Installing the Forward Bulkheads

I adjusted the flanges of the F-902-L&R Forward Bulkheads until the web was perpendicular to the aircraft centerline. I checked by using a straightedge between the two bulkhead webs to see that they were parallel. I straightened the bulkheads as necessary with flutes between the rivet holes. Then I opened the hole for the rudder cable to 5/8”.

I then riveted the nutplates to the aft side of the F-902 bulkhead. These would later hold clamps securing the fuel vent line.

I clecoed the F-7101 Gear Attach Web to the F-704 bulkhead. This rested the web of the F-902 against the forward flange of the F-7101.  I made some necessary small adjustments and then drilled and clecoed the F-902 to the F-7101 and the skin.

I adjusted the top and bottom tabs of F-902 as necessary to fit the longerons, and then drilled and clecoed.

Time:  2 hours.
