Prelim sounds like mismanaged AT failure...

Not trying to heavily armchair QB, but this plane seemed very flyable. With one engine & some flight controls(hydraulic assisted) one should be able to get back to a runway. They may of had much more than that. No I wasn’t there, so WTHDIK.

Could it be something like China Airlines Flight 006?

I would recommend not reading a "news" article if you want good information. They tend to leave out the boring details, and the details are important.

There was nothing wrong with the engine. It was the Auto Throttle malfunctioning. Here is the report, it is missing some key information, but they can get away with that in a preliminary report.

PK-CLC Preliminary Report.pdf (dephub.go.id)

"Complacency" sounds better than incompetence. The autothrottle pulled the other engine down to 34% while the other engine stayed at 92%. This led to loss of control.

I wonder how these clowns would have handled an engine failure.

They might have had some bells and whistles to wake them up in that case. Sounds a bit like the typical overseas tendency to try to fly out of UAS with the automation.

Obvious failures in basic airmanship, but an un-annunciated rollback (on one engine) isn't a good thing either.

Is it an un-annunciated rollback if the other thrust lever is at max thrust and other at idle? Also the A/T disconnected which (I believe?) causes a bell or a whistle.

All they had to do is push the thrust lever up.

Is there a link to the final report?
