Scary indeed Huh Apparently the plane had a service check only a month ago. It's the airline's second crash in a year.

That is very scary. When I first saw it, I thought someone had been playing around with some CGI.

Re: Scary Videos of Transasia Plane ditching in Keelung River

Looks like LH engine failure followed by letting the a/c speed decay below Vmca which is the min speed possible to maintain control on one engine (which is a higher than the stall speed).
One engine is usually the critical one on twin engined a/c depending on which way the props rotate so Vmca is different for a LH or RH engine failure.
(unless you have counter rotating props with counter rotating engines on either side)
Aircraft looks semi-stalled as it approaches level then there is the left wing drop - which is sort of incipient spin entry into a full spin had the ground not intervened.
Swept wing transport type a/c do not stall in the traditional way on light aircraft by dropping the nose  - they tend to just pancake down in a level attitude slightly nose up
Possibly a failure of the auto-feathering of the prop pitches on a the failed engine (I'm assuming left here) giving them a huge amount of drag etc on the left then badly handled might have put them in the no-exit out scenario.
You see, even if they had enough/infinite power on the other engine it simply does not work if your speed is too low (<Vmca) as you run out of aileron and rudder to correct the yaw from the failed one and the aircraft flips/rolls and crashes. So once you let the speed decay and you have no altitude left to put the nose down you have no exit.

BBC report on tv this a.m.  stated that both engines " failed" just after take off.... however... my info on Flightradar 24 is saying that engine number 2 failed first... then engine number 1 was stopped...
further reports on flightradar24 say that the black box flight recorder indicates similar states... indicating that the pilot ( or someone ) shut down number 1 in error ... causing the complete loss of power.

Aviation Safety Council: Engine #1 was cut off manually after trouble with engine #2

Black box data indicate that pilots may have turned off wrong engine & lost all power 1 minute after take off

Oh deaaarie me
It could be pre-conditioning in that there was apparently some disquiet about No 1 engine prior.
So when an engine fails they automatically think No1 has finally gone when actually its No 2.
But how on earth did they miss the cues - the aircraft yaws towards the failing engine, you apply rudder to correct the yaw and then use the rule of idle foot (on rudder pedals) is idle engine to confirm - not to mention the instrumentation - assuming this had not been in error cross wired to give the wrong engine as failed!
It should be easy on takeoff when the power is maximum so the yaw is significant. (less easy on lower power approach as the Kegworth/East Mids/BMI crash proved)
So that explains why it looks semi-stalled wings level on the video: very little engine power - then something happens - who knows possibly them trying to de-feather the props on No 1 to make it re-start to increase the drag significantly over the left wing as the speed by now is so low as to make the LH wing instantly fully stall so it drops fast.
The presence on board in the 3rd seat of a check/inspector captain might have made it worse if there was a "disagreement" - too many cooks in the kitchen scenario etc plus the fact that when one is being "watched" you tend to make mistakes that you would not when on your own.
