Are VGs a "major change?"

[2theskyy]

I’ll put it on the same stc as for lcp cracked holes.
But seriously.
Experimental or certified mods are always good to test flight. Paperwork first then “phase 1” to run it through the ringer in flight tests. You always want to know the envelope you are wanting to stay within.

To be clear about this, my intent is to place it back into phase 1 and do extensive testing. My question about the major change is more of a legality question, the answer to which drives how much I need to get the FSDO involved. Obviously I’d like to keep that to a minimum but if only I’m on solid legal ground to do so.

More specifically my ops lims require me to notify the FSDO of my plans and get their concurrence on the new phase 1 area- if it is a “major change.” I had a busy and delay-filled day at work so I was not able to reach out to the FSDO. I’ll try again tomorrow.

If your op lims require FSDO notification, then that's what you do.

Operating Limitations rule!

Fully understood on that point. I’m just trying to tease out whether or not this particular modification qualifies. I have a call into the Milwaukee FSDO and I’ll report back here on their answer.

In the mean time, what say you, Mel? Are VGs a “major change?

Yes, as said before, VGs may (Probably) change the flight characteristics of your aircraft, so they would qualify as a "Major Change".
