Today I finished installing the access panel, installed an adel clamp for the pitot lines, and riveted on the end caps for the gap seals.
The access panel was straightforward; I riveted on the nutplates, then riveted it to the wing. I then spent time getting the panel itself to fit, I had to file about 1/32 off one edge. Then I screwed it on. I ran into a problem when the last screw’s head sheered off. I need to pick up an easy-out to remove this and try again. It sure why it sheered off, I don’t think I was using too much torque, just a handheld screw driver.

Those Adel or is it Axel clamps are great I use them a lot on the boat to secure pipes and wiring
