Primary finding
Probable cause
The student pilot's failure to maintain aircraft control while performing pedal turns at a hover, resulting in a collision with terrain.
Investigator assessment
Analysis narrative
During a supervised solo, the student pilot was practicing 360 degree circles in a hover practice area at the airport. During the maneuver he reached a point perpendicular to the prevailing wind, and added right torque pedal to compensate, with minimal result. The student pilot then added power to regain control, and the helicopter started to continuously rotate to the right and began climbing. After reaching about 100 feet, and completing approximately 5 revolutions to the right, the helicopter descended, and impacted the ground in a flat attitude, resulting in substantial damage.
