Rather scary video

Somewhat surprisingly the majority of the passengers appear to have survived

Probably same video but not blocked by BBC https://www.youtube.com/watch?v=eJNAx4BsUtE

Very similar. BBC video is from the car in front of this one, but not such good quality.

Somewhat surprisingly the majority of the passengers appear to have survived

It sounded too good to be true
Now reporting 23 dead, 15 survivors, 20 missing

Parlour talk: It doesn't look like it's out of control from asymmetrical thrust.

Also of note: The weather seems unremarkable.

Now that it's at the 24-hour point, it's time for an ITS-analysis.

Cheap composites probably have a limited role in the major structural components. The cabin survived fairly well as did some of the passengers.

Fly-By-Wire systems that mask classic aerodynamic behavior are not involved.

The aircraft was not equipped with a Ballistic Recovery Parachute.

However, the aircraft is designed and made by Frenchmen.

However, the aircraft is designed and made by Frenchmen and Italians.

Fixed

...so it appears to be the classic one engine quits, and in the hurry to feather and secure, you shut down the good engine.

I guess we need more guarded switches.

From Wikipedia:

On 6 February, investigators revealed that there had been no engine flameout; rather, the right engine, for which the warning had sounded, had switched to idle mode. Subsequently, the pilots cut power to the left engine.
Cockpit voice recorder

The following data is selective CVR data released by the investigating authorities on 6 February (all times local):

10:51:13 — Received take-off clearance
10:52:34 — Tower asked pilots to contact Taipei Departure
10:52:38 — Warning sound recorded
10:52:43 — Crew cut power to left engine
10:53:00 — Crew discuss checklist of turning off an engine in flight
10:53:06 — Crew discuss cutting power to engine number 1 (left engine) and confirm engine number 2 (right engine) is idle
10:53:13 to 10:53:19 — First stall warning
10:53:20 — Crew said engine number 1 is feathering and has power cut
10:53:21 — Second stall warning
10:53:35 — Crew issues "Mayday" call with a message of "Engine Flameout"
10:54:09 — Crew calls for restarting engine multiple times
10:54:34 — Second master warning
10:54:34 — CVR records unknown sound
10:54:37 — Stops recording

The authority made a preliminary determination that it was engine number 2 that went to idle/feather by itself and caused the first warning sound at 10:52:38.3; the crew cut power to engine number 1 at 10:52:43.0.

Ay, caramba!

[ocelot]

That's ... interesting; they confirmed that #2 is idle and are talking about shutting down #1 and it didn't occur to either of them that this is a problem? O_o

Apparently standards haven't been what one might like though:

Preliminary report out

http://www.asc.gov.tw/main_en/docaccide ... acd_no=191

"10 54:27 PF said “wow pulled back the wrong side throttle” while aircraft was at 309 ft. with speed 105 knots."

[monchavo]

The Guardian rather dryly noted his fate

"Liao was not among the 15 people who survived."

[Not_Karl]

Final report is out. AvHerald article (links to final report in first paragraph).

Something to be said for the old fundamental:

1. Warning
2. Don't touch anything
3. Light cigarette
4. Do exactly as commanded by the captain...do not ask questions
