Am I missing something here?

At what stage of "approached the platform" did this occur? Was the aircraft was on autopilot or not? There was an unexplained altitude drop yet the pilots found the aircraft was "serviceable" and flew back to Halifax?

Was it the aircraft or was it close to the platform and suffered a mechanical or flare induced altitude drop?

Sounds to me like there was a bit of a c--k-up and they gave themselves a fright. Possibly getting close to sea water interface.

Sikorsky's incident notification mentions a descent, yaw, and NR decay.

NR decay. Might be very expensive. Like that Bristow S76C++ NR decay in Nigeria that the crew hushed up but which was subsequently discovered by maintenance. I think the whole power train got scrapped.

That was CHC/Aero, if itís the same incident. Delaminated the blade roots and a drag damper detached from a blade.

Well, hushing it up is impossible. Far to many protocols in place.

Rumour is that this S92 dropped the AC Generators offline due to the Nr decay!
If that rumor is true, ouch. Nearly every major component has become nothing but mere anchor weight. Curious as to what phase of the approach the crew were in. There have been very similar incidents over the years. Although some NR decay was noticed not to the point were the gens dropped offline.

There has? Any references?

As someone who has been flying the aircraft since 2006 and has contacts in most companies at reasonably high levels, your statement surprises me.

I suspected you'd highlight this total mishandling of a departure.

However your original statement said "similar incidents over the years". I'd suggest that this one rather unique event doesn't quite fit your original assertion.

I find one passage very interesting.

"The decision was made to terminate the captainís employment based on the companyís determination that the captain could not operate safely in the offshore IFR [instrument flight rules] environment," the report found.
How was that "determined"?

What was the basis for that "determination"?

Shock Horror! - Over-reliance on automation leads to crew 'cock-ups' - no great surprise there.

Just the entire drivetrain, engines should be ok. More expensive is loss of reputation from their selected, trained and qualified crew getting themselves into that situation.

See remedy in above posts.

Yes it was much better when we had ex-Whirlwind RAF pilots flying S-61s like G-BDII 31 years ago....,

.....And that pilot was retrained, retained and rehabilitated to a different operation.
