Employees across Boeing face sweeping layoffs this week

Boeing plans to cut 10% of its workforce. Employees learn their fate Wednesday. Non-frontline workers are targeted though engineering and production won't be exempt

Dominic Gates so likely correct.

Another issue, and nothing said to the pilots.

The rate its going it will be a separate type rating.

FAA team recommends Boeing MAX design change and pilot notification

An internal memo recommends a design change to fix an engine risk on the 737 MAX, in addition to informing pilots of the risk and changing takeoff procedures.

And it might be a retrofit AD back to the MAX8 and 9.

From what can find out.

I remembered these load disconnects on the turbo props. Jetstream had them and so did the Q400. Presumed the A220's PW1500G had them as well. They do but also it's not documented for A320neo. Apparently they are not in old school jet turbine engines.

So it seems to be required feature for geared fans.

Now to my knowledge there was no automatic shut off of the bleedair system on the turboprops with the pressurisation system.

A220 and A320Neo. Again we can't find any documentation on it. But both types the bleedair and pressurisation and aircycle packs are fully digitally controlled. Alternating primary channels, backup channel, emergency channel, if one side fails completely the other side takes over. The whole lot is linked in with the fire alerting and ecam system. So I wouldn't be surprised if it exists.

On a side note just for a bit of fairness both bird strikes were outside the certification standards. One was an adult bald eagle.

And a report I read about an A340 hitting an albatross in the cruise over the Pacific there was smoke in the cabin as well.

The American pilots unions are involved with this further investigation I believe.

From what I can tell the system is basically analogue from the early 80's on the 737 series. It's going to be a pretty huge system change. Putting over a year onto the 10 being certified if they start tomorrow .

Ditto, the internet is less than helpful with this idiom

It's not over yet...

"A United States federal judge has rejected a deal that would have let Boeing plead guilty to a felony conspiracy charge and pay a fine for misleading US regulators about the 737 Max jetliner before two of the planes crashed, killing 346 people.

US District Judge Reed O’Connor in Texas on Thursday said that diversity, inclusion and equity – or DEI – policies in the government and at Boeing could result in race being a factor in picking an official to oversee Boeing’s compliance with the agreement."

US judge rejects Boeing plea deal in fatal MAX 737 crashes

Ruling creates uncertainty around Boeing’s criminal prosecution in connection with development of its bestselling plane.

Wild, I don't think it was even a year ago that most here were denying that DEI even existed.

 

[3DDave]

No one denied it even existed. The denial is that DEI has caused corporate downfall.

There's no DEI in the management of UHC, right? Well, maybe in DEnIal of claims.

 

[Brian Malone]

Yes, as 3DDave has pointed out there was no saying DEI did not exist. It just is not the cause of the corporate and engineering failures. DEI is just a different wording for affirmative action and it all can be nice statements made publicly but not acted on in any substance. Regardless, whether the policies are really implemented, Boeing's failure (s) were caused by poor engineering and business practices by non-DEI executives and as 3DDave has also made convincing arguments: unfortunate poor piloting or action choices by the crews of the ill-fated flights. Look at the history of the Challemger solid rocket booster failure (Allan J. McDonald's "Truth, Lies, and O-rings") and compared to Boeing's woes and similar themes show. Non-DEI engineers either choosing a bad or questionable course of action or being forced to take a course of action. The principals are all long-term industry insiders who are generally well respected in their field and generally are white, middle-age males. I am not pointing that out as a bad thing. It is just the elephant in the room for all of you who keep harping on DEI this/that is causing engineering failures. Do I need to point out Denney Pate and the FIU pedestrian bridge?
