Primary finding
Probable cause
The pilot's failure to maintain directional control during the air taxi with shifting winds.
Investigator assessment
Analysis narrative
While air-taxiing the helicopter away from the runway, the helicopter encountered an unexpected gust of wind while passing near a hangar. The private pilot lost control of the helicopter and was unable to regain control before the helicopter's tail rotor impacted the ground. The helicopter subsequently landed hard and remained in the upright position. Neither the pilot nor the passenger were injured. An onscene examination of the helicopter by Federal Aviation Administration inspectors failed to reveal any preimpact anomalies. The pilot reported that there were no known mechanical malfunctions or failures.
