Began assembly of the flaps. Riveted skins to internal ribs, rivted top and bottom skins together near trailing edge. Installed strenghening brackets to the inboard rib, including plate nut for actuator connection, and bracket on flap spar. Riveted on the inboard rib. Partially pop riveted spar in place (need a angle head puller to get into the cracks). Riveted on the flap hinges.
Prepping for the upper surface skin to spar rivet run.
