    United Airlines… did not confirm how many planes had loose bolts

    If it was just a few, they would have confirmed how many

      I doubt they would confirm before they had tested every bolt on a few planes

      Or at least one, testing every bolt, or at least this bolt on a bunch of them

      But they would need a sensitive tool to measure torq needed to unlock it that’s kinda cool

      Generally in Aviation, bolts are torqued down to a spec and then they are wired to prevent them from coming loose. I’m not an engineer but this happening on soo many planes looks like a manufacturing QC problem.
