EC225 crash near Bergen, Norway April 2016
 
Helicopter crashes off Norwegian coast


OSLO (Reuters) - A helicopter with 13 people on board has crashed off the west coast of Norway, rescue services and media reported on Friday.

Several people could be seen in the ocean, while the helicopter was on a small island, an eyewitness told news channel TV2.

TV2 images showed plumes of smoke rising from the site.

"Helicopter crash: Emergency services at the scene. Extent of damage unknown," the regional fire brigade said on Twitter.

Quoting local police, newspaper Verdens Gang said the helicopter had 13 people on board.

The area just west of Bergen, Norway's second largest city, sees frequent helicopter traffic to and from offshore oil installations.

Eyewitness reports on nrk saying he looked up after hearing a strange noise then saw the rotor departing left and the chopper body dive over to the right.

TowerDog 29th Apr 2016 11:08

Some reports says no survivors, other sources say some survivors in water.
Rotor blades came off in the air, then a violent explosion according to eye witness.
13 SOB.

EC225 crash near Bergen, Norway
 
An EC225 has crashed on an island a few NM west of Bergen, Norway at 1150 CEST. The helicopter was inbound Bergen from the oil drilling rig "Gullfaks B". The initial reports from the police state no survivors recovered so far. Number of pax not confirmed, but the local news claims 11 + 2 crew.

Eye witnesses report of the main rotor coming off in mid air, others claim the entire helicopter was spinning uncontrollably before it impacted the ground and exploded quite violently on the small island of Turøy just west of Bergen airport.

Very sad to hear this news. Not sure if there are any survivors. Even though I worked for the opposition for most of my 40 years + flying, I did contract for CHC. My thoughts are with you all who are affected by this terrible accident

Not good.

FleurDeLys 29th Apr 2016 11:50

Scarily reminiscent of 85N, albeit a 225 rather than L2. Horrendous. Sympathies and condolences to all involved and affected.

SE210 29th Apr 2016 12:11

Sounds like G-REDL.

Super Puma, where the rotor gear box failed causing the rotor to detach.

gulliBell 29th Apr 2016 12:15

...and they were almost home.

If the rotor comes off in flight there won't be any survivors, simple as that.

TODALADA 29th Apr 2016 12:39

Info from Flightrdar 24 suggest LN-OJF is the chopper.

TowerDog 29th Apr 2016 12:47

Eye witness reported hearing a loud bang, or explosion, then pieces of the rotor came flying though the air, (some folks had to run so as to not get hit) then the helicopter came down on a rock, then rolled or fell into the water.
Some witness reported the rotor blades hit the ground after the helicopter came down.

Pure speculation: Could a big bird have caused this kind of damage, or a drone-collision?

TowerDog - in danger of jumping on the bandwagon. Heathrow was more than likely a plastic bag.

Well it might be possible.

I think that catastrophic gearbox failure is more likely in this case. And it has happened before with pretty much the same result.

Flugplatz 29th Apr 2016 13:08

How high would it have been flying on an rig-flight? assume well above those powerlines?

Well, the EC.225 Super Pumas are now grounded by Statoil. (The owner and operator of the oil rigs on the Norwegian side of the North Sea.)

GearDownThreeGreen 29th Apr 2016 13:17

11 confirmed causalties so far and still no sign of the missing two. The fuselage is resting 6 meters below the surface but the main rotor has separated and is located on a nearby island.

Very grim indeed...

At this distance from it's destination, the chopper would barely have started it's descent and so would have been a few thousand feet above any power lines.
Everything is speculation right now but I would think the cause will be found to be related to the EC225 and not any external factors.

Oh how quickly the non-rotorheads ask stupid questions.
Lets just wait and see shall we.

TowerDog 29th Apr 2016 13:43

An eyewitness on the ground looked up just as the rotor was separating and said he saw flames or a fire on top of the helicopter.

Cloud surfer 29th Apr 2016 13:45

Probably a red herring, but near-collision (50-100m) with a drone at 5,000' south of the airport last week.

Bergensavisen - Drone var 50?100 meter unna Widerøe-fly

The helicopter was at 3,500 and 150kts when it entered into a rapid descend according to FlightRadar24.

Whether this will turn out to be another gearbox issue or something entirely unrelated we simply cannot say yet. What we can predict is that the Super Puma's reputation in the oil business is probably beyond repair

susier 29th Apr 2016 13:58

According to the FR24 data I saw, a gradual descent began at 09:51 UTC, from 3250ft and at 09:54, at approx 2225ft the speed dropped rapidly from around 140kts to 64kts within a few seconds.


At this point radar data appears to end.


I'm sorry I don't have more detailed data. This is just from ordinary playback/graph thus may be inaccurate.

johni. We have no choice when we are sent offshore. It's a case of get on the chopper or lose your job.

It's quite strange because most offshore guys hate the pumas and prefer the S92s but I have talked with pilots on here before and they find the EC225s better than S92s (i believe because of the flight systems). When we are in Pumas, we are packed in like sardines and have very little room to move, unlike the S92s, which are more like a bus, they just feel a lot safer from a passenger's perspective.

Yes and perspective or perception is critical. With the history of problems Statoil will now worry about putting people back on an aircraft which fairly or otherwise is perceived to be unsafe. It will be much less risky from a PR point of view to simply change the aircraft type they use.

Looks like a stable descent from 3000'** to 2000'** probably under ATC instruction given the range to the airport. About 1 min after levelling out something catastrophic happens with a 10deg yaw to the right, and rapid loss of altitude and airspeed, given the eye witness reports of the loss of main rotor and the fact it was found 300-500m from the rest of the wreckage the crew wouldn't have stood a chance.

RIP

** =I'm assuming the ALT given on FR24 wont reflect QNH/QFE

zorab64 29th Apr 2016 14:21


speed dropped rapidly from around 140kts to 64kts within a few seconds.
. . . which, if the blades or XMSN separate at 140kts, would tie in with a rapid reduction in forward flight and a possibly short continuation of transponder/radar returns (depending on electrics lost) as forward speed translates quickly into vertical. It doesn't bear thinking about.

Another sad day - thoughts are with the families.

Grounded by Petrobras on Brazil, too...

The entire rotor is located in one piece minus one blade it seems. Don't know when that blade has come off.

TowerDog 29th Apr 2016 14:40

And now grounded by the Norwegian Civil Aviation Authorities. (Avinor)

Avinor is not Norwegian CAA... "Luftfartstilsynet" is the CAA

birmingham 29th Apr 2016 14:52

The Luftfartstilsynet ban applies to the EC225LP and is until further notice.

Aser 29th Apr 2016 14:52

Sad day :(
but good and quick reaction by Norway :ok:

RIP and condolences to all the families and friends, thoughts also go out to the CHC SAR aircrafts searching the scene, not easy knowing its one of your own

Yikes! That is the whole rotor head come off.. There but for the grace of God..wishing the berieved much strength and courage in dealing with their loss and the aftermath of this crash.

TorqueOfTheDevil 29th Apr 2016 15:38

Very sad news. RIP fellow Rotorheads and pax.

dipperm0 29th Apr 2016 15:43

My condoleances to the family and relatives.

This accident reminds me 20 years ago, when an Alouette 2 lost its main rotor while on final. Inquiry reveals that the accident was caused by a human error who used the wrong nut to secure the rotor hub on the rotor mast - The Al 2 and 3 rotor hub to mast attachment were using similar but not identical nut.
