Ailerons & flaps had been stacked with shop rags between them then taped together with duct tape, presumably in 2008. Took a long time to get them apart and all the 11 year old tape residue off of them. Both had -3 rivet holes that hadn't been set at the rib T.E. due to tight space for a squeezer. I was able to get them with a ground down no-hole yoke. In one case, there was already a pull rivet in one flap, so even though I could have set a rivet, I put a matching pull rivet in the other one so they would be the same side to side. Also did a quality and conformity check against the print. The only significant thing I found so far is that on one aileron, there are pop rivets missing from the aft side of the counterbalance pipe common to the nose ribs. They drilled the holes, and then evidently just forgot to put rivets in the holes. Space is too tight to get a pop rivet gun in there now that it's all together and I don't have any confidence that the angled technique with the mandrel going through a wedge will work. I think that the angle required is too great. I will have to ponder this a while. I've also asked for input from Vans Airforce forum and will see if anyone has suggestions. If I can't come up with a better idea, I could always put a machine screw and lock nut in there, but that seems like a clunky solution.
