What happened
On May 27, 2011, an Aerospatiale AS 350 B-2 helicopter, operating as C-GSSS for Expedition Helicopters, was en route from a base camp located approximately 80 miles east of Big Trout Lake, Ontario, to a drilling site. During the cruise phase of the flight, the aircraft experienced an uncommanded left yaw following an in-flight engine shutdown.
In response to the engine failure, the pilot performed an emergency autorotation. The helicopter landed hard in shallow water near the shore of a lake. While the aircraft sustained substantial damage, there were no injuries to the occupants, all of whom exited the aircraft and reached the shore safely.
