I clecoed the F-772 forward bottom skin back on the fuselage. I then drew centerlines on the back of the F-772B-R&L Floor Stiffeners. This made it possible to watch for the centerlines while shifting the stiffeners to fit them to the F-772 skin correctly.
When the floor stiffeners were located, I drilled them to the skin, firewall, and center section bulkhead. The center floor stiffeners were also drilled to the bottom of the F-783B-L&R Cover Support Ribs and F-601J angles on the firewall. I made sure the stiffener was firmly against the floor and bulkheads before using an angle drill to make these holes.
I also installed the rudder pedal/brake assembly with three sets of mounting holes.
Time: 5 hours.
