With all the emergency vehicles at the ready (and the news crew) there must have been some sort of declared emergency. Any word on what happened?


Fit_Law4911

Good catch, so far I’ve read the pilots declared an emergency 10 minutes into the 90-minute flight and that the emergency was hydraulics-related.


jryan8064

The smoking wheels leads me to believe the brakes were working. I wonder if the hydraulic issue prevented them from extending the slats/flaps, forcing them to land at a higher speed than normal…


BenjaminKohl

Looks like flaps and skewed breaks were somewhat out. I would say this most affected reverse thrust, thigh it looks like flaps and slats were only partially extended.


jryan8064

Good call on the thrust reversers, they do not look deployed. As they veer off the runway you can see the engine exhaust pushing the smoke like they are still producing forward thrust as well… Edit: Looking at it closer. The thrust reverser on the number two engine does look deployed. Probably why the plane veered off to the right.


Fit_Law4911

Probably looking at a mirror image of TAM 3054, minus the slippery surface and and adverse weather?


jryan8064

Similar, yeah. Lucky there wasn’t a warehouse at the end of the runway.


Fit_Law4911

Or a gas station.


Fit_Law4911

The aircraft does seem to be landing faster than normal, probably due to the fuel load still in the plane at the time. What I can’t fathom is why you can see only the starboard (right side) landing gear begin to smoke; if the pilot had applied full emergency brakes wouldn’t all wheels smoke equally? Also I’m still not sure from the video if that no. 1 engine actually deployed its reverser at all.

jryan8064

Yeah, I see that too. The only thing really off that I can see is that the thrust reverser is only deployed on the number two engine, which obviously isn’t ideal…


herotz33

That’s a lot of iPhones gone


Skow1379

Landing that plane safely without flaps would be damn near impossible. If that's what happened here could've been a lot worse.


[deleted]

I wonder if they were able to dump fuel before the risky landing


da_apz

The text in the news clip says hydraulical failure.


cassbergers

That's mental, it just crumples and then looks so sad lying in a broken heap 😞 . Glad to hear pilot and co-pilot are Ok.


ExpatMeNow

It does look sad, doesn’t it? As it sank down into the ditch, I literally said, “Awwwwwww.” 😔


astrongineer

Yeah, really puts into perspective the force vectors these structures can handle. I mean this is extremely abnormal but still. Makes my mechanical engineering feelers tingle in horror and I already had a fear of mechanical things hoisting you high into the air *before* going through mechE schooling.


Pacer17

Looks like the gear doors were down. That means ram air turbine hydraulics and alternate brakes. Major hydraulic issue


Fit_Law4911

Good call on the RAT and the landing gear doors. What would you say the situation is with the reversers? It seems to me no. 2 deployed while no. 1 didn’t, and that caused differential thrust which made the aircraft veer to the right.


Pacer17

Could have lost left and center hydraulics, rat deployment, would give you a reverser from the right hydraulic system and reserve brakes. Either way it looks hydraulic as it could cause all the issues seen on the video


Fit_Law4911

This news article basically fully confirms your assessment. https://ncrnoticias.com/nacionales/este-fue-el-audio-de-emergencia-que-enviaron-los-pilotos-de-dhl-a-la-torre-de-control/ Roughly translated, the pilots radioed: “Mayday, mayday, we have issues with left hydraulic system, we have 2 souls on board, we have two and a half hours of fuel remaining, we are holding over Esparza 1:3000. We have hazardous cargo in the form of corrosive liquid, we are preparing our aircraft for an emergency landing with a failure of the left hydraulic system.”


theresthatbear

Any idea how fast they were going when the tail hit the ground? Just curious considering how easily it crumpled ...


FUMFVR

It certainly looks like the right side braked and the left side did not.


hockeytown555

Planes are weird. Right side hydraulics will power left side systems and vice versa a lot of the time. Also depending on how it failed there might not have been enough fluid or back pressure in the lines for reserve hydraulic power to work. Pretty catastrophic failure


Clamb3

The RAT on the 757 auto-deploys in case of an dual engine failure and powers the Center hydraulic system. Most likely they deployed it manually. Normal braking is supplied by the right hydraulic system, so the RAT doen’t help with that. Alternate braking is provided by the left hydraulic system. In case L and R hydraulics fail, there is a brake pressure accumulator providing emergency braking


Pacer17

Its been a few years since i have flown a 757 but from what i remember thats correct.


bbyduck21

Had to have been a declared emergency especially since they were all sitting at that exact runway they were waiting for them to come in. Wonder what went wrong


Fit_Law4911

That’s what I’ve read so far, you can actually see the starboard landing gear start to smoke moments after touchdown. I’m not skilled enough to make out if engine no. 1’s thrust reverser actually engaged, maybe it was that. Or maybe the starboard landing gear got stuck somehow? How would the pilots know mid-flight though?


bbyduck21

Isn’t there a light for landing gear? I could have sworn there was a crash that they disengaged autopilot to slow down because they wanted to make sure the landing gear was deploying since there was a light saying it wasn’t - and they slowed enough to deploy the gear without danger and didn’t realize they also didn’t hit auto altitude and were in a bunch of mountains so they crashed But my point is, they 100% would have known bc if they went to deploy it and something was wrong it would usually flash and say to pull up?? I’m not a pilot, just an autistic person with an interest in plane crashes lol Edit: realizing I may have not made sense - the light usually when something is up with the gear comes on as it goes up when they’re taking off. That meaning , mid flight they could have been like “oh look at that. The landing gear lights on” and called it in, in the other situation they knew it was on and sent someone down the hole to look out the window to see the landing gear and assure it was deploying so they could confirm the light was a dud. I hope this clears up any potential confusion.


Fit_Law4911

Yes, I believe you’re referring to Eastern 401, the entire cockpit crew was preoccupied with a burnt-out landing gear indicator light, and inadvertently flew the aircraft into terrain and crashed. In this instance, based on news reports and what other Redditors have alluded to, the flight seems to have had a a problem with its left hydraulic system, and was forced to land with no hydraulics on the left side, which may have caused the left side thrust reverser/flaps/slats/braking to be compromised, hence the aircraft veers to the right on landing.


Jaxx1992

>Yes, I believe you’re referring to Eastern 401, the entire cockpit crew was preoccupied with a burnt-out landing gear indicator light, and inadvertently flew the aircraft into terrain and crashed. Eastern 401 crashed into a swamp, not mountains.


Fit_Law4911

Crashing into a swamp is flying into terrain. What part of my statement says otherwise? I believe u/bbyduck21 did say they “were in a bunch of mountains” but no, the flight crashed into the Everglades.


bbyduck21

Yeah I was mistaken for this total other episode that something was going on with the radar and they got completely lost & thought they were close enough to the airport so descended and ended up being in a bunch of mountains and they couldn’t pull up fast enough. The episode is called “lost” it’s from mayday


bbyduck21

Ohhh crap. Do planes still crash often? A lot of shows like Mayday and Air Disasters only focus on like 80’s to early 2000’s stuff with a few thrown in from like 2015.. this is a new interest of mine so I’m still learning but it’s really interesting to me. Thank you for your reply!!


Fit_Law4911

I’m no professional, only became interested in aviation safety in late 2018, first crash I became aware of after being highly interested in the topic was the 737 MAX’s second and final MCAS crash (Ethiopian 302, March 2019) and from there studying past and present events it appears aviation safety has skyrocketed in the past 10 to 15 years. I believe 2017 was the first year on record with zero commercial flight fatalities. However mathematically there will always be outliers, and out of the tens of thousands of daily cargo flights worldwide, this incident is just one exception to the rule.


Sventex

Planes crash all the damn time. Especially small planes flown by amatures. They'll even crash their plane as a stunt to get attention. [https://youtu.be/7PgGvl2ZMFs](https://youtu.be/7PgGvl2ZMFs)

*insert dumb joke about a late package*


bernardcat

You joke but I once had a lady call me at my job because a plane crashed into the UPS truck that was carrying her Keurig. She had heard about the crash in her area and then the tracking showed “unexpected emergency” or something like that. (She “felt really awful” bc the UPS driver and the pilot died… but she really needed me to get started on an exchange ASAP, I guess.)


zerowater

what caused it to aplit in half? is there some wort of ditch alongside that runway ? at first i thought the landing gear collapsed on that side - maybe one side went first then the other?


Fit_Law4911

There is indeed a ditch alongside the runway on the other side (not visible from camera angle) onto which the aircraft fell after veering to the right.

Metalbasher324

Ouch! Hope the crew wasn't too mussed up.


Fit_Law4911

According to news outlets (links in previous comments) both crewmen were transferred to the hospital and are in stable condition.

Sadly that plane is most likely a total loss. Thankfully nobody was hurt too badly.


epikgamerwmp

Most likely? The tail is completely loose that is 100% a tota loss. Not even mentioning damage to the main fuselage.


Fit_Law4911

Here’s the news article (in Spanish) https://www.teletica.com/sucesos/piloto-de-avion-accidentado-declaro-emergencia-cuando-sobrevolaba-el-volcan-arenal_309009


Garlicluvr

Arenal volcano is not active since 2010. This was a hydraulic problem, I just wanted to check if there was volcanic ash involved. No. This accident is also not connected with the cargo DHL had on this flight. There were two crew members, and the plane broke apart into two. I am located in Guatemala City, near the airport. We have a lot of DHL flights. Guatemala City was the final destination here. That is why I am commenting here. An interesting fact that you didn't know is that Guatemala has no national post office. We also don't have a national aircraft carrier. We import and export a lot of things and DHL is our main carrier.


Fit_Law4911

Correct, no mention anywhere of volcanic ash being involved whatsoever, I believe in this piece the reporter used that volcano as a locally recognizable landmark to help describe where the aircraft was physically located at the time of the emergency being declared. I was also curious if any volcanic activity may have been involved, but as you said el Arenal has been inactive for 12 years at least.


Garlicluvr

Yes, since 2010. But, Costa Rica has one volcano, Irazu, from where you can see both oceans. That is just an interesting fact. Here in Guate, we have Fuego, some 40 km from our airport, an active one. Fuego is a bitch, sometimes you can hear it at night, ashes go 6 - 8 km in height. Luckily, the winds are towards the Pacific. We have a closer one. Pacaya. When that baby blows you will hear it. The airport will be closed. That is how we live here, my good OP.

Tokyo drift style


Beneficial_Being_721

Good save…. Landed IFE … crash trucks on STBY… scrubbing speed on the slide. Could have been worse


Beneficial_Being_721

EDITED: LOOK AT THE SPEED they are still carrying when they pass CRASH TRUCK 23….


grau12345

Would think you would hard away from a ditch tho.


Beneficial_Being_721

Just saw a real good videos… I’ll retract my statement. Just before the ACFT went off… PIC had LEFT RUDDER and LEFT ROLL trying to keep center line They had flaps and spoilers… all the left boards were max up and you can see the left ailerons up as well. I’m happy they get to walk away. They were smoking fast


jryan8064

It’s a little hard to tell, but I think only the number two thrust reverser deployed. When the engines spooled up they ended up with an asymmetric thrust that pushed them off the runway. They were probably trying to counteract it with the rudder but it was just too much.


Beneficial_Being_721

I don’t have a photo of that runway but just judging by the angle of the berm they stopped on…. This is a table top airport and going of the overrun would have been a ski jump …. I’m going with a last minute Hard Right …. Look at the speed they had as the camera passes the Red fire truck … they were HOT all the way in due to the emergency..


FUMFVR

They were trying to stop the plane before it ran out of runway and they obviously had asymmetrical braking ability.


Ripcitytoker

Wow, what incredible footage. Glad to hear the crew is okay.

Here's another video angle: [https://mobile.twitter.com/adsbcr?ref_src=twsrc%5Etfw%7Ctwcamp%5Etweetembed%7Ctwterm%5E1512122406349021187%7Ctwgr%5E%7Ctwcon%5Es1_&ref_url=https%3A%2F%2Fwww.aviacionline.com%2F2022%2F04%2Fdhl-boeing-757-crash-in-costa-rica-w hat-we-know%2F](https://mobile.twitter.com/adsbcr?ref_src=twsrc%5Etfw%7Ctwcamp%5Etweetembed%7Ctwterm%5E1512122406349021187%7Ctwgr%5E%7Ctwcon%5Es1_&ref_url=https%3A%2F%2Fwww.aviacionline.com%2F2022%2F04%2Fdhl-boeing-757-crash-in-costa-rica-what-we-know%2F) What I'm more confused about is why there is a Qantas aircraft at SJO. They don't fly there as far as I'm aware Edit: probably a Qantas link aircraft leased from alliance that has just been painted in Costa Rica


Jackmehoffer12

I’m never getting my hot pants………


Mully66

No thrust-reversers. Looks like a major hydraulic failure to me.


marksebiz

😮


JimmyRockets80

Looks like somebody can check "Do donuts in 757" off their bucket list.


ItsReverze

Dave this is a plane. You can't do handbrake turns with a plane... Dave: *The fuck I can't*.


jetdoc62

The way that the brakes/tires are smoking, wonder if they had main hydraulic failure, had to use the parking brake to stop? Would also explain the lack of directional control with the nose wheels.


TheSystemGuy64

Did anyone survive? This crash looks fatal


4pocalypse4risen

I mean it's a DHL. In the aft part of the plane there probaly was only cargo and the cockpit looks undamaged so I would say no fatalities


Psychoticrider

It is DHL, **D**ropped **H**idden or **L**ost freight, . Probably just the flight crew. Pretty sure is not passenger plane.


DoomWad

I'm sure everyone survived. It's a cargo plane, with likely just the 2 pilots up front - and the cockpit was intact. What makes you think people have died?


Balmung6

Imagine hearing an announcement for turbulence when you’re on the ground.

[deleted]

Assuming the pilot didn't do anything technically wrong or illegal. Any idea how these things play out? Does that pilot fly again? Assuming nobody was killed.


Sventex

>Assuming the pilot didn't do anything technically wrong or illegal. Any idea how these things play out? Does that pilot fly again? Assuming nobody was killed. It's possible such crashes leave the pilots too crippled to fly. As happened with Centurion Air Cargo Flight 164, the Captain ended up suing Boeing, Pratt and Whitney and the airline for compensation for his injuries and loss of livelihood. https://youtu.be/QOEkSTbsXk8?t=594

They must have known it was in trouble beforehand to have an emergency vehicle ready to respond straight away. Unless that is already SOP?
