Such a crappy aircraft - can we just get rid of these already?
Bolts can be loosened, or fail to be tightened on any aircraft. I suspect this may be a problem with people and/or procedure.
So, about that Max 10 on which you were hoping to get fast-track approval...

> It means people were careless and sloppy during assembly. Maybe. Could also be incorrect torque specs, bad parts, unexpected vibration in that area, etc. Edit: Yes, none of these are good either. Just saying there are many possibilities.
Those don’t sound very reassuring either. What’s to say that this is the only bolt with incorrect torque spec, or if this part is bad why not others, and if bad parts are not being caught during quality control then what other parts will be next to fail prematurely? And if there are unexpected vibrations in that area, why wasn’t it discovered during test flights? What other vibration issues would they not have accoun…
Check out this video showing how the plug is supposed to be installed: https://youtu.be/maLBGFYl9_o?t=540 Some of the bolts that would be loosened when the plug is opened during maintenance have a pin to prevent them from turning. That pin is present in this photo: https://x.com/byerussell/status/1744460136855294106?s=46&t=s... However, the same photo shows other critical bolts that hold the whole hinge on the door a…
How were these not noticed in proper inspections? Is this the first time these planes have been inspected?

Force it to develop actually new airplane, not rely on grandfathered type license from 60 years ago.

Or it means the torque specs were a little too low, or too high and stripped, or the bolt threading was defective/spec’d wrong. Or bad metallurgy. Or the spec didn’t specify which order to tighten the bolts, so which direction you go causes different outcomes. Lots of stuff is assembled consistently and carefully “wrong”, but as specified.
Some part of the process -- anywhere from specs to assembly-- had some cost cutting that led to the outcome. The root cause of this problem is something financially motivated.
