In preparation for riveting on the wing bottom skins, I wanted to take care of a few last items inside the wings. First up, I installed the remaining fuel tank z-bracket bolts and torqued/sealed them. Afterward, I installed the remaining screws that attach the tank (only on the bottom of each wing since that’s all I could reach). I also cleaned out each bay and stripped the plastic from the insides of the wing skins.
This bracket ties the pitot tube mount to the adjacent rib. I primed it and riveted it to the rib with some AN470 AD3-4 rivets.
Finally, I installed the countersunk nutplates on the top side of each wing aft of the spar. I’ll do the bottom side of the wing aft of the spar after the bottom skins are riveted on. The nutplates around the inboard edge of the tank will have to wait until I can remove the wings from the stand.
