The purpose of FT is to be an informative forum that, in this case, enables the UA flyer to enhance their travel experience. There are other forums for different types of discussions. This thread was had wide latitude but that latitude is being abused.

Bottom line, if you can not stay within the FT rules and the forum's topic areas, please do not post.
And before posting, ask if you are bringing new contributing information to the discussion -- not just repeating previous points, then please do not post.

Discussion of Boeing's culture or the impact on Boeing's future is not in scope. Nor is comments on restructuring the regulatory process. Neither is the impacts on COVID on the general air industry -- those are not UA specific and are better discussed elsewhere. And for discussion of UA's future, there is a separate thread.

Additionally repeated postings of essentially the same content should not happen nor unnecessarily inflammatory posts. And of course, the rest of FT posting rules apply including discuss the issue and not the posters.

United does not fly the 737 MAX 8 that has been involved in two recent crashes, but it does operate the 737 MAX 9.

How to tell if your flight is scheduled to be operated by the MAX 9:

View your reservation or flight status page, either on the web or on the app. United lists the entire aircraft type. Every flight that is scheduled to be on the 737 MAX will say "Boeing 737 MAX 9." If you see anything else -- for example, "Boeing 737-900," it is not scheduled to be a MAX at this time.

The same is true in search results and anywhere else on the United site.

For advanced users: UA uses the three letter IATA identifier 7M9 for the 737 MAX 9.

All 737 MAX aircraft worldwide (MAX 8, MAX 9, and MAX 10) are currently grounded.

It's already come through. The audio was leaked. The pilots were apparently unaware that they were being recorded. https://www.cbsnews.com/news/boeing-...es-2019-05-14/ This is old news.

The pilots were almost certainly speaking their minds in what they thought was a private setting. The decision to leak the audio was likely motivated by (as you say) politics, posturing, and union negotiations, but the actual content of the audio is almost certainly honest.

And, again, there was Capt. Sullenberger's testimony in front of Congress.

Some here have implied that because we have one expert posting here, we should just take his opinion as gospel. My point is that that doesn't really make sense, because we have the exact opposite opinion from others who have the same level of expertise. The only thing that we can really conclude is that the experts disagree.

And...if this was truly simply a matter of providing training or re-training to pilots on how to recover from a runaway stabilizer trim...then why is the plane still grounded? Why not simply roll that training out and be back in the air quickly, without all the attendant cost accruing now?

I haven't seen anyone saying to take anyone's opinion as gospel, and we have no way to judge the level of expertise of either the pilots who contribute here or the AA pilots who were recorded. When these comments first came out, someone asked about them; my response then, as it is now, is that pilots are human too. I can sympathize; there was little solid information about what had happened.

There's also a difference between saying that Boeing should have provided this information (I agree) and that they needed to provide this information in order to allow for safe operation of the plane (I disagree). Every system should be documented, but that doesn't mean that every pilot should be required to memorize the minute details. If there were a new procedure due to the MCAS, then certainly they'd need training for that. There wasn't.

Because Boeing -- and the regulatory agencies, and the flying public -- would rather not take the risk that another crew will ignore the proper procedure if a runaway stabilizer should occur?

This isn't particularly complicated:

1 - It is possible to recover from a stabilizer failure
2 - If the stabilizer on the MAX is substantially more likely to fail than the stabilizer on the NG, it is appropriate to address that tendency.

Both of these statements can be true simultaneously.

There is no such thing as a perfectly safe plane. A stabilizer could fail on a 737 NG tonight, and it could end up precipitating a crash, because airplanes are imperfect, and pilots are human. It just makes sense -- for everyone involved -- to improve the MAX so that it will enter an emergency state less frequently.

This is quite different from the “ground the plane forever because people died” mindset.

A core part of modern aviation is continuous improvement based on exhausting analysis of robust data sets. While I - and many others - are confident the MAX could continue to be operated safely, regulators identified items that needed to be changed to improve safety. Because of the initial hysteria, it would be imprudent to return the airplane to service until these items are completed, even if the aircraft could be operated safely.

Which post, anywhere on this thread or others, has ever said "ground the plane forever because people died?"

I know that some posters believe the plane is inherently unstable because of the position of the engines, so they are saying "ground the plane forever because it's an awful design. " That's significantly different than your posit.

Because of the initial hysteria,
It is just as inappropriate to use the term "hysteria" as it would be for me to describe MAX advocates as "heartless."

it would be imprudent to return the airplane to service until these items are completed, even if the aircraft could be operated safely.
Apparently at least the Europeans are discovering more "items to complete."

https://samchui.com/2019/07/10/easa-...topilot-fault/


The five requirements the European Aviation Safety Agency have listed so far are as follows:
  • Reduce the difficulty manually turning the trim wheel
  • Address the unreliability of Angle of Attack sensors
  • Address the training situation
  • Investigate software issues with a lagging microprocessor
  • < the autopilot failing to disengage in certain emergencies>

Please re-read my post #1977 . The audio you noted was the confrontation with Boeing officials - not at all what I was referring to. That is old news as you correctly stated.

The initial confrontation between APA and AAL management about the MAX prior to the ET accident is why that particular pilot group is so vocal. Not only were they misled by Boeing, (as were all B737 Pilots), it was their own company leadership that was (allegedly) less than supportive. It is my understanding that they knew there was an issue but concerns were quickly dismissed. These guys are pissed, feel betrayed, and the repercussions are working the way up the chain through Boeing and now to Congress via Sully; a great man but still from the family (via USAPA). He is obviously an intelligent individual and fully capable of handling himself, but the pre-testimony brief and fact prep before Congress was definitely not done by ALPA, lets be honest.

Sully is not going to stand in front of Congress and place blame solely on third world pilots with little flight time, that's not going to happen. However, I'm afraid to say that a lack of experience will be a contributing factor in each of these accidents. The botched recovery procedures for Runaway Trim at uncontrollable speeds unfortunately paint the picture of a complete lack of situational awareness.

Capt. Sullenberger's narrative was that Boeing is culpable and they deserve to be accountable for these accidents. That's the message he delivered, one that lines up nearly identical with the APA public campaign. I personally thought he did a great job.

From that article:

Past and present engineers within the aviation industry have flagged the aircraft as unsafe to fly because it is not a software problem, it is a structural problem that required the MCAS system in the first place.

This is exactly what I've been saying all along, since the beginning. The problem is not that MCAS sucks, the problem is that the plane needs MCAS. Fixing MCAS does not fix the problem.

And has been said before, nearly every commercial airplane has a pitch augmentation system.

Every trim runway (from the electric trim system itself, or any system that can actuate the electric trim system like STS or MCAS) is automatically initiated by the aircraft. Otherwise it wouldn't be a trim runaway!

Something is very wrong, new airplane should really be less at risk
Your "simple perspective" on risk is literally the opposite of how any new product works. New products have more risk.

First and foremost, politics. Also, public relations.

No the MAX remains grounded because "politics" along with "public relations" broke Boeing's grip over the FAA. The FAA is now doing the type of testing of the revised MCAS system that was not done before MCAS was rolled out. As part of that testing, other safety issues were identified, which Boeing is now required to fix. The EU evidently also identified issues with the Autopilot that they want fixed. See generally. https://www.washingtonpost.com/busin...=.b1ef697af252

The MAX is grounded because regulators are now looking carefully at Boeing's handiwork, and not liking what they are finding. I am not suggesting that if you looked carefully at an Airbus or any other jet you might not have similar issues crop up, but real issues, not "politics" have kept the MAX grounded.

The entire MAX program was a rushed response to the neo, with Boeing responding to AAL's purchase of the A320/321 and threat to place another big order unless Boeing got off the pot. Yet, the situation was created by Boeings's failure to come up with a new narrow body, which was the result of an unwillingness to invest and the lack of engineering resources with the 787 issues. Boeing is now paying a heavy price for its now 15 year strategy of trying to maximize profits by offshoring and reducing investment.

Kinda like the sufficiently detailed technical explanation of MCAS that Boeing offered to airlines and operators prior to unleashing this hot mess on the world?

Agreed, unfortunately the 737MAX returns us to roughly to about a 1950s level safety. There was absolutely no improvement on that with this aircraft, only decades of regression.

And yet somehow the rest of the world's aircraft don't typically tend to fly themselves into the ground at a rate of 2 every 5 months.

Which is why the airplane is grounded until changes are made...

There is critical loss of nuance in this discussion. Until there’s are accident reports and an understanding whether any deficiencies in design were the result of Boeing’s negligence, placing blame is hysteria.

Although it is a tragedy that people died, we have to move on.
