EH101 emergency landing
Local news "Viborg Folkeblad", near Karup Air Base (EKKA), reports that a danish Merlin EH101 Wednesday made an precautionary terrain landing. A military spokesman says that all danish EH101 are grounded, except lifesaving flights.
Sources within the military reports that all three engines stopped within few seconds and subsequent autorotation performed to an open field. Karup-helikoptere sat ud af spillet - Viborg | viborg-folkeblad.dk |
Calling AR after triple engine failure a precautionary landing...?
|
Is this a first in helicopter aviation? A triple engine failure.
|
Are the British ones grounded too?
|
Or a double pilot failure
Or a single fuel failure |

That's one of the issues, that military gives one explanation to the press, but fact is probably different...

remember this is a RUMOUR network!
so we are probably not getting anything like the full story. No doubt FH are on top of it, the appropriate specialists (none of whom are on this forum) will have the full picture
UK are still flying and I don't believe that any other EH101/AW101 are grounded so this suggests not a fleetwide/design problem At some point all will be made clear I am sure anyway congrats to the pilot for getting safely down DM |
Well.... the excellent Flt Lt Ben Wallis (for it was he, in charge) has finally, 31 months later, been handed his well-deserved Air Force Cross by a fellow helo pilot, the Duke of Cambridge, aka Prince William.
https://www.forces.net/services/raf/...c034-440992797 But, Flt Lt Ben's undoubted courage and expertise aside, what bothers me is how a three-engined helo can suddenly run out of power. To say nothing of the fact that it was at night, and over forest. Anyone care to say what actually went wrong - or, better still, point me towards the Service Inquiry? airsound |

Danish Merlins were originally RAF owned, there perhaps is the reason why.

Totti,
Think it was the other way round. We bought 6 Merlins of the Danes in an attempt to respond to the "lack of helicopters" criticism in Afghanistan. We bought the Danes 6 replacement aircraft. Airsound, The Merlin is an underpowered / undertransmissioned beast - a circa 11000kg empty aircraft with a max TOW of just 15600kg. At high weights and low airspeed it can be poorly placed….. None of which detracts from the fact that the lad done good…. |
Broad spectrum but software problem or fuel to cause a triple ECU failure?
|
Evalu8ter - I get that
At high weights and low airspeed it can be poorly placed….. I imagine current Merliners must be familiar with the story behind this, happily uneventful, event. airsound |
I believe it is as caused by freewheel units slipping leading to two engines shutting down through over speed and the third going to an idle power setting due to some FADEC logic. |
Some logic... two enigines shutdown and the FADEC puts the last Engine to Idle! That sounds just a bit odd. |

How to make a twin turbine helicopter even more complex. Add a third engine. :)
