Outhouse - Water is about 400ft deep and they said that a recovery vessel will be there on Friday to start recovery process of wreckage.

May they all rest in peace.

How is it possible for a state of the art S-92 to go down only 7 minutes after a MGB oil pressure loss, bypass or no bypass. It is not possible according to Sikorsky reps. But still it did!! Have we not been told the truth about the MGB weakness?

Any technical history before the flight?

Praying for more survivors

Air Jockey - The chance of any more survivors are slim to none. The suits would have given them about 24 hours protection but that time has come and gone now, so things are not good.

This was posted on another website yesterday.

I trust it refects the truth.

Just listened to the evening news from NFLD. The search and rescue will be terminated and changed to a recovery mission for the A/C wreckage.

Sad days indeed.

Hope fades in N.L. chopper search

The search for 16 missing passengers of a helicopter crash off the coast of Newfoundland will end Friday evening, because officials say "the likelihood of finding survivors is no longer there."

13/03/2009 3:53:47 PM

A helicopter travelling from St. John's to the Hibernia offshore oil platform and operated by Cougar Helicopters ditched after experiencing technical problems, Thursday, March 12, 2009. The search continues Friday, March 13, 2009.


The announcement comes more than 30 hours after a chopper heading to an oil platform crashed into frigid waters with 18 people on board.

One survivor was rescued from the water on Thursday and is being treated in hospital for his injuries. One death has been confirmed but 16 others are now presumed dead.

"It appears there are no survivors," said the Joint Rescue Co-ordination Centre's Maj. Denis McGuire, adding that rescue crews had repeatedly searched a massive area of open water with no sign of life.

The search will officially end at 7:30 p.m. local time.

The operation will now be handed over to the Transportation Safety Board and the RCMP, who will conduct a missing persons investigation.

The chopper crashed and sank in 120 metres of water, and left a debris trail of about six kilometres.

Crash details

The helicopter was en route from St. John's to the Hibernia platform when the pilot reported mechanical troubles and turned back towards St. John's.

The chopper issued a distress call, and eight minutes later, went into the water.

"Mechanical problems were reported and we don't know of what nature," said Julie Leroux, spokesperson for the Transportation Safety Board.

It is believed that the pilot was "ditching" the aircraft, that is, making an attempt to intentionally crash-land the helicopter due to the mechanical problem.

The crew of a Provincial Airlines plane flew over the area within a few minutes of the crash and reported that the helicopter was floating upside down. The helicopter sunk shortly afterwards.

The missing aircraft is operated by Cougar Helicopters in St. John's.

Tragic; new equipment, professionally trained crew, company with an excellent safety record and leaders in the offshore support industry, passengers and crew trained on egress with all the right survival gear. What can I say-

Have they puplished the victims names ?

CBC is now reporting that the SAR mission has been handed to the TSB and is now being classified as a "recovery mission".

sad news.

I sit now with a heavy heart, at home in St Johns after having walked up my trail with my wife to throw a wreath in the ocean at 19.30local. Gods speed lads and lassies of this fair Isle, you will never be forgotten.

To you Mr Burt, my absolute and utter respects, to the way you handled the media at such a tough time, JJ and all the crews, we have done nothing but pray for your loss .
I fell very privaledged, when home, to live under the flight path of such a profesional operation.

We will not give up hope.

What a sad event.

Having read about considerations of loss of lubrication of the main transmission (though I am certainly not speculating, because I know nothing of this event) I am reminded of the concerns of a similar nature associated with the fixed wing LearFan of the early '80's. That aircraft had two engines driving one propeller, so it's intended redundancy of powerplants were considered in the context of a helicopter.

The gearbox design, included a block of wax within, which would melt at a suitably high temperature after oil loss for whatever reason. Cast into the wax were spring loaded electrical contacts, which closed once the wax melted. The closed contacts told the pilot that the gearbox was now being lubricated by the wax, and down would be good.

I hope we learn a lesson, which makes the cost seem, in the slightest way, bearable.

While flying Hueys for Uncle Sam the resident Bell rep advised the main transmission was good for either 30 or 60 minutes dry run, forget which. Had occasion to put it to the test and flew one for 15 minutes minus oil. Maintenance arrived fixed the problem (blown filter seal), filled with oil and they (not me) flew it home.

The certification requirement for dry run capability is contained in FAR 29.927, the relevent portion being

(c) Lubrication system failure. For lubrication systems required for proper operation of rotor drive systems, the following apply:

(1) Category A. Unless such failures are extremely remote, it must be shown by test that any failure which results in loss of lubricant in any normal use lubrication system will not prevent continued safe operation, although not necessarily without damage, at a torque and rotational speed prescribed by the applicant for continued flight, for at least 30 minutes after perception by the flightcrew of the lubrication system failure or loss of lubricant.


It is an uneviable position to be in should you have knowledge of the requirement, for you are presented with the dilemma do I follow the checklist and toss it in the water in sea conditions which make survival problematic, or take a punt and continue flight (SHORT) to a known safe haven (safe haven being defined as calmer water (lee side of ship perhaps), beach etc etc).

PS: A T-53-13 will run at take off power for 2 minutes minus oil. Thanks Mr Lycoming

I like many sat up and checked the news reports and prayed there would be reports of living victims recovered. That did not happen. I know there are many like me that are grieving the loss of the people aboard the Cougar flight.

My thoughts and prayers go out to those who have lost loved ones in this tragedy.

Its sad but all hopes are out too find survivors.

My they rest in peace and all thoughts goes to the one left behind.

Lets not speculate but wait for an answer and support those left behind and support them as good as we can.

What concerns me about this tragedy is that much has been said about the survival suits, the cold seas, the MGB, but what is missing is anything about the float system. One member mentioned something about the retrofit, but really, in those seas, without the floats going off, there is little time for the persons to get out without the aircraft filling up with water. If, like what has been alluded to, the aircraft crashed without any control, then floats may not have helped. If, however, the pilots were able to have some control and put the aircraft in without much airspeed and somewhat upright, then rolling over, we must have a float system assist the evacuation. I don't want to sound like this is the only issue, but just that the Canadian Cormorant that went down a few years ago, the egress lighting didn't go on as a result of the DC battery being ripped out. The result was that crew members in the back did not have any lighting to emergency exits. As aircrew, I am trusting that equipment installed on board should work when needed the most. I hope that Cougar's crews and pax didn't perish because of malfunctioning safety equipment.

Myt condolences to the families in the communities of Newfoundland and Canada waiting patiently for answers.

What we know from the news reports so far is that the aircraft was seen floating inverted a few minutes after impact, but soon sank. Doesn't sound like the floats were inflated once they were in the water, but maybe all four were damaged on impact or they were never armed. Good question for the 92 guys on the floats: do you fly with them armed over water (like the AW139), are you supposed to blow them before ditching or just put it in the water and wait for the water sensors to work, and will the sensors work inverted or does the float in the sensor have to go up (towards the belly) to make contact with the switch?

Is it known, whether the survivor is one of the passengers or one of the crew?

Arming the floats on the S-92 is a very handicapped procedure. Vy is 80 kts, Arming of floats is Max speed 80 kts..so there is an airspeed limitation to this. If you arm the floats Above 80 kts, you will gett a yellow caution visible all the way to the back seating row 10m behind you.
Best autorotation speed is 80-100kts. ARA`s are done >80kts. You see, the limitation is set to low, and will easily be forgotten in a stressfull situation like this. Seen many times in the sim that it is forgotten because you don`t want a yellow caution in your face.

Understand the impact was quite hard and the fuel tanks came of?

@Malabo

That reminds me to 2005 Copterline S76 crash, no emergency flotation deployment
