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.

Seems to be a epidemic.

 

[RedSnake]

But this is not a Boeing but a de Havilland Dash 8-400 (twin-turboprop) (DH8D)

Another "bird strike" while cruising followed by a long diverted flight after calling an emergency AND an apparent loss of hydraulics. This reads exactly the same as the airliner that was just shot down.

Edit: I had previously read that the flight was on route to Daxing Airport near Beijing. That appears to not be the case and I retract my above comment.

 

[LittleInch]

This is a longer video

Looks like they had a bird strike on the original attempted landing on 01, did a go around onto 19, then put it on the ground half way down the runway, no flaps, slats or air brakes and then ran into a large mound holding some landing localsers. All very odd as to why they were doing a wheels up landing.

 

[RedSnake]

Well I saw video of the "bird encounter" can't see any birds just what looks like a white smoke puff coming out from the back of the right engine.
Not sure how this can impact the hydraulic system as they said in the beginning so that the landing gear stops working.

Well here it is..

This by manner accounts seem quite an avoidable tragedy. There are multiple confusing aspects of this disaster both in airline operation and civilworks on the ground.

A good early summary here:

A good view of what the airplane hit here, which seems to be an earth berm covering a significant concrete wall or footing. (It might have been a wall that was then ramp by surrounding by earth.) Either way there was thick heavy reinforced concrete for a small plastic antenna array.

Yes my first thought why do they have a solid wall thing at the end of the runway its kind of made for disaster.
If there had been several catch net like on a aircraft carrier more people would have survived.

I think you are a little out of touch on reality here. Catch nets like on aircraft carriers? Care to explain this in more detail how you think it'd work?

 

[RedSnake]

Care to explain this in more detail how you think it'd work?

I understand that one of those catch nets would not have done the job since there are several more tons with inertia to brake or slow down compared with a fighter jet.
But, I said several, and what's needed is just math.

What I meant was that the pilot did a good job with the emergency landing you might say perfect, but couldn't brake, so if the plane had been allowed to continue without any obstacle on the way it would have stopped by friction on its own the only other way is to slow it down with external means.

They what are called rag wires and are common in most out of Arlanda Swedish airports due to them having dual use military and civilian traffic.

Reds local airport has the nets I think and they will be tested once a day.

That's not the end of the runway at the top of the picture, but a crushable material designed to snare the landing gear and stop the plane like those gravel run-off lanes for trucks. Between the speed and ground effect the plane was nearly flying at a very low altitude. Even with a tail hook, that would have been pushed up into the fuselage by skidding, that plane would not be stopped.

 

[RedSnake]

Even with a tail hook,

I have never talked/mentioned a tail hook.

The main cause of this tragedi in counts of human lives apart from the hydraulic on the airplane being made unoperational which was overcome by the pilot, is this solid wall/barrier at the end of the runway.

 

[3DDave]

RedSnake - Aircraft carriers use tailhooks, not crash nets, to stop airplanes.

The main cause of this was ineffective bird management at an airport surrounded by bird habitat. Maybe don't build a runway inside a place crowded with birds.

 

[RedSnake]

Yes aircraft carriers uses tail hooks when it's possible when not crash nets.

 

[3DDave]

I am aware. There aren't any deployable nets at airports.

The frangible runoff surface is always deployed to stop aircraft exiting the end of the runway, acting as a crash net.

 

[LittleInch]

Well a single bird strike shouldn't bring down a plane.

Many issues look strange here, especially the lack of flaps and landing gear. They also seem therefore to have come in very fast, floated for a long time due to ground effect and just ran out of room to stop given the lack of braking or reverse thrust and not much spoiler / air brake action if any.

Hopefully the CVR and FDR both kept running or we're never going to see what happened.

This is only used when the tailhook will not work

Set Up Barricade Net & Emergency Landing on Aircraft Carriers​

I would be surprised if this would catch the various large commercial jets (737 and up).

The following is an addition to the above post.

AP has just posted a report that contains this statement '

New acting President Choi Sang-mok on Monday presided over a task force meeting on the crash and instructed authorities to conduct an emergency review of the country’s aircraft operation systems.
“The essence of a responsible response would be renovating the aviation safety systems on the whole to prevent recurrences of similar incidents and building a safer Republic of South Korea,” said Choi, who is also deputy prime minister and finance minister.

If Korea is able to successfully investigate this accident in the midst of their current political turmoil, I am cautiously optimistic.

It's still very unlikely there was a hydraulic system failure that led to this. The plane was flying just fine, control surfaces functioning, etc just before landing. Had there been a hydraulic system failure, the go around likely would not have gone so well.

There are electric and gravity assist backups for the landing gear; something else was going on. Cabin smoke with pilots thinking there was fire? From the videos we know the cockpit was not full of smoke.

Hate to say it, but my gut feels this was almost an intentional crash.
Perhaps a failed go-around with the thrust reversers activated by accident being more likely.

How do you design a system to stop a 150mph airliner that has not touched down until there is nearly no runway left? Tailhooks and nets wont do that.

Flight 9525 would be a bird strike by today's standards of belief and reporting.
