I was in Portland at the time of #AS1282. Miles away, I was unaware until later. A concern looking at the flight track is debris could have fallen on western side of Portland metro area.

Boeing CEO says company is "acknowledging our mistake" after Alaska Airlines door blowout
The door plug of a 737 Max 9 blew out during an Alaska Airlines flight, just minutes after the plane had taken off from Portland, Oregon.
My concerns were valid about #AS1282 debris falling on Portland metro area. Based on this article in The @Oregonian, I plotted the general area on a map where the door plug was found in residential backyard. Cell phones fell nearby. https://www.oregonlive.com/portland/2024/01/door-that-fell-from-alaska-airlines-flight-found-in-a-backyard-officials-say.html #aviation #travel #avgeek

It has already been 6 months (yesterday) since Alaska Airlines 1282 blew out a door over Portland on January 5, 2024.

A panel that blew off a Boeing jet will get star billing during a Washington hearing
A panel that blew off a Boeing 737 Max during an Alaska Airlines flight will be a key part of a two-day investigative hearing set for next week. Federal investigators have been examining the mid exit door plug since not long after it blew off during a Jan. 5 flight, when the plane was at 16,000 feet. It was discovered in the backyard of a home near Portland, Oregon. National Transportation Safety Board personnel displayed the panel for the media on Tuesday at the NTSB’s laboratory in Washington, D.C. A preliminary report found that four bolts used to help secure the part were missing when the plane rolled out of a Boeing factory near Seattle.

Anne Ominous@ikluft real cool that our regulatory bodies have basically no power. i seriously wonder where all this will even lead. bc i can pretty much guarantee anyone that the US govt is not going to be nationalizing or breaking up any corporations anytime soon.
as my bud was saying the other day - the NTSB can only 'make recommendations'

OldFartPhil@ikluft @jonostrower There were more than four bolts holding the plug in place. It took multiple flights for the whole assembly to weaken enough for the plug to dislodge.
J. Steven York@ikluft @[email protected] @jonostrower
The door wasn't actually held ON by the bolts. In fact, the door (or plug in this case, it held on to horizontal pins that the door hooks over and downward into the installed position. The bolts keep the door from lifting up to clear the pins. Without the bolts, the door was kept from moving out, but there was nothing to keep the door from sliding UP and eventually releasing the pins. This could have easily happened before pressurization, as in hitting a bump in the taxiway, though there would be a tendency for the door to fall back into the fully locked position. This is probably how the door created those pressurization warning lights that miraculously seemed to fix themselves. As they cycled the pressurization, the door was free to fall back. Once the plane was fully pressurized at altitude, it would be tightly sucked against the opening, and would have been hard to move. My guess is, there was some sweet spot, where the door was loose enough to move, but pushed outwards far enough to stick in position when lifted. It would be like a booby-trap that reset itself every time they landed and opened the plane. But one day it moved just a LITTLE too far.

@ikluft was chatting with some guys and we decided Boeing might consider changing their name to Wing and a Prayer SMH!
@User47 This was a serious goof. But at least now we know when and how it happened. Human error from forgetting something is routinely dealt with by checklists and cross-checking/reviewing work. So actually we can have confidence they'll be able to resolve this so it doesn't happen again.
The scary thought to me is, although the seat next to the door plug was empty on AS1282, how many people sat next to it on prior flights? They would likely have died if it happened on their flight.
@ikluft how many other egregious whoopsie-doos exist? 🙁 and where are all of the problems with the planes the “lazy” French build 😂
@User47 Airbus has had problems too. Each had pilot-override crashes after adopting fly-by-wire: A320 was Air France 296Q in 1988, 737Max was JT610 in 2018 & ET302 in 2019. Airbus had recent quality issues with A350 paint & composite delamination - settled in court but lack transparency whether it's really fixed yet. Airbus had an egregious user interface problem with AF447 2009 where pilot inputs didn't mean what FO thought when control law changed, other pilot got no warnings about conflict.
@User47 We really need to focus on finding root causes of problems, including systemic and human factors behind some. Solve those with procedures that will prevent them. It works.
The door plug blowout is triggering talks betwen Boeing & Spirit that they needed to have about working more closely together. But Boeing really shouldn't have spun-out Spirit to start with.
Derekodon@ikluft I would venture that no aircraft in the skies right now has been more inspected/certified. If anything, I’d be happier on a Max9 than any other choice.
But bottom line, it is still a fact that the most dangerous part of your travel day is getting to and from the airport.
@DWTSquawk7600 Also, we don't yet know from NTSB what the pressurization problem was with AS1282. Inspecting for loose bolts is a prudent preliminary action. But if it was overpressurizing the cabin, that could have been a plausible cause of the door blowing out. If so it could necessitate inspecting the remainder of that brand new plane's fuselage for cracks as if it was an older plane.
Errol Cavit@ErrolNZ @JetTip There hasn't been an official conclusion from NTSB yet. But the #AS1282 incident intuitively cast doubt on the installation process of the 737 Max door plugs. (Now also the identical ones on 737-900ER.) If you let your imagination run away with "all processes must be reviewed", very quickly there wouldn't be resources to do all that. We started with one data point about the door plugs, plus what inspections find. Nobody wants that to happen again. So that's why it gets priority.
