The student pilot was performing a supervised solo traffic pattern after completing three successful patterns with a Certified Flight Instructor (CFI) on runway 33. The three practice patterns with the CFI had been done to determine wind effects and aptitude of the student on this day. As the student pilot completed his first solo traffic pattern and was coming into a hover he encountered a left crosswind from 250 degrees at 10 knots, and the helicopter yawed left and spun 1 1/4 turns. The helicopter then descended to a hard landing. The student and the instructor said there were no preimpact mechanical malfunctions or failures.
Probable Cause: The student pilot's failure to adequately compensate for the crosswind conditions and to maintain directional control.
