Jesus Christ, get it together. https://www.dailymail.co.uk/news/ar...new-planes.html Misdrilled holes on 50 MAXes at Spirit. The good news is that it's a Spirit employee that noticed misdrilled holes and raised a red flag. The bad news is that, you know, it happened after *fifty aircraft* went past without anyone noticing.

is this the second time or are these different mis drilled holes? edit: the latter, apparently. holes in the aft pressure bulkhead were found to be mis-drilled last year. Arson Daily fucked around with this message at 03:42 on Feb 6, 2024 |

The Royal Air Force dispatched two Typhoon Fighter Aircraft to intercept the A320, which entered a hold (one racetrack) near Newcaste upon Tyne,EN (UK) in the meantime. The aircraft subsequently continued the flight to Manchester accompanied by the Typhoons and landed safely on Manchester's runway 23R about 50 minutes after the aircraft entered the hold. I was initially wondering if there was a bird strike that damaged a VHF antenna or something hence being able to communicate with the fighter 1nm away on guard but not anyone on the ground.

Warbird posted:I presume this is SOP with a presumption that it was hijacked or something? From what I pieced together the sequence of events is that the flight didn’t check in with British ATC when initially expected over the North Sea, but then did before approaching the coast. ATC then put into that racetrack pattern you can see most of a loop of over Durham while the flight was intercepted. This is probably why the initial contact from the typhoon is not very aggressive and the flight responds with the exasperated “is that necessary”. That sequence also makes you wonder if there was no equipment failure and someone miskeyed a frequency or was pushing the wrong tx button or some similarly embarrassing reason to have armed “assistance”. From the point of view of British air defense, I assume their thinking is that they have an aircraft that there was no continuity of contact with so they need to confirm its identity (the visual inspection of registration) and then have a way for the plane to safely traverse British airspace in case there’s further communications issues. edit: avherald is saying that all communication was lost including transponder so surely that excludes simpler things like fat fingering a radio or something? The aircraft operated another flight after 2 hours though which indicates they knew what was wrong and fixed it? hobbesmaster fucked around with this message at 16:54 on Feb 6, 2024 |

The NTSB preliminary report on Alaska 1282 is out (although the server is very hard to reach at the moment). As expected they conclude that the retaining bolts were not installed. They have also been digging through manufacturing records and found there's photo evidence of the door plug lacking its retaining bolts: The reason for removing the plug is stated to be damaged rivets, which is consistent with what the whistleblower posted a few weeks ago.

big companies use all kinds of janky enterprise messaging systems for employees to communicate because they have lots of requirements to retain data (which of course on the flip side is license and incentive to shred everything they can as soon as nothing requires them to keep it) i can't load the doc to check but i would expect (hope maybe?? it IS boeing.....) that "text message" means something on Teams or some similar kind of managed system. legal jargon hasn't really caught up with technology so you'll often see "text message" to mean electronic things that aren't emails or letters or w/e still not a very good system for documenting anything but it would be "official" e: vvvv yeah stuff like that too! the milk machine fucked around with this message at 00:26 on Feb 7, 2024 |

It could also refer to the non-recordkeeping system used for "management communications" described by that whistleblower in the news site comments the other day. Which, interestingly, this report matches up bang on with. random internet commenter posted:A brief aside to explain two of the record systems Boeing uses in production. The first is a program called CMES which stands for something boring and unimportant but what is important is that CMES is the sole authoritative repository for airplane build records (except on 787 which uses a different program). If a build record in CMES says something was built, inspected, and stamped in accordance with the drawing, then the airplane drat well better be per drawing. https://leehamnews.com/2024/01/15/unplanned-removal-installation-inspection-procedure-at-boeing/#comment-509962

The "text message" is mentioned in the same paragraph as a Non-Conformance Order, so I assume it's a message on the NC Order as opposed to an SMS. I donquote:Records show the rivets were replaced per engineering requirements on Non-Conformance (NC) Order 145-8987-RSHK-1296-002NC completed on September 19, 2023, by Spirit AeroSystems personnel. Photo documentation obtained from Boeing shows evidence of the left-hand MED plug closed with no retention hardware (bolts) in the three visible locations (the aft upper guide track is covered with insulation and cannot be seen in the photo). See figure 16. This image was attached to a text message between Boeing team members on September 19, 2023, around 1839 local. These Boeing personnel were discussing interior restoration after the rivet rework was completed during second shift operations that day. The report doesn't reference CMES or SAT directly, but it does say quote:Manufacturing Records/Human Performance so I guess CMES?

quote:During the build process, one quality notification (QN NW0002407062) was noted indicating the seal flushness was out of tolerance by 0.01 inches. No manufacturing rework was required, as Spirit AeroSystems Engineering determined the condition was structurally and functionally acceptable and did not adversely affect the form, fit, or function of the installation. This is a meaning of "tolerance" with which I am unfamiliar.

Obviously Boeing is responsible for supervising its subcontractors but given the problems Spirit's having I have to figure everyone else who does business with them, which is every other manufacturer of civil aircraft, has to be shaking in their boots a little?

Maybe, maybe not. Spirit was created in 2005 when Boeing sold its Wichita manufacturing subsidiary to a private investment firm. Spirit then merged with BAE aero systems and later acquired Bombardier’s overseas factories. The question would be how operations in Britain, NI and elsewhere are affected by Wichita. Also it seems relevant to note that the other divisions don’t built entire fuselages.

Phanatic posted:This is a meaning of "tolerance" with which I am unfamiliar. “The first number was pulled out of our but so we waived the requirement rather than conform.” Actually though, I’ve seen stuff where the initial target was determined via analysis based on assumed parameters and then a later nonconformance that has actual test data gets a new limit set based on repeating the analysis but with the real data to show significant margin.

Murgos posted:“The first number was pulled out of our but so we waived the requirement rather than conform.” Yeah, you can't do analysis on every single thing, if you know a part is good at +/- 0.005" and that's producible, you just send it as a general requirement for that part. Additionally, if you tried to make parts that had widely variable tolerances, your drawings would be plain unreadable, so you spec the worst case and put some general guidelines in there. If you later find out that you have a part you need that's 0.007" in one location, you can go look and say "it's not on an interfacing surface, it's not a critically stressed area, it literally doesn't matter in that location" you can accept that part. That's not what happened here, obviously, no one did due diligence to find out WHY that door seal was OOT. Again, not the case here, but a good reason not to use unreasonably tight tolerances is to reduce nonconformances, something like alarm fatigue can happen where an engineer spends all day looking at poo poo that doesn't matter and saying "yeah, send it" until it becomes a habit and they don't investigate the issue thoroughly. This is also on the company for probably not having enough engineers, while pressuring them to meet production rates (that's inference based on most companies in Capitalist America.)

Nebakenezzer posted:So dumb question: why did they fly all the way back to Toronto? If they landed somewhere else for anything but a gas and go, then Air Canada is paying for food/accommodation/compensation. Considering how long they held for then went back, I’d suspect it’s a purely commercial decision. Cheaper to just bring everyone back to origin. And even if they landed in Gander, the only buses based there are school buses. Air Canada pax aren’t going to find that acceptable. And a coach bus takes 45ish people? So you need 4ish to accommodate a full 737. That’s hours to arrange and transport them. It would suck to be on board that flight, but the actions make commercial sense. And to an airline you’re noting but a few dollar signs. St_Ides fucked around with this message at 04:10 on Feb 9, 2024 |

Hi I’m a machinist (admittedly not aerospace) and if you can’t or won’t keep your part within +/- 50% of spec you need to get “promoted” the hell off the shop floor. I’m checking every part if it’s long run time or every 30 mins if short and you better believe I’m adjusting offsets by tenths of a thousandth of an inch as the machine reacts to temperature and tool wear changes. None of my poo poo goes into airplanes or anything else similarly critical.

You would be shocked and amazed at some of the poo poo we get from suppliers. Fluid passages completely blocked by drill points, sharp burrs on every feature... My recent favorite, a flat loving plate that looked like it had been machined using only a 1/2" end mill, out of flatness by 0.007", with "steps" in multiple locations, when asked WTF supplier said it was "impossible" to make the part flatter.
