Drilled
1) End seat ribs to side skins
2) Side skin to F623 rib
3) foreward portion portion of mid to aft fuselage rivets
Had a small edge margin on the bottom flange of F724 when back drilled using F623 rib as a guide. This is a common problem, I will probably use a doubler when riveting them together.
There are still more to drill.
The side skin is drilled to F623
The fit between F623 rib and side skin is not perfect at the aft end. I think the fit will be improved if the side skin is dimpled. We will see.
End seat rib is drilled with side skin
Conical bend is drilled
Center/mid fuselage are drilled together
F750 is clecoed to the baggage frame
