JEJU Air 737-800 Crash Muan, South Korea 29 Dec 2024

[@texas737pilot]

18 year 737 Captain here. Nice analysis Juan. They rushed this approach for unknown reasons and failed to drop the gear or extend the flaps. I can’t foresee any reason for this except if you think both engines are failing. Even then, you can drop the gear quickly and electronically extend some flaps. This accident is why I won’t fly on any airline with non-western trained pilots. As a human factors instructor (formally known as CRM), there have been way too many avoidable crashes with Asian crews. Usually due to the FO refusing to speak up to an authoritative Captain even when they know a bad outcome is likely. In the west, we learned these lessons the hard way and started teaching CRM and empowering the FO to speak up.

[@jackfrench3324]

CRM = crew resource management In the nuclear power world we picked up on the airlines training method and learned that a good manager will be open to input from from every crew member.

[@grantp4022]

Well they like dictators over there :) Why question authority ?

[@swampfoot]

Definitely a cultural aspect to this. When I was an instructor at Mitsubishi Aerospace, we taught promising people to build wings and center fuselage for a couple of bizjets. Students from Philippines, India, Pakistan - all had the same reaction to my asking yes/no questions of them on a one-on-one basis - they ALWAYS answered "yes." Regardless of their understanding of a process just described or demonstrated. "Did you understand?" Answer was always "yes" even when it was clear they did not grasp it yet. They were afraid of saying "no" to anyone perceived to be in authority. I had to spend some time explaining to them that it was okay, even encouraged to say "no" or admit you didn't know something. This is a nut to be cracked if you want safety in aerospace everywhere.

The FO not speaking is a cultural issue that caused a Korean crash several years ago.

[@GrassBandit]

Do you think there is any way they just completely forgot to put landing gear down??

[@Johnnycdrums]

Jaun seems extra agitated and perplexed about this one.

[@TeamOdiffat]

@@GrassBandit its possible. Read somewhere that they expidited the landing due to smoke in cabin but that is not from a good source. Since they landed with what seems to be no flaps its more likley that they for some reasond had hydraulic issue since no pilot would manage to forget both flaps and gear for a landing(its ofc possible but the high speed would be obvious and they would see that the config was wrong). But its speculations only the investigation and black box/atc transmition could clear it up any further.

[@TeamOdiffat]

also dont forget that the 737 have a backup system for flap extending wich uses an electronic engine to drive the flaps. Its slow but works. That indicates that they forgot about it and or skipped checklist becasue as stated that 7 min period is most likley not sufficent to run checklist.

[@FutureSystem738]

Another 35 year retired airline captain with well over 10k hours on various 737 models including the 737-800 here. I concur that Juan has done a great job with the very little we know with this so far, but there’s so much odd, really head scratching stuff here, that is very difficult to explain. I sure hope the CVR (cockpit voice recorder) and FDR (flight data recorder) can fill in all the holes. (I especially don’t understand why the rush to get on the ground again if the aircraft was able to do a missed approach on the first attempt.)

[@steeloisgombo]

As a Korean, this accident is truly tragic. It is truly regrettable that the government took the measure of pouring reinforced concrete under the localizer to save on the cost of localizer maintenance due to typhoons. It is a national disgrace to have taken such a dangerous measure at Muan Airport to save a few pennies.

[@t5ruxlee210]

Very true observation. Mounting an ILS array on an elevated poured concrete pedestal at the end of a runway and then trying to disguise this deadly fact by surrounding it with a fake earth berm ? That should equal jail time for all those who "were in the know but made it their free choice to keep silent".

[@marcusbootle6410]

Very, very odd Juan. I am a 737 A+P, and there is no obvious reason as to why the gear couldn't have been lowered, Flaps/slats extended and brakes operated. Maybe you got it with smoke in the cockpit, fire handles and a large serving of panic? As for the Localiser antennae, if the horizontal alignment is not high enough, it should be raised above the ground level with a frangible structure. Great report Juan, waiting with interest for the formal report.

[@ibrahimarticov6978]

Out of curiosity, they said something about birdstrike. Is it possible for birds to jam or probably break the landing gear? Or perhaps the landing was hard that it broke the gear? I really wanna know more about planes in general.

[@bobroberts2371]

Could this be a CRM event like August 1997, Korean Air flight 801 ?

[@jlvandat69]

I'm guessing it must have been smoke in the cockpit or some other "cockpit crisis" that caused the crew to take such urgent action.....they behaved as if they were partially disabled. Not sure if a bird strike can cause windshield damage, but that was another thought. Very sad situation. I'm wondering how much weight and $$ it would cost for drogue chutes on commercial airplanes.

[@miltonsantiago6086]

​@ibrahimarticov6978 I am also an A&P mechanic with 10+ years experience on this specific type of aircraft, there's no bird big enough on this earth to cause catastrophic failure to that landing gear. As for a hard landing, I haven't seen any report anywhere that would suggest they ever even extended the landing gear, so this to me looks like a classic case of tunnel vision of these pilots.

[@emilycrewe3794]

We can only speculate, of course, but I do definitely wonder if their were fire indications (real, faulty, or perceived on the part of the crew) that lead to the crew’s decision to land asap, despite the lack of gear and flaps. I can’t imagine a scenario where any competent pilot would choose to perform a landing like this outside of a catastrophic emergency on board.

[@LBGUKRWP]

My gut is telling me given the compressed 7 minutes timeline the crew panicked and wanted on the ground asap and simply forgot the gear wasn’t down already

[@lcfflc3887]

I came across your channel after your forensic video picking apart security camera footage of my (bear with me) mother’s best friend’s husband who’s private aircraft vertically nosedived into the ground which took his life and his co-pilot’s in Oct 2022. I think it was a Cessna, one that crashed into a car dealership lot of cars in southern Ohio. It was an extremely tragic time for their family, their boys who are pilots themselves, and even more shocking for me knowing them, and for the grief of my mother and her friend. You helped me understand some of the circumstances around that morning he died, a time that left many of us with complete question marks about why or how what happened, did. Ever since, you’re my go-to guy for aviation forensics and what not. Very informative and educational knowledge that you share and it is always important. Thank you for your insights and all your efforts, Juan. They don’t go unnoticed.

[@DeltaDawg]

Tell me what part of this video has any forensic reporting? I can tell you one area… it’s where he mentioned the airplanes speed at the end of the runway and how many seconds it took to hit the concrete building after leaving runway, which he got that part wrong. His analogy is great and easy to understand, but there isn’t any forensics, that will take a lot of time to release the forensics

@@EddySpaghetty the person making this video is a pilot, he is not a accident reconstruction expert. For example…. I have not seen one person mention the landing gear sensor. The bird strike could have caused major electrical issues, including taking out the landing gear sensor…meaning the pilots may have thought the gear was down but it wasn’t….there are literally dozens of reasons why the landing gear won’t deploy, including manually….to assume the pilots just automatically forgot just doesn’t make sense to me, especially since they aborted the initial landing attempt. The guy making the video keeps mentioning 7 minutes….they didn’t have just 7 minutes, they could have taken more time if they chose to. We don’t know why they landed when they did, maybe the hydraulics were severely damaged, major electrical damage, including sensors, and on top of that there is a good chance that there was smoke entering the cabin and/or cockpit. There are multiple failures that can prevent the landing gear to be deployed manually as well…I’m just saying, people shouldn’t rush to judgement, defaming these hero’s. The guy making this video is a pilot, he shouldn’t be harassing this crew without all the facts, he knows zero about what causes flying

It’s okay to point out other factors from your view point. What isn’t okay is the barrage of abuse you continued with, trying to rubbish the career of somebody you don’t even know, who happens to have over 40 years of experience in aviation including flying a number of planes and jets in the Air Force including the giant C141 Starlifter, multiple vintage biplanes, multiple small wing aircraft, water tankers while working as a fire fighter pilot, sea-planes, survey planes and now a 25 year career flying 757s and 777s at American Airlines. He started flying when he was 15. I already know he’s got more pilot experience in his little finger than you have in its entirety by the way you talk. And while you’re entitled to make and voice your technical observations, you have absolutely no right to trash talk about someone you don’t know, who does a job you know nothing about.

Yep, every pilot I know thinks this. Surprisingly this is more common than people think, in a loud cockpit full of alarms…it’s easy to miss a “gear up” warning. Reminds me of the PIA crash in Pakistan few years ago, amazingly…everyone also died except 2 people in that crash too, just like this one

[@makuhenry]

Professional Pilot here, 3 decades at Airline level. Unless exonerated by further evidence, these pilots failed in their due diligence to handle the situation. A bird strike is not that serious, even if it costs you an engine. Slow down (your actions). Aviate/Navigate/Communicate. Declare the emergency, find a safe block of airspace, work the emergency, run through all applicable checklists, use longest runway, roll the emergency trucks, prep the cabin, run through every possibility to get that gear down (airliners do land with gear problems fairly often, not usually a fatality event if performed adequately) And by all means, you never land on the back half of a runway if you have any controlabilty remaining. This entire thing might be as simple as a botched go-around. One pilot retracted flaps/gear, didn't inform other pilot, they got distracted with the runway change, and didn't complete pre-landing checklist? If they actually thought they were handling an emergency, it would have been difficult to handle it worse. The reinforced burm is a terrible design oversight, and although it heavily amplified the severity of the accident , it was not the root cause. I really hope I'm wrong, but it sure looks like these pilots cost many innocent passengers their lives.

[@nicholasespinoza9610]

what if both engines were damaged like the miracle on the Hudson incident and smoke was filling the cabin?

[@peterclark8208]

Even with both engines failed with a return to the airport, once the landing is assured, you should will be able to drop the gear and select flaps…

[@kates5540]

Even if the other pilot retracted the gear and/or flaps, they should have got a GPWS warning and they didn't stall so they should have noticed how fast they were going. Seems like an extreme case of tunnel vision where they managed to tune out basically everything or they had multiple failures they were dealing with

As a 34 year aircraft mech I always appreciate your take on incidents. A 737NG can fly with zero hydraulics. It has control cables to all flight controls and flight control tabs will deflect if hydraulics is lost to allow manual reversion tab assisted flight. Also under normal conditions the 737NG can deploy the TR’s around 10 feet above the ground via radio altimeter. But I think it hit so hard it pulled this sleeve back a bit. I’m very interested to see what they find. It has been a bad week for aviation.

It did Fly. After hitting the birds during descent for the first landing I believe they aborted the landing so they could continue and try to lower the landing gear….it’s obvious the hydraulics stopped working, doesn’t mean the birds caused it, but they was not working for sure..:.I do believe the right engine failed not long after hitting the birds which is another reason they aborted the first attempt, and I believe engine 2 failed on the second attempt, why the landing. Here are other reasons…there are dozens of reasons the landing gear may have issues…. For example, a faulty sensor, meaning the pilots may actually think the landing gear was deployed but it really wasn’t…what about the actuators being faulty ? Many different reasons as to why the landing gear wasn’t deployed and it not be pilot error. Anyone who suggest it was pilot error at this point is just a ….well, I can’t say that here…

What is the max-airspeed that the gear will drop manually? I cound't find that in the QRH. I assume above a certain speed gravity alone wouldn't be enough to fight the aerodymanic effect on the gear-cowling?? (although they would have still dropped once it was on the ground) Additionally, is it possible they had an entire failure of the electrical systems, seeing as the transponder switched off at the time of the bird-strike... that would explain them not being aware that the gear hadn't dropped/locked, or pulling the manual-release.

25 year as airport engineer in Europe. When see this crash I thought got it down well but going fast and thought will be OK sliding off runway straight. But then the plane hit that concrete lump and made me feel sick and blood to boil what was that doing right at the end of the runway. It should never been there it killed them. Most if not all would of walked away if this airport was build and designed well. You have a soft run off area or an aircraft arrest area that work so well if only have a sort run off where the plane sinks down and slows safely. I'm so sorry to all that lost loved ones.

When I saw the video of the impact, I noticed all these things and it created way more questions than answers. This is looking like a case of panic and lack of slowing those hands down in the cockpit. The speed that they touched down at was insane.

[@elheber]

Could the pilots have misidentified the malfunctioning engine? It could explain the rushed landing and the reverse thruster on the wrong engine in the video. Though it doesn't completely explain the retracted landing gear and flaps. If the pilots had the wherewithal to engage reverse thrust, they'd presumably have thought of the landing gear too. The other idea rattling in my head is that the engine damage unlocked the reverse thruster vanes in that engine, which could have led to the rushed landing. But I don't know how that would even be possible.

[@OMGWTFLOLSMH]

Yeah, despite the birdstrike, I bet these pilots screwed up big time. Panic, lack of preparedness/training, distraction, etc. Like Juan said, 7 mins is not enough time to evaluate and go over a long and somewhat complex emergency checklist. I had no idea how easy it was to manually extend the landing gear, so there's no excuse for it not being lowered on this plane. That may have saved them all, with the potential for braking, steering and operational reverse thrusters. Not to mention, the extremely long and high speed touch-down. I think these two, forked up - big time. The airport is at fault for the deaths though, because IMO, they'd all have survived had that concrete berm not been there.

For all the potential mistakes here.. the fact remains, if that air craft didn't hit anything solid, it would have eventually rolled out to a stop in a cloud of dust and likely 90% or more onboard survive this accident. The biggest question has to be what happened that created SUCH a rush to get the aircraft on the ground so quickly? Everything else seems to be the result of trying to get the job done super super quick - the biggest question is - why the rush? the aircraft appeared flyable. The approach itself is remarkably stable and controlled. It wasn't visibly on fire.

I don't understand why they didn't have the landing gear down. The plane likely still had hydraulics but even if it didn't, the plane is equipped with a manual system to deploy the gear.

[@Swiggityswagger]

They had no flaps out either. Obviously there was no rational thinking going on in the cockpit. Looks very much like they panicked and just tried to put it on the ground as fast as humanly possible.

I think it can be said definitively that some hydraulics existed due to pitch control in the flare being evident. And as you say it is a mystery why the cables weren't pulled for manual gear extension. This is practiced in during ratings.

[@teebob21]

I understand perfectly. The pilots panicked, and that got nearly everyone killed.

[@kctoon5062]

They were at low altitude with possibly no power and a teardrop turn to make. Leaving the flaps and gear retracted extended the glide so they could turn around and get back to the runway. Gear couldn't be put down then, because there was no time to assure it was all locked in; and the APU hadn't been fired up to handle the flaps and spoilers.

[@kctoon5062]

@@Swiggityswagger The question is why did the pilot feel he had to put it on the ground as fast as possible. If he had a reason, then keeping the gear up and the flaps retracted was possibly a very good idea. A belly landing is do-able in an airliner (unless some idiot has placed a huge chunk of reinforced concrete in your non-optional path).

[@ChevyJay283]

Juan, I remember your analysis of the Oct '23 FedEx cargo Boeing 757 making a gear up landing at Chattanooga, Tennessee (KCHA). Nonetheless, it appeared that that crew took the time to run the checklists and performed a 'belly' landing resulting in no injuries and minimal damage to the aircraft. While very rare that one has a wheels up landing in an airliner, that incident showed that it is a survivable event even with a 7,400 ft runway. The runway at Muan (RKJB) is almost 9,200 ft. There are a number of airports in the US that are equipped with Engineered Material Arresting System (EMAS), not sure if this is used around the world and not sure that it would be helpful without landing gear.

Juan, Very informative update on this tragic accident. I’m a former GA pilot (my health keeps me from flying now) but I am an avid simulation pilot. I recreated this fight with the PMDG 737-800. An aircraft that I fly most of the time in MSFS. I recreated the compressor stall via bird strike by cutting the engine off… BUT I also used the fire suppression system on the number two engine immediately after the simulated bird strike. I made the aircraft VERY difficult to handle and made the flaps extremely sluggish. The landing gear was fully functional as were the flight controls. As per the ADSB data all this was performed prior to the go around from RW 01 to RW 19.. the aircraft also sped up pretty quickly. Also the 737 Should have been screaming and the flight crew if they were flying at 144 KTS without gear down prior to bird strike. I hope this helps and please continue your great work!

Most of the passengers didn't really know what happened. That was a plus. The only one that was frightened was the passenger who was sitting behind me. This was his first flight. After we landed he told me he was taking the train even though the airline gave free round trip domestic tickets.

Similarly, at Chicago Midway International, within 400ft of the end of the sealed runway surface you would overrun through an 8-lane road intersection, carparks, residential houses, restaurants and so on, depending on which runway you overrun.

​@@matthewjones255An airplane did overrun, went through the fence, hit a car, and killed someone. I think Midway has that special arresting material now on the ground.

We rarely operate to 9 in san diego

[@kevinhanna9440]

As Bobbie already said, San Diego is basically a one way airport. If you overrun RW 09 into that intersection, you are then going uphill into downtown SD. Thanks JB once again. Also as others have said. Just wait for JB.

at SAN when the ceiling goes below 700ft runway 9 is required for landing which has been almost every late night & early morning this month

I listened to South Korean officials meeting the press. The Press asked why there were no fire trucks ready. Officials answered that the the pilot had sent "Mayday, Mayday, Mayday" after the bird-collision but never asked specifically for fire trucks.

Thank you Juan for the timely, professional info wrt the Jeju accident. I've been retired for almost 4 years, but I often sift through accident reports to see what happened and what the crew did to rectify their situation. I usually end up shaking my head.

Thanks for your commentary on this tragedy. I hope that more conclusive information is forthcoming soon. RIP to the souls who died.
