I can't beleive I did this...
While riveting the front HS spar, I had a rivet with a shop head that was too small (I think I might have picked up the wrong size rivet). It was the only blemish to an otherwise perfect riveting job, and I just couldn't have one bad rivet, I felt compelled to fix it. In hindsight I wish I had just left well enough alone!!!
I decided to drill it out and replace it, so I flipped the part over on the bench, and then walked over to my tool chest to grab my drill. I then walked over to the part and proceeded to drill. I flipped it back over only to find out I had just drilled out the WRONG rivet. When I re-riveted the hole, I bent the rivet over badly (grrrrr), so I drilled it out (again). Unfortunately, I had to drill the entire rivet out to remove it. When I flipped the part over I found that the back side of the hole was now enlarged (egg shaped) and I had now violated the 2D edge distance on the HS Spar Reinforcing Angle HS-710 by a pretty big margin (it was pretty close to begin with). Now the explatives really started to fly!!!
I called Vans this morning and sure enough, due to its critical nature, HS-710 needs to be replaced. [Insert more explatives here]. That's about 14 good rivets to drill out, and now I have to fabricate/replicate HS-710!
Scott (at Vans) gave me the impression that the enlarged holes in HS-405 (rib) and HS-702 (front spar) are not as much of a concern as the edge distance on HS-710. One thing I forgot to discuss with him is... should I be concerned with a minor edge distance infraction (say 1.5D) on the front flange of HS-405? I would like to avoid replacing that part as it is match drilled to the skin, but I will if I have to. Your opinions??? I am not sure I even have problem there as the hole enlarged away from the edge, but if it might be an issue I might just have them throw an HS-405 rib into the order before it ships.
Moral of the story... Vans says to leave minor rivet problems alone and build on... trust me, they are right!!!
Regards,
