Aircraft Accident/Incident Report
Fortuna, California 95540
Monday, April 23, 2001 16:00 PDT
NTSB Narrative Summary Released at Completion of Accident
The student pilot was practicing hover autorotation maneuvers. Three hover autorotations had been conducted jointly, with both the student and the flight instructor on the flight controls. The fourth attempt was to be done with only the student holding the fllight controls. According to the instructor, when he reduced the throttle to initiate the practice hover autorotation, the student lowered the collective so abruptly that he could not prevent a hard landing. After landing, the helicopter rolled onto its side.
NTSB Probable Cause Narrative
The student's improper procedure during a practice emergency that exceeded the instructor's reaction capability.
