Started installing the 916 ribs to the 904 aft bulkhead. Installed the bolts in all 8 ribs, set the two edge rivets that can be reached with the squeezer, and then the flush rivets at the top flange. Used the hand squeezer. Need to start using the pneumatic one, but I didn't want to use it on these somewhat tricky rivets.
Post Edit: Before riveting the ribs on, there are a few more things that are nice to do. First, start thinking about wiring. Look at all the builders sites to see how they ran their wiring. It can be a challenge to get all the necessary wires past the center section to the aft of the airplane. You might want to cut a few more holes for snap bushings. I decided to add nutplates on the center seat and baggage ribs to hold adel clamps that will secure wiring bundles. It's a lot easier to do it before the ribs are fixed in place.
1st rivets in 3 weeks. 9970 and counting.
