It was on March 12, 2009 that Cougar Helicopters Flight 91 departed St. John's en route to the SeaRose FPSO in the White Rose oil field and Hibernia Platform in the Hibernia oilfield off the coast of Newfoundland 55 kilometres east-southeast of St. John's.

The Cougar Sikorsky S-92A ditched. There were 18 people on board. One survived.

A Mayday call was issued after the aircraft reported zero oil pressure in the main gearbox at 9:40 am.

Flight 91 attempted to return to St. John's but went down at 9:48 am.

The aircraft was spotted, floating upside down, by a Provincial Airlines ice patrol airplane 25 minutes later. It later sank in 178 metres (584 ft) of water.
