her and my
transition easier. House is still quiet, but its feeling
warmer, and I think its because shes near.
OK----so 2019 is leaving us, and 2020 is tonite. Steve and I
have several new things that we'll be releasing. A few of
which have already gotten out there. I wont go through them
all, but some are already on the joint website
asflightlines.com. LOL---my tsflightlines.com website is so
outdated, and gee I'm not a computer guy so its just kind of
sitting there. So most of the newer things ar on the AS
Flightlines site. A couple of possibly relevant
things-----I'm going to finish my 7A---Sue said she'd kick
my butt if I didnt. Gee that means I have to straight out
the shop, but it also creates more room. The intent here is
to build several full scale mockups so we can do more R&D
inhouse to speed things up some. These might include from
baggage bulkhead to engine mount the cabins of 7A/9A, 10,
14A, and several other aircraft. In addition, due to popular
demand, engine and accessory mockups for IO360, IO390, and
IO540. Lots of different sump/servo combinations that you
just cant plan for unless you have an actual engine sitting
there equipped with the accessories youre trying to build
data for. So, the idea is to have some of this here, so we
can bolt on a sump and servo and get actual data on
things----to make your lives easier. And at the same time,
actually install the engine on the mockup and get real live
dimensional data. Sounds crazy, and we probably could do it
in Solidworks, but need the data to begin with. And---well
its experimental, so everyone has a little different take on
how they want their plane to be.
So we may be asking the VAF group if you have parts you want
to sell/donate etc. Anyone priced a Superior cold sump
lately? Or an Avstar servo---see it adds up FAST. All of
this in due time---but its something that we think will be a
huge benefit to all of you.
So--2020 will be here shortly---it will start off sad
because my beautiful Suzanne is in heaven and not here, but
knowing she beat cancer, and is better now gives me alot of
peace. With the things we have in the works and planned, we
will be busy, and that helps too. Several NEW projects are
in concept stage now, and we'll be able to work on them.
One last note--Many of you over the years have asked about
us doing a booth at AirVenture. Due to expenses, and time
away from the shops we havent done one. But---with the new
things we will be releasing, and some skunk works things
too, maybe its time to do a booth. Those of you that do
exhibit there know the money part, the time involved, and
the total effort to make it happen. Some have said its a
loosing proposition. Maybe so, but we think its a great way
to get the word out, and let you see whats happening. Might
More later on that--
Again thanks to all of you my friends, for all the kind
thoughts and expressions of support over this difficult time

Panel Layout Feedback ...N546RV
OK folks, I think I've finally firmed up this panel
design to the point where I want to get some feedback.
Intended use case will be primarily day/night VFR. The
aircraft will be IFR capable, even though the pilot probably
won't be for another couple years.
Broad strokes of the setup are pretty self-explanatory: two
10" Skyview HDX displays, plus a Garmin GPS175 to fulfill
the TSO'd GPS role. After much thought, I decided against a
second COM radio; it's not depicted on this image, but there
will be provision for connecting a handheld transceiver into
the ship's antenna, and that'll be my backup COM solution.
Other redundancy will be provided by the Skyview backup
batteries and dual ADAHRS. Also seen here is a controller
for the SDS CPI2 ignition, which will also be equipped with
its own backup battery.

Leaking Fuel Tank Rivet ...f14av8r
Okay, so I've tried all the tricks
to get this rivet to quit leaking. No amount of
pressurized cattle syringe injection of any type of
sealant has worked. They slowed the leak quite a bit
but have not stopped it completely. So, I'm ready to
take the plunge, drill this sucker out and replace
it with a new, sealant coated rivet so I can get the
leak stopped and the paint back in order!
The plans call for a AN470AD4-4 rivet. Obviously,
I'll need a blind countersunk rivet for the
replacement. To save me having to learn all about
Cherry Max rivets again, would one of you rivet
wizards tell me what I should use here please?
