The helicopter impacted terrain during an autorotation following a loss of engine power. The pilot reported he received indications of an engine over temperature on a prior flight and upon landing saw that the belt driving the cooling system water pump had come off the pulley. He put the belt back on the pulley and ran up the engine while confirming that engine temperatures were within limits. The pilot noted he completed a normal takeoff after allowing the helicopter to hover for three to four minutes as he checked the engine temperature. The pilot stated the water temperature began rising rapidly during departure and the engine "immediately" began losing power. The pilot reported the engine lost power a few seconds later and he lowered the collective to begin an autorotation. The pilot noted the helicopter yawed to the right as he flared. The pilot stated the helicopter impacted the terrain, yawed 45 degrees to the right, and rolled over onto its left side.
Probable Cause: The unqualified maintenance performed by the pilot and the inadequate autorotation by the pilot. A factor contributing to this accident was the overtemperature of the engine cooling system.
