Following the catastrophe of Lion Air flight 610, the last thing Boeing would have wanted was another fatal incident involving one of their new 737 MAX aircraft. Sadly, this is exactly what came just months later with the tragic crash of Ethiopian Airlines Flight 302.

But just like the Lion Air flight that came before it, the case of Ethiopian 302 is widely misreported and misunderstood. The much vilified MCAS certainly played its part in this crash too, but upon close inspection of the final report, it's also clear that some key decisions at Boeing put these pilots and passengers in unnecessary danger.

In today's video, we take a closer look at what happened on Ethiopian Airlines Flight 302 and how it changed aviation forever.

@DAOzz83 - 2024-12-29

The stabilizer is very powerful, and therefore large, sudden movements of it can easily induce an upset (as we see at the end of this very video!). Therefore, pilots are trained to use their trim buttons only in extreme moderation. It would go against everything he had been taught about trimming for the captain to jam his finger onto “nose-up” and leave it there for twenty seconds. Given a little more time or fewer distractions, it’s possible that he could have realized that this was necessary. But while acting on instinct and habit, it’s just not something pilots do.

@@supremelord8605 well you have to take into account the situation they were in. SO many things were happening at once and they likely didn't even understand at the time that the Electrical trim input that they were inputting did basically nothing because MCAS was way more powerful and faster.

I am a cabin crew and I was flying in MAX in between those two accidents. I wasn't (and many of my colleagues) too happy about it because a) we were primarily on airbus and b) the Lion Air accident wasn't really solved in my opinion. So when I was scheduled on MAX flight, after the briefing I asked our captain what did he think about the accident and MAX and he said and I'm quoting: "It was a crew mistake, we are better trained, so don't worry about it." Two days later this accident happened and they grounded MAX's and I'm not kidding when I say every single one of my collegues (possibly all over the world) had the same thought: This could've been me.

I think the end of this video hits the nail on the head. MCAS was never a needed system for safety. The function of MCAS is for Boeing's bottom line, trying to quick fix a losing battle against their rival. In a perfect world it would never exist and Boeing would develop the true next generation of aircraft instead. Even if the problem is now fixed, a lot of people are scared to fly in Boeing aircraft because of the sloppiness they showed in the MCAS example. And I must admit I also feel uneasy thinking about how they cut corners that should have never been cut.

You should check out his Mentour Now! videos on the Airbus A220! Especially the one entitled "Did Boeing give Airbus a free airplane?"
Boeing actually had the opportunity to buy a stake in the A220 when it was the Bombardier C-Series, which could've been the plane they needed to compete with the A320neo, which was the only reason they built the MAX to begin with.
BUT instead of buying it they tried to kill it with a bogus trade complaint and got tariffs imposed on the C-Series after Delta Airlines decided to order the C-Series instead of the MAX. Bombardier actually offered Boeing a chance to buy a share of the C-Series program again at that point, but they turned it down. The sanctions against Bombardier ended up getting overturned, Boeing lost a contract to sell F-18s to the Canadian government, Airbus ended up buying the C-Series for $1 and Boeing ended up putting out an inferior plane... that caused these crashes, all because they preferred to cut corners and do things cheaply than spend money on a good plane. And that's going to keep biting their butts for years

@stormix5755 - 2024-12-29

As a programmer, the fact that the computer systems didn’t immediately disable MCAS, the autopilot, and the stick shaker as well as all the safety protections when the AOA sensor disagree malfunction happened is baffling. If the sensors don’t agree then all of those systems aren’t just useless, they’re dangerous.

So many of these accidents are caused by automation taking cues from faulty sensors. It shouldn’t be completely on the pilots to decide what to do in a vague situation like this while simultaneously trying to figure out which systems have gone wrong. At the first moment of disagreement, have all automations shut off and have “direct law” to use airbus speak, apply. Manual controls only for all systems. An aircraft taking all automation away is less scary than a phantom problem that cannot be diagnosed while the aircraft is moving weirdly

@axelBr1 - 2024-12-29

I work in the Oil & Gas and chemicals industries and worked with the control and emergency shutdown systems used. All ESD systems use 2 out of 3 voting for sensor inputs; control and ESD systems can detect when signals are out of range and flag them as faulty; the development of smart sensors that can diagnose faults; operators are able to over-ride faulty signals. This means the control and safety systems remain functional when there are sensor failures.

@joekelly7505 - 2024-12-29

I just made the same comment a few minutes ago. Baffling indeed. Boeing put their own dubious interests above public safety.

@michaelhansen7516 - 2024-12-29

But there's only one sensor active at a time. The algorithm alternates on different flights. So there's nothing to disagree with, unless you mean that the program should disable MCAS if the sensor gives a nonsense reading. Another fatal flaw is that the program had no limit to how far and how long it would command the stabilizer trim to keep going until it reached obviously deadly nose down angles. Just a dumbfounding program. Unbelievably dangerous.

@christianchristiansen99 - 2024-12-29

I have the same background and commented basically the same thing when Petter released his first videos on this a couple of years ago. In critical systems like this, 2 is 1, 1 is none. Of course, an airplane manufacturer like Boeing knows this, which made it even more baffling..
However, in lieu of the revelations of questionable quality control etc. throughout the organization which has come to light since then, it doesn’t really surprise as much.

@jodi_kreiner - 2024-12-29

one of the things that always gets me, is that they are obviously getting the “too low, terrain” warning, but not a single person at boeing thought to tie that into MCAS and make sure that it stopped pitching down if it sensed that the aircraft was too low. like I get that it was often used at takeoff when the altitudes were already low, but I feel like if you already have the radar and positioning sensors that can warn you about altitude, it shouldn’t be that hard to write a line of code in the MCAS that would disable it in the case of another one of those warnings. seems like a “terrain” (i.e. you’re about to crash the goddamn plane) warning should supersede any of the other automated systems that may be providing pitch down input…

it also makes my blood boil that MCAS was literally only supposed to provide simuLATED YOLK FORCE so the aircraft “felt” like the old 737s to handle. at what point does it make ANY sense to give a system designed simply to make a pilot feel more comfortable the ability to catastrophically control the aircraft, ESPECIALLY when its signals are based on a single point failure ?!? like good lord… I work in aerospace & defense for a direct competitor to boeing, and there are DOZENS of levels of checks & balances to ensure that no mission-critical function can ever operate on a single point failure. I’m so heartbroken for what all these pilots, passengers, and crew had to deal with because of boeing’s greed, ignorance, and megalomania.

Isnt that insane? How did Boeing even think someone could land an aircraft, that freaks out when the autopilot is disengaged? They created a dilemma instead of a solution and that should have been clear right away. Also, that they obviously didnt even try out in a simulator what happens when the trim is already way down and stab trim gets turned off shows the arrogance involved.

And so they conveniently "forgot" catastrophic factors such as "the fucking system resets when it's trimmed so it'll continually re-engage," "the issue with the AOA sensor means MCAS will always activate alongside a slew of other failures that need prioritizing as well," "the runaway stabilizer procedure wouldn't be defaulted to when MCAS does not act like a runaway stabilizer," "pilots that do not know MCAS exists will not be able to respond in a fast and appropriate manner," and this one, "autopilot will disengage when the broken AOA sensor causes seven different failures in the span on 30 seconds."

@biosparkles9442 - 2025-03-30

@ on the "the runaway stabilizer procedure wouldn't be defaulted to when MCAS does not act like a runaway stabilizer" note; internal Boeing documents that were released (leaked, maybe?) showed that they actually did expect pilots to respond to erroneous MCAS activation as if it were a runaway trim scenario. Then, after the Lion Air crash, Boeing released a pilot bulletin stating that the runaway trim procedure should be a memory item (a not-so-subtle way of saying that the Lion Air crash was caused by poor pilot training and not by their murderous plane).

They really thought pilots would treat MCAS activating for no fkn reason, over and over again, as if it were a runaway trim situation, despite it not behaving anything like said situation. It was straight up criminal negligence and it boils my blood to this day that not one person from Boeing was held criminally responsible for the deaths of 349 people.

In the beginning I was one of the people that believed that although boeing was negligent for not mentioning MCAS to the crew, the crews were still wholeheartedly responsibile and the crashes could have been avoided. That was my assessment as a general aviation pilot proceeding to the airlines. Listening to famed NTSB investigator Greg Feith analyze the facts and come to the same conclusion helped solidify my thoughts.

Your coverage of both accidents proves that there is so much more to the story than I, someone who thought they knew the facts, actually knew and understood.

I have since changed my mind after watching both videos and although i still think the crew could have done better in certain areas, at the end of the day, it was actually an incredibly hard scenario and not as simple as flipping the cutout switches which is what i initially thought.

The real blame falls on the hands of the FFA, that approved (certified) this airframe. A single point failure should never be approved at this level of control. Boeing is also at fault for promoting a design with a single point failure.

@MrNicoJac - 2025-01-02

It is commendable that you admit your mistakes - that's the best defense against arrogance taking hold over your mind :)

After watching this video, I know that the pilots could have saved the plane.
But only if they had known exactly what to do, which was impossible.

It would have been insanely unrealistic to flip that switch back on and trim up continously for maybe a full minute non-stop (or even more!), while visually verifying he trim setting slowly returning to normal, and then flipping the switch back off when the plane was in trim again.

That's the only way I can see out of this situation....

But anyone thinking sooooo far out of the box would be nothing but a total hazard in literally every other situation, so they should never make it through flight school in the first place 🥲

@ysw8291  Out of all the people in the aviation community, you are the type of person who pisses me off the most. I myself am a "colored" pilot, so maybe I should go out there and do something reckless because, hey you know what, I'm colored and I can do no wrong 😁.

If you read my comment fully you would have seen that I have changed my mind and no longer blame the pilots for the crashes. PILOTS, not colored pilots.

In crash investigation pilot's are judged by their actions and perhaphs prior training and history, but not by their color. I explained that after analyzing the facts and reading the actual crash reports, I initially thought the pilots were at fault. After seeing the full picture, I no longer think so.

Safety has no color, risk management has no color, and good aeronautical decision-making has no color. If YOU think that color makes a difference, maybe YOU should check yourself and take your racism elsewhere.

All they needed was a simple switch, MCAS on or off. As well as avoiding the accidents, pilots would most likely only used MCAS until they got used to the slightly different characteristics of the revised aircraft.
Calling Boeing a bunch of clowns is an understatement. I wonder whether the designer of MCAS had designed anything more than computer games in the past, where the reset button gave him another life.

The thing is the pilot trim switch would always override it anyway so it shouldn't matter but for one reason or another, training, muscle memory or whatever, they would just never do so more than a couple seconds. Far too little to counteract and usually not even in time to interrupt the MCAS input.
