Default Need Advice on Canopy latch adjustement

Our flying club purchased an RV12 from the builder. We LOVE the plane but our mechanic is new to Vans/Rotax/Dynon, and we are going through a learning curve. Most recently, our canopy seems to have shifted slightly. When we bought it, it worked fine. But now, to latch or unlatch you have to pull - with a lot of force - towards the back of the plane and down. It's almost impossible to do while buckled in - so obviously this is a safety issue.

Any advice on how to adjust is appreciated.

The simplest thing to check is for shims under the white latch block on the roll bar. If there are any, try removing one to give more clearance with the latch. Itís secured with three screws.

Thanks Bob. That will help with the vertical - what about the front-to-back? You have to pull the whole canopy towards the back of the airplane for the handle to clear the catch.

Check the pivot points at the forward end of the canopy.
Are they too loose?

Check with Van's on Monday and buy a KAI on a memory stick, on how to adjust. Basically they are blue prints on the build. About $10, last I checked. Is this E-LSA or S-LSA ?

It's been many years since i built the 12 but I remember it took a lot of fiddling with the UHMW blocks and the latch itself to get it to operate properly.

Don't be afraid to file parts down as necessary to get the latch to work properly. Just do it a little bit at a time.

What is the "proper" tightness? Is it listed somewhere or is it pilot preference?
