I'll still bet that the problem is one of ' casual ' final assembly issues at Renton. The basic picklefork attach is at Spirit in Wichita, and the final assembly at Renton is when wings are attached and the fail safe strap/picklefork is attached with the ' last' half dozen fasteners on each side. IMHO the ' fix' to be incorporated for the fleet will be to remove and replace the" last half dozen" with cold expansion ( aka coldworking ) re reaming, and installation of light interference fit fasteners.

And on those still on line at Renton, I'll bet such work will be carefully checked and or sequence modified starting on line # xyz123

I doubt there will be any significant changes in the picklefork itself
