Last week, when I clecoed the skin to the wing, I noticed that the front edge of the skin was not quite flush with the adjoining leading-edge skin. I discovered that this was because the factory countersinks in the spar flange were not quite deep enough. I re-countersunk the holes along the spar flange, and now the skin lays down perfectly. I also re-primed the line of holes.
Skin attach holes in the spar, re-countersunk and re-primed.
