The Consequences Of Overlooking Aviation Maintenance And Repair... | Mayday: Science of Disaster

Ya know, the NTSB never explained how the 737 was working well for decades without suffering this rudder issue...and the only conditions it needs to happen is basically just extreme temps?!? How have those conditions not been met to produce this malfunction hundreds of times over???

The duel servo valve also had micro particles of metal in the hydraulic fluid

Aeems best to AVOID all Boeing 737 airplanes?

FBI/FAA/DOT raided Alaska Airlines, and they are STILL in business.

Staggering to believe that you are so worried about staying afloat you'd consider murdering your customers??!!

PAN is s demigod

I learned a lot from the Air Force. Every plane had an OWNER, the Crew Chief. He might only have the rank of an A1C, but not even a full bird colonel could FORCE him to sign off on a RED X.
It is AGAINST MILITARY LAW to fly an airplane with a RED X.
That's the kind of power that Civilian air crew Chiefs should be given over these big airplanes. They need to be protected so that WE'RE all protected.

OMG, you get what you PAY for! 🤦
Don't go ever go CHEAP on those things that are critical to YOUR life.
Discount airline tickets aren't worth the PAPER they're printed on. 😮
Would go to a discount lawyer, or discount surgery center?

Years ago, my firearms instructor told us, "Anything made by the hand if man will ultimately fail". That includes aircraft.

Man, anything, ANYTHING other than a FIRE onboard. 😯😶‍🌫️😖😵‍💫😵

So what’s the $ to human life ratio at ??????

I think they should remove planes and make electromagnetic tunnels across the world it’s safer and faster you know how fast u can propel stuff with an electromagnetic system

I am forever stating how I believe all the 'problems of our world' leads back to someone somewhere cutting corners. Weither a person is a mechanic, a probation officer, a cps official, hotel clerk, court clerk, fast food drive-thru, a janitor, groundskeeper or a bar tender, or a realtor.
What we each do has a ripel effect. Most of which we are blissfully unaware of. While many more of us couldn't care less about a riple effect they cause.
From what I've experienced in the last 15 years, the halfass attitude has gradually evolved from a rare occurrence into the current norm.
So many causes behind this, from the "me-too movement"/sense of entitlement skyrocketing to the absurd, to the lack of any loyalty or appreciation from employers as pay, perks, & benefits have severely plummeted & work loads/ expectations, & costs grow.
Whatever the cause, we all must hold ourselves accountable for everything we do. Certainly when it is our duty, our responsibility- no matter the excuse.
For the record, a pissy attitude isnt an excuse for anything.

Components are supplied by various manufacturers that goes into building an aircraft, and most of these parts can fail anytime.
Just like our automobiles today, aircrafts have sensors for every part that informs you what needs to be changed, It's not just poor maintenance that can bring a plane down.

Yes maintenance did an unforgivable mistake but nobody talked about the design flaw , 😮😮 how you design a very critical system without redundancies ???

Jackscrew grease was 500 hours, saved money going to FIVE TIMES LONGER! WTH Alaska Airlines!

Alaska Airlines lack of grease, and maintenance killed my niece . I will NEVER fly that airline. BTW, those planes still fly as cargo planes, and have had ZERO jackscrew failures.

Considering how many accidents have taken place soon after maintenance due to faulty procedure, there should be mandatory test flights post maintenance. At least then you are sparing the passengers.

Greg Feith is so handsome. And his sexy voice makes me weak. 😘😘😘❤️❤️❤️

The reason why I watch these aircrash investigations is because of the voice of this guy explaining this documentary, wow

Many years ago the Brazilian soccer team plane crash was due to pilot skimping on fuel. It ran out. Pilot was part owner of janky airline and was trying to save money.

Your plane is only as safe as the worst unqualified, corner-cutter mechanic that worked on it. Lying about repairs, not following Boeing directives.
Alaska Airlines...Grease is too expensive, and jack-screws are too hard to reach. We saved money!

Not throwing shade, just an observation, but it seems in every single one of these videos there is someone with a speech impediment. Its as if there is a requirement for a mayday video.

cause of death: capitalism.

I can't believe the twa from final destination it was based on a real flight 😢

One of the best episodes imo

I work with a gentleman who retired from aviation maintenance and I never met a more detail oriented person who’s not happy unless every aspect of his job is done methodically and per routine.

An "A" check is not a simple walk-around. That's one of the "line checks". A checks are extensive visual inspections of the areas not visible during line checks, including the top of tge fuselage, empennage, and top of wings.
C checks do not take hundreds of hours. They take thousands of hours involving dozens of specialists working on various areas at the same time, and take up to 2 weeks weeks of hangar time. They cannot be done in one night.

It is not a good idea and looks dangerous that they do the inspection during the night. What kind of people can do proper judgement during the night shift.

“when a new component is installed into an older airplane.” The Swiss Air flight 111 was a 7 year old MD-11. That’s not an “older” aircraft.

Big boss: let's save few pennies by cutting hours from worker, we gonna be moar rich

Airplane: im worth millions dollars.

Passenger: rip ⚰️

I worked for an aerospace company that provides parts for Pratt and Whitney, RR, and GE. The company cuts so many corners that I could write a book with all of the company mis conduct

no Jal 123 was a very craply repair job by Boeing

There is a saying: "Every regulation is written in blood." This is why I despise politicians who promise to end "profit-killing regulations." Those regulations exist BECAUSE PEOPLE DIED.

Cheaper "off grid" parts are a problem.

It's too bad we don't investigate other accidents like we do planes. 😢😢

Licenced aircraft mechanic here; There is a big disconnect between manufacturers of new and old technologies that makes it surprisingly difficult to learn how systems work.
Struggling to learn- RR

I find that Southwest Airlines seems to be the most open to the media, good and bad press coverage. I like that, and fly Southwest.

Any machine wih moving parts need to be maintained whether "management (? or better mismanagement)" likes or not. Its not a matter of desired best etc. but matter of people's life, plus much more. Those who want minimum maintaince and high performance are in dreamland. Turbines are high maintainence equipment and must be regularly inspected, checked. plus there are other hydraulics and equipments which too need to be attended to giving "Maintainence Departments" sufficient time and resources.

Your headline is misleading. Only one of these disasters were due to faulty maintenance. Design flaws and/or procedural errors, maybe, but not errors of maintenance personnel. Even the prop guy was following the procedures he was taught, and using the equipment he was given to use. The one POSSIBLE exception is the bulkhead repair that eventually blew off the tail.

RETIRED MSGT USAF, JET FIGHTER MAINTENANCE MAN.

I was living in El Segundo, a couple of miles south of LAX at the time of the accident and remember the mass of helicopters hovering over the ocean, wondering what was going on, then the sadness and frustration when everyone found out what happened and most importantly WHY - other case of corporate GREED as usual- I can't believe that Alaska Airlines is still operating-

67 w

This is true. One of my parents' friends died on AA 191 where there were shortcuts made in engine/phylon removal and reattachment during its "C" check in Tulsa to save money but it cost lives. And the "C" check caused the problem rather than discovering a previously unknown one. They had to ground the fleet of DC-10s b/c other airlines besides American Airlines were taking similar shortcuts.

UNITED 585 IN COLORADO...WAS SAID TO B PIOLET ERROR....IN REALITTY...THE PIOLET AND CO-PIOLET WERE A COUPLE MALE AND FEMALE..... ARGUMENTS BACK AND FORTH WERE ON THE VOICE RECORDER....BUT WERE TOLD SOMETHING ELSE AND NO VOICE RECORDINGS ARE MADE PUBLIC......JOHN LEAR CONFIRMED THIS.....IM JUST SAYING.....THE PUBLIC IS TOLD A STORY.....

It makes me sad to hear the technician's regret in regards to the propeller. There was a hole in his training, and the equipment he was given to use was ill-suited to the task. I can't imagine how I'd feel, but even though it's his initials on the paper, I feel like he had a minimal amount of fault. You can't fix what you don't know is wrong.

Absolutely incredible how these engineers can figure it out

isn't the JAL repair work follow CLOSE AND DETAILED procedures ?
Everything to the letter from the manufacturer.

I don't fly. I haven't been on a plane since 1976. (I was 11 years old, I didn't know any better, and I didn't really have a choice.) It was an Eastern Airlines DC10, and it didn't crash. It landed safely in Florida. Haven't flown since. I have a truck.

Remember both space shuttles that blew up in the air 14 people died in both space shuttles that took of and both space shuttles blew up in the air how com e you people don't talk about the space shuttles
