The real reason Boeing's new plane crashed twice

This isn’t just a computer bug. It’s a scandal.
Join the Video Lab!
Two Boeing airplanes have fallen out of the air and crashed in the past six months. On the surface, this is a technical failure. But the real story is about a company's desire to beat their rival.

      +Brian Dell Bottom line is that Boeing put a system in a plane to address an inherent misbalance in the flight characteristics of the plane in order to sell the plane as just another 737. In order sell this idea this they completely omitted mention of the MCAS system in the flight manuals. This would have been fine if the system didn't have absolute authority over the stab trim and pitch of the aircraft but it did! It would have also been fine if the system had any degree of redundancy... Which it didn't. It may have also been fine if the pilot input had control authority over MCAS... But it didn't! This is pure speculation but imagine you are a pilot and you lost complete pitch control of the aircraft and it is nosing down. You have seconds to figure out a problem that is not even mentioned in the flight manual and you are at a low altitude trying to make it back o the airport for an emergency landing. That's like telling a trained UFC fighter that he should have used his Jiu-Jitsu skills when someone came up behind him at a bar and sucker punched him in the back of the head. Never saw it coming. Another thing to mention is that because of the jack screw design of the 737 turning off MCAS by activating the cutout switches does not automatically fix the issue... The Stab trim is now STLL in FULL nose down position because it cuts power in the last known position of the stabilizer which in this case was full nose down! Now by following Boeings instructions you have created a stabilizer that is STUCK in full NOSE Down. This stabilizer now needs to be manually BY HAND trimmed with zero assistance from the electric motors which could be impossible in the current situation.

      +Rob Y The system was off before that happened. So, no, the system did not do that. They turned it back on despite instructions not to. And then bad things happened because they were exceeding the aircraft's speed capacity. Never once did they try to slow down. Boeing cannot design a plane that is controllable at 500 knots because of this thing called physics.

      +Brian Dell Boeing created a system that had NO redundancy for sensor failure that had absolute trim and pitch control over the airplane. Then didn't tell the pilots about it because they wanted to sell the fallacy that the Max 8 was just another 737. I guess the pilots could have slowed down but they forgot to turn on the antigravity switch as they were struggling with a 40 degree nosedive that the non redundant, ghost system put them in.

    Lovely anti-American sentiment again in this biased piece of, well for brevity's sake lets call it reporting. Lets not forget that Airbus had major issues with their A320 Neo aircraft - the culprit? You guessed it, its engines. Though the reasons differed, production was still halted and aircraft deliveries were postponed costing airliners a lot of money, but that's aviation, however, isn't it funny how Europe or Airbus gets no bad press? And if anyone thinks that Airbus didn't skip and cut a few corners to save lives, well wrong. Air France flight 447 could actually have been averted if Airbus would have taken the warnings seriously after other Airbus A330 aircraft suffered similar icing conditions which resulted in the pitot tubes getting clogged resulting in the autopilot disengaging involuntarily. Then Germanwings flight 9525 - official story suicide by co-pilot - though other likely theories such as pilots having flown the same route with the same type of aircraft - an A320 - reported sudden autopilot override where the pilots had no control over the aircraft neither via autopilot input or manual flight, the only reason why nothing happened is because the captain pulled the circuit breaker of the anti-stall system and thus regained control. In short, both aircraft manufacturers are under immense pressure to deliver equipment that is never allowed to fail and are subjected to immense stress on the airframe which few understand, and considering how few fatal airplane crashes occur with an estimated 102'000 flights per day is truly an accomplishment and deserves nothing but the highest praise for the engineers, pilots, cabin crew, mechanics and the entire industry that keeps all these flights as well as entire economies afloat. And honoustly, does anyone really think that Boeing and Airbus are there to make a quick buck and jeopardize potentially their entire workforce? Why bother engineering and improving at all when your goal would be to crash it anyway? This type of liberal saloon communist propaganda only appeals to the feeble minded. Those who have lived - myself included - in socialist/ communist hell know to appreciate everything that comes standard in the greatest country in the world - don't like it, go live in Venezuela or N. Korea.

    ... I do not justify Boeing for the serious error of the Mcas system which could have managed to correct the problem in the 2 accidents caused but being something badly thought and in this commercial war the opportunity is taken to make firewood of the fallen tree ... It is not the first time that these problems occur in the development of a new or an evolution of an airplane in production, of course, it is an evolution but each new accessory or re design in wings, body or avionics system implies changes that seek more efficiency or get more out of a proven base since it saves millions in making one out of nothing ... the 737 has proven to be one of the most efficient and safest in the world, because since the late 60s more than 10,000 units and has projected more than 4,000 to deliver and build. This has become a scandal, especially for those who have interest that this plane has stumbling blocks to continue selling their products in the aircraft market between 150 and 200 seats and this I say especially for the Chinese and Russians with their joint venture CR929, they were the first to paralyze their fleet ... I hope I'm wrong Show less RESPOND

    Wait. Boeing - just for promotional reasons - had lied about unchanged flying characteristcs, and then omitted the existence of MCAS in this "tablet-training" procedure. That's right, good point. But isn't it secondary to that MCAS had failed, repeatedly? And I remember news about simple error in MCAS design, saying that data were read from only one of two redundant sensors, making whole MCAS fully dependant on proper working of one device, and unable to cross-check it in case of its failure. What about it, is it unconfirmed? Existence of two sensors points that it was not just a cost cutting, so there stands question about the procedures, about checking and controlling the design. How has it happen that not Boeing nor NTSB had noticed that ?

What actually killed 346 people is MONEY. Boeing even if you manage to 'fix' this plane, your credibility can't be fixed so easily. And I really hope that whoever put the stamp of approval on the Max 8 will be prosecuted.

    So what's the connection between the new engines and MCAS pushing the nose down? I can't see the connection through this video. If you mean the engine is physically heavier, that moves the CofG forward all else equal - no issue - you shouldn't have seen a crash like this; new engine having higher thrust causing a pitch-up at max thrust? Then have a slightly larger horizontal stabiliser - it's not rocket science to solve an issue like that AND still keep the resulting handling characteristics very close to the the 737NG, and I mean mechanically without adding electronic augmentations - even the NG had -700, -800, -900 variants all sharing the same type rating. The Max has had tens of thousands of flight hours logged already. If the issue is fundamental in the flight mechanics, as this video suggested, it would have shown up a long time ago, and it wouldn't have manifested they way it did - two planes just suddenly decided to do kamikaze dives. Airbus has had its "alpha floor" flight augmentation system for decades. Much more likely, Boeing simply screwed up trying to match.

    I'm dubious about the change in engine positioning contributing to pitch up issues, given that a lower mounted engine would have a thrust line with a greater moment-arm over the centre of pressure (airframe drag) and centre of mass. Perhaps if there was a change in the vertical inclination of the thrust line, or significantly greater thrust with the new engines. Do you have any evidence to confirm that the MCAS system was introduced specifically to mitigate pitch-up issues caused by the new engines, of is this speculation?
