The hotel keycard was used to check seals of doors, the dishsoap was used to lubricate the door seals to make them fit better.
The documentation about the steps were vauge and badly documented, neither of which I want in the documentation for building aircraft.
But tell me if the CEO and shareholders are still getting their bonuses and stock buy backs?!
Well obviously!
Thank God, for a second there I thought the top 1% were going to be held accountable for their actions.
No, no, no, no, no, no - the Law is still only for the little people not for important people.
Worry not, everything is still as it's meant to be.
Tbh, I don't see a problem with using Dawn dish soap and hotel key cards.
When another company has already made a product that perfectly suits your needs it's absolutely reasonable to utilize that product.
The issue is that if they are doing this, it means that the workers doesn't have the proper tools for the job.
The keycard should be replaces with a go/nogo custom card, and the soap should either be specified by brand in the manual or swapped to a certified lubecricant, that has been tested to work fully with the gasket and not cause deteriation or on any way affect the quallity of the seal.
I can't know for certain what is specifically going on there but I do work in contract manufacturing for high end scientific equipment and critical medical electronics so I do know a fair bit about the processes used. For me the dishsoap and keycards on their own don't raise any alarms. It sounds like the main issue is poorly written incomplete manufacturing instructions, which is a big enough issue on it's own and is an absolute monster to try and fix once your production workers have gotten used to working like that.
the soap should either be specified by brand in the manual or swapped to a certified lubecricant, that has been tested to work fully with the gasket and not cause deteriation or on any way affect the quallity of the seal.
The seals used are most likely silicone (it's what we use on environmental chamber doors). If so there are very few chemicals that will harm them let alone dishsoap. We actually use 409 (a bathroom cleaner) spray to lubricate our seals where I work.
The dishsoap is almost certainly something they order and stock with their own internal shop supply number. The instructions most likely reference that number but that number would be meaningless to anyone else so the news article just said dawn dishsoap. It's not going to be any random dishsoap because that's not how industrial supply works. It would be more expensive for them to go pick up random dishsoap than to just keep ordering the same part number (that specific dawn dishsoap) in bulk from their industrial supplier.
The keycard should be replaces with a go/nogo custom card
Why in the world would you make custom tooling when there is a readily available off the shelf solution? You can just buy packs of keycards for dirt cheap and they are going to be a known thickness because they need to be to keep working in the same keycard slots. That thickness should be documented somewhere but it isn't going to be in the manufacturing instructions because the production people don't need it; they just need to know that the go/nogo gauge (the keycard) should fit. The more extraneous information you include on manufacturing instructions the greater the chance you have of someone missing or misreading something. If someone needs that extraneous info or something on the production floor isn't right that's when you bring in the engineer or process support staff who will have access to that info and the authority to make decisions based on it. If your production staff are making critical decisions on their own then something is very wrong with your manufacturing instructions (which sounds like the real problem here).
Submariner here. After several incidents in which submarines imploded, burned, or otherwise caused death and/or endangered thermonuclear weapons systems, our current procedures specify every single item used down to specific serial numbers, with specific authorized substitutes. If the authorized substitute cannot be found, the procedure is simply not done, and if necessary for ensuring the actual safety and conduct of the submarine's primary mission, the entire multi-million-dollar mission is cut short and the ship surfaces to either receive the requisite supplies or goes back to port. Specific serial numbers for lubricants, specific stress-tested seawater-proof pressure-resistant alloys for bolts, specific serial numbers and part numbers for fuses, specific torque wrenches, even specific serial numbers for indicator lights. Every single maintenance step of certain procedures are read out loud at least three times and re-confirmed and acknowledged by both the worker and supervisor before being conducted, including the opening and closing of maintenance panel doors.
Sounds tedious and like it costs too much, fuck it let's not do that - some asshat at Boeing
If the dishsoap is standardized in the documentation I don't see any issue with it.
The hotel keycard, less so, since it is used to meassure how tight a fit is it will inevitably get worn, so the card needs to be durable with a predictable wear pattern, I have had hotel keycards made put of all kinds of plastic, paper even wood, they all have drasticly different thickness, wear patterns and durability.
If the documentation is too generic it looses it's meaning.
All of the big hotel chains use the same plastic key cards that are credit card sized, they are durable and can be reused many times but also cheap enough to not fret over them if a customer forgets to return it before leaving. As a former aircraft maintainer myself, I don’t personally think it would be an issue if Boeing or its contractor ordered a bunch of standard hotel card blanks for seal testing, but if they were meant to use that as their test device it should be documented , there should be a part number for that card and authorized suppliers, and there should be a specific procedure to follow when using them. The article mentions the lack of documentation, so this was probably an unauthorized improvisation on the fly. I doubt these were being used to measure a specific tolerance, this case was probably something stupid like “the cabin pressurization check failed after we replaced the door, let’s poke a card along the seal to find where the gap is and squeeze extra sealant in that spot.” My specialty was avionics though, so I will admit I don’t really know much about the pressurization checks and seals, I was always at the plane for some other work whenever I encountered them.
I fully agree with you, the keycard itself isn't the main issue, the lack of documentation and standardization is.
I read the article as if it said that the workers at the floor had a bunch of random keycards they used for fit testing.
If it was standardized on specific keycard blanks I would have zero issued with it.
That's a big conclusion you're jumping to.
At my old job we used PAM cooking spray and credit cards. It was written into the documentation, btw.
(This was a global company, btw, not a ma and pa shop).
If it was written into the documentation, then I'd expect it to be fine as the company would be liable.
57% is owned by institutional investors who ruined the company.
Scumbag investors have intentionally ruined one of the best companies in America.
JSYK.
Hey, but imagine how much their dicks get sucked with all that money?
It's really not the Investors. Boeing had Investors before and it all went fine. It's the McDonnel Douglas leadership that took over that ruined it.
Don't forget, they're also killing whistleblowers! Real rough time for Boeing. Boo hoo
How does this part (which is what the headline refers to and presumably the most outrageous inspection finding)
At one point during the examination, the air-safety agency observed mechanics at Spirit using a hotel key card to check a door seal [...]. In another instance, the F.A.A. saw Spirit mechanics apply liquid Dawn soap to a door seal “as lubricant in the fit-up process,” according to the document. The door seal was then cleaned with a wet cheesecloth
have anything to do with the opening of the article
Just last week, a wheel came loose and smashed through a car, and earlier this year the door from a 737 Max aircraft broke off mid-flight
???
The article misses the whole point, which is that the audit did not uncover the sources of these incidents.
The audit was not about finding the exact cause of the previous incidents:
The audit, which is kind of like a quality control inspection for large companies, analyzed 89 aspects of Boeing’s 737 Max production
The audit looks at current production to assess wether or not everything is being done to prevent further hazards (they failed over a third of the inspections). Determining what caused the past incidents would be assigned to the equivalent of crime scene investigators (FAA detectives?).
Determining production line compliance and investigating the cause of a major malfunction are two entirely different beasts.
To expand on "FAA detectives", a specific incident would be investigated by the NTSB (National Transportation Safety Board).
Neat fact to know. I always love learning new things.
The issue with those items is that they are not in the list of approved materials for Boeing's manuals. It might be normal to see these sort of practices in a line maintenance environment where it's hard to get the proper tooling; but the manufacturer should be abiding by it's own regulated publications. It's just more symptoms of their cost cutting and schedule rushing measures that are leading to their quality issues.
My company has been spending a lot of time and money doing warranty repairs on brand new airplanes that we received from Boeing over the past couple of years. It's very concerning when a customer has to fix things that should have never left the factory floor.
The part about the crappy QA process explains why the delivered planes keep having problems.
Not to me. Absence of QA allows faulty parts to make it into a plane, it does not explain why there are faults in the first place. For doors and wheels popping off there have to be either lethal part design mistakes, parts made from play doh instead of aluminium/steel, or the people on the assembly line throwing fasteners in the bin instead of putting them on. It's not like a door pops of because its seal touched soap once and somebody poked an unverified piece of plastic at it. Especially in aviation, where you need to have redundancies.
I think it's an issue of tolerance. They should be using gauges to test the fit, because hotel keycards can vary in thickness. Gauges are stupid cheap compared to the cost of the plane. It's evidence of cost-cutting bullshit.
Same with using dish soap as a lubricant. It's the wrong material for the job. Soap leaves a residue, and dissolves other lubricants. If there's supposed to be lubricant in the door, the soap is a bad choice. If there isn't supposed to be a lubricant in the door, then soap is a bad choice. It's like Schrodinger's lubricant. You won't know if it's a problem until it's a problem.
No manufacturing process or material design is perfect. You get as close as possible, and then QA catches the mistakes.
For Boeing, it sounds like they didn't try very hard to perfect their processes, and then didn't bother with QA.
In addition to what the others said, I think the wheel thing was probably not boeing's fault. That plane was delivered to United 22 years ago. It could have been a manufacturing error, but it was probably a maintenance error.
They should have used Palmolive.
Plane crash into the ocean? You're soaking in it.
I don’t know why, but that commercial literally popped into my head yesterday when I went somehow found myself in a mental tangent thinking about the product name wondering if they used palm and olive oil. Then of course synthetic palm oil and how would they test that since I haven’t heard about dishpan hands since the 70s.
They're experimenting with how to build planes as cheaply as possible, and anyone who dies is just collateral damage.
So long as they save more on the planes than they spend on the lawsuits it's a win according to investors.
Exactly.
Corporations have a legal requirement to provide value to the shareholders. That's it.
I can already hear the Behind The Bastards episode about Boeing.
