The Sligo helicopter was sent to do the pick up of the injured crew while the Dublin crew was there to follow as a backup and keep communications as a safety measure.
Could someone flesh out the benefits and risk matrix on having a second helicopter involved?

He clarifies his preference of departure runway with the comment;

"We are quite heavy here with fuel"

Weather was poor at Blacksod last night. 116 had made contact for a refuel at the lighthouse. 116 apparently terminated the first approach and was in the process of attempting a second approach when contact was lost.

AIS shows it heading out beyond Black Rock before turning around and heading roughly back toward Blacksod before the signal disappears around Black Rock.

There was ADS-B and it shows the aircraft crossing the country and crossing the Ballycroy hills at 3500 feet. However, there does not appear to be ADS-B coverage at low level in the area of the accident, so things like altitude just prior to the accident is not available.

The CHC / ICG S92s are Mode-S only, the positions on FR24 / Planeplotter etc are MLAT guesstimates. At the time of introduciton there was no certified ADS-B transponder for the '92.

However they do broadcast GPS-derived position on AIS, which is not considered a safety-of-flight system.

Folks....immediately speculating the Tail Rotor Bearing issue played a role in this is exceedingly premature and does not needs to be a part of this thread yet.

How about holding such comments and limiting such speculation to known facts like weather, mission issues, and most importantly status of the people on board the aircraft!

Is not the welfare of the crew, passengers if any, their families and friends the most important thing right now?

It is interesting to see someones head has a 180 turn when comes to his soft spot.

SAS, logic would dictate that in the event of a no mayday being issued that it was either a CFIT or a mechanical failure. Something that happened suddenly and unexpectedly.

Fair enough on the TGB speculation, it's just that is fresh and as we seen previously happens very suddenly and has the potential to be catastrophic. From Swiss Cheese's post above about a terminated first approach to the lighthouse for a refuel only to go missing on the 2nd approach with a last position about 1-2nm from the lighthouse would most likely indicate a CFIT. (If SC's information is accurate)

Some reports saying weather was fine, some saying bad and some saying it was manageable. The lighthouse would have provided a good visual reference in good conditions.

I guess all we know is that it was sudden, be that CFIT or Mech fail, only time will tell. Naturally speculation will always happen on a discussion forum like this.

My understanding of the Tail Rotor issue is that it results in effectively a 'fixed pitch' situation. It does not result in complete loss of tail rotor thrust.

Whilst this needs to be managed by the crew, it seems unlikely to be "potentially catastrophic".

Worst case being for it to happen approaching the hover over a helideck! (sound familiar?)

My thoughts are with those affected by this tragedy.

Apate, there is video footage of the incident on the West Franklin from the helideck camera which provided the AAIB all they needed for their report along with matching this up with the FDR plots. The helicopter spun 180 before planting itself back on the deck, from what I am told it should have resulted in the loss of the aircraft due to the very quick uncontrolled spin. The fact it was only a metre or 2 off the deck saved the aircraft, the crew and the passengers so from my understanding it does have the potential to be catastrophic.

There are no other known failure modes that i am aware of on the S92 other than the filter bowl incident and that would be a little far fetched considering the Cougar crew had ample time to deal with it.

Needing fuel, missing the 1st attempt and coming up short on the 2nd attempt is also interesting with regards to fuelling but surely not?

The O&G industry is on tenterhooks right now.

Weather reports are difficult to come by, but Shannon reports 24 hours. It is not on the coast and some distance away, but does offer some indication of the kind of weather that might have been experienced:

Not any more than normal. O&G has already been told that there is no evidence of technical failure at this stage. Our S-92s will continue flying normally on crew change ops unless different information is received.

Sad loss

SAR crews are a widespread but still a family community and the tragic loss of this crew will be felt by all. I was lucky in seeing out my 25 years on SAR with only minor incidents to look back on but I will never forget the comeraderie nor the friends who were taken from us. Sincere condolences to the families of those dedicated aircrew lost doing a vital job they all enjoyed.
I hope the investigation has an early result as it must be very worrying to those still flying in the role but in the S92 in particular and should stop any further unhelpful conjecture.

Very, very sad news.
I remember Dara arriving in Aberdeen some 20 years ago to accumulate S61 time flying offshore, before returning to SAR in Ireland.
A lovely, friendly and obviously very capable lady to achieve the position and status she had reached.
Thoughts are with her family, the other crew members still missing and their respective families.
God Bless.

Very sad news, the Coast Guard lost a volunteer member last September too. Thoughts with the families and colleagues of the crew.
