Departure airport:Manassas, VA (HEF)

Investigating agency: NTSB
Narrative:
The pilot receiving instruction was performing a practice autorotation from about 1,800 feet above ground level. During the touchdown, the pitch of the helicopter increased excessively and the tail rotor and stinger contacted the runway. The certificated flight instructor took authority of the helicopter's controls and lowered the pitch to arrest the tail-low condition. The helicopter began to shudder and both pilots manipulated the flight controls in an attempt to maintain aircraft control. The helicopter then struck the runway in a left-skid-low attitude. A postaccident examination of the wreckage revealed that the tail rotor was separated and the vertical stabilizer was severed. The pilots reported no mechanical anomalies with the helicopter during the autorotation.
Probable Cause: The pilot receiving instruction's failure to maintain a proper pitch attitude during the practice autorotation maneuver.
