Aircraft Accident/Incident Report

Prineville, Oregon 97754
Sunday, September 15, 2002 9:30 PDT

NTSB Narrative Summary Released at Completion of Accident

The student pilot reported that he flew the gyroplane down to about 11 feet above the runway surface for landing. He then pulled the control stick back to level the aircraft. The student pilot stated that the aircraft ballooned a little so he pushed the stick forward. At this point, the aircraft was about 12 feet above the runway and it began to rapidly descend. The student pilot applied power to arrest the sink rate, however, the rotor speed had decayed and the aircraft landed hard with no forward airspeed. After touchdown, the aircraft bounced and tilted to the left. The rotors contacted the runway surface and the aircraft came to rest on its left side. The student pilot reported no mechanical failures or malfunctions with the aircraft at the time.

NTSB Probable Cause Narrative

The student pilot's failure to maintain airspeed resulting in a hard landing.
