"- We have four regular flights to Draugen per week and we are currently working to find alternative helicopter suppliers for our operations in Norway in this temporary situation."

REDL is a L2 a different design of MGB it's same if you compare a rabbit and a hare it's look like similar but different....
And REDL have so many alert (ignored) before the crash , this is the result of lot of chips and corrosion!!!!!

Bristow Grounds Airbus EC225 Helicopters After CHC Crash - WSJ
Reads like they have ruled out gearbox failure to me which is quite concerning because if it wasn't the gearbox responsible for ripping the head off the aircraft, what was it?
Oh well, enough speculation, I guess we will find out at the press conference tomorrow where their area of interest is.

Bristow ground EC225 - wsj article
I have copied and pasted the whole article from wsj site:
The fallout from Friday’s deadly crash of an Airbus Group SE helicopter widened Monday as investigators begin analyzing black box data that could explain the cause of the accident.
Bristow Group Inc. on Monday said it would ground some EC225 helicopters in Australia, after regulators in Norway and the U.K. barred passenger flights with the model.
The company said it was suspending flights of six of its EC225 helicopters in Australia, but that three others used for search-and-rescue operations would continue to be used. In Norway and the U.K., where Bristow has a number of the helicopter’s registered, the model has also been grounded for emergency operations.
On Friday, an EC225 flown by CHC Helicopter Services crashed while flying to Norway’s Bergen Airport from Statoil AS A’s Gullfaks B oil field, killing all 13 people onboard. The cause of the accident is still unknown.
Norway’s air accident investigators said Monday that data from the combined flight data and cockpit voice recorder had been extracted. “The data is of good quality and is sent back to Norway for analysis,” the Accident Investigation Board Norway said. The U.K. Air Accident Investigations Branch extracted the information.
The rotor appears to have separated from the helicopter, a highly unusual occurrence.

There's an 8-K been put out by BRS today:
Bristow Group Inc. - SEC Filing
Essentially just says how many aircraft affected in which regions. All grounded bar life-saving SAR.

Thanks for the clarification Pablo, wasn't sure myself but as you say in the event of 'Jesus nut' failure on other aircraft types that have the nut installed, you lose the head from the mast rather than the mast from the MGB.

The Main rotor flight controls run under the No2 Engine (grandfather design rights). Power turbine disk intrusion has been addressed allegedly by contained blade shedding. Gas generator turbine disk failure has not been looked at.

1. Suspension bar lower end (rotated through about 150 degrees to point up) which attaches to the forward or aft lifting frame. This would indicate that part, if not all of the ring above the conical housing detached with the rotor head.
2. Broken pitch rod - upper end rotated through about 180 degrees.
3. Scissor link clevis but scissor link detached
4,5,6 Blade dampers outboard ends detached. The detached plate for the outboard end of the damper at 5 has rotated to face out. Normally, when still attached to the rest of the damper assembly it would face inboard. Damper assemblies at 5 & 6 have rotated to point up whereas assembly at 4 has rotated to point down.

Apologies VortexRinger, I meant only to state that it was the lower end of the suspension bar. I was looking at a picture of a complete MRH head at the time which had the blue blade in the forward position and directly above the forward suspension bar. Earlier post now corrected.

I don't believe they have ruled out gearbox failure. They have just ruled out the vertical shaft issue that caused the previous 225 ditchings.
"Airbus Helicopters said initial evidence suggested no link with two previous incidents in Scotland involving Super Puma H225 helicopters."
Still seems to closely similar to G-REDL to believe at the moment that it could be anything other then the gearbox locking up. Which I guess as in G-REDLs case, was an isolated incident to that variant (AS332L2). Airbus may already be considering this an isolated one off incident in the H225. It is a different aircraft and the only time (if it is the case) it has happened.
That said, the fact that Bristow has suspended 225 flights would make one believe that it is NOT maintenance related on CHCs behalf. Why would they park millions of dollars worth of aircraft if they knew it was a maintenance issue by the other operator .... Same token, I guess in today's downturn, being able to park aircraft at customers expense while putting other assets to work may not sound to bad.
As far as the 225 goes, would be hard to think it's going away. There isn't enough aircraft out there to fill the role and as a few have already said, there isn't an aircraft that can do it for the price ... Full pax, full fuel. At the end of the day Big Oil comes down to profits ... They will have their "advisors" inform them what they want to hear and the 225 will be back in service. Wasn't to many years ago everyone was calling for the S92s head, petitions signed, pax refusing to board, etc.

Ahem Satcomm, I am one of those "advisors" and let me assure you that in our company, we advisors present unbiased recommendations to management regardless of the current economic situation in the resource sector. In this particular case, our recommendation is NOT to fly this POS until cause is determined and rectified.

Don't know if this has been posted prior, CAA Norway has revealed the main gearbox of the accident helicopter was replaced on January 17. CHC then had the rotor head replaced on March 27.
".......the fact that Bristow has suspended 225 flights would make one believe that it is NOT maintenance related on CHCs behalf. Why would they park millions of dollars worth of aircraft if they knew it was a maintenance issue by the other operator "
Presumably, because the National authorities (CAA and NCAA) have grounded the EC225 for all but emergency flights. Didn't give Bristow a lot of choice. I don't see how this decision points to any conclusion at this early stage.
Saw a reference to a Press Conference today. When is that?
