| Confidence Rating: |  Accident investigation report completed and information captured |
The pilot reported that during the takeoff initial climb from a private airstrip, the engine began to surge, and erratic propeller rpm and engine torque readings were displayed on the engine instruments. The pilot initiated a 180-degree turn back to the departure airport, and about halfway through the turn, the engine lost complete power. The pilot initiated a forced landing in the direction of the departure airport and landed hard. A postaccident examination of the airframe and turbine engine revealed no evidence of mechanical malfunctions or failures that would have precluded normal operation. The engine was subsequently removed from the airframe and installed on an engine test stand. The engine was run at various power settings with no anomalies noted.
Probable Cause: A total loss of engine power during takeoff initial climb for reasons that could not be determined because postaccident examination did not reveal any anomalies that would have precluded normal operation.
