[@Evil_Knievel]

I was flying with American Airlines from Frankfurt to the US in December 2019, or let's say, I was supposed to. Thankfully, a conscious pilot decided to turn back to the gate as he noticed a small error. It was really not a big deal but didn't want to put his passengers in danger and turned back immediately. Even though AA had to manage to rebook all the passengers and to somehow get us to the US, plus pay for the canceled flight because of technical issues, I was very thankful that the pilot decided the way he did. No money on earth brings back dead people.. Thank you!

[@halleffect1]

it's crazy how they could design a system that takes full control relying on a single sensor that can fail. Even the drive-by-wire accelerator pedal in your car has triple redundancy.

[@MikkoRantalainen]

It was intentional because 737 already had automated stabilizer trim and the reasoning was that MCAS failure is no different from stabilizer trim failure. Both have similar endcome and both must be dealt with similar action. However, as far as I know, MCAS changes the trim faster which gives less time to pilots to figure out the problem. That was the part where Boeing was greedy and instead of requiring additional training for the pilots, the got FAA to believe that MCAS was similar enough to older system that it doesn't need any extra training. The pilots should have been trained about MCAS failure handling as a memory item even if it has redundant sensors because once it fails, you don't have time to search for the correct procedure.

[@mukamuka0]

The reasons is to avoid pilot training. MCAS is actually uses both sensors (Left & Right) but not at the same time. It's switch sensors between each flight and only one at the time for that flight. This has been reveal from whistle blower that Boeing know if they are using both sensors at the same time. FAA will required them to do additional pilot training in the simulator. This because by using both sensors, it will indicated that system is safety critical and pilot needs to be train on how to react if the system fail. Boeing deliberately designed MCAS to use one sensor, so they could claim that Max plane could save Airline money because it doesn't required pilot training.

[@MikkoRantalainen]

@@mukamuka0 Wow! I didn't know that pilot training is *required* if a feature is redundant. That explains the full MCAS failure!

[@abcddef2112]

Honestly it is still a bad design, its a software fixing a hardware bug. What is actually the solution for the mcas so the plane can be recertified?

[@chouseification]

@@MikkoRantalainen people keep saying "Boeing was greedy" but completely forget that it is the _airlines_ who have to pay to train pilots and who obviously coerced Boeing into cutting corners, and they had FAA help in that regard. Trying to blame Boeing but failing to see the big picture is tragic. It was the airlines who started this whole fiasco, by being too cheap to train their pilots - so they forced the manufacturer to issue an obviously different plane under the same type certificate, so said training could be avoided.

[@samtobio3045]

One of the documentaries said that Ethiopian pilots deactivated MCAS and they were in such a hard dive, that they could not manually adjust the trim. They turned the switches back on in the hopes it would trim up. Such a shame.

[@leulmamuye5437]

If you have seen the full documentary its also stated there if pilots didnt act in 10 seconds there is no going back. This 10 second was not mentioned prior to the ethiopian accident, they were just told deactivating will able them to take control back, no time limit was mentioned. Plus boeing was against the need of pilots simulation training towards max, despite the fact that the max has major system upgrade which can lead to fatal accident if action is not taken in less than 10sec( which they are expected to do without enough understading of the system)... the shame is on boeing! making them fly blindfolded

The problem it has often been said goes back to the Boeing/McDonnell Douglas merger. An engineer lead company, Boeing, was reverse taken over by a suit lead culture MD. An expensive false economy ensued. .

[@adewouters]

I don't think people or management teams in general knowingly took shortcuts on safety, for the sake of saving a few bucks on each flight, but unfortunately they also didn't know/understand/realize what were the consequences on safety of some decisions they took. The intention behind the MCAS was good I believe, but did they (want to) realize the side effects ? Perfection doesn't exist. The only way is to test, test, test and test again, in all kind of apparently stupid and meaningless situations. This takes time, a lot of time. And Joe is 100% right: don't rush, take all the time needed.

My father flew the 727 for years and retired on that airframe in 1990.

Since the relocation of Boeing headquarters from Seattle to Chicago in the mid 1990’s there has been a titanic shift in the focus of the company. It’s telling when a company moves its HQ from its center of R&D, design, engineering, production, and “ancestral home” to a financial center.

[@JxH]

I've seen people make the very strange claim that discussion boards discussing an air accident might somehow "distract" the official investigation. Utter nonsense of course. In the case of the 737 Max discussions, one forum appeared to include an employee of Boeing or a subcontractor (speculation alert) that was an active party to the discussions and they were making outlandish excuses for Boeing, and were actively concocting reasons for blaming the pilots. His claims were strongly refuted. It's fair game that a prominent KZbin channel (1.4M subscribers here) might wish to avoid controversy, and avoid getting ahead of the official investigation. That's fair and perfectly reasonable.

[@stever4899]

An important detail left out, there are two alpha (angle of attack) vanes on the 737 MAX, but originally MCAS was designed to operate off of only one of them. As an IT engineer I was livid to learn that supposed professionals at Boeing would create a safety critical system with such a glaring single point of failure.

[@cjmillsnun]

I still think there should be three AoA vanes on a Max. The A320 has 3 AoA vanes so that if one is faulty and gives a bad reading, the computers on board can isolate it as faulty due to the readings of the other two.

I travel the globe abit and honestly am still terrified of flying (unless drunk/drugged). Here's how I look at it. The A320 didn't have a great start either (Air France Flight 296). It literally "landed" itself in a wooded forest at the Paris airshow. Airbus blamed the pilot and did everything to stop people looking into their design flaw. The 737 Max is a somewhat similar story. Moving forward to 2021, the 737 Max is the most scrutinised aircraft in the history of aviation. MCAS was only the first issue (other issue arose and then many more for each alteration). I would have to say that if the head of the FAA is happy to stick his kids on it, then the problem is no longer with the plane. Keep in mind the flight before the Lion Air crash, MCAS did kick in and they took the appropriate steps and continued with the flight. The crew of the crashed plane failed to comprehend the power of MCAS on trim and it was until the aircraft was handed to the first office (who didn't put enough input to overpower the system) that the plane crashed. All planes have issues and like planes, airlines also have issue (training etc). I would rather travel on a 737 Max over any other plane (short-haul), minus 737NG (which are just amazing planes. Just keep in mind the amount of time spent to make sure this would never happen again. Happy flying

One thing I didn’t hear you mention, which mystifies me, is why Boeing designed MCAS to take data from only one AOA vane. Everything else on the aircraft has one or more redundancy. Neither of these crashes would have happened.

I've seen a suggestion that working MCAS off two vanes would somehow have highlighted it as a safety-critical system which would then have invoked heavier certification & training requirements. By just driving it off one vane they could pretend it was just an unimportant adjustment that nobody needed to worry about. (But I agree, just driving a system that had the potential to cause a crash, off a single sensor - and these things have a known failure rate - is just bananas).

Update : As of March 1, 2022 I - as passenger - have flown on 51 separate Max's. A quieter craft due, I will assume, to the engines which DO generate more power. The seats are no more comfortable (the worst!!!) - typical Boeing - but the cabin seems to be better ventilated.

[@jahbern]

That makes sense if you understand the aerodynamics (in the case of a plane). It’s basic physics. But it seems like pilots weren’t trained in the physics of this particular change. Did they not know about the change in engine placement - or more importantly what that would do to the center of gravity? And even worse, some pilots didn’t even know there WAS an MCAS - so why would the suspect something would be different with the cog?. My daughter is applying for university aviation programs and they spend quite a bit of time on physics and aerodynamics. College level classes. But what if you don’t obtain your commercial training at a university? Do those pilots receive the same training in physics and aerodynamics? I honestly don’t know. The pilots in those smaller, less wealthy countries may not have had the same training. It’s an interesting question I’d never considered before. Thanks for the insight!

The crazy thing to me. Is Boeing CEOs actually allowed for this to happen just to try to save a few dollars. An Airplane is one of the few products in the world, Where you should never cut corners and rush to the sales floor. Your business runs on razor thin margins already, there should be a an absolute 0 tolerance in ever thinking about selling a plane that is not 1000% optimal. When you make a good quality product, you won't ever have to worry about going broke. Because your reputation as being best of best will always keep you alive, and you will alway make sales without even trying as hard. Like seriously was it worth it that you saved let's just say 2 billion dollars ( yes it's a ton of money to save) but you rushing out a bad product that is literally in control of millions of people lives yearly. Now all your planes are crashing due to selling a less than quality product then normal. Your basically committing company sucied!

[@Lucarocks92]

Joe. MCAS was for type rating purposes not for anti stall. Due to the extra pitch the stick force gradient when approaching a stall was different from the NG and not getting heavier like it should. This is the reason for MCAS not to counter act a stall, it came down to keeping costs to a minimum for airlines not requiring sim training. Source Boeing website states MCAS is designed to 'enhance pitch stability so that it flies like other 737's." So many KZbinrs and people in the media are misinformed about MCAS and assume it's an anti stall feature which it is not.

[@GeordieBoy69]

No issues in USA or EU. Those 2 crashes happened due to airlines saving money by opting for 1 aoa sensor instead of 2. Also poor maintainence. 1st plane, previous captain reported issue, but maintainance did nothing, crashed next flight. 2nd plane, again previous captain reported issues, maintainance changed the aoa sensor but did it wrongly resulting in not working and plane crashed next flight. Again USA and EU no issues at all as they all put safety first and opt for 2 aoa sensors. Plane cannot nose dive unless both aoa sensors agree. Hence no issues in USA and EU.

[@pwhnckexstflajizdryvombqug9042]

Boeing was so greedy that rather than making a successful aircraft and making billions of dollars in profit, they instead chose to make a faulty aircraft and loose 20 billion dollars. Wait a second I don't think it's greed that did that, it's the fact that they didn't consider the consequences of their actions. Everyone seems to think that it's all money money money or human lives. The truth is that if Boeing had done a better job not only would they have made more money, then they did, but they would have not killed a bunch of people too. You might say that Boeing tried to have it's cake and eat it too, get the bigger market share and the big profits, but if they thought they could do that it wasn't because the accountants said so, it's because they didn't think about it hard enough. It's not a case of greed, it's a case of overconfidence.

10:45 - I'm pretty sure the Ethiopian pilots did actually flip the kill switches for the electronic stabiliser trim on the accident flight. However, they left the engines at takeoff power while the aircraft was in a dive, and so the aerodynamic forces on the tail made it impossible to manually crank the stabiliser trim.

B737 check airmen at my company met with the leadership team to give a debrief after meeting with Boeing and looking over the FDR info and CVR transcripts, and they were blunt in their assessment: "We don't want to speak ill of the dead, but any 737 type-rated pilot should have known to hit the trim cutouts and keep them off once the trim runaway occurred from the AOA disagree and MCAS."

The primary reason you have Mcas on this max is because you have different engines (more powerful) and is mounted higher on the wings than your standard B737 is for ground clearance due to size diameter of these engines. mcas was designed to push the nose over to prevent a stall during climb or other stages of flight ,the problem is Boeing built this system with only one sensor to detect angle of attack relative to the airflow over the wing to cut cost and if this sensor fails the aircraft becomes uncontrollable but Boeing never told the pilots about how to correct this situation ,The bottom line is this aircraft should never have been built as this old design 55 plus years trying to work with modern equipment does not cut it

Great video! What kills me is that this system was built to compensate for an intentional design flaw. They could have increased its ground clearance with longer struts, but instead they moved the engines forward and added a system to compensate. It's overengineered. If it was too difficult to increase the plane's height, they could have just come out with a "757X." The original 757 had excellent ground clearance, a good safety record, and is still extremely popular despite being discontinued for almost 20 years.
