The engine oil systems are separate from each other and the MRGB.
Probably debris from the last overhaul.
Except for common mode failures like fuel contamination. Max You might want to ask how well fuel QC / fuel system maintenance is done at your installation.
Max Ae Cougar flying PC2e to reduce exposure to hitting the deck or sea when an engine fails during offshore take off?
Probably debris from the last overhaul.
Jim L has provided statistical data that shows two engines failing almost simultaneously is so remote a possibility as to be of almost no concern.
the 92 is designed to fly well on a single engine

Thanks for the feedback guys, much appreciated. I still find it strange for both engines to have chip issues so close together, perhaps a bizarre co-incidence.
Wrt. PC2e utilization I have no information on that, I did a quick search of the TSB report and safety inquiry reports on 491 and there is no mention of PC2e. Perhaps one for the more learned and informed members of this forum to respond to.
Wrt. fuel QA/QC, again I trust the oil companies and fuel suppliers to ensure that QA/QC within acceptable tolerances is achieved. Using my layman's perspective I would assume that it is cost advantageous to maintain high fuel quality in order to minimize operational wear on the engines as well as maximize operational life.
This specific a/c (call sign KKN) was flying around all weekend most likely on test runs (the airport is quite close to my house and adjacent to the golf course where I walk my dog). I'm heading back offshore soon so will have a chat with the Cougar lads when I'm up at the heliport, they are really good at answering PAX questions.
Safe flying

I have heard from a friend that a CHC S92 is stuck on a deck offshore in the Danish sector with a crack in the gearbox.

I am very glad it was not a foot crack. That would have been a difficult one. it was confirmed to me today that it was not a foot crack so we will wait for the official report. I also believe it is not a completely new fault.

Sikorsky hasn’t paid $8M fine for late helicopter delivery
This was in the papers the other day on the maritime helicopter program and the contractual penalties for the ongoing delays.

What is unclear is when the first interim helicopter will be delivered to the Defence Department.
In its attempts to help Sikorsky along, DND officials reduced the criteria for the interim aircraft to receive a military airworthiness certification. But even with that Sikorsky failed to meet its delivery timetable, according to a November 2010 briefing note for Defence Minister Peter MacKay.
The Citizen obtained that note through the Access to Information law.
The reduced criteria would have allowed for safe flying of the aircraft but the helicopter would have been restricted in what it could do. It would not have been allowed to fly over water or at night, according to the briefing note.

The pilot of the S-92 which performed a 74 kt run-on landing at Galliano after suffering LTE (see post #1977) has been selected to receive one of the HAI's 2012 Salute to Excellence awards:
I/C
Pilot of the Year Award: Jay Slagle, Captain, Bristow Group.
Jay Slagle is recognized with the 2012 HAI Pilot of the Year award for his efforts to successfully land an eleven ton helicopter after loss of tailrotor effectiveness. Inbound to Bristow’s Galliano Base, a Sikorsky S-92 with 14 souls aboard began an uncommanded nose-right turn as the aircraft slowed, and which worsened as power was reapplied. Recognizing an imminent emergency, Slagle and fellow Captain Chuck Melton diverted to a nearby airport with a 6,500’x100’ runway where, while maintaining 80 knots, they flew the S-92 onto the runway without an effective tailrotor, using differential braking once on the ground to bring their aircraft to a controlled stop.

Very well done!
The NTSB have yet to issue a probable cause:
CEN11IA156
Looking back I see there was a claim that the US operator was being secretive about the cause & lessons:
http://www.pprune.org/6257963-post1988.html
Any more information on that?

S-92 Galliano
Just an observation re the S-92 behavior in the conditions cited:
The tail rotor was still rotating at proper rpm, and because of the inherent cross beam design, and the way the airfoils are mounted to the composite beams, and mindful that there is no pitch change hinge ( pitch change occurs thru physically bending the crossbeam ), the tail rotor is not at zero thrust. (Yes, I realize that the centering spring is not in the loop in this condition ).
Thanks,
John Dixson

Tip of the cap to the crew running it on.
For what it's worth (John Dixson already knows this) LTE and loss of thrust are not one and the same.

Hi there,
I am working on a PPT presentation for a ground school initial training program on the S92.
Does anyone in here have jpegs pictures of all the different displays that can be selected on all the MFD pages?
I have tried to take a few pictures of our machines (on the ground and in flight), but the quality was not that great!
Thank you for the support!
