All 737MAX fuselage structures are identical by model, regardless of airline customer. In the case of the MAX7, MAX8, MAX200 and MAX10, there is only one fuselage configuration in terms of exit configuration. In the case of the MAX9, the mid-cabin area can have either a plug or an exit door. I unde...

Jump to postThe NTSB chair Jennifer Homendy gave a presser late yesterday. Basically, they still aren't sure what the root cause of this was.

Jump to postDon't forget, under pressure there are literally tons of force pressing the stop pins against the stop pads. It's highly unlikely to move, even with missing bolts, loose hinge fasteners, etc, if those pins are properly centered and under pressure. My bet is we'll find out the locking bolts were miss...
Jump to postTrue enough, however the cost of the nut is trivial in this situation, e.g. the cost of the hardware should not be a factor, I would think.

Jump to postNTSB will very quickly determine who, and when, any work was done on the door plug.
You can't sneeze on something in aircraft maintenance without it being logged, so once they dig through the paperwork, they'll know exactly the timeline of any work done.

From the ATC audio I have listened to, AA was cleared to taxi along Bravo, and later, while still on Bravo, to cross 31L at Kilo in order to proceed along Kilo to the departure end of 4L (like Kilo One). No question the clearance was to cross 31L at Kilo, not 4L at Juliet. Ju...

Jump to postWell, Delta did write off a 747 (N664US) that experienced a massive amount of hail-induced damage after air controllers in China refused to allow a deviation around weather.
