the torn-out hinges
Have not seen any photograph showing this detail. I would assume more damage to the end ribs if the fittings would have been torn off, unless the design is very poorly balanced between composites, metall fittings and fasteners. (which might be because the fittings are optimized for fatigue, and hence very strong in static overload)
The photo shows the external sections of both fittings are missing, but the separation occurred just above their attachment to the skin, which appears to have little to no damage or deformation. There is more of the aft external flange remaining than the forward flange on both fittings. The outboard leading edge is deformed aft, which from other photos of that corner, looks more like external impact damage than damage caused by the missing part of the fitting. Mike
