| Confidence Rating: |  Accident investigation report completed and information captured |
The pilot reported that, during a maintenance release flight, he entered a simulated autorotation to check the main rotor rpm. When the pilot retarded the throttle, the engine lost power. The pilot subsequently conducted an off-airport landing. During the landing, the main rotor blade struck the tailboom, which then separated from the airframe.
During postaccident engine test runs in both the airframe and a test cell, the engine ran normally. Postaccident engine examinations revealed no anomalies that would have precluded normal operation. The reason for the loss of engine power could not be determined.
Probable Cause: A total loss of engine power during descent for reasons that could not be determined because postaccident engine examinations and testing revealed no evidence of an anomaly that would have precluded normal operation.
