While the aileron brackets were drying I went to the next step which was to debur and fit the two W-721 flap braces. I started by marking the two trim areas as called for by the W-721 trim detail on DWG-14A. After cutting I checked the fit on the wing rear spar. Next I deburred the edges and all the lightening holes. Last I clecoed the flap braces to the wing aft spar and the bottom wing skin for match drilling of all the rivet holes.
