Lost engine power whilst hovering over a Coast Guard ship. The helicopter collided with the ship, fell into the water and sank.

In the accident, while conducting the rescue hoist training, in which the aircraft was hoisting up a personnel from the ship deck, the aircraft’s No.1 engine failed, followed by ditching and capsizing, and occupants of the aircraft sustained serious injuries.

It is considered possible that ice chunks were sucked into the engine leading to an engine failure, however, the cause of the failure was not determined because the engine of the aircraft was not recovered.
