Prime painted the Aileron/Flap Gap Fairing early this morning. The fairing connects between the wing aft spar and the underside of the upper wing skin. The wing skin was dimpled to accept the counterset rivets. Where the fairing attaches to the aft wing spar, standard #470 rivets were used in all places except the six most inboard on each wing. The six were countersunk to provide clearance for the flaps.
