Kedarnath 119 (Kestrel) spins off pad

Press calls it an emergency landing enroute due to a technical malfunction of the tailrotor. It definitely malfunctioned after the spinning tail hit the ground but up to then I think it was a perfectly serviceable helicopter. Hefty load on board, the usual high hover and running out of left pedal, maybe some rotor droop thrown in there that also takes away T/R effectiveness. Kedarnath is at almost 12,000'.

Can't post the YouTube link but there's a few videos from different angles.

See if this link works:


What options are left for a pilot once they get themselves in that situation?

How about gentle cyclic push forward, it the direction of the down slope,
after a 180 out of your command it should have been the natural reflex.
you get your ETL back, you get the tail in the wind, every thing is happy again, its like magic!

My instructor used to say, if does not feel right abort landing, you still have a perfectly flying aircraft.

Also avoids all the people milling around the landing pad that are slow to move away even once the helicopter starts spinning!

I liked the captions: "shortly after takeoff a technical issue arose in the rear motor... authorities have initiated further investigations to determine the exact cause of the technical snag". The finding might be: "the rear motor was missing from the helicopter"!

Anyway, good it ended OK for those on board.

I don't know why we was coming from above, this type of pedestal pad calls for an aproach from bellow, am I wrong?

to repeat myself the attraction to land at all cost is tricking your brain.
  • You have the aproach all scripted out on its last step
  • You have ATC clearance (sometime hard to get)
  • You have people watching you (like in this case)
  • You have people on board expecting arrival
  • You have your reputation of a good pilot doing the job
  • you have only one thing in your sight the pad
Despite all that, push the radio button, say "going arround" at the first sign of trouble.
that works for me, saved an old H269 airframe doing something stupid long ago with that method.

This view shows the whole sequence without losing sight of the helicopter

6 P's were missing? Proper Planning Prevents P!ss Poor Performance.

At least it could still hover OGE - just the TR wasn't up to it. Probably would have stopped turning if he didn't try to hover OGE.

More good training material.

Just don't plan on coming to the hover OGE.

Either aim for an IGE hover or zero speed landing to avoid running out of TR authority.

Forward and down all the way to the ground - as in helipad and not the scenery.

Wonder what his performance calcs looked like for 12,000'

I would have preferred spinning on the flat smooth concrete than the rocks

Don't forget the tail wind...
This was 99% a driver's foul up.

I looked the other day and it was 13 C there, so about ISA +22C!

Not sure that is OGE seems to come to the hover about 10 ft with is hardly OGE ? Could have got lower but not sure that would have helped that much. I assume a 119 has the throttle in the roof so cant roll it off a la twistgrip one ?

These pilgrimage shuttle flights are…interesting. It’s more akin to Christmas tree harvesting. Total flight time takeoff to landing is about 45 seconds. Time on ground…30 seconds. Passengers don’t wear seatbelts because it takes too long to get them strapped in and unstrapped. (There was a 407 that tumbled down the same mountain two years ago. Every passenger was ejected. All fatal.)

They're basically a ski lift.

Interesting analogy. Anyone unfamiliar with the latter, see videos such this one that had been shared on Rotorheads some time back:

Big difference in height and weight of load ! Having done tree work you are probably lifting less than a half of the machines capability !

Throttle on the collective, but should be irrelevant if the pilot would not stop short of the pad in a high hover at 14,5K D.alt.....!! OGE AUW on the 119 is just a little over 7K ISA, and here it seems to have been ISA +20.....

But it was probably something wong with the ''rear motor''......

Good grief!
So many people on the pad.
Watching the other video on the thread and a lot of other helicopter stuff.
Does nobody do hover checks anymore?
A lot of folks seem to just jerk the helicopter off the ground then immediately stomp on a pedal while stuffing the cyclic forward.

He was landing, not departing

To paraphrase John Lennon: "I'm just sitting here watching the world go 'round and 'round..." Slowly at first. Of course, the hapless pilot will swear...SWEAR that he had full left pedal stuffed in. "Nothing I could do, boss! That rear motor was INOP!" Sadly, we can see that he (she?) is frozen on the controls...just along for the ride...just like his passengers as it all goes wrong. Tellingly, he or she is even slow to cut the power once the thing has smashed the tail rotor to a bazillion pieces and the ship has landed ignominiously in the dirt (or "the scenery" as Crab hilariously says. I know we shouldn't criticize a fellow piloto, but jeez guys, we've got to be better that this! This accident did not have to happen.
