The reciprocating-engine powered helicopter lost engine power while in cruise flight. The 115-hour student helicopter pilot reported that the helicopter was in cruise flight at 1,500 feet when he "felt a change in torque or something." The pilot activated the carburetor heat and the engine power slowly decayed. The pilot initiated an autorotation to a marsh area. During the forced landing the main rotor blade contacted and separated the tailboom assembly. Post-examination of the airframe and engine did not reveal any pre-impact anomalies. The carburetor heat control was found in the automatic mode, the engine sparkplugs appeared normal, and there was approximately a half-tank of fuel in the helicopter's fuel cell. The reason for the reported loss of engine power could not be determined.
Probable Cause: The loss of engine power for undetermined reasons. A contributing factor was the lack of suitable terrain for the forced landing.
