Today I finished riveting the right lower longeron to the floor and riveted the left to the floor. I had to remove the outer most bolts on the front and back walls of the landing gear boxes to be able to get 'in there' with the rivet gun properly.
I riveted the nutplaes to the mid cabin braces and the center section assembly.
I removed the nuts from the bottom bolts in the seat ramp supports (F-814E), pushing the bolt into the center section just enough to rivet the inboard seat assemblies (F-814A-L1 and R1) to the supports.
I clecoed the seat rib subassembly to the center section subassembly.allowing me to rivet the F-814E's and F-814A's L+R together. I then clecoed the outboard aft and forward seat ribs to the center section from the inside as instructed. Replacing the washers and nuts, tightened to finger tight, on the bolts that go through rear half of the center section and the seat ramp supports.
Left lower longeron riveted.
center section clecoed to the forward floor, cabin braces clecoed.
Cabin braces have been riveted to the center section.
