Shell have suspended all flying in Norway with CHC (at least temporarily). Some grumbling among Shell workers in the UK, who have been told to turn up to CHC as normal (this is the third CHC accident in Europe since Shell moved to them).

1.I know nothing about aerodynamics.
2.As a merchant mariner I have a tenous grasp of hydodynamics.
3.I presume that the main rotor continues to rotate in the normal direction, clockwise in this case, when it detached.
4. This is the case with a ships propellor when a drive shaft fails.
5. Question is why is the majority of damage to the blades on the trailing edges.

The LE spar is constructed of glass fibre roving strips impregnated with resin and is relatively strong.
Best nautical analogy from a strength point of view would be to think of the LE as the mast and the trailing edge as the sail.

It is very sad what happened, nevertheless, I am an EC225 driver for years and AS332 for décades, I truly rely on this Aircraft. So wait and see what is going to be published this afternoon.
By the way Johni, are you not on the Sikorsky payroll?

Nope, I think EC make some great aircraft, but I think this is the death-knell for the 225. They only just managed to restore confidence after the last two crashes.
I think the S92, EC175, AW189, AW169 etc would easily be able to fill the gap. Sure, the 225 has good lift/fuel capacity, but at what cost?

The S92 and EC225 had some design weaknesses that caused ditchings, and in the case of the 92, fatalities. Ditto 139. Historically new types have always had design weaknesses. It seems incredibly naive to presume that the 175, 189, 169 do not. It is just a matter of time before they manifest the problems.

And now the petition is over 20000 signatures. Have to respect the passengers (families) concerns.
Condolences to crew and pax families
@HeliComparator post # 368. An AW139 threw a TR blade in Hong Kong causing the whole TGB assembly to depart the scene resulting in a ditching and loss of the aircraft (no fatalities however).
Profitable event for the company concerned, they received both a hull loss insurance payout and compensation from AW.

IIRC, 139 t/r blades issue. Back to this tragedy, it just 'appears' that several failures focused on MGB/ MGB area. Recall that a witness stated seeing a fire on top of the Norway 225 prior to ground contact.

That's a fair point Mitchaa, but the petition calls for the EC225 (sic.) to be removed not the AS332L/L1/L2. Just the 225. From memory, before this accident (which I am certain now that you will find is not linked to the L2 break-up - watch this space - Think fwd suspension bar airframe attachment) there have been a ditching due to the oil pump drive shaft fracture and one ditching due to pilot error (ETAP?).
Apart from (most of) the airframe, to all intents and purposes the 225 is a completely different aircraft to the L, L1 and L2.
Unfortunately the public see the airframe and think they are all the same. They are not. Just like a B733 bears little or no relation to a B738.
