Have plane together, PAP mostly done, taxi tests done. Wing pins are in, wings solid (no play) but the pins are tighter than they should be. The wing skins are clear.
Left wing pins fit nicely. Right wing is the issue. At first, it would not go all the way in. Measured all four tabs and found that the aft tab on right wing was about .003 wider (taller?) than the others - trimmed it to match the others. All now 1.5002". Used a 1.5002" washer to check the four sockets. All were good at that dimension - no "play" with the washer. But right wing would still not go quite all the way in. Then did some very light trimming of the ends of the right wing tabs to get to the present situation (wings go on but tight pins).
Called Van's. They told me to just keep trimming and fitting until wing pins go in easily. I want to figure out which tab to trim. I do not want to trim from the tab that is already OK and wind up with pins that go in easily but some fore and aft play in the installed wing.
Wondering what others have done to identify the offending tab.
