Very unusual to happen while cruising like that out of no where:
My condolences to all who lost their loved ones.
While one might initially think a problem with the horizontal stabiliser, a locked rudder can cause the same effect, which came straight to my mind, almost screaming:
Boeing has been plagued with this on the 737 before when a hydraulic power control unit reversed the pilot's input.
While the design flaw has been allegedly addressed, a fault with these PCUs both for Rudder or Horizontal stabiliser can never be ruled out.
However I wonder if the autopilot would be able detect the incorrect response and 'try out' a reversal, programmed in it's software based on past history ?

Flew in and out of Kunming in a China Eastern 737 in 2019. Certainly looks like a mechanical issue.
I'm a bit wary of Boeing since I saw that doco on Netflix regarding the 737 Max. Downfall: The Case Against Boeing
They are not the company they once were......

It will be interesting to see what black box has to say.

One report I saw said the plane dropped rapidly from 30,000ft then leveled off with a slight rise in altitude at 8,000ft then nosedived again.
There is no reported mayday or other communication transmission.
Whatever happened, it was vey sudden.

with all the safety systems in place you would think the plane itself wouldnt allow an intentional nose dive ? I would guess its a horizontal stabiliser failure

No mayday type call is the thing for me. Dropping, stablising, then diving is almost as if they (or he) wanted to crash at a particular place. That missile like dive just seems too deliberate....
The fact that there's a highway to hell and a stairway to heaven says a lot about the anticipated traffic flow.

There's nothing left of the plane, the black box will interesting if it's found.
Its possible it could have. Definitely be interesting to see the results of what data they find and if a old issue has once again returned.

I doubt they'll find them. They aren't indestructible, and that crash was about as forceful and violent as you can get....
Then, of course, you've got to be prepared to actually believe what the Chinese tell you.

True. They could save face and blame the pilot and co pilot right off the bat.

From the vision it looks deliberate to me. Seems strange that a terrorist would target a Chinese plane, though, given that China seems to side with more terrorist states than not. The levelling out could be that someone managed to gain control over the terrorist (for want of a better name) for a moment before he managed to overpower said sane person. Another argument against terrorism though is, that surely they'd have targeted a more heavily populated area to cause as much mayhem as possible. My money's on a pilot who was knocked back by the good looking hostess so decided to end it all.

Well I recall in soul plane....
Unfortunately pilot error, terrorism, or faulty avionics many died and many lives have been changed today. Sad.

Yes indeed.
The whole stabiliser(actually 2) can be controlled with an electric motor(used by the auto pilot and trim) and also purely manually with cables using the horizontal stabiliser trim wheel.
Additionally the stabiliser has two hydraulic elevators for normal flight input through the column.
That is plenty of backup for recovery if one system fails.
The reverse rudder issue would seem more likely... and pilot suicide.

Looking at the video, more like the Germanwings scenario or known rudder issue < >
Doesn't tell us anything really, which I for one, completely understand....except for the former pilot saying it's apples and oranges with the MAX. it's been f'all time. Jeeeez....the simplest crash takes time...
The crew, or one of the crew, has made sure there will be no boxes found. They are NOT indestructible. If they could survive THAT crash they would be.
Now, perhaps these things could be designed to automatically eject under certain conditions, and that would help a lot in many circumstances. But they aren't.
