Narrative:
The helicopter had recently undergone an annual inspection and about a month thereafter the pilot planned to take it for a test flight. After completing an engine run-up, he noted that the helicopter appeared to be operating well. The pilot elected to perform a hover-taxi to a nearby helipad, which consisted of a flight path that would overfly a storage container. As he flew past the container, the helicopter’s engine experienced a total loss of power and he landed in a bark pile. During a postaccident visual examination by Federal Aviation Administration inspectors, they could not determine any problems with the helicopter’s engine. The pilot reported that following the helicopter being recovered he found a plug covering the fuel tank's vent line. The pilot opined that the plug resulted in the loss of power.
Probable Cause: The total loss of engine power for undetermined reasons.
