Is the FAA going to drag their feet again grounding this plane until the problem is root caused?

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…

The pilots have nothing to worry about. They're locked onto the cockpit.

You'll forgive me if I find your assertion strains credulity.

Did they shoot a movie with the plane before take off? https://www.npr.org/2023/11/10/1212144515/plane-missing-wind...

That just shows: you never know. Perhaps something had been done to this plane too, indeed. The only thing I would exclude at this point is bad maintenance. It's so unlikely that that part needed maintenance in less than 2 months. But your example shows we really should wait for the report.

And inspect similar planes in the mean time.

Do you think there will be any accountability from Boeing executives? Boeing hasn't had a lot of good press in the last few years, will leadership ever be held accountable? There was a time when Boeing was considered a very trustworthy and reliable company, is this the result of a decline in an engineering-focused culture? Edit: Many of the comments in this thread mention that they avoid the 737 MAX whenever possible…

Take that with a grain of salt but I have seen several people over the years claim this is due to MDD pulling a NeXT (getting acquired then taking over culturally).

Which is a bit of white-washing, considered that the original 737 not only had a design fault that led to accidents. The issue was rudder reversal caused by using single actuator instead of two, which turns out could "flip" part of its construction at times.

What about FAA execs? This is their job to make sure this cannot happen

And the delegation of certification happened because FAA was not given the budget to maintain enough experts on their own payroll.

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.

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.

From what I remember from the first 737 max incidents, the 737 max was designed as an iteration of 737 limited to the updates that would allow Boeing to bypass re-certification. The upgrades were significant and some, like engine placement, un-natural and clearly driven by regulation bypass.

I think it is quite logical that the added complexity results in additional failures.

It's going to be quite hard for the public to regain confidence in that aircraft, especially when (as noted elsewhere) Boeing was just now trying to get an exception from the FAA re: certification of the max 7.

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?

This is a form of ultra-BS

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?

Members of the public should be encouraged to ask how this happened because they’re the ones who trust their lives to these planes. The airline industries in places where the public couldn’t ask questions did not make flying ridiculously safe.

What strikes me with the ATC recording is that I can barely hear what they say (and that's the case with almost every ATC recording I heard before). And that's without being in a noisy environment (plane in flight). Is the quality really that bad? Doesn't that cause miscommunications? It seems like a fairly fixable problem in 2024.

LiveATC is crowd sourced. You take a radio, put it on your desk and stream that to their site. To get decent audio, you need a big antenna on the roof of your house or be in the air, like aircrafts.

I'm a pilot and even on very old planes like piper cub where the radio is just a desk radio added in the cockpit, the audio is much clearer. And with something like Bose A1 (noise canceling headset, A20 and A30 now), you hear it very well.

Most the time you hear ATC perfectly as they have very large antenna. ATC will hear you worse because of the noise around you, but with good mic it is still quite OK. They have large receiver too so you can be far. The worst audio is always plane to plane, there are some situations where your are far from a plane and only hear the ATC side of the conversation. But even if those situations, you can ask ATC to relay a message. It is very rare as you hardly have any reason to talk with a plane that is 100km away on the other side of a mountain.

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.

Doubtful.
