Boeing Says Some 737 Max Planes Might Have Defective Parts (cnn.com) 128

"Boeing on Sunday said some of its 737 planes, including many 737 Max aircraft, may have faulty parts on their wings," reports CNN. Working with the Federal Aviation Administration, Boeing said it has reached out to airlines that fly 737 planes, advising them to inspect their slat track assemblies on Max and NG aircraft. The 737 NG series includes the 737-600, -700, -800 and -900 planes. Leading edge slats are an aerodynamic control surface that extend from the front of the wing. Some the tracks may not meet manufacturing standards and may need to be replaced, Boeing and the FAA said. They said if the parts are found to be defective, airlines should replace them before returning the planes to service.

The faulty parts could fail prematurely or crack. The FAA said a part failure would not bring down a plane, it could damage an aircraft while in flight. Boeing has sent out a service bulletin and the FAA will issue an airworthiness directive requiring airlines to inspect and repair its slat track assemblies within 10 days.

The company discovered the problem Friday, when Boeing was meeting with the parts supplier. Boeing employees noticed some of the parts were not heat treated, which led them to believe there might be a safety issue.

CNBC reminds readers that the Boeing 737 Max have already been grounded worldwide after two fatal crashes, with airlines cancelling thousands of flights through August.

"Boeing's CEO, Dennis Muilenburg, last week said the company had to regain the public's trust...."

      Boeing is currently facing a fleet of aircraft which are grounded, a group of operators who are ticked off because they have paid for aircraft they cannot fly until Boeing finishes re-certifying the whole aircraft from wingtip to wingtip, nose to tail, all due to what amounts to a software and training deficiency they let slip though their certification process.

      You can add external regulation (there already is some). Just don't expect too much from it. Think of the SOX auditors that are very serious about making sure everyone changes their password every three months. It's security theater.

      In the worst case, external auditors will just give Boeing someone to offload the blame to. I don't really have a solution, but there is not likely a magic bullet.

        There is a free market solution here that works 100 percent. If enough people die in plane accidents, other people will stop buying tickets. And neither will the dead ones. The invisible hand of the free market will eventually put that airline out of business.

      I predict that if one looks, one can find major manufacturing failures and probably also design flaws in everything Boeing has done for a decade or more.

      You can blame FAA for this, but not in the way you think. FAA has been allowing Boeing to self-certify their planes for a while. It's sheer stupidity. What's the point of the FAA even existing now?

      FAA: All good?

      Boeing engineer: Yep.

      FAA: Kick the tyres, light the fires!

      • Out of interest, what exactly do you think the EASA does with Airbus? Yup, self certify to the same degree - the EASA simply takes the results of the Airbus certification program and checks it over for obvious issues.

        If Airbus finds obvious failures itself, it discusses the matter with the EASA and they come to a mutually agreed conclusion - for example, the A380s wing failed its ultimate load test, and was eventually passed by statistical analysis of the fix.

        The FAA then accept the EASA certification, as

        • Most of the wings for modern airplanes fail the first test because of the imperative to build light. Then they are usually strengthened and retested, and exactly that happened to the A380 wing. I remember the video of the passed second test.

          • Really? The A320, A330, A340, A350, 737, 747, 757, 767, 767 and 777 all passed first time...

            Breaking during the test is very very much an outlier, not the norm.

            And its interesting that you say you saw the video of the second test, because there was no second test - they determined what structural changes were needed and then certified the wing by statistical analysis, they didn't do a second ultimate load test.

      It WILL bring down the plane when your're on low approach and your slats get jammed up before full extension, and the rest of the system thinks they are, and your throttles cut airspeed, and you drop from the sky onto the ground in an unexpected stall you have no time to recover from.

    "The FAA said a part failure would not bring down a plane, it could damage an aircraft while in flight."

    Wrong. This kind of failure could bring down a plane. To say it couldn't is foolish at best and criminally misleading at worst.

    You'd be surprised what could bring down a plane, sometimes it's the littlest thing.

    For example, check out China Airlines Flight 120: https://en.wikipedia.org/wiki/... [wikipedia.org]

    "When the aircraft retracted the slats after landing at Naha Airport, the track can that housed the inboard main track of the No. 5 slat on the right wing was punctured, creating a hole. Fuel leaked out through the hole, reaching the outside of the wing. A fire started when the leaked fuel came into contact with high-temperature areas on the right engine after the aircraft stopped in its assigned spot, and the aircraft burned out after several explosions."

    It was just luck that this didn't happen earlier, possibly in flight. If they'd had to wait to taxi to the terminal (for departing aircraft runway clearance, for example) this might have happened before they got to the terminal. It could very well have happened in flight.

    "... the washer on the nut side of the assembly was omitted, following which the downstop on the nut side of the assembly fell off and then the downstop assembly eventually fell off the track."

    That's right- one missing washer caused this near disaster.

    So please, don't tell me that problems with the leading edge slats (!!) couldn't cause a fatal accident.

      One year before the suddenly announced merger (there was no plan for merger at all) MD was in the process to join venture with China to develop a commercial passenger plane.

      US government stepped in to stop the JV with China, but it was too late. To kill that JV the US government forced Boeing into acquiring MD (as I said before, there was absolutely no plan for the MD/ Boeing merger at all before the US government stepped in).

    Many people have suggested that the corporate culture shift at Boeing after the McDonnell-Douglas merger led directly to all of these problems in recent airplanes. But even if they're wrong, the risk inherent in having only two full-size jet aircraft manufacturers (Airbus and Boeing) was brought into stark relief by the 737 MAX problems.

    Consequently, IMO, the best thing that could happen to the industry would be for the government to break up Boeing. I know more than two decades have passed since then, but better late than never.

    • That won't happen. With Trump you're going to get less regulation of the businesses so more things like this are going to happen. Everything is being set up for another GFC as even the small protections that were put into place after 2007/8 start getting rolled back and the financial companies get ever more creative.

      Into what though?

      I'm not anti-regulation, but for any kind of regulation to be effective, it needs to be designed well which means we need to know what the end result we want is. So if Boeing is to be broken up, what should it be broken up into?

        Also consider that smaller aircraft manufacturers have just been snapped up, with Airbus taking a sizeable stake in Bombardier (the C-Series is now the A220) and Boeing buying into Brazil's Embraer (the E-jet series hasn't been renamed...yet). These acquisitions are happening for a reason (greater access to R&D, distributed manufacturing, et al) so breaking up manufacturers may not be such a good idea.

        To be clear, I'm not talking about a complete breakup. I think Boeing should keep the Embraer corporat

  • That's worse than just having defective parts.
  • > The FAA said a part failure would not bring down a plane, it could damage an aircraft while in flight.
    Agreed. A slat failure usually does not bring down a plane. You end up with a "higher than normal" landing speed and that often ends well. It doesn't happen often, but it does occasionally happen.

    However sometimes it does go wrong. See Moskow, a couple of weeks back. That was a "nothing special, just a bit high landing speed" landing. It did NOT end well.

    • That was not a high landing speed, that was a hard nose down resulting in a bounce.
      As long as the landing speed is below the tyre maximum speed and the flaps extension speed and as long as there is enough runway to brake, a higher than usual landing speed is really nothing special, but it will result in more brake and tyre wear.

    If you look at the discussion about corporate culture at Boeing, at the relentless cost cutting efforts, and all these things which led to two awful disasters, then you wonder whether Boeing's recent stock price crash will teach a lesson to share holders. It looks like it won't. A quick look at Boeing's stock price over the last five years confirms, that it is still way up. [nasdaq.com]

    In other words: it pays off to sacrifice flight safety for the mighty US$, everyone who invested into this for more than a year made a hefty profit and will ask for more of the same.
