Terrible news. My heart goes out to the families.

Looks as if the complete rotor head may have detached as opposed to just a blade.
Either way it would be terminal.

Seems the whole super puma fleet has been grounded?

Some more info here, entire rotor head disconnected 
Horrible, RIP!

The video of the rotor set falling to the ground is horrible. Poor folk.

Just saw the video on the News, complete rotor head and blades spinning down.
Seen many occasions of a blade detaching but never a complete rotor head. Even as a pilot, I would think twice of climbing into one again. In fact I used to hate travelling as a pax when I had to.

The rotor head unit falling like a sycamore seed - shocking.
Deepest sympathies to all affected by this tragedy.

Autorotation in the worst possible way.

last time this happened was when the ring gear failed in the epicyclic, (G-REDL).tut wrote:Just saw the video on the News, complete rotor head and blades spinning down.

What I don't understand is how a gearbox failure can result in the rotor-head detaching? the rotor-head loads are supported from the airframe, not the gearbox (via 3 struts).

Is it to do with the gearbox seizing and the rotor shaft continuing to rotate = shaft shearing ?

if that were the case, unless the shaft shears above the main thrust bearing, it's still attached to the copter.Mr Momo wrote:Is it to do with the gearbox seizing and the rotor shaft continuing to rotate = shaft shearing ?
from the pics, the whole rotor-head/shaft/etc are still attached, basically, everything above the gearbox.
(sure I read somewhere that if the gearbox craps out, the rotor can freewheel? may have been rubbish though)

I believe Eurocopter have a press release coming out today.
