Several years ago Gary Hansen had a crack propagate along the inboard top
wing skin along his rear spar. By the time he discovered the problem it had
propagated along several aft spar to skin rivets (paint hid some of the
problem for a while). Only solution was to remove the wing and replace the
entire inboard skin. This is not an easy or fun job on the RV-6A as the wing
cannot be removed without removing the main gear mounts, you RV-7/8/9 guys
have it sooooo easy. I think the problem is more common than we hear about,
guys who have cracks in benign areas just stop drill them and don't give it
a second thought! Unfortunately Gary and his RV are no longer with us so I
can't ask him what he believed caused the problem.

..........This is the first report I can recall of a crack in any of the
wing skins. I think there was something unique about this situation....
