Will the NTSB report of the first NGs to suffer this problem take into account the reported defective structural parts supplied to and fitted by Boeing viz. the chord sections and the "bear-straps", which needed a hammer and/or some extra hand-drilled holes out of tolerance, in order to make them fit on the company's assembly line????

Sorry, I made that last part up, only joking!
