I was out of town the first half of the week, so I didn't get anything done until today.
I had the realization that there was no way for me to countersink and set the rivet for the two outboard seat ribs that attach to thw carrythrough. With the spar carrythough assembled, there is no access to some of the holes. As such, I dissasembled the F-604 and started to prep the seat ribs for installation. I deburred, dimpled, and primered about half the ribs. I also prepped the baggage compartment ribs.
