The pilot reported that he was in cruise flight when he heard a “pop” and the engine lost all power. He initiated an autorotation to a clearing, but was unable to reach it and had to land in an area with trees. The helicopter struck treetops during the descent and landed hard, sustaining structural damage. A postaccident inspection, including running the engine in a test cell, disclosed ample uncontaminated fuel, and no evidence of any preimpact mechanical problems with the helicopter’s engine or systems.
Probable Cause: A total loss of engine power in flight for undetermined reasons.
