I clecoed/riveted the F-812 bulkhead to the F-828 aft bottom skin. I did the same to the F-811 bulkhead, and then riveted the rear face of the tail spring mount to the F-812 bulkhead, bolting the tail spring mounts front face to the F-811 bulkhead, I did have a very small gap there and used two spacers to fill the gap.
I then slid the two lower longerons into position on the F-811/812 bulkhead assemblies. I then clecoed the lower longerons, F811/812 bulkheads, and aft bottom skin assembly to the aft side skins. I clecoed the F-857C angles along with the seat belt anchors to the lower longerons.
The remaining bulkheads were clecoed into place, F-808/809/810B-1. I clecoed the F-808 bulkhead to the baggage ribs as well.
