At about 520 tach hours, our 180hp RV-6 is developing cracks in the 0.016 elevator skins. These cracks are at the leading edge, not the trailing edge. I want to stop drill them while I think about building new elevators out of .020, but the ends of the cracks are right over the spar flange:
Anybody have advice for stop drilling cracks in this location? How important is it to avoid drilling into the spar? And what's the best way to avoid doing that?
Thanks in advance for any help,
