Brief Description: Installing the Flap Brace and Aileron Gap Fairings
I decided to test fit everything before final riveting the aileron gap fairing to the rear spar, and noticed that an edge in the outboard end of the W-724 Aileron Gap Fairing would interfere with a rivet in LH W-414 Outboard Aileron Hinge (pic 1). So I took both gap fairing off and trimmed that edge .145" less to clear a gap with that particular rivet head. Since RH is basically a mirror of the LH, I took care of RH gap fairing as well. Then came deburring, and priming both parts before getting them ready to rivet in place.
