Listening to the NTSB...
Still haven't located the door plug. Have found 2 cell phones
3 lap children

CVR circuit breaker was not pulled, and was overwritten at the 2 hour mark. Now she's off topic and editorializing against the FAA for not mandating 25 hr CVRs like Europe.

She also praised the flight crew earlier, though they have not been interviewed yet (she didn't say they have been).

My first thoughts... She's in charge???

Oh... Previous issues were an illumination of the Auto Pressurization light that was remedied by selecting an Aux setting. The incident plane has been derated/restricted for no ETOPS (No extended operation on single engine, no flights to Hawaii which is more than capable of).

What's your objection

Just fist impression...

A lot of uhhh s and ummms. Not a smooth public speaker for someone giving a press conference.

It also struck me as odd to praise the flight crew (regardless of merit) early in an investigation. I'm not implying they did something wrong, but I would think use caution regarding praise of parties that haven't been interviewed. And yeah the flight crew failed to pull the CVR CB for evidence preservation.

I also found the editorializing about CVR recording time to be inappropriate for an accident investigation PC. But I guess she's got an audience with reporters so...

Oh... The seats by the plug were torqued in their mounts! The decompression also blew the sealed cockpit door open and sucked a checklist off the dash.

The flight crew apparently did a good job dealing with an explosive decompression. You're trying too hard to find fault. The plug door blew out.

Sorry..
3 lap children were on the flight.
Added editorializing there too for pax to use car seats.

The NTSB never misses a chance to complain that the FAA (or some other agency) hasn't followed their recommendations.

She is not a good public speaker. I've seen some of her other times she's been with the Go-Team and public speaking is a skill she sorely lacks. They really should keep her back in D.C. and let one of the others do the job. Also, she isn't in charge of the investigation. One board member travels with a Go-Team to act as basically the spokesperson to the media.

Not trying to find fault or lay blame. Just my impression while listening live.

To Rapiers comment above... Do they not have a PIO?

Found it. It was in someone's backyard. Must be a pretty big backyard.

Press Conference ends just before 9pm Pacific and they find the door afterwards.

Odd.. but ok. Glad they've found it. Edit... Odd that someone was outside to find a door in their yard at that time of day.

Yeah I just realized we have two of these threads now for some reason. Whatever. Good news.

Alaska 737 cockpit voice recorder data erasure renews industry safety debate https://t.co/K4QGTzVcv6 pic.twitter.com/Gjh8dHEkoK

The plane entered revenue service on November 11th, its first trip was a PDX-MCO turn. It flew 49 revenue flights between then and 11/27 before going to OKC for 10 days. 12/7 was the day that it left OKC where AS has MRO work and WiFi installs done by AAR, and was the first time there were pressure warnings on the plane. This maintenance probably involved removing the plug for installation of their WiFi systems, and then re-installing it.

So it might be maintenance-related after all, as the airline-furnished (by a contractor in OKC) WiFi was added not by Boeing but after delivery/operation for a couple months by AS. No video/images of the door yet that I can find, but it is unlikely to have been manufactured incorrectly I would guess, it just wasn't re-installed correctly/safely, and/or was damaged while removed.

Anyone decipher how this is secured? Looks like internally there are some form of bracket on top... don't see one on bottom. Then it has these little bolt locations. Seems like the interior bracket failed in some way.

---

What keeps the skin on the frame? Shouldn't there be a pressure surface on the inside of the door frame?

My assumption was that the door has part of the skin as a lip around and it seals against the body with bolts in two axis. One to pull it against the door z-axis and one in the corners to go x/y.

But it sounded like there are only 4 bolts x/y in the corners?

Two bolts in the bottom utilize the hinge pin attachment points that the regular door uses at the bottom. Then two bolts nearest the top in place of the door latches.

When it's used as a door it doesn't swing like the doors used for standard ingress/egress. It's an event exit only and flips out rotating around it's X axis.

Watch the video that Nortex posted on page 4. He explains in great detail how all of the configurations work.

I had flights to and from London last week....
All children on the plan were good with no crying.
I would rather ban fat people that spill into other seats and smell bad.

But back on topic....
I think Alaska is having growing pains as they're trying to expand their network and the maintenance team hasn't been able to scale up.

Also now that every airline is a credit card company that happens to fly, maybe priorities aren't where they should be.

For the record as well British airways didn't have any in-flight announcements about signing up for their CC.

How does it hinge and swing down when the airframe has all of those alignment points that would seem to impede it?

Im not completely certain. The plug I think lines up inside those 12 alignment points. Watching that video left a bit confused. I'd like to see a video or an animation of the process.

In the video he has a photo of the plug "opened" and held by cables at about 15degrees. But... How it moves into the closed position for bolting/securement I don't fully understand

Plug has been found

NTSB has recovered the door plug from Alaska Airlines Flight 1282 Boeing 737-9 MAX. NTSB investigators are currently examining the door plug and will send it to the NTSB Materials Laboratory in Washington, DC for further examination. pic.twitter.com/fqeemNeBPW

Sure doesn't look like the plug section itself blew apart, must not have been secured correctly after the maintenance, imho. Gonna guess…cotter pins? Torque wrench?

shame they didn't post photos of the other side of the plug. I assume that was intentional....

haven't seen this posted yet...

The MCAS was required because the new engine designs required the engines to be placed higher and more forward. This requires a righting force (through wing trim) that wasn't necessary compared to previous designs. The MCAS is a complexity risk, but it could have been done so more robustly and with more than just a smidge of extra training.

MCAS shouldn't be relying on one single sensor to input fly-by-wire changes. They didn't have to go full 3+1 space shuttle style computer voting systems, but my gosh is there a large middle ground here.

Just reach in there and hand tighten it with your fingers. That should be good enough...

Someone in the maintenance crew is going to be in big trouble.

I am curious if the UA Max9's involved also had IFE (WiFi) equipment installed separately, by AAR in OKC, or other BFE (buyer furnished equipment). Not trying to goal-tend for Boeing, just curious how that could be synced with what we know about the AS plane's maintenance history and the problems on it starting the day after it returned to service from OKC...
