Yesterday, rereading the plans I noticed that I had made a gross mistake in drilling the leading edge rins to the main spar. Some main ribs and leading edge ribs need to be redrilled. But the leading edge rib is sitting on the other side of the spar than the main ribs, and I drilled all the same way. On the picture, the spar has six holes and the rib flange only four. it should be the other way round, I should have used the spar as a drill guide and not the rib!!!!!!



I sent the picture to Van's, I think I will have six rivets on the flange instead of four.
