I'm working on page 13-05 and step 1 says to final drill #30 the five holes between the spar doubler and spar web, then rivet them together using AN470AD4-6 rivets. Easy enough, except for one detail. On my left spar, the hole in the spar doubler is already larger than a #30. I have not drilled the holes yet and noticed it. The hole in the web is slightly undersized (as expected), but the hole in the doubler is definitely too big. An AD4-6 rivet fits loosely into the doubler hole with room to spare. Checking down the left spar where the ribs gets attached to the web/doubler, those same five holes in the doubler are larger than #30. I estimate them to be a #28 hole. Again, this is only for the hole in the doubler, not the web side.
My right spar does not have this problem.
Did anyone else notice this in their left spar? I cannot think of a reason why it would be this way.
Van's is off tomorrow but I was going to call their Builders Support on Tuesday. Until then, if anyone has any insight into this, please reply.
