Stjohn's RV-7

1 hours.
I put the nutplates on the fuel select bracket and cover box. I totally brain-farted too. I forgot how you’re supposed to handle nutplates on thin-skinned material. I made doublers for the flanges on the cover box, countersunk those, then dimpled the holes in the cover box and used flush rivets. it works just fine, but I have to go over the handbook and find out if it’s cool to put nutplates directly on the backside of dimpled holes. I’m pretty sure it is, but I want to know, not guess.
