Finished riveting both outboard seat rib assemblies to aft center bulkhead.
Riveted rear seat subassemblies and dimpled 3/32" holes in web of F-1015A and F-1018 ribs. Clecoed outboard seat subassemblies to rear spar bulkhead and riveted. Clecoed and riveted F-1005C bulkhead side channels to rear spar bulkhead. Clecoed and riveted F-1018 outboard seat ribs and F-1015A footwell ribs. And then my day went bad. Somehow missed the three bottom outboard seat rib rivets and thought I had put in rivets ahead of plans that were to go to left rear seat assembly. Long story short, removed, installed and then removed 30 rivets between the two sides. Finally got my head wrapped around how this is to go together, but in the process 7 holes were oblonged and up drilled to 5/32" to make concentric holes. I am now very happy with the quality of the final outcome. F-1015A and F-1018 still to be reinstalled.
Got help riveting 5 of the 10 remaining rear seat ribs.
