Accident Narrative
The helicopter departed from a residential gathering for a cross-country flight. The pilot, who had accumulated approximately 11,000 flight hours, reported a normal takeoff into the prevailing wind with a south departure. After reaching about 300 feet indicated altitude, the pilot initiated a left turn. During the turn, he felt vibrations, and his next recollection was being on the ground. The pilot did not report any mechanical malfunction to investigators on the Pilot/Operator Aircraft Accident Report.
Aircraft Examination
Examination of the fuselage revealed physical evidence consistent with downward compression and crushing, with deformation present to the left of the fuselage centerline. The left horizontal stabilizer exhibited physical evidence of ground impact, while the right horizontal stabilizer was not damaged. Flight control continuity was confirmed throughout the system.
Engine and Systems Inspection
The inspection of the engine and its components did not reveal any evidence of pre-impact failure. The main fuel control and the power turbine governor were examined and found to have no anomalies that would result in a loss of power, flame-out, or sudden overspeed condition. Additionally, a review of maintenance records did not reveal any overdue inspections or anomalies that could have precluded operation of the helicopter prior to the accident.
