Aircraft Accident/Incident Report

Rialto, California 92376

NTSB Narrative Summary Released at Completion of Accident

During a practice full-touchdown autorotation, the main rotor blades struck and severed the tail boom. The certified flight instructor (CFI) said that the purpose of the flight was to prepare the commercial pilot (student) for his CFI check ride and they were performing full touchdown autorotations. The helicopter was aligned with the centerline of the south taxiway. At 60 feet agl, the student flared the helicopter and then leveled it for a full touchdown autorotation. When the helicopter was 1 foot agl, the student pushed the cyclic forward and the forward tips of the skids touched the ground. The helicopter rotated aft, and the CFI assumed the controls and leveled the helicopter. Upon touchdown, the main rotor blades contacted the tail boom. The CFI noted no mechanical malfunctions with the helicopter.

NTSB Probable Cause Narrative

the student pilot's improper use of the cyclic control during a practice autorotation, and the inadequate supervision by the certified flight instructor.
