While working on my wing today, I noticed that there was a split, crack or perhaps a scratch on my wing spar that I had not noticed before. I'm not sure how I overlooked this damage, but I can only think that the recent humidity made it a little more evident than it was in dryer weeks when I installed the ribs. I really could not tell if it was actually a crack, so I asked some other to take a look, and I also posted some photos on the forums. The feedback was not promising... many thought it looked like a crack rather than a scratch.
See photos below. The top edge crack (photo 1) actually extends further than is obvious in the photo.
