HP-2010DAE (mfr 1999, ex-FAT/EVA Air) is off the runway at SJO after a hydraulics malfunction; I was hesitant to call this a crash, but considering the airframe is in pieces, I guess that's an accurate description.

Aircraft allegedly returned to the airport with a hydraulic issue and went off the runway and broke into 2 on the return. Video of the aircraft linked below.

It crashed at SJO, not SJU.

It crashed at SJO San Jose, Costa Rica. Operated by DHL AeroExpreso based out of PTY.

I don't think that's going to be repaired somehow.

Typo has been fixed, thanks for reporting it.

Dumb question - but to cargo aircraft have escape slides on the L1 door, or to they just use a rope for the crew to evacuate?

Nothing some speed tape can't fix.

That'll buff right out !

Don't know the answer to that, but they were actually taken off the aircraft by firefighters using ladders. Just saw a video a few minutes ago of them coming out.

It's incredible how many accidents/incidents are caught on camera these days. Even a 737 suddenly nose diving in the middle of China just happens to be caught on at least two cameras.

Interesting, I wonder why it made that right turn into the ditch or if the hydraulic issue also effected the nose gear in some way, or if that was turned the entire time and it finally got traction which is what caused the turn. Too bad, that plane was so close to being stopped on the pavement. Glad the crew is fine.

Such a shame the aircraft ended up crashing at the very end. But, it definitely looked like the crew would have escaped with little to minor injury and you can't put a price on that.

Everyone I've seen has escape slides to accommodate any supernumeraries that might be traveling along with the cargo but are not really crewmembers, since the ropes or reels require training. There are a lot of different variants though with multiple conversions per type and new builds on top of that. So it is possible there is something out there that deletes the escape slide at the L1 door.

I think one could safely go with "accident" since that has a specific meaning in civil aviation and this event would be accurately described that way.

In various videos you can see that the brakes start smoking before it starts sliding sideways. It kinda looks like the right brakes locked up.

Not sure about DHL AeroExpreso, but UPS' 757/767 fleet does not have slides, just escape ropes and reels.

Sad, another gone from the air to soon.

Crew members had announced hydraulic problems before landing at SJO.
Fire equipments were ready as well.

I'm certainly no expert, but the aircraft seemed to largely be doing alright on that runway until the smoke appeared from the main gear. With hydraulic failures, steering capability can be affected, so I wonder if there was asymmetrical drag/friction as a result of one set of tires blowing or locking up. It is important to point out there were significant left rudder inputs before the gear smoke.

To add to that, the thrust reverser on engine no 2 seems to be deployed whereas the one on engine no 1 isn't. This might have contributed to the right turn.

Edit: As can be seen here:

Finally something I get to chime in on as an automotive engineer! It looks like only the left main landing gear is smoking which could introduce two separate possibilities(assuming there isn’t a rightward steer input from the captain but I personally can’t tell from the video).

1) Left MLG locked up for some reason and the resulting difference in yaw moment between the left and right MLG caused the rotation. I personally have my doubt about this one because, I have a hard time believing it would cause this much rotation. In my experience locking up on dry ground should at least provide you with 40-50% braking power on that wheel. Granted most of my tire modeling experience is with small race car tires and there are bound to be difference between those and aviation tires. So I could be wrong there.

2) Hydraulic failure of the brakes on the LMG. This would obviously depend on having separate systems (or at least an automated circuit isolation mechanism) to maintain hydraulic pressure on the right side. The smoke in this case would be hydraulic fluid burning on the brakes

it looked like the mlg doors were open? glad to hear the crew is ok.

From local press releases as I live very close to San Jose, Costa Rica downtown.
The 757 took off from SJO at 09.36 local time bound for Guatemala City.
Translation from the cabin desk when climbing at 21 000 feet above sea level: "Mayday, mayday, mayday. We've got issues in the left hydraulic system. We're two souls on board. We actually have 2.30' of jet-fuel."
Thus, the emergency was declared. The plane returned and touched down at 10.26 local time at SJO runway 07.

Nose gear doors too. Typical to see in a hyd sys failure. I agree, glad the crew's ok.

Well, makes unloading the cargo easier with the new rear cargo door.

It’s been many years but IIRC with loss of fluid in the left hyd system you lose nose wheel steering, this requires use of differential braking to maintain directional control. This could explain why they lit up the brakes when things got sideways.

Sad that a 757 just left our skies.

Anyway, sorry if it seems like a dumb question, but in video that an above user mentioned, I don't see thrust reversers deployed? The pilots claimed that they had failure in the left hydraulic system, which impaired the braking. But wouldn't they have been able to deploy thrust reversers? Even if they only deployed the right thrust reverser, could they have done it slowly and gradually so the asymmetric thrust isn't as much of a problem? Would they not have overran if they did that? Sorry if it seems dumb but I was just wondering.

On the 757 is you lose the left Hydraulic system you have to land F20. Some spoiler panels are inoperative, left thrust reverser is inoperative, nosewheel steering is inoperative. Use of differential braking is allowed and at the airport elevation and max gross weight they would have needed around 5,500’ of available runway. It should not have wound up doing a ground loop. Perhaps they had additional failures that are not know at this time.

Didn't an Air Jamaica 752 the same age as this one crash land like this after a hydraulic failure in 2018?

We'll dub this, "the Etihad Ouchie"

Yikes!

SJO is opened again. No more than six hours after the accident.
However, many flights were previously canceled for the known reason.

Maybe they'll take one of AA 's 2001-02 builds who hasn't found a home as a replacement?

Maybe some blown tires also contributed to the right swing? The crew clearly tried everything to save it. I'm glad the crew is safe! Planes can be fixed or replaced. Sad, looks like she might be a write-off.

Swing tail.

Looking at the pictures, did that thing even land on the runway? Something doesn’t look quite right…

It was that or crash through the fence onto a busy highway they had no choice SJO isn’t that long a runway.

I'm assuming you didn't watch any of the videos.

How’d it wind up between what appears to be the vehicle service road and the taxiway?

It did, it just spun out at the end.

I know there’s some elevation, but it’s a 3,000 meter runway (or, in other words, a mile more runway than some places that regularly see or have seen 757 service).

This is why the ground next to a runway should be level with the runway wherever it is practical. If there hadn't been the depression/ditch between the runway and the road, this aircraft would most likely still be intact.

How would you expect it to go if brakes on one side locked? Would locked wheels or wheels with properly operating brakes have more traction?

Locked wheels have less traction, properly working brakes and rotating wheels have more traction. ABS in cars is based on this principle: it reduces brake pressure on a single wheel if that wheel is locking up (rotates less than other wheels).

Further to the discussion above about there being an evacuation slide or no slide, where is the *door*? Door 1L is an outward opening door, and the photos show just a gaping hole for the door opening.

The aircraft is quite far off the runway. There is the runway and taxiway, then grass, then a service road and then a drain at the other side of the service road. It broke up when it crossed the service road and then hit the drain. The pavement you see at the right of the image is not the runway, but a taxi way which is at a 45 degree angle off the runway.
