The Questionable Engineering of the 737 Max

How do I make my dog loyal to me?

Its people given a job to do correctly and they not doing it for what ever reason, what idiot takes door plug loose to fix a seal and does not put the bolts back in that hold the damn door plug inplace ???? MY gawd have people become so lackadaisical they can not do a simple job ???? Where was the inspection of the repair,?????? Who signed off that repair as being done, and why, did he even check it ????? Hard questions that need true honest answer and that inspection proceedure changed !!!

how can we be sure that 777X is safe too? If it can happen to the Max, then it is not a zero chance that the same thing could happen to the coming-soon 777X right?

Why are only the winglets and the last part of the rudder painted with airline liverlies on thos semi-raw planes?

Well, they are made by Spirit Airlines. Obviously they will be low quality.

It's so frustrating to see Boeing continuing to put people at risk without any real consequences. The government needs to require more regulation since they clearly can't be trusted to do it themselves.

The most expensive airplane you can make is one that crashes. If you cut to many corners while making a square, you end up with a circle

So much for "if it ain't a Boeing, we ain't going". Brian should switch it to "if it's a Boeing, we ain't going"

The 737 Max is the Ford Pinto of airliners. I'd rather drive than fly on one.

No bolts were installed after maintenance by Sprit after Boeing found a seal problem. Spirit's fixers at Redmond repaired it, but they didn't reinstall the bolts, and no one inspected the work.

Reminds me of Boeing's response to the 737 issues in the 90s. They knew, then, and simply lied about it.

DEI problems. Maybe next time hire back some old white male engineers to over see the Equity hires, it seems they knew what they were doing.

They are more worried about their DEI score and funding the Lgbtqrstuvwxyz over passanger safety

bad thing happens in very highly regulated industry "WE NEED MORE REGULATION"

Counterfeit bolts?

1st fix would be adding a longer struts , drop the engines back under the wing
2nd fix would to be re-engineer the door plug

Holy fuck do I hate capitalism

So once the business morons at McDonnell Douglas bought Boeing using Boeing's money they brought in James McNerney and told him to stop concentrating so much on safety and increase profits for shareholders and bigger bonuses for executives. He subcontracted everything possible and tried to destroy the machinists union by building a new plant in non-union South Carolina. He retired after 10 years just as the Max was coming into service. Mullenburg just maintained the cultural shift. He got blamed for something that started before him but he also did nothing to correct it. But his Golden Parachute was an insult. He and Boeing should have been criminally liable for those crashes. They are also a key Defense aerospace contractor and that culture exists everywhere in corporate America, which is why our defense establishment is so defective. The best thing would be to pass legislation reforming the FAA so they aren't controlled by the aerospace corporations and airlines(regulatory capture) anymore. Then require the FAA to assume oversight of Boeing and force the company to make the necessary changes in corporate culture on the grounds of public safety and national security. Of course, I think we need legislation limiting executive compensation to a fixed ratio of employee pay. And tax codes that limit shareholder profit to 10% per year with any surplus put back into development of the company. Plus a prohibition on stock buybacks.

Once again Boeing's shitty management wants to bypass safety and there should no bypass allowed.

I guarantee die-versity had something to do with it. This is the result of quota hires.

boeing is toats. they lie, lie an lie. airbus <3

This is why MBAs cant run tech companies

They got the exception!

I was on a Boeing 737 Max exactly one week before the accident and I was flying on the same route.

There is a solution, make installation of ALL components follow a checklist, not just doors, but ALL components, checklist should have all steps detailed in sequence, test and double check each step.

Making an inherently unstable aircraft design flyable by the use of software, is a great way of producing highly agile combat aircraft. However it should have absolutely no place in a civil aircraft!

Loved the Scream!

did you really just use the Wilhelm scream.... You put all that time and effort into your vids, and then use the Wilhelm scream. Got tired and decided to have lazy moment?

50% of the video is Nebula bs advertisement. Do not waste your time.

It is so important to have a workplace culture that encourages speaking up about safety and quality. I recently told my management that safety issues were being ignored, and they recommended I find a different job! 😢

It's crossed my mind that this could be intentional, but then what purpose would it serve in the greater scheme of things.

I’ve heard from a licensed 737 engineer that the plug is a proper door plug. The emergency exit hinges are at the bottom and the plug has the same hinges. If the hinge bolts aren’t secured or come undone then the door can move upwards so that the fuselage and door pins no longer line up and the door will then blow out with little damage. Other exit and plug loose bolts have been found. Boeing used to be well built but that cost money.

What Boeing has going for them, and they probably know this is there is a 5+ year waiting list for Commercial Jets and there are only two companies making them. Boeing and Airbus. You leave Boeing, you go to the end of the line at Airbus.

Wilhelm scream 😂 😉

When the Challenger disaster killed 7 people the govt pulled together a team of the country's top scientists to investigate NASA and it's contractors from head to toe to find the problems, both technical and systemic.....over 300 people have now died on Boeing aircraft due to what should have been easily preventable circumstances (now apparently we've been lucky that number hasn't risen since the MCAS incidents) and there has been very little if any discussion of a systemic investigation of Boeing's commercial aviation ecosystem (ie of Boeing itself and all its sub contractors). This is madness. Firing executives is not a long term solution ffs!

"CEO...Fired with a $62M golden parachute"

Amazing analysis as always! And your video quality has gotten phenomenal of the years! One quick, but important note about bolt lock wire.

It DOES NOT prevent a bolt from loosening from its set torque or rotating entirely loose so it can freely spin (though if it does rotate that loose the lockwire was still probably installed wrong).

It DOES prevent it from completely disassembling and becoming loose debris inside of the airframe. i.e. Lock wire is not a anti-vibration failure prevention mechanism, just a FOD prevention mechanism.

The lock/castle nuts and bolt adhesives you mentioned though are indeed useful for vibration failure prevention.

Does this still have the Mcas

Former Boeing employee - worked 8 years as an engineer in BDS from 2014-2022.

You make excellent points and explanations, but the one thing that I strongly disagree with was that the 737 Max program issues had anything to do with Dennis Muilenburg.

When Muilenburg took over as CEO, he pushed for changes in quality and safety which, had they been adopted decades ago, would have avoided these fiascos.

He was not CEO during a majority of the development of the 737 Max. He was handed this flaming pile of garbage, by the previous CEO James McNerney, who the 737 Max program was developed under. Muilenberg did his best to clean it up, but the damage was already long done and shareholders wanted to see someone fall to take the blame.

My personal theory is that James McNerney knew about all this, and intentionally left before disaster struck.


Side note, I can also confirm most of the comments about poor management, ridiculous bureaucracy, and focus on schedule over safety that happens there.

At least one airframe and power plant mechanic and pilot has gone on record as saying the seat at the blown plug door,was vacant at the time of incident. The shirt story may likely be a myth, as much loose in-cabin material vanished. Also the door to the flight deck was never breached, as had once been rumored.

The root cause is WOKEISM

It's the same door plug that's on the NG fleet that's had no issues since 2007.

*cotter pin

Leave Boeing wat about air bus planes ending catching fire and DC 10 as long as humans there wil always be the human factor and as for air Alaska they had poor mataince on the jack screw

I dont think the 737-9 max or w.e they are calling is cursed, Boeing is the curse by micro managing and putting profits before quality all so the guys upstairs get their big fat checks quite simple IMO its all just GREED! 30 years ago Boeing was a top tier aircraft company the current generation of upper management was given a ferrari and treated it like a lawn mower

Can't wait for fully electric planes.
Because of the "green" obsession.
I'm sure they're not being pushed because of greed.
It's to save Greta's penguins. Or whales. Or something.

the real question all of us should be asking is, why are companies skipping the extra door? whats wrong with just completing the plane as necessary?

I loathe these jets. I've worked on E3s which are basically 737s with radars on top... they're all decrepit and falling apart
