Over the last three days I finished a lot of prep work on the left tank in preparation for attaching the baffle. Got the outboard rib sealed and riveted, attached and wired the sender plates, and permanently installed the flop tube into the inboard leading edge.

I also had to find a way to secure the hinge pin that holds the trap door in place on the second inboard rib. The second rib and trapdoor form a sort of header tank that retains fuel when doing aerobatics. I can foresee a need to remove the hinge and door at some point, so I wanted to make a clip that I could reach just by removing the access plate. The little clip has a small hole for safety-wiring the hinge pin, there’s a little proseal on there as well.
