I drilled out the rivets holding W-414C-L Angle  to W-414A-L Plate & W-413B-R Plate.

Part W-414-L Aileron Hinge Bracket Assembly (installed by previous builder) was install canted inboard causing potential interference with the port aileron. The rivets were drilled out and a new W-414C-L angle was fabricated from AA6-125X1x1 stock. The other components of the W-414-L assembly were salvaged and re-used. Rivet holes were matched drilled from W-712-R Outer Rib and W-414A-L Plate and W-413B-R Plate. Vans calls out the mating surfaces to be primed. I use process of Alumiprep 33, Alodine, and AKZO primer.

The rivets attaching the aileron attachment point to the rear spar needed to drilled out a new part fabricated and match drilled.
