According to the Globe and Mail, the S-92 failed a test to confirm the aircraft can run for 30 minutes without oil in the main gearbox.
Documents obtained by The Globe and Mail show that the S-92 failed a critical test of whether the aircraft can keep flying if the oil in its main gearbox leaks out, a key safety feature found in other makes of helicopter – including a model that was beaten out by the Sikorsky for the Canadian military contract. The delivery of the helicopters to the Department of National Defence has already been beset by a series of delays.
