There is a famous story about how an F16 got grounded because an half inch metal pin was missing from the cockpit canopy. Nobody knew what the pin did or if it was even necessary but you can't fly a plan that 'missing a part'. After several days of being grounded they finally reached out to a guy who had retired 20 years ago who told them the pin was a part of a analogue sensor that had been replaced nearly 30 years ago. Only the pin remained as a vestigial organ since it was part of the airframe design.
It doesn't matter how well you document things there will always be tribal / personal knowledge.
Even if stuff is written down you have to know where to look.
- gwbas1c 1mo ago> Even if stuff is written down you have to know where to look. That's one of the things I love about AI: It's excellent at figuring out where to look, because it can digest so many documents so much faster than a person.
- SteveNuts 1mo agoYeah it’s great to point an AI at a very detailed and specific engineering manual and have it distilled down into bullet points. There’s certainly no room for information loss in that plan! /s
- compiler-guy 1mo agoPlus everything important is always written down. It’s more true in aviation than anywhere else (except maybe space flight), but still.
- kjs3 1mo agoAnd if it's written down, it's accurate. 100. Percent. Accurate. /s
- pineaux 1mo agoAnd because it's accurate the AI will know how to weigh that accurate information against other accurate information in such a way that it will give you a great answer without any help. In other words: any amateur will be able to do aircraft maintenance! What can go wrong? /s
- lazyasciiart 1mo agoYou know, if I had to make that bet, I would choose airline maintenance manuals as the test case.
- kjs3 1mo agoHave you seen the maintenance manuals on an aircraft production line? They're in 3-ring binders, so you can take out and replace pages. They are constantly being corrected and updated. The industry recognizes they're never at 100% (and to their credit mitigation is part of the process).
- IAmBroom 1mo agoI hate AI as much as anybody, but claiming that it's not useful for "distilling volumes of data into a short list of places to look first" is silly.
- SteveNuts 1mo agoIt’s very good at that, but aeronautical engineering and maintenance is the last place you’d want that.
- msl 1mo agoGP did not suggest anything of the kind, though. They talked about "figuring out where to look" which very different. In that kind of use, it doesn't really matter that the model might hallucinate or draw faulty conclusions, as you're not using it figure out what to do, how or why. The only thing it is telling you is where some information is located, after which you go check it out from the actual source of truth. If the reference turns out to be wrong, you'll notice immediately.

- speed_spread 1mo agoChesterton's fence is strong with this one
- tomxor 1mo agoExactly. Framing completely changes this from an absurd story causing pointless grounding due to loss of institutional knowledge, to an example of good judgement (or protocol) in the absence of knowledge and acknowledgement of the risk of unknown consequences. What's being ignored is the 1/100 of these stories where this judgement pays off, saves aircraft and lives that make the other 99 worth while.
- bonesss 1mo agoI babysat for a military fighter jet mechanic when I was young, he said when they dismantled and rebuilt planes there was a drawer for all the spare parts that were left over.
- sokoloff 1mo ago> but you can't fly a plan that 'missing a part' It’s a great story, but I assure you there is a pretty high percentage of airplanes flying with missing parts and systems placarded as INOP in both military and civilian aviation.
- m463 1mo agoI remember touring the assembly line for military jets. There were posters everywhere about "extra parts" they called FOD.
- dghlsakjg 1mo agoFOD applies more broadly than that, as well. Candy wrappers on the runway is also FOD. It stands for foreign object debris, and means any physical thing out of place where it may cause damage or injury. Because of the nature of jet engines, basically anything can be FOD depending on where you put it.
- RobRivera 1mo agoThe 'forest for the tree' here is that when it comes to general operations, a crew chief doesnt generally have the authority to signoff a bird as flight-ready for an unaccounted component. That is the authority of a PMO or a Risk Officer or someone else in flightoos, not a frontline maintenance call. Maybe someone in a maintainence squadron?
- buildsjets 1mo agoBefore you can placard something as INOP, you must determine whether the manufacturer and certifying authority have included that part in the Minimum Equipment List or Dispatch Deviation List. Mechanics do both get to determine this at their own discretion. Hence the call to the manufacturer for clarification on the necessity of said pin. To reiterate, you CANNOT fly an airplane with an undocumented missing part. If the part is documented in the logbook as removed, and it is acceptable to fly that way, then it is not missing. I have been building and maintaining commercial aircraft for a living for 30 years. What is your experience?
