Boeing Whistleblower Raises Doubts Over 787 Oxygen System (bbc.com) 138

A Boeing whistleblower has claimed that passengers on its 787 Dreamliner could be left without oxygen if the cabin were to suffer a sudden decompression. The BBC reports: John Barnett says tests suggest up to a quarter of the oxygen systems could be faulty and might not work when needed. He also claimed faulty parts were deliberately fitted to planes on the production line at one Boeing factory. Boeing denies his accusations and says all its aircraft are built to the highest levels of safety and quality. Mr Barnett, a former quality control engineer, worked for Boeing for 32 years, until his retirement on health grounds in March 2017. From 2010 he was employed as a quality manager at Boeing's factory in North Charleston, South Carolina.

In 2016, he tells the BBC, he uncovered problems with emergency oxygen systems. These are supposed to keep passengers and crew alive if the cabin pressurization fails for any reason at altitude. Breathing masks are meant to drop down from the ceiling, which then supply oxygen from a gas cylinder. Mr Barnett says that when he was decommissioning systems which had suffered minor cosmetic damage, he found that some of the oxygen bottles were not discharging when they were meant to. He subsequently arranged for a controlled test to be carried out by Boeing's own research and development unit. This test, which used oxygen systems that were "straight out of stock" and undamaged, was designed to mimic the way in which they would be deployed aboard an aircraft, using exactly the same electric current as a trigger. He says 300 systems were tested -- and 75 of them did not deploy properly, a failure rate of 25%.
Mr Barnett also says that Boeing failed to follow its own procedures, intended to track parts through the assembly process, allowing a number of defective items to be "lost."

"He claims that under-pressure workers even fitted sub-standard parts from scrap bins to aircraft on the production line, in at least one case with the knowledge of a senior manager," reports the BBC. "He says this was done to save time, because 'Boeing South Carolina is strictly driven by schedule and cost.'"

        who merged McDonnell-Douglas. The 787 was launched under his tenure, after Boeing was in the gutter, having had huge US Government procurement blacklisting problems.

          It's a textbook example of short term greed capitalism. Weirdly, the history of the company is like a textbook example of capitalism's paradoxes -- the ability to produce a company that did some amazing things, yet is now self-immolating because greed and ego took over.

        This is what happens when corporations can buy laws. They inevitably buy laws which stifle competition, and one of the easiest ways to do that is to make it cheaper not to do a new design. Compare the laws for getting a drug approved in the USA. A new form of an already approved medication only needs to be shown to not kill statistically significantly more people than the old one, you don't have to prove that it's even as efficacious as the old one — let alone moreso.

          You can remove all regulations from the aircraft manufacturing process and it will still not be cheaper to do a new design than to tweak an old one. In addition, a truly new design risks huge failures.

        It will always be much easier and cheaper to tweak an existing aircraft design than to do a clean sheet design of a new aircraft, regardless of regulations, especially if economic risks are taken into account.

    Weird.

    Most passenger aircraft only use oxygen cylinders for the crew. To save the weight of tanks to hold enough oxygen for a few hundred passengers, the pax generally have to make due breathing from oxygen generators, not cylinders. I wonder why Boeing switched for the 787. Maybe this is a case of some new technology... a rebreathing or CO2 scrubbing system... being shipped while it's still half-baked? I wish the article supplied actual technical details.

    • by sjames ( 1099 )

      I wouldn't read too much in to a reporter's understanding of the tech. My guess is that since it's roughly cylindrical and provides oxygen, so he called it an oxygen cylinder when it's actually a generator.

        I googled around and found a parts list [beaerospace.com] which suggests that it's simply a higher-pressure oxygen cylinder. (Search for "pulse")

        Then I used their site search and found the pulseox product [rockwellcollins.com] which apparently uses electronic control to deliver oxygen based on breathing patterns.

        So no, it's not a generator. It uses tiny, high-pressure tanks, and a circuit board with sensors on it. And in classic Boeing style, it appears (from the logic board photo) to only have one sensor per passenger. And this was pretty easy to find by just looking.

        • by sjames ( 1099 )

          They also list an oxygen generator on that page, so it's unclear which is used where, though there are clearly some systems using pressurized tanks for passenger emergency oxygen.

          • They also list an oxygen generator on that page, so it's unclear which is used where

            It's conceivable that they support using a generator with the pulse system, but I looked for parts which said "(Pulse System)" next to them... which the generator does not. If you want the final word, though, you'll probably have to contact BE Aerospace.

      Apparently it's not standard oxygen cylinders - it's "advanced technology" aka "cheaper":

      The Boeing 787 will be the first aircraft equipped with a passenger oxygen system using B/E's advanced "Pulse Oxygen" technology. The Pulse Oxygen system delivers oxygen more efficiently than traditional passenger systems, and reduces overall system weight and fuel burn. The Pulse Oxygen system also facilitates lower maintenance and cabin reconfiguration costs, when compared to traditional oxygen systems.

        We glider pilots use pulse O2 systems most of the time these days, they work very well and use much less O2 than the older constant flow system. The pulse Ox controller known as the Mountain High EDS is very popular. It runs for 50 hours + on 2standard AA batteries, and can be set to start at ground level, 5,000ft or 10,000ft automatically.its good to 18,000 with a canula and 25,000 with a mask.

      Weird.

      Most passenger aircraft only use oxygen cylinders for the crew.

      Pretty much... The PAX oxygen system is mostly for show. If an aircraft is at cruise height, there's less than 30 seconds to put on an oxygen mask - and passengers really haven't trained for it...

      If the crew oxy system doesn't work, there's issues... The pax one? Eh - they'll wake up again below about 15,000ft....

      • Less than 30 seconds? A healthy adult should have at least a minute or two. I can hold my breath for 30 seconds without too much trouble and zero risk of passing out. Someone who has trained for it can hold their breath for several minutes. Breathing even 30,000ft air should supply a decent bit more oxygen to the brain than holding one's breath.

        • by Agripa ( 139780 )

          Blood oxygen saturation is non-linear with partial pressure of oxygen so it gets worse more quickly then you might expect. At 25,000 feet you have 3 to 6 minutes before unconsciousness and will die not long after. Before losing consciousness you will be impaired very quickly.

          Holding your breath at at sea level is one thing but completely different with a 10psi difference at 25,000 feet. You might as well try to hold your breath in a vacuum; it is not going to happen.

    I lasted exactly 45 days at GE Aerospace. When I brought up 'bad decisions', one of the other contractors joked that "This isn't even the worst decision [he's] seen". As if that was supposed to make it better. If you don't do the work, they'll find someone else that will.

    Thankfully this won't possibly kill any civilians. And, to quote verbatim the "joke" that was told on my first day, "I guess that's what they signed the waiver for", since it was a military project.

    Modern aircraft not killing more people has to do more with luck and what remains of DO-178B. (Without the self certification and midlevel managers trying to work around it).

    There is a safe, meticulous middleground that is not Coldfire v4e and 286 chips in 2019 or what ever the flavor of the week of JS framework. However it's expensive, requires competent engineers, and an actual a safety culture.

    American Aerospace is terrifying. Even companies that have a culture of safety in their automotive divisions just see $$$ and throw it out the window for their aerospace.

    From a previous post:

    The Downfall of a Great American Airplane Company - An Insider's Perspective [airliners.net]

    During the past several years, Boeing Commercial Airplanes has been offloading its design engineering work to foreign "design centers". American engineers and technical designers are being laid off by the hundreds while Russian engineers are quietly hired at the Boeing Design Center in Moscow. Many of the Russian engineers are not nearly as experienced as the American engineers being laid off. Engineering layoffs have cut so deeply into Boeing's talent pool that knowledge has been irretrievably lost. And the layoffs continue.

    Soon Boeing may reach (if it hasn't already) a "point of no return" where irreversible damage has been done to the company's ability to design and build safe airplanes, even with its so-called "risk-sharing partners".

      My opinion of the functional safety (don't kill people) industry with my ear to the ground working and interviewing in multiple industries.

      For who you should trust not to kill you, in this order:

      1. German/Japanese Automotive
      2. Heavy Equipment/Industrial
      3. 'Old' American Automotive
      4. [Large gap]
      5. 'New' American Automotive
      6. American Aerospace
      • Germans and Japanese have been steadily marching towards ADAS5 [techrepublic.com] for a long time. They're just doing it piece meal and methodically. [I also trust TUV certifications above the FAA at this point.]
      • Industrial/Off Highway is safe because their stuff is expensive, killing people in regulated areas like mines is expensive and most importantly a dead operator/broken machine isn't turning profit. Caterpillar, Deere and CASE are all taking slightly different NIH approaches. But going slowly. Caterpillar mining truck will be a safer bet than an Uber ATG vehicle.
      • Old American automotive is trying, bless their hearts. But you still have stuff like GM.
      • Uber ATG was a whole interview of WTF. Their brilliant strategy for making bank at an IPO was: 1) Hire a bunch of academic geeks and give them unlimited resources (2015) [theverge.com] 2) Hire a bunch of silicon valley dude bros to manage them. (2016) Throw money at it. When that didn't work and someone dies, then go looking at above company alumni for 'functional safety engineers'. (2018)

        Off the top of my head just from the interview (Mid 2018): They weren't doing any HIL testing. [dspace.com] Their 'test plan' was "put an engineer at the wheel to be an engineer and driver." When 2007 diesel emissions work was in full force a semi would have 2-3 engineers *plus* a driver to collect data and tune the emissions equipment. And none of that was even safety related. Trying to make an engineer watch their laptop to 'see' what it sees and see what is being seen ahead *and* controlling the vehicle is stupid and cheap.

        They were in a race to the IPO at which point having actual product didn't mater. But given the news of layoffs [thestreet.com] my guess is they're crashing and burning internally right now.

      • American Aerospace has benefited from no competition and unlimited military budgets. The lack of competition is trickling down to suppliers like UTC and Rockwell Collins. They have no reason to get better. Their customers have no choice and there is a lot of money to be made.

    When Boeing makes a statement like that "all its aircraft are built to the highest levels of safety and quality," I ask myself what does Boeing have to loose if they are wrong? Would the cost to Boeing be so great for allowing the lost of life that the profitability of the company would be at stake? Or can they gamble with known issues resulting in a lost of life while the life of the company largely not be impacted?

    The Boeing 737 MAX 8 victims fund seems to answer this question. Each victim's family is being provided $144,500.

    Now let's put the cost of a life in Boeing terms:

    Boeing CEO Dennis Muilenburg has a salary of $23 million. The value of a life to Boeing is worth less than 0.7% of the Boeing's CEO salary.

    Boeing net income was $10.46 billion. The value of a life to Boeing is worth less than 0.002% of Boeing's net income.

    So, when Boeing says they believe all their aircraft are safe, that gives me about 0.002% to 0.7% increase in confidence from zero they are commitment to addressing every known issue which could compromise my life by using their product.

    But at the end of the day, I reached the conclusion that I value my life more than Boeing does. The degree to which their claims are actually backed by hard numbers regarding value just is not nearly good enough. I don't expect Bernie Madoff to help make me rich and I don't expect Boeing to get me to a destination safely.

    Boeings golden years were up until the 1990s. The 777 was a great plane made in the last years that Boeing had an engineering centric culture based on quality. Muilenberg is not necessarily to blame because he came in at the later stage of the 737 Max program and deserves some credit for being an engineer rather than an MBA type that created this mess. Boeing needs a new board structure with at least 50% engineers out of at least 10 members, or perhaps 35% engineers and 35% plant workers, and get rid of this cost cutting culture and get back to being engineer driven.

    • Mulenberg WAS an Engineer. He was the one involved with the MAX, and put pressure on the company to override the chief engineer who did NOT want the MAX design.

      BUT, I agree with the rest of what you say. Boeing really was a company devoted to Quality. Right now, it leaves a lot to be designed because of the last 4 CEOs that we had.
  • Could be jacking with Boeing too. Anyone know if their contracts are up again?
