Confidence Rating: Accident investigation report completed and information captured
While aggressively maneuvering over the shore and ocean, below 100 feet above ground level, the helicopter experienced a total loss of engine power. The pilot entered an autorotation, and activated the float system. The helicopter impacted the water in a level attitude, but with enough forward speed to become submerged and then bounce 15 to 18 feet back into the air. The helicopter impacted the water a second time, but this time inverted. Both occupants egressed the submerged helicopter, and were rescued shortly after reaching the surface. A postaccident examination of the helicopter revealed main rotor blade damage consistent with a loss of power; however examination of the engine and powertrain were inconclusive.

Probable Cause: A loss of engine power due to undetermined reasons.
