What's the source of this and is there a URL? Found, James Fallows at The Atlantic ; https://www.theatlantic.com/notes/2019/03/heres-what-was-on-...

You can't link to these on the ASRS site but that's the primary source. https://titan-server.arc.nasa.gov/ASRSPublicQueryWizard/Quer... put in ACN = 1555013.

This was how I found it, just cruising stories that mentioned the 737 MAX. It's a very interesting resource.

I think both end up with blame on Boeing. If a discussion in world news isn't enough to prepare an experienced 737 pilot (ten years!) to counteract spurious MCAS, then nothing is, at least to the level of safety expected in airline travel. A plausible explanation for (1) that I've seen discussed is that, after disabling the auto trim, it may be impossible to manually re-trim while the yoke's pulled back, without firs…

I think it's unlikely that this crash will be attributed to the same set of circumstances as the lion air crash. I don't find it credible that an experienced pilot would fail to catch what, in essence, is a trim runaway event. There is a reason trim runaway is a memory item on almost all aircraft. Even in the Lion air case the previous flight experienced difficulty with the system and dealt with it. This was before t…

>Another failure in the AoA sensor on a brand new aircraft seems unlikely.

From another perspective, having one new sensor fail would seem to suggest that one should increase the prior probability for failure.

To clarify, I meant passengers. Copilots and engineers are fine and likely even necessary to properly train and deal with the new challenges. As a daily driver of your own car, if you do own one, then it might be apparent how different they can be. I constantly switch between automatic Mercedes and BMWs. Both have a near identical handle on the right side of the steering wheel. One turns on wipers (BMW), the other on…

You don't do non-revenue training flights on full-size jetliners. It's way too expensive. You learn to fly (period) on small planes that can't hold passengers at all, then you train in simulators for a specific model, and then finally you're paired up with a more experienced pilot once you start flying it for real. They definitely did not do the proper training that was merited here, but the proper training is not an…

Funny enough, I remember seeing a 737 doing circuits at Prestwick airport. I believe there is (or used to be) some requirement for an airline to do a minimum number of circuits on a new type. Kinda fun to see. Apparently a lot of fun for pilots to do.

Let's preface this by saying I am aware that cause of the accident has not been determined. Seeing reports of experienced pilots being assigned to 737 MAXs without prior flight experience of this precise model, prompts me to make this comment. As a passenger I expect pilots to fully know the plane they are flying and to previously have flown this exact type and model of aircraft in training sessions without any passe…

You have no idea what you’re talking about. Pilots already warned Boeing about the problem: https://globalnews.ca/news/5055894/u-s-pilots-warned-boeing-... Boeing ignored it.

The fact that pilots have already warned Boeing does not imply that OP "has no idea what they are talking about."

Your reply was unnecessarily hostile and your downvotes are well-deserved.

This kind of accident doesn't happen for just a single reason, they happen for a SERIES of reasons all together. Some of those reasons are technical, some are environmental, and some are human factor. Blaming any single of them is bullshit... and so is forgetting about any of them.

1) boeing changing geometry 2) boeing adding a new system that takes over control without documenting 3) pushing very hard to classify a new plane as an older type so now retraining happens 4) using only 2 sensors instead of 3, and using just one to control parts of the plane. A series of reasons

Oh so the NTSB report is out? Can you link it? Thanks.

I am just a passenger without aviation experience. Nonetheless, how does your link invalidate my comment? To reiterate, I see following issues:

1) Software issues (e.g. MCAS), hardware issues (e.g. AoA sensors) -> Boeing responsible

2) Little to no training for 737 MAX, shuffling of known UI and UX of other 737 models -> airlines and Boeing responsible

3) Certifications for 737 MAX granted despite lack of sufficient training in addition to repeated warnings by pilots (your link!) -> Boeing and FAA responsible

That was a terrible experience trying to search for that report.

I have no idea why many government websites (not just US) are like this; making things that are obviously not stateful (like viewing a report or search criteria) session-wide state. It almost feels somewhat intentional to prevent linking to resources.

That's fair. It would be interesting to find out whether it was an existing sensor, used on other aircraft, and what the reliability is like. But I doubt that information is readily available.

Narrative from ASRS 1555013: I had my first flight on the Max [to] ZZZ1. We found out we were scheduled to fly the aircraft on the way to the airport in the limo. We had a little time [to] review the essentials in the car. Otherwise we would have walked onto the plane cold.My post flight evaluation is that we lacked the knowledge to operate the aircraft in all weather and aircraft states safely. The instrumentation i…

The problem is that if they had invested so much effort in training crews for the differences in the Max, it would be an admission that the Max and NG aren't so similar after all. Making it look like a quick and easy switch is only making the problem more serious.

This is why corporations cannot police themselves and it's where the FAA dropped the ball.
