Aircraft Accident/Incident Report
Chino, California 91710
Monday, September 1, 2003 17:20 PDT
NTSB Narrative Summary Released at Completion of Accident
The helicopter's main rotor struck the tail boom while the pilot was practicing a run-on landing. While the student pilot was attempting to execute a landing, he touched down on the heels of the skids. The helicopter rocked forward and the pilot pulled back on the cyclic. As a result, the main rotor blades made contact with the tail boom. No mechanical problems were noted with the helicopter. The student pilot had accumulated about 58 hours in helicopters, with 7 as pilot-in-command. The operator reported that students were not permitted to practice run-on landings during solo flight.
NTSB Probable Cause Narrative
the student pilot's inappropriate remedial action through the application of excessive aft cyclic during a run-on landing. A factor in the accident was the student's disregard for company procedures.
