Another 737 Crash in Indonesia
 

This one is a -500, in the water minutes after T/O. Wondering if it will get inordinate press coverage, or if the media will try to tie it in to the max? Reuters at least pointed out that Indonesia is a not a paragon of aviation safety.

ABC morning news at least made the distinction.

Sad to hear. Very interesting to see it drop from 10000ft in 60 seconds.

Does anyone have the ATC radio of this? I'm not sure where it would be on liveatc.

I was actually watching the Air Disasters episode on the LAM Mozambique flight 470 crash by suicide, which took a dive as well from about that altitude.

Yes, RIP.

That's the last thing I'd think of, more likely spatial disorientation and/or instrument malfunction... that seems to be a recurring theme. Suicides seem more likely to occur if somebody goes to the lav and leaves the other pilot alone, I'm hoping nobody does that anymore. LAM and germanwings are both recent, both had that MO and occurred in quick succession of each other... how many case studies does it take to change the rule?

Heard reports of heavy rain in the area around the time of the crash,any possibility there was convective activity around the area they might have encountered?

Watch the playback starting at 7:38. Pay attention to heading and groundspeed.

CVR/FDR located...

Glad they are located. Sure there is an explanation as to what happened. Rather baffling as to why. Condolences to the families.

Sad. A Covid test requirement forced them off their original flight and onto the doomed flight.

"Minarni and her husband were supposed to fly home January 5 on another carrier -- Nam Air, he said.
But when they arrived at the airport Tuesday, they were informed that in order to board the flight, they would need to take a coronavirus PCR test -- a process that would delay them from flying for another two days.
Once the couple got the results of their test, they were able to rebook their flight home -- but this time, it would be on another carrier, Sriwijaya Air."

The investigation is looking at the AT. Sure hope this isn't a case of mismanaged AT failure...

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?

Apparently the CTSM failed to disconnect the A/T in a timely manner. So no indications other than lever position.

Yes. But presumably they fixated on the attitude problem.

But they screwed that one up too.

"aircraft rolled to the left at an angle of more than 45° with an accompanying by EGPWS bank angle alert. The left roll was further exacerbated by left roll pilot commands."

The previous flights and the simulator testing showed the plane could be flown out of it using just the ailerons.
They did nothing right. In the report they interviewed all the previous crews who had this happen, and most of them didn't even remember it happening because it was such a non-event. No-one even filed an asap for it likely because they didn't think it was anywhere close on being a threat to safety. Somehow these clowns ended up with a near-vertical dive at almost 500kts(over 80 degree pitch angle). The FO was completely useless as well, all he said was "captain, captain, captain".

Thanks! I couldn’t find it on the KNKT site when I checked.
