Clecoed the Footwells in place, Final-drilled all #40 holes in the Front Seat Floor, dissassembled and deburred all holes. Deburred the Aft Control Mount. Machine countersunk the Floor Support Angle and F-805F-1 spacer nutplate rivet holes. Drilled #40 holes in Outboard Seat Rib Angles to accomodate nutplates for the forward bolt of the Flap Weldment bearings. Deburred these holes, machine countersunk, and riveted the nutplates in place. Pneumatic squeezer worked just fine for riveting in this space, but it was a little tight and required a little thought before proceeding.
