| Confidence Rating: |  Accident investigation report completed and information captured |
Shortly after departure, the pilot observed the engine-out caution light and received an audible alarm. The pilot then saw the automatic re-ignition light illuminate. Since the engine appeared to be operating at a reduced power setting, the pilot elected to perform a run-on landing. During the landing, the helicopter encountered a ditch, and the tail rotor struck the ground. A postaccident examination of the helicopter found that the fuel control governor limit switch, located on the pilot's collective, was set near the minimum limit (low power setting). No other anomalies were found with the airframe. The engine was removed and run on a testing system with no defects noted. According to the helicopter manufacturer, the warnings and power reduction that the pilot observed were consistent with the position of the limit switch as found. Therefore, it is likely that the reduction in engine power resulted from the improper setting of the governor limit switch.
Probable Cause: The pilot's failure to ensure that the governor limit switch was properly set, which resulted in reduced engine power.
