Back at it after I flew the Decathlon to cool off. NOTHING a little Acro can't fix! Separeted the Floor Stiffeners and deburred them. Clecoed the Floor Support Angle and one of the Floor Stiffeners onto the Front Seat Floor. Installed the Front Seat Floor into place. Match-Drilled the Screw holes in F-829A-1 Seat Floor to the F-805D Brackets. Removed the Front Seat Floor and deburred holes.
