I'm not sure what your point is on the windscreens. I don't think Squib was being critical of Sikorsky's own S-76 windscreens and there is no suggestion Cougar cause their accident by changing the S-92 gearbox!
Sikorsky is the Type Certificate Holder. They applied for the certification and it is their duty to meet the requirements and justify why and how they do.
However as Sikorsky are a US company and the FAA certified the aircraft before the JAA or Transport Canada perhaps the FAA should come clean on their decision making on 927. Did they bow to pressure from Sikorsky?
MOST CRTICAL
If the oil flows out of the gear box the oil temperature sensor will not see any oil and while the gears get very hot - the indicated oil temperature will not rise. You have just made the sort of mistake that perhaps convinced the Cougar crew to delay ditching. The CVR transcript will indeed be interesting.
