- Two US airlines say they have found issues with door bolts on their Boeing 737 MAX 9 jets.
Alaska and United Airlines said they had discovered "loose hardware" on their fleet of airliners.
The findings come after the Federal Aviation Administration grounded all 171 of the 737 MAX 9 planes operated by US airlines after a window and chunk of fuselage blew out of one Alaska Airlines aircraft shortly after it took off from an airport in Portland, Oregon.

What broke? It is Boeing that is broke. I am ashamed to say that I was part of the 737 Max, Flight Test program.
sorry for the trauma
It’s okay buddy
37 years at Boeing I am also ashamed !
Pretty sure it’s Boeing administration’s fault in thinking only of stockholders short term gain.
Is 787 any better?
I have a scheduled flight 😌
As a former (UK) aircraft stress engineer, "loose bolts" suggests to me that maybe repeated pressure/depressurization caused the (aluminium) material underneath the bolt head and the nut to deformed enough such that all the (very small) bolt stretch that made the bolts tight in the first place disappeared. That would be a design error.
It's poor reporting gone viral (not your assessment or anything, it's good). In this case the bolts are only in a lightly loaded shear application with castle nuts and cotter pins, so it doesn't matter if they're loose. They just position the plug in place against structural. What does matter is if some dudes forgot to install them, which is what the NTSB is hinting at. They had a very good assessment yesterday at their last press conference.
Is it common for planes to have a door plug or is it just specific to the max 9?
In the democratic era, when engineers were in the design making seats, such a plane would never roll out of the factory. Thanks to aviation sector fascism in the US, there's no alternative, so whatever a monopolist produces, it would be accepted. In the democratic era, the world witnessed how McDonell Doughlas was removed from the market. But in the post truth era, McDonell Doughlas is the only choice.
@@adam7349 It is common and is a proven design. The NTSB hinted in their report that the bolts may not have "existed". Whoever did the installation and whoever signed off the closing inspection likely screwed it up, but we shall see after the investigation is over.
OK, now I've seen the installation, how about standard bolts (not cross-drilled) having been used - and the nuts just being done up "tight". In that case no design error - but it would be a near criminal manufacturing error.@@modelenginerding6996
Definitely not flying on the max now .
max nah
Or Boeing. Made in USA
From the Opioid crisis to oil spills, Boeing's lack of quality planes to GFC, it's clear that American regulatory agencies have crumbled. Just like any third world country corporations can pay their wayout of criminal actions.
In fact if they are smart about it they can have government bail them out . Keep the profits and externalism costs.
I encourage everyone to stop flying on Boeing.
This is just one of an endless stream of quality problems which have now been going on for many years
There will be be more fatal accidents (as this well could have been)
Boeing is addicted to corner cutting and quality inspections in the name of profit.
Then everyone should be encouraged to stop flying on Airbus
Quality problems will just hit them as they are getting supplier issues and then it will lead onto quality problems on their behalf.
Which fatal accidents will there be?
Airbus is also addicted to corner cutting and quality inspections in the name of profit
@@nickolliver3021
Why Airbus? They haven't been endangering and outright killing 100s of people.
Have I been missing out on some news?
If it's Boeing..
I 'aint going...
To be fair I can't afford to go Ford anywhere... either...😂
take an airbus
@@jojothetasmaniansassmonkey8866 they are not good either
@@nickolliver3021 For passengers, I say their quite good honestly, depends on the airline though.
@@mubassirzaman7202 even the boeings are too. Many still just go on boeing flights without hesitation
This makes me so angry, as a former naval aviation maintainer, every single piece of work we did on aircraft had to be done in accordance with written flight procedures publications directives checklists and signed off by a supervisor and then, QAed and CDI,Ed before the aircraft could be deemed safe for flight. A modification to such a new aircraft like a plug needs to be manufactured structurally designed and approved,I including the bolts, which I'm sure are going to be NDI,ed. Some body thought this was a good idea, they were wrong. Were the bolts part of a pre flight inspection? Probably not from the flight attendants responsibility, like a normal door would be. So if was just a door in the first place there never would have been any problem. The good thing about this mishap is the finding of other problems which probably saved lives. GO BACK TO USING THE DOORS BOIENG!!! Problem solved.
No one sells more Airbuses than Boeing. Hopefully Airbus cut them that bonus check.
Clever clever
Better check the bolts on the Boeing Starliner
Boeing has been having these issues for decades now, so no surprise. Would advise people to watch the Aljazeera doc on the Boeing 787 dreamliner lolol. Its just business as usual for the bean counters.
Why should they watch the Aljazeera doc. that dates back to 2010/11
Shame on Boeing
shame on the world
Is it a pursuit of profits and shareholder dividends over safety?
it is... wait until 777X comes with its "foldable wings"... which is a travesty, they will 100% cause a crash with that.
Pretty much, yes. When Boeing acquired McDonnell-Douglas in 1997, the McD-D corporate culture infected Boeing. The former CEO of McDonnell-Douglas - the guy who had run that company into the ground - later became CEO of Boeing; he said he wanted to change Boeing "So it's run like a business rather than a great engineering firm".
@@bilgsl3830 how would they cause a crash with the folding wingtip design?
@@nickolliver3021 wait until those hinges shear off, or the pilots make an error and take off with the wingtips still folded. All to satisfy some rich sheik owners of gulf airlines whose fixation on profits above all else, required this kind of design in the end.
0:49 that woman talks like her previous job was a grocery store manager… I can t get over how she announced that they found the door, totally unprofessional and foolish appearance for the seriousness of this incident.
well in the great US and A quotas matter more than who is the most qualified for the job
I always knew AA was suspect after the flight 261 crash back in 2000, due the jackscrews not being inspected, nor greased.
Their motto is, save money, at all costs.
Lmao! How is that on Alaska Airlines? This is clearly a manufacturering issue
AA doesn’t even have this model in their fleet right now so how is that relevant
This isn't a maintenance issue. The aircraft was brand new, the door plug shouldn't even need to be looked at for years at a time. All signs point to poor quality control at Boeing.
@@chrislee7532 this is always well greased when we look at it,
let run them longer and get more flights
@@Werrf1 we its the Airlines that bring in decorator companies to put their interior in
also there is an inspection where plane is gutted c or d check
The Biggest problem is that planes are now like Android phones they do so many stuff well except make and receive a clear phone calls 😅
To prove my point l don't mind a $300 Android phone however give me a $10 phone dedicated only for phone calls for my emergency lol
it's embarrassing how the two FAA guys are shown just standing the door up on it's side. Possibly interfering with evidence existing on the surfaces of the area they just rubbed into the dirt.
The door was found in trees not on the ground. FAA did investigation with door in the trees and once they were done they removed it from the trees.
Yeah because falling from 16k feet would have damaged anything
Airbus. 💪🏾
The 737 max is dead
And a lot if people with it
@@haiwatigere6202 true🤗
and so will airbus be
@@nickolliver3021 no airbus is going on and doesn't hide information like boeing did on mcas.....
Boeing is now a wall street bankers company not engineer and mechanical technicians company
Mcas....bolt...door ....nuts...
What else ?
Outrageous that the failed door plug would be caused by MISSING bolts. However, the accusations of "loose" bolts sounds suspiciously political. All the detailed info shows that the bolts do not need to be torqued because they are merely like a padlock, which can be "loose" as long as it stops movement of a latch. These bolts cannot continue to loosen because they have castellated nuts with a pin that prevents the nut from turning.
Surely this isnt due to the design but rather poor maintenance.
The airframes are delivered to Boeing by another company, with Boeing performing the FAL (final assembly line) tasks, such as fitting the interior per the customer's requirements. This involves removing the plug door and reinstalling it afterwards. Four bolts secure the door, with a security wire wrapped around these special bolts to keep them from backing out, which is apparently what happened here.
Everything looks like someone at the Boeing factory didn't reinstall these bolts properly, which allowed them to slowly work their way out over the course of the flights in the weeks before the accident. Since the same issue was found on other airplanes, that means that it's a systematic issue, and yet it passes through the QA step, with every supervisor signing off on the task. Which is extremely worrying.
This has nothing to do with maintenance.
The airplane was brand new so no maintenance had been done around the fuselage yet.
This is another proof of the incompetence of Boeing. They simply don't care about quality as long as they can generate profit for their shareholders and since it is America, nobody ever goes to jail, even if people get killed because of the criminal behavior of Boeing. They just pay their way out of trouble all the time.
That's the American culture. Only money matters.
The Hawaiian Airlines plane was brand new, a few weeks old with very few flights.
DOOR PLUG This option is only available on the -9 and limits the maximum capacity to 189. The door structure is modified so the sidewall does not infringe into the interior and a row of standard seats can be installed. A full-sized window is also installed. Boeing warns that future activation of the mid-cabin emergency exit doors will involve significant cost and therefor to consider retaining the baseline configuration with deactivated mid-cabin exit doors if future activation of the mid-cabin exit doors is required. AA went with the door plug, against Boeing recommendations, and I would LOVE to know who worked on that plane at AA.
@@MayaPosch all man exactly what ya said. in the old USAF we called it pencil whipping...
That is why the airline workers call them seven dirty sevens.
OMG 😱 no bolts!!!!!!
IF ITS A BOEING, I AINT GOING
Lose bolts, really? What will be next?, nose wheels fall off, smoke in the cockpit? This is a real bonus for Airbus, haha.....
It's like that Top Gear show where they're building a Caterham and Clarkson says "I'm saving time by not putting washers and bolts in"
I was travel in this plane suddenly i also listen boom sound all passengers are praying and after emergency landing we all thanks God we are safe and survive.
Analyse your components
This is gross 🤢
Show the plug not people talking
Nobody advertises for Airbus better than Boeing.
What was cabin pressure at blow out and what would it be at 35000 ?
Boeing needs to stop tinkering with this 56yr old airframe design, retire it and design a new single jet
The question now seems, is or what did Boeing tell individual Airlines, or what Boeing did not tell Airlines which buy Boeing aircraft, over how everything on a Boeing aircraft operates and function etc?
Or what legally Boeing is required to tell Airlines who buy Boeing aircraft, over how everything on a Boeing aircraft operates and functions etc, is a matter for the FAA and NTSB to investigate now?
However, is Boeing responsible as a company, to inform all Airlines Pilots and Cabin Crews, how everything on a Boeing Aircraft operates or functions,?
Or is the Airline responsible, for training of their own pilots and Cabin Crew?
When Boeing provide an operations manual for operators of their Aircraft and all onboard systems too, whether this is to the Airlines own Management, for use by either Maintenance and Servicing Staff, or for pilots and/or Cabin Crew too.
Also which the FAA and NSTB surely should be required to sign off on these Aircraft Operations Manuals, at some stage?
Or maybe now the FAA and NSTB, need to review and inspect all passenger aircraft and freight Aircraft Operations Manuals?
That is from all aircraft manufactures not just Boeings too?
As other aircraft manufacturers may not be informing Airlines or their Pilots and Cabin Crew, or Maintenance and Serving Staff or Ground Support Crews, or Airlines Management too?
Everything they need to know on how individual aircraft or its systems, how they operate and function, in any or all given types of situations or in any emergencies too?
Already the news media coverage of this Alaska Airlines Boeing 737 Max 9 Aircraft Accident Incident, has helped to whip 9 percent of Boeing Share Value.
That is over 13 Billion US Dollars lost to Boeing, that no joke to Boeing or its employee’s, or to Boeing Sub-Contracts and Suppliers around the World.
Including Rolls Royce Aero Engines in Derby included, or to Customers of Boeing either.
Maybe the news media need to think carefully how they are reporting here it could result in lost aviation industry jobs too!
The question not being asked, has there been any issues founded with Boeing 737 Max aircraft, where there is an actually emergency exit doorway opening hatch installed in this same rear fuselage position, Yes or No?
That is compared to the Boeing 737 Max aircraft, which have instead only one of these emergency exit doorway non-opening Plug Sections installed in this rear fuselage position.
If the issue is these emergency exit doorway non-opening Plug Sections and maybe with their four locking bolts and nuts too.
Is this then either a Boeing assembly issues, or an Airlines maintenance and serving issue?
Or is it a manufacturing issue, caused by whoever builds and supplies Boeing these emergency exit doorway non-opening Plug Sections?
Or is it a manufacturing issue, caused by whoever builds and supplies Boeing these four locking bolts and nuts, to secure and hold in place these emergency exit doorway non-opening Plug Sections?
If the issue is these emergency exit doorway non-opening Plug Sections, or their locking bolts and nuts, then the simple answer could be just install real emergency exit doorway opening hatches, problem solved?
Taking MAX now like playing Russian roulette.
Shutter the 737, end of.
Lets just hope the 777x isint as problamatic..i will give that jet about ten years too prove itself before i fly on one
Hey Bob
Make another hole to let the wind out 💡
Ban this low class company now dot
No Highway In The Sky.
Horrible design. This is not a plug door, it’s a panel.
A Boing Boing Bang Ouch 737!.
I think US companies I don’t wanna feel stupid or anti-American. They should focus to buy the Airbus models the a 220s the ea320 Neil and A321, LR or A321, XLR even they should focus get a350-900/1000 or a300-900
Theyre mega safe no major problems only in a350 colour getting bad but 0 problem with doors and engines
Look boeing 787 problems with engines
Nice, how many more loose bolts are there then ? no joke, people should check if their next flight is on a Boeing, and cancel if so, and find an Airbus plane..
yeh right. why should everyone cancel a boeing flight for an airbus one
Sabatagr for sure, disgruntled employees
i wouldn't get on a Boeing aircraft
😮
USA quality.
Ladas of the sky.
If it ain’t #Boeing, I ain’t going! 🛸
Boeing cuts every corner possible. Human life is not even considered in the equation.
PROFIT first and foremost over all else.
Airbus, or I don't fly.
Sounds like a maintenance issue .. Alaskan has a horrible track record
Yup, I think Alaskan airlines is still flying the Max 9 while other airlines have grounded them.
If the door plug was covered up by paneling and the loose bolts were behind it, it's not a regular maintenance issue. Maybe heavy maintenance, but that's after 6 to 10 years of service. The aircraft in question was only a few months only.
😂 lose bolts
Crazy that theese kind of checks arnt done on a more regular basis. Classic example of capatilism at its finest, Profits over anything eles.
If they found one more, Usain would set a new world record.
Lame excuses 🤭🫣🤔🤫
There have been no such incidents with Chinese-made planes, only US-built planes like Boeing. Moral of the story: fly Chinese 🇨🇳 planes exclusively to ensure your safety!
Okay, okay, settle down.
I don’t even cook in Chinese pot and pen🤣
Same with European Airbus
no thanks ill take an airbus.
All manufacturers have issues. China has issues as well but their government controls what information is actually put out.
Airbus 320s right now are being inspected by airlines for having counterfeit parts.
