Added the upper skin proteciton plate to the upper wing skin. The purpose of the plate is to protect the wing skin from possible impact from the aileron balance arm. This was a simple task that took under an hour from start to finish.
The protection plate on top of the wing for measuring/drilling.
The protection plate (still on the outside of the wing) aligned with the internal aileron balance arm.
The protection plate rivet pattern on the wing surface. It's now inside the wing skin.
