MAX must stand for "MAX Profits" because they sure cut lots of corners on that aircraft.
After looking at that diagram I have to ask - why in the everliving fuck would a pressure bearing panel like that be hung by bolts and not inserted into the cabin and held in place by the ribs of the fuselage? I mean seriously?
I don’t get why they don’t just make it a bit bigger on the inside so that when pressurized, the pressure itself seals it. Seems like a fail safe solution instead of this shadiness.
But mah profits!
737 Max is still a developing example of what happens when you leave corporate to self-regulate themselves.
It's a well documented that when Boeing merged with McDonald Douglas, they turned from an engineering led company to an executive led one & have been shit since

It is, kind of. The plug is secured by 6 stops (or tabs) along each side. The positive pressure differential pushes the plug outwards into those stops.
To remove the plug you uninstall 4 bolts which allow the plug to go up and over the stops, after which it can hinge outwards on a hinge found at the bottom of the plug.
It’s a door plug, which means it’s meant to be replaced with an actual door if required, so a lot of the hardware for an actual door are in place. Doors are designed to slide in, then raise up so the stop pins engage the stop fittings from the inside, so the door is in effect bigger than the hole it’s in. this video provides a detailed explanation of how it works.
The big issue here is that the airplane is only 2 months old, it was delivered from Boeing in late October. Which means it’s either a design flaw or a process flaw in the original manufacturing. This smacks of corporate cost cutting again. Boeing are totally on the hook for this and it’s only lucky there were no lives lost. You watch, they’ll blame it on the airline initially but the fault will come back round to them again.
This is the best summary I could come up with:
Bolts in need of "additional tightening" have been found during inspections of Boeing 737 Max 9s, United Airlines has said.
Inspections began after a section of the fuselage fell from an Alaska Airlines 737 Max 9 on Friday.
United Airlines said "installation issues" relating to door plugs would be "remedied" before the aircraft type would return to service.
In its statement, United said: "Since we began preliminary inspections on Saturday, we have found instances that appear to relate to installation issues in the door plug - for example, bolts that needed additional tightening."
The door plug is a piece of fuselage with a window that can be used as an emergency exit in certain configurations.
It was this part of the Alaska Airlines plane which dramatically fell off mid-flight over the US state of Oregon, eventually landing in a teacher's back garden.
