I spend most of the time on the elevator, I believe the trailing edge was supposed to have pre-drilled holes. I proceeded to spend quite a bit of time in match drilling, due to limited space, I proceeded to drill at an angle from the one side, and then drill through the same hole to the opposite side. Everything was removed, deburred. I also bend 1.1/4 the leading edge of the elevator, everything was deburred, sanded. I also reviewed my one center rivet on my trim tab. This rivet will be replaced with an oversize rivet- see picture
