***Update*** The factory's recommendation was to cut the tab off and fab a piece of angle and attach it to the web and the spar. Had I not already attached the forward spar replacing the rib may have been an option.

Thanks for all of the help guys. And yes, pictures are very deceiving.

Default over/under driven rivets

Noting the above comments on over-driven rivets, I came across some interesting testing performed by a fellow RV-er:

That is very interesting. I would like to see that test re-done with lines of rivets, say four or five rivets long, with only one rivet driven out of spec. The 737 that had to make an emergency landing in Arizona after a top skin failed was found to have some poor rivets 8n a lap joint. The report, IIRC, noted that some rivets had snowman holes and possibly other defects. Failure of a single or small number of rivets caused a progressive load transfer to other rivets, which failed in shear in a chain reaction resulting in loss of the skin.

It would be very interesting to see similar tests done on a group of rivets, the bulk of which were correctly driven, with one out of spec, to see just how much that one rivet changes the joint strength.
