Korean airplane crash

All but two presumed dead after Jeju Air plane crash in South Korea – video

The Boeing 737-800 skid along the runway before hitting what appears to be a concrete barrier and bursting into flames at Muan airport in South Korea.

Looks like a near text book landing wheels up until they hit a rather oddly placed concrete wall.

Only two survivors.

I do wonder why they maintained the high approach speed of a no flap landing. I feel that should have been a warning. But, the PIA 8303 flight is precedent that a pilot can be so confused about the configuration.

PIA 8303 was a 50% confusion, mainly over the question of go-around or not go-around. The pilot in command intended to land; his first officer disagreed.

I note that both 737 MAX crashes and the PIA 8303 crash were precipitated by the crew "cleaning up" the aircraft as part of their response to an unwanted flight condition for which not being "clean" was not involved in the problem in any way. I do not understand the desire to make changes to an already unstable situation.

The cockpit voice recorder from South Korea is/has been copied out and is being examined to produce a transcript and that should resolve the intention vs. confusion issue.

The flight data recorder was damaged in a way they could not attach a read-out device, so it is being sent to the US for a more advanced effort. There's no indication yet that the modules inside are damaged; the report is the external connector was separated in the crash.

I hope this can be resolved by the review of the CVR and FDR and isn't another case leaving ambiguity that could have been eliminated with a video recording of the flight deck.

It appears the South Koreans are doing a top-to-bottom analysis of every aspect of aviation, including police raids on the airport management offices.

The raid came as pressure built on authorities to establish the cause of the crash, which occurred after the Boeing 737-800’s landing gear apparently failed to deploy as it came in to land at Muan, in the country’s south-west, on Sunday morning.

I think they will find that the landing gear did not fail to deploy, but that the pilots simply didn't call for the deployment or act on it for the same reason they did not deploy the flaps or the speed brakes/spoilers. Any reasoning about why is just a matter of waiting for the CVR to be reviewed.

I don't understand either 3DDave.

I think the profile of pilots has changed significantly.

And it's continuing to change.

Some of it is airlines wanting a more compliant work force.

Some of it could also be a national pride thing.
Was talking with a buddy of mine who's stationed in South Korea about the crash earier. His opinion is basically South Korea as a whole cannot believe a pilot could make mistake, let alone one so drastic. There's still some outlets over there reporting that the gear failed on landing even though we all know better. Paired with everything else going on politically there, they're determined that the plane will be at fault.

Well the back part of the engine cover is gone on the right motor could have happened at beginning of the landing strip though, its not possible to see on the video.
The motor looked intact after the "bird" strike video though.



A normal motor would look more like this wouldn't it..



This broken one looks more like the one from the video in South Korea

 

[DirteJoe]

The thrust reverser was activated.

 

[RedSnake]

The thrust reverser was activated.

Could be, hard to tell with all the dust and shadows..



But then it doesn't look like it was activated on the left motor.



Maybe a reason to turn off the motors, I assume the plane would go in a "circle" if they had been on.

 

[DirteJoe]

That's where the theory that they shut the incorrect engine off is coming from.
It's uncertain, but has been pointed out in both videos that the #2 engine (bird strike engine) appears to be running, but the #1 engine seems to be off or powered down. You can clearly hear an engine spooled up and then powering down, but no visible exhaust from the #1 engine.

There are some great videos on YT from Juan Browne and Pilot Debrief about this.
