I was told, on my 76 conversion, that the speed with which Sikorsky introduced the fix indicated that they already knew about the issue, and had been working on it. Without telling the operators. This was why Alan Bristow cancelled (most of) his 35 aircraft order. That might be apocryphal, but the source was around at the time.
Folk still climb aboard an S92 which is still basically the same as the Cougar machine? They may have fixed a few things but it still won't do 30 minutes with loss of lubrication or maybe I haven't kept up with things?
