Thats a decent setup for a Hallmark movie - two travelers stranded and isolated find love through the zaney activities used to pass time in a remote locale.

Perfect for a Broadway play.

Then you’re going to have to ground all the 737-900ERs (in service since 2007) out there as well, since they use the exact same part. Or maybe, just maybe, this is 1,000x more likely to be a maintenance issue than it is a faulty design. If there were a genuine, ongoing safety issue worth worrying about pilots would stop flying them . People seem to entirely forget that the crew up in the cockpit are humans with an in…

Then you’re going to have to ground all the 737-900ERs (in service since 2007) out there as well, since they use the exact same part. Well, no. a.) The -900ER has exit doors where the -9 has plugs blocking off the doors. b.) If the problem was installation related then it would still make sense to ground the planes and inspect the potentially faulty aircraft.

> a.) The -900ER has exit doors where the -9 has plugs blocking off the doors.

The -900ER can and has come configured with the exact same plugs in those doors.

A maintenance issue on a ten week old plane?

That plane was literally at their OKC facility for maintenance on Dec 31, so… yes?

Planes are not cars. They don’t go in once a year to change the oil filter and tighten a few bolts.

"If it's Boeing, I'm not going." I was on a flight that made and emergency landing once, it was TERRIFYING. The pilot circled once then we went down at a very steep angle. What was even worse was the three days we were stranded in Gander Newfoundland while they fixed the plane and then flew in a new crew. It was basically an refueling/military base and not a real airport, no food or facilities. After that I never fle…

> After that I never flew without my toothbrush, change of clothes and contact solution in my carry on. You used to fly without those things? :O

It is more common than you can think of. Especially when people have a “base” both in their departure and destination locations.

For example i know a couple living a long distance relationship. They both have enough stuff at each others place so that they can travel very light.

Now of course it sucks if you suddenly get stranded in between, but it is not life threatening just an inconvenience. And from then on it is just a tradeoff. You can gain a small bit of regular convenience for the cost of risking a rare but moderate inconvenience.

Man.. if I hadnt seen it I wouldn't have believed it.That is absurd. How the FAA keeps approving this junk from Boeing is even more concerning than how bad Boeing manufacturing has become.

not much choice. Boeing is practically the only US manufacturer of widebody passenger jets and enjoys a privileged position as such. there is literally no other American competition for passenger air. Alternatives include the Chinese Comac 929, Sukhoi SSJ100, or A320 from Airbus. the first two are non-starters as most north american politicians are furiously opposed to the idea of carriers so much as looking at chine…

Why do people with no insight write walls of text on things they don't understand?

Was it made at the plant in North Carolina? Or in Seattle?

Stan and the gang will try and pawn this off on Spirit, but Renton is supposed to do high blow[1]. It's one of the last things that gets done, with hydraulics and suchlike. I'm just guessing here, but I bet someone waived a batch of Spirit stuff through the process to get more units out the door. "Eh, this whole block is probably fine". False Equivalence strikes again[2]. [1] Simulated full pressurization, often many…

Please, Stan the Man will blame the pilots, the passengers, the Wright brothers themselves before admitting Boeing screwed up again. Accountability left that company years ago.

Honestly this might lead to another 737 Max grounding, which will shoot up the cost of airfare. At this point, the 737 Max seems cursed.

Not cursed, just poorly designed. They needed to go to clean sheet design.

> you just experienced an issue overwhelmingly likely to be related to maintenance What maintenance? The plane was barely two months old and the part that failed was meant to be something installed permanently, not an emergency exit door that would probably see regular inspections. It's probably "just" sloppy assembly from Boeing/Spirit, which, yes, merit a grounding and inspection.

> What maintenance? The plane was barely two months old A plane is not a car. They don’t go in once a year to tighten some bolts and replace your oil filter. You have no idea how much is taken apart and reassembled on a regular basis.

A modern 737 has A / P1 checks every 500 hours. The plane in question has completed a total of 145 flights so it's quite possible it hadn't even reached the 500 hour threshold yet.

While emergency equipment like slides and doors are typically inspected with an "A" check, this wasn't an emergency door that failed. What failed was a permanently installed panel. To inspect it you'd have to pull off interior panels, something that doesn't typically happen on a 737 until a C check (roughly every couple of years or 5,000 hours).

So yeah. What maintenance on a nearly brand new plane would require pulling the interior apart and disturbing the emergency exit plug?

This wasn't a maintenance issue.

Edit: And, no, this plane was never at the Oklahoma City MRO.

I know myself and a couple other people who do the same, would be fascinating to see if it's common enough to show up in statistics. It's not even just the safety, the Boeing Dreamliner for example is shockingly uncomfortable to fly in.

> the Boeing Dreamliner for example is shockingly uncomfortable to fly in Struggling with this comment, I do a lot of long-haul and the dreamliner is a clear differentiator on arrival due to cabin pressure and humidity. Boeing seems to have made a lot of mistakes over the years but I seek out a dreamliner for anything over 8 hours. Perhaps you are the victim of the airline more than the aircraft itself?

I've done a few New Zealand to Houston trips on the Dreamliner and I find the vibration, temperature and humidity to be totally hostile compared to the A350.

Maybe it's a personal preference thing.

Well, this is my field so let's calm down for a sec and dispense with the hyperbole. The plane itself is not "fucked"; my understanding is the aircraft landed safely and nobody was injured. The door/window that departed the aircraft is a serious incident that will be investigated. There will be a report produced that identifies the root cause(s). >How does the maintenance crew fuck up a plane this badly in the span o…

This is a pretty arrogant reply. Whatever “field” you refer to, the problems at Boeing cut across disciplines and appear to go to systemic management problems. It’s not just issues engineering new systems. There have been well documented issues also with assembly and inspection. Boeing has a track record of recent quality problems at assembly time and even clashed with FAA on how to detect defects https://www.seattle…

Yes, software engineers should take over airplane maintenance because their track record at safety is just sooooo much better, right?

Airline industry has processes that work well and made flying ridiculously safe - there hasn't been a major plane crash in the whole of 2023! - maybe they know more about maintenance, accidents, investigations and corrective actions than a bunch of HN users?
