Quote HistoryQuoted: IIRC most flights are pressurized to about 8k ft and it blew at 16k ft, so yea, there abouts Quote HistoryQuoted: Quoted: There'd be about what, a ~3psi differential when the door liberated? But, that's an ~8000 ft cabin equivalent up at max cruise. There's a sloped pressure schedule on climb and descent. I'll see if I can find some charts. |

Quote HistoryQuoted: What is a "plug door" and why are they deactivated for pax jets? I have no idea. But, this is a mid-cabin emergency exit (a bit different from the wing exits) and while it should have in-flight lockout mechanisms, it is most certainly not "deactivated" in flights with passengers aboard. |

Re Door Plug ….
The international MAX variants (mostly Asia) have high density seating that necessitate another exit door. For jets in the US, they install a “plug” in that space. |

My understanding is that the fuselage is built with the opening for a door there, but depending on cabin layout and number of passengers, some of them (like this example) have the holes plugged instead of getting doors installed. It looks kinda like the fasteners that hold the plug in failed. |

A plug door is a door that is not used and not part of the evacuation procedure. As you can see from the pics, there are rows of seats in front of the door. This door can be reactivated if the seating rows are adjusted. Basically the seating configuration determines if the airline wants to use the door or not.
Airbus does the same thing on A321 and A321 NEO. |

Quote HistoryQuoted: Quoted: Airline mechanics, what are we looking at? It's not a door, it's a plug, which isn't supposed to be like a door, but turns out it is more like a half door, because while it has no way to close, it can apparently open. |

That door is not a plug door, it opens outward. A plug door is made so that it stays in place due to cabin pressure making it fit tighter, therefore they open inwards.
The doorframe latches appear to still be in place and I can’t see much damage due to shearing of the locks. The ones in the door will be interesting to see. |

The spacing between those rows isn’t far enough apart to be an emergency exit, IMO. I think the whole panel around the window separated. I know the new A321NX’s have an overwing emergency exit that is a door that pops/swings up when you pull the handle. But, those are over the wing. This looks like it’s not near the wing. ETA: This pic does look like one of the pop up exit doors.  Attached FileStill doesn’t look like enough room between the roses to me an exit. |

Quote HistoryQuoted: https://www.ar15.com/media/mediaFiles/227964/Delta_Airlines_Boeing_737-900ER_K65993-3-3083523.JPG That "hole" matches up rather suspiciously with the emergency exit towards the tail. The one about 9 windows back from the wing. I guess in some less dense seating arrangements, that emergency exit isn't needed and paneled over and probably some other stuff. The "probably some other stuff" part might be where something went wrong. |

Two month old 737 Max-9. This doesn’t look good for Boeing and if the investigation uncovers a design problem that’ll ground the fleet, again.
Look for other carriers to ground theirs for a detailed inspection, as soon as tonight. Going to be a few delayed flights tomorrow. |

the oxygen masks are a metal tube that activates when the pin(kinda like on a grenade) gets pulled.So if ever you need to put on your oxygen mask
pull the mask hard so the pin releases.the masks use a chemical reaction in the tubes to provide oxygen--and get really hot. I used to be the "king of the oweed"(over wing emergency exit door) and told the engineers what was wrong with their design.on the airbus A220. I also used to do all the NCR's on the rear plug door on the bombardier 900 series regional jet.the plug door was not used so they installed more seats there-- and I had to rework all the area for more seat rails. That failure was a total cluster fuck--someone in production didn't close off that door properly.You can see the mounting points for that door. honestly,American aircraft production leaves a lot to be desired.I inspected Airbus A220's made in the USA and the shit I saw would NEVER have passed in Canada--I did audits. |

Quote HistoryQuoted: Airline mechanics, what are we looking at? The way I see it there are only two possibilities. 1. Someone actuated the handle. 2. The door was not latched before departure. I don't work on the 737 but the door stops around the frame will not allow the door to move outward unless it is shifted away from them (by the actuating handle and operating mechanism). Not always, but there is usually electronic door indication by microswitches, so if the door was unlatched before takeoff, a crew doing their job would have noticed this on their EICAS or MFD. I would say there is more chance that one of the passengers opened it at a low altitude before differential pressure rose to the point where friction would make the door extremely difficult to open. |

Movies tell me that when this happens, the emergency masks drop and the flight attendants start flying out towards the hole until they’re able to grab onto a seat while other passengers help.
