The Airbus manual does say the door will unlock in the event of a decompression. It does not state if it will blow open but I suspect it would.

Boeing CEO took responsibility for “quality escape” in their manufacturing process. Didn’t blame Spirit Aerosystems even though they were the ones that built the fuselage. Said that though the quality component had “escaped” their factory, it also “escaped” Boeing’s assembly,

If anyone from the training department is headin North today from the training department, maybe swing by Boeing and drop off one of those Swiss cheese diagrams and a threat and error management checklist on your way home. Sounds like they could use it up in Renton.

Thats not true. Airbus door swings IN. So it would only blow open due to a failure forward of the cockpit bulkhead. And with triple locks, if it all.

You are mistaken. That's what blowout panels are for. And the door doesn't open outward on the Airbus.

Except the exact thing happened to a Delta A320. Rapid depressurization caused the door to open.

Yep…. His words… not mine….executive speak for epic failure.

That’s ok. They got three wars the defense side is making money off of, so what’s a little “quality escape” between friends? Amahright?🫤

There is almost no chance of that happening. The amount of time someone occupies that space is so small it doesn't matter. If someone is using the bathroom right as the cabin experiences an explosive decompression, thy could be injured if it happens right before they can open the bathroom door. If they manage to open the bathroom door, that door will take the majority of the impact. And then even if that happens, half the time their back will be facing the door causing their back to take the impact. Only 25% of the time of an already very small window will their face take the brunt of the impact. There are much bigger risks we take. If you are worried about that, why even bother have FAs walking around the cabin?; Everyone should be belted into their seats at all times.

Chalk that up as another in the "should be good" category of the guppy.

That is interesting. So the door unlocks and swings freely. Which means that in the event of an aft explosive decompression, the door would unlock and the door would swing forward against the escaping pressure.

I don't think the door swings freely but I suspect a decompression will let the door go either direction with the locks released.
