I noticed 3/16-4/16" of twist in my left RV-9A flap that is almost finished (TE to be riveted still). Is this considered acceptable or should I try and fix it? The plan would be to drill out the lower skin to spar rivets, flatten the flap, and reset them. I am not too keen on this as I may enlarge the holes a little from drilling out. Some are already oversized a little from the countersinking. Thoughts?
Thanks.
Thanks.
