| Confidence Rating: |  Accident investigation report completed and information captured |
The pilot said he was flying the helicopter about 1,000 feet above ground level when the engine began sputtering. He said the engine sputtered until the helicopter was 500 feet above the ground and '...then the engine quit.' The pilot said he flared too late during the autorotation and the helicopter's tail struck the ground. He said the helicopter rolled onto its side during the ground collision sequence. The on-scene investigation revealed no mechanical anomalies with the engine or airframe that would prevent flight. Inspection of the fuel system revealed its vent line was plugged by a Mud Dauber Wasp. The fuel system does not have a vented cap. The fuel vent line is located on the bottom of the helicopter's fuselage and is visible to the pilot.
Probable Cause: was an inadequate preflight and misjudged flare to landing during the autorotation by the pilot. A factor in this accident was a totally blocked fuel tank vent system.
