Is there confusion between "sheared bolts" and permanently inserted steel surface pressure-bearing rods set into the castings?
Note the two rods that slide in the casting with the lock bolts (or missing lock bolts). It's been suggested (
kghjfg) that they are too short for all fuselage stressed states. I note one can see a wear mark indicating how far into the sliding slot they have been sitting. There's a lot of wasted length.
