This was an accident that was rushed, and appears that they never preformed the emergency checklist. Had the emergency checklist been used it would have taken a long time before a landing attempt. As a former airline captain I would have continued the first landing approach with a fully configured aircraft as the safest landing with either engine still producing power. This looks like a failure of their pilot training and standards by this airline.

Great lesson here. When you are stabilized on final and an engine quits, don’t touch anything unless you absolutely necessary. Bump your speed if necessary and reduce flaps if necessary. In the Airbus you don’t have to touch anything. Just land straight ahead. Let ATC know to roll the trucks and silence the bell. This happened to me in a 757 when I hit a flock of geese. The right engine ate it and was fine. The left engine lost 4 blades but kept running. Good ole Rolls Royce.

Wrong engine has been the leading explanation since day one.

[isilder]

It was panic at every moment. Abort landing in panic. Shutdown wrong engine in panic. U turn in panic. Touch down in panic

From the video data -
Fact 1: The right engine suffered a bird strike. At a minimum it had reduced power. The fact that the air brake on the right side was partially deployed, the engine was putting our some power. This slowed the airplane a small amount.
Fact 2: The airplane had plenty of power to make the go-around and make a second chance at landing. Therefore, the left engine was putting out full power at that time. But on the ground it was off. There was no power at all from the left engine during landing. There is only one possible explanation, the engine was turned off in the cockpit. My first guess is that it was turned off inadvertently. I will bet that poor layout of cockpit was the primary reason the left engine was shut off.
Fact 3: The engine blades fully verify that: A - the right engine was bird strike damaged and damaged partly by the impact. The center of the blades is slightly off center. But not a lot. B: The left engine was not running on impact. The blades are fully intact and the center shaft of the engine is in full alignment with the rest of the engine. The cowling on the left engine is pushed down and that is consistent with engine off and hitting dirt on the bottom first and then the concrete wall.

Summary: The left engine was running until moments before touch down. At that point it was turned off. No explanation for this, except possibly poor design of the cockpit controls. The right engine was running at greatly reduced power when the airplane landed. The fact that the wheels were up speaks volumes to pilot and copilot overload. There are checklists that are to be executed and take some time to execute. This time to execute check lists is far longer than the time used to make the go-around and land belly up. Therefore: The pilots were trying to execute a emergency check list and were completely distracted from normal landing procedures. Thus the wheels were up. Thus the airbrakes on the wings were not deployed. Thus the flaps were not in the landing position. The brakes on the wheels are the primary means for stopping the aircraft. The reverse thrust requires the engines to have full power. There was no reverse thrust from the left engine - it was off when needed. The reverse thrust on the right engine was partial - and likely very low from bird strike engine damage. The bottom of the plane is smooth and offers little slowing force. The slight nose up attitude means that 2 more effects were in place. Ground effect is very strong at belly on the ground and nose slightly up. In addition, the nose up added lift form the wings. Therefore the force on the belly to slow the aircraft was greatly minimized.

As a consequence of a long series of this and then as a result that: The aircraft hit an immovable object at very high speed, the concrete wall. At that point it was game over for everyone except two in the very back who were facing the rear of the plane. That fact increased likelihood of survival by at least 5 times. RIP to all who died. Condolences to the survivors.

I will readily admit I may be COMPLETELY wrong with my opinion, and that's exactly what it is, an opinion. But as a licensed A&P mechanic that has worked on CFM's since they were invented, I have some questions and observations. First, from what I can see in grainy photos, there appears to be no heat plume coming out of the #1 engine, but the #2 appears to be making thrust. It also appears the TR C-ducts have partially transitioned on the right side but not fully open. If that's the case, the blocker doors may not have fully reversed the fan-air. It reverses the 80% by-pass air, not the 20% hot section, so it's hard to tell if the TR is kicking up dirt or it's exhaust from the core.

From the pictures I've seen, the left side TR's were fully closed. So my question is, did they inadvertently shut down the wrong engine in a panic? That would explain the TOGO, flaps, slats, gear up, and no spoiler-boards and that failure to fully climb out and circle back around with time to refigure the aircraft for a single engine approach. From the photo you showed of the left engine after the crash, it appears to me the fan wasn't turning when it struck the ground, based on the damage done to one side of the blades.

I'm just thinking out loud, please don't throw rocks! Until the FDR and CVR info is released, just chock this up to "Things that make you go HUMMM"

[charlestoast]

Sadly, all indications are that this tragedy was caused by a series of catastrophically bad decisions made by the flight crew. They should havecontinued their stabilized approach and landed on runway 01. The Korean authorities have made things worse by inferring the problem might be with Boeing, CFM or Jetu maintenance, and it will be very hard for them to not look foolish when the facts are made public. There will be massive lawsuits, and an emphasis on crew training and CRM.

[randyg]

The short answer is yes. A shut down of the wrong engine is the best explanation of how the aircraft ended up where it did. It isn't the only possibility, but it is the most likely.

The initial go around shows that after the bird strike they had enough thrust to climb out, hydraulics to retract the flaps and at least some electrical power. Which would all be consistent with severe damage to one engine, not both.

It is possible that both engines did take birds, but one was in good enough shape to conduct a go around.

One of the very few reasons to land an airplane immediately with no gear and no flaps is because you are forced to by loss of thrust on both engines. One due to severe damage from birds and the other... well it wouldn't be the first time that someone shut down the wrong engine during an emergency.

The landing without gear and flaps is harder to explain, but it does line up with loss of thrust on both engines. It requires that the normal operation of gear and flaps were both unavailable. Meaning both the electrical and engine driven hydraulic pumps are not operational. There is a way to electrically lower the alternate flaps but it is slow and is normally done with a non normal checklist. The gear can be lowered by gravity and airflow by releasing the uplocks which again is normally done with a non normal checklist.

Alternately, both engines could have failed due to birds. One right away and one later during the go around. I think this is less likely especially after seeing the front fan of the left engine.

This is purely speculation based on the limited evidence i have available to me.

[MrSuzuki]

What you missed about the right engine is that there are fan blades MISSING! But no blades missing on the left/good engine. These clowns shut down the wrong engine due to a lack of cockpit discipline. Real professional pilots always verify with the other pilot that they are going to shut down the failed engin and not the good one. This is done by slowly pulling the throttle lever back on the suspect engine to see if nothing happens, which verifies they have identified the failed engine.

[RobertoHernandez-rqbf]

If you have a partial power loss on final during a stabilized approach, you should land your plane and tell maintenance engineers to find out what the problem was; you don't make a test flight with 183 people on board.

[drfirechief]

This isn't the first aircraft disaster in which the pilots shut down the wrong "undamaged" engine. It fits all the circumstances. The other aspect, is that is some countries they don't have to same cockpit discipline as others. Where some countries it's absolutely a shared cockpit and in some it's the "I'm the pilot and I make all the calls" environment. which cuts your pilot input by half.

[rpsmith]

Bird strike followed by multiple pilot errors! No reason for anyone to die on this flight!

[leokimvideo]

A rushed panic landing after a bird strike, tired crew who threw the checklists out the window. Nothing deployed for a landing and the sound of a jet engine at full power as it;s skidding down the runway. Little or no deceleration to be seen. The engine thats set to reverse thrust showed no signs of exhaust spilling debris as reverse thrust does.

[danielcgomez]

just for information ...an engine that is not 'producing thrust', would unless damaged in some way that stops it from rotating, will in fact be 'wind milling' ...so, it would still be rotating, just at a lot slower speed than an engine that is producing thrust. I'm not discounting your observation, just informing viewers who may not understand some details. Thanks for your update.

[andrewtaylor]

If you look at the right engine you see dirt and mud deep into its core. It was still spinning when it reached the grass at the end of the runway, and drew all the dirt deep into itself like a boring machine. That means the engine was running. The Left engine looks clean except for some dirt on the front of the forward fan blades. That engine was dragged through the mud. Its turbine was not spinning. The left engine was probably shut down.

[mtnjghz]

The exhaust signature was from the right engine not the left.

[reefkeep]

Like I said before, this will come down to pilot error sorry to say, but the concrete was the final straw.

[Sacto]

This is why JEJU Air _really_ needs to look a their cockpit resource management (CRM) procedures. Was there a situation where the flight crew didn't get enough emergency training and ended up panicking when the bird strike happened?

[GermanGuy]

As an ATP rated pilot who started flying gliders almost 33 years ago, I firmly believe that they had less power than one undamaged engine could provide. If they switched the left engine off by mistake or it stopped working for other reasons will be known shortly.

[Nick_the_Gold_Bach]

Good spot on the engine photo - saves rest of us our bleary eyes.

There must be thousands like me waiting to hear what the FDR reveals and the CVR indicates pilots intended to do.
