A New York-bound Virgin Atlantic flight was canceled just moments before takeoff last week when an alarmed passenger said he spotted several screws missing from the plane’s wing.

    While its likely true that the wing panel was both non-critical and secure, I’d be much more worried that if they missed something like that, that they could have missed any number of other things as well. Isn’t there supposed to be some sort of check-list run?

      Pilots perform an inspection of the aircraft before every flight. Missing fasteners on the top of the wing would not be visible during a walkaround from the ground.

      Planes are allowed to fly with many parts missing. A few missing fasteners on a non structural part is fine, but missing fasteners that the pilots are unaware of is a big issue.

    We’re going to have to start walking around the plane with the pilot before takeoff like a rental car dent check.

    Given how completely the airline industry disregards customer service and treats its customers like cattle, I don’t know why anyone would expect them to do a proper job of maintaining equipment. Furthermore, given how eager we are to gut regulation and dismantle the administrative state, all of this is going to just keep getting worse and worse.

    British traveler Phil Hardy, 41, was onboard Flight VS127 at Manchester Airport in the UK on Jan. 15 when he noticed the four missing fasteners during a safety briefing for passengers and decided to alert the cabin crew.

    “I thought it was best to mention it to a flight attendant to be on the safe side.”

    Neil Firth, the Airbus local chief wing engineer for A330, added that the affected panel was a secondary structure used to improve the aerodynamics of the plane.

    Hardy said airline staff repeatedly reassured him there was no safety issue with the wing, but his fear was heightened given the recent ordeal in which an Alaska Airlines plane lost its door plug and a chunk of its fuselage flew off mid-flight.

    “Each of these panels has 119 fasteners, so there was no impact to the structural integrity or load capability of the wing, and the aircraft was safe to operate,” he said.

    “As a precautionary measure, the aircraft underwent an additional maintenance check, and the fasteners were replaced.”


    Noteable comments:

    The fasteners were not “replaced”…they were now properly included, as per the design. The public is not reassured if you cannot use precise or non-ambiguous language. It’s better to state that it was an oversight or be specific: i.e. the design calls for a maximum of 119 fasteners, but allows for a minimum number (x), and thus it was allowed to fly. - tyrionsBeard

    Great! So not only do you have to pay extra for a seat, checked bags but you have to check the wings before take off. That man should be credited for their flaw. - Mabel

    The pilot should’ve walked out onto the wing, slapped a couple lengths of duct tape on that section, then carefully and loudly exclaimed; “ YUP! That baby ain’t goin’ anywhere.” while patting the area firmly.

    I imagine a lot of the passengers were pissed off when the flight was cancelled because one of their fellow passengers reported some non-critical bolts were missing.

      I’d have been grateful.

      I think it’s entirely reasonable to see something obviously missing on the wing of a plane, even something small, and wonder what else isn’t properly secured. I’m sure a plane with four missing allen head screws on that panel is fine. I wouldn’t fly on it without an assurance that it wasn’t a sign of other poor practices.

        First think I look for when I get a system in from a fabricator. Are all the screws on the outside tight and orientationed the same way? If so I am probably going to have a good day. Anybody who takes the effort on something so tiny often is taking the effort in things that do matter.

      It’s not like the passenger knew they were non-critical. I certainly wouldn’t have wanted him to stay silent only for it to turn out they were critical. They also wouldn’t unboard and inspect a plane just on the insistence of one passenger, they’d deplane that one passenger if anything. The fact that they did do an additional inspection implies that safe or not, those missing bolts were not noticed in the initial inspection, which leads one to wondering if they missed anything else.

      I would have been fine with not dying in the event it ended up being a real problem. An inconvenience is better to deal with than a plane crash.

      Planes have so much redundency that theres a lot that’s uncritical, until suddenly it is critical.

      Ideas for a better world #233

      Rename your phone hotspot to “I saw a loose bolt on the outside of the plane” and turn it on in the gate waiting area bar.

          Is there any advantage to those over square (Robertson)? I still see 4 contact points when applying torque. So about on par with square and inferior to 6-lobed torx.

            Well… It comes down to what material is used, as well as requirements and geometry for the screw.

            I love Robertson, but with enough over-torque, you shear the head off the threads or worse, round the hole if there isn’t enough rigid material around the square hole.

            Failure modes are: stretching the material outwards until the bit slips. For the torq-set, you would need to shear the screw head material in front of each of the driver’s tips off and out, much less likely than shearing the head off the threads, or shearing the bit itself.

            Both have the great feature that screws placed on the head stay in place, making installation much easier.

            Aerodynamically, the torq-set has a much smaller ‘opening’ than does Robertson or torx.

            Engineering is all about solving a problem in a quality way now, and ideally, considering issues for the future. A downside could be ice/grit getting stuck inside the smaller opening, as an example.

    At some point, that part was taken off the plane and it was replaced, or maintenance was done on it, or maintenance was done on something underneath it. It was then replaced. There is a documentation trail that says all of this was fully completed. The documentation was signed off on by someone who was qualified in this task, and/ or by a supervisor who checked it off.

    If there is no documentation, or if the documentation indicates something was done that was in fact not done, the CAA/ FAA is going to have a big problem with this. They are sort of interested in how maintenance is done and documented. If they didn’t do this right, what else are they/ have they been “pencil whipping?”

    I can see a pretty thorough inspection of their maintenance practices and documentation in the near future. If they find a pattern of this, the maintenance gets decertified and the airline can’t fly until they are cleared.

      There’s a massive failure in maintenance and Operations’ culture here. This isn’t the exact sort of situation where you’d use LOTO, but you need something similar. Lock the engine in the off position until the removed part is properly reinstalled.

      I want to call maintenance errors like this rookie… But they really aren’t. There’s plenty of plant incidents where people either don’t have a proper procedure or don’t follow it, and a welder tries to work on a live gas line. Or someone opens a valve without realizing it needs to be closed.

      I still say we fine the companies and hold the CEOs personally responsible, because the buck stops there, and these mistakes are more likely to happen in an organization that doesn’t have a robust safety culture.

      Regular Inspections fix small issues before greater problems arise from them –> some economist with no technical knowledge or common sense goes: hurp de durp our inspections never fix any relevant defects. Better cut back on them to be more economic. –> surprisedPikachu.jpeg

        Regular inspections are already mandate by the FAA, no economist, accountant or MBA has any say on it.
