Found all parts and started by preparing the 803 flap spars by edging and deburring. Drilled and clecoed the 704 and 705 ribs to the spar then cleoced the assembly to the bottom skins. Made the spacers and then srilled the ribs to the rear spar. Drilled the ribs to the bottom skins and drilled and clecoed the hinge. Dimpled the skin and machine countersunk the spart per plans. Fitted the top skins to the assembly and drilled holes along the bottom of flaps.
