I lumped some time together for today. The last several days I have been preping the ribs and floor parts whenever I had time. Today I installed the 915 outer ribs. Dimple the bottom skin and rivet. Riveted to the rear bulkhead. Spent some time going over everything to make sure I was ready. Details, details. The seat belt anchor bolts didn't all look quite right, checked the plans and found there are two different sizes used. The outer bolts are -6 instead of -5. Get the correct bolts and they now have the correct 2 threads sticking up past the nut. Torque and paint lock, done!
Installed the floor panels. I tried to complete as much as I could with the floors. Installed the seatbelt crotch parts with nutplates. Dimple the baggage floors, clean the edges, and prime. It all fit together very nicely and really makes the center section very stiff.
