H225 down in Korea
 
It would appear that an Airbus H225 has crashed into the ocean.

Fuselage found and one body recovered so far.

Sad news and tragic for the families of those involved.

I think Airbus may have some difficult questions to answer - again.

Police officers were watching the chopper after takeoff because it began to fly unsteadily at a low altitude and in a skewed direction. They said the helicopter crashed after flying about 200 meters
I know we love to theorise, take off with no stab engaged? What is the handling like on the 225 in that case?

Pretty wobbly, just like any other helicopter (without a stabiliser bar). But with the 225 you engage the autopilot after start and leave it engaged until you are going to shut down. Or at least that’s what you should do!

You´re right - but depending on experience, finger trouble, not only disconnecting the upper modes - but all of the stabilization, is a possible scenario?

Jimmy. 2nd Nov 2019 13:39

A "finger fault" disconnecting the SAS is easy to imagine, but a SAR crew crashing an aircraft after take off at VMC and no turbulence is very, very surprising...

malabo 2nd Nov 2019 16:38

Midnight after the sliver moon had already set, shoreline helipad into the inky black. Nothing VMC about it. Should have been routine for a SAR crew, so something went sideways.

SplineDrive 2nd Nov 2019 16:49

They found the fuselage and are attempting to recover the crew/passengers... any news if the rotor and top case landed with the rest of the aircraft?

You are correct. I have misread the takeoff hour. Happens sometimes when reading at commuting...

Looking at the circumstances I would bet so. Takeoff from a lighted helipad into the pitch black night over sea. End of flight just 2 minutes after takeoff.
Even with all the gizmos on board Occam's Razor would give a clear direction where this will be going. Whatever the detailed circumstances will have been.

"Seven passengers were aboard: one person with a cut finger, five rescue officers and a friend of the injured person."

I'm gobsmacked. A night SAR deployment for somebody with a cut finger. Surely not.

The first article said a severed thumb, but still in no way justifying a night MEDEVAC!

Not sure, but I doubt there is any differentiation between day and night for a flight like that, usually only weather. They should be well prepared to fly in the dark. Also, there are certain protocols that are followed by first responders called "quality of life". Nobody is going to die from a severed thumb, etc, but if a timely flight is the only way reattaching an appendage is possible, air is called. I don't make the rules.

Disagree! The outcome of a replantation is the earlier the better the patient is in an approbiate traumacenter. A thumb is not a part of your body you could easily renounce for manual work force, especially if you are of younger age.

It doesn't surprise me. In my (pre-NVG) SAR days I was called to more than a few highly exaggerated, allegedly "life or death" cases. One involved going single pilot to a wire infested, unlit site in the hills on a moonless night to rescue a drunk who turned out to have a relatively minor cut on his hand, self induced on a broken beer bottle. Another involved a jungle landing to a soldier with an alleged broken spine. Having risked the aircraft and crew, the patient walked out normally with the rest of his platoon and climbed on the aircraft unaided. A third involved rescuing a "very seriously ill" sailor some 85 miles offshore from a fishing boat. On reaching him, he was stiff as a board and had obviously died the day before. We were probably called to avoid the boat having to dock or continue trying to fish with a cadaver on board, the latter being considered a bad omen.

Ah, memory lane. "And here I was..."

Shy, just because you're paranoid doesn't mean they're not out to get you. :E

Time critical, life changing, though not life threatening. I'd expect this to be a GO for a specialist SAR aircraft.

The main rotor is there...

rrekn 4th Nov 2019 08:48

And in the right place... From the damage to the blades they were still rotating fast on impact.

ShyTorque 4th Nov 2019 10:18

But what about the tail rotor? That sad sight suffered one hell of an impact, nose first by the looks of it.
No tail boom. Before or during impact sequence?

It looks like it but I'm not convinced, as the bulk of the fuselage look relative uncompromised, so I suspect damage in the recovery. Having seen a few aircraft in the AAIB hangar that had high speed impacts with the water, I don't think you could do so in such a way as to destroy the cockpit section, but leave the rest looking like that. Just my thoughts


ShyTorque 4th Nov 2019 10:49

It looks like what (not clear what you mean)?

It looks like the MR blades were still being driven at impact

212man 4th Nov 2019 12:21

My comments were about this statement:

ShyTorque 4th Nov 2019 13:10

Thanks, understood. It would be disappointing if recovery caused such catastrophic damage.

Looking even closer at that depressing image it looks like the cockpit might have hit the water travelling from right to left and the impact forces completely detached it. Unless I'm mistaking a paint colour change, there also appears to be fire damage to the rear of the fuselage; obviously it wouldn't have burned underwater....

Or met the rotor coming the other way.

Looking at the damage (Cockpit section longitudinally crushed) this thing went in straight and fast with solid engine power turning the rotor at impact. Not spinning. And with enormous RoD.
Taking this together with the circumstances of visibility at the time of the crash, I don't expect much of a surprise...

If we look at the break line of the cockpit section I would say we can pretty much rule this out. Even ignoring that we are not talking about a teetering rotor the typical Robby cut line looks totally different. Or that of the CH53 of the German Army that chopped off the top of the cockpit section a couple of years ago after a faulty maintenance for that matter.

so why no crush damage and deformation aft of the cockpit?

Concentric 4th Nov 2019 19:36

Some pictorial info on the location in this link. I presume it lifted from the helideck on top of the rock. It didn't get very far.

I tend to think medevac flights are overused, but from a small island with perhaps no medical facilities beyond a first-aid kit? If it were my thumb that got detached, I'm pretty sure I'd be quite happy to jump at a chance to get my thumb reattached while it was still possible.

jolihokistix 6th Nov 2019 02:51

The patient was said to be a fisherman, so a working thumb might be a useful thing to have.
Now reporting that a third body has been located, perhaps, it is said, the same one that they dropped when lifting the fuselage.

malabo 6th Nov 2019 05:44

The 139 Bahamas, 505 crash Kenya, I don't get the resigned "no surprise" connection, as if any night takeoff without a visible horizon is doomed. 30 years of offshore and medevac and the thousands of pilots I flew with handled it routine and safe. The EC225 is a very capable aircraft for that role and situation, probably the best. And flown by a SAR crew, which in my experience is better qualified, trained and experienced for those types of missions than anyone else, including offshore pilots. Good crews can make mistakes too, witness the Irish S92 SAR crew even with the FLIR operator gently tapping them on the back. And sorry to disappoint all the EC225 bashers that the tranny and head were still intact, maybe it's time to get over all that and move on. The 92 guys did.

If you look at the construction of the Puma you will find a significant difference in solidity of the 'greenhouse' front office to the rest of the fuselage.

megan 7th Nov 2019 00:30

Not the case, you draw the wrong conclusion, merely pointing out the similarity of circumstances. Done my share of night rig take offs.

Outwest 7th Nov 2019 21:06

Video posted in post #34 says there was video of the crash? At 1:23 is that the heli-pad on top of that island? By the comments about the tail being 90 m away from the fuselage and 2 bodies found near the tail would that suggest that the tail was chopped off in flight? Violent control inputs?
