[quote]If I'm reading and viewing all this right, the likely failure would be a wing skin panel tearing free from the ribs at the attachment point (the little dog-biscuit-shaped "feet"). Correct? [unquote]
Don't think so. The likely failure would be that one bolt (out of over 100) would not be transmitting torsion from skin into that one rib. The ribs don't carry any bending loads, just torsion and curvature crushing loads between top and bottom skins.
