Sikorsky announced today that Cougar Helicopters, part of Canada’s VIH Aviation Group (VIHAG), is the launch customer for its S-92A+ upgrade kit with an order for four. The kit features the new Phase IV main gearbox that uses a supplemental oil pump and additional oil lines to reuse main gearbox oil that is accumulated in a lower sump in the event of primary lubrication failure on the helicopter twin.
