Probable cause
The pilot's inadequate compensation for a tailwind while hovering, which resulted in a loss of directional control.
NTSB analysis
While hovering, the student pilot lost directional control, and the helicopter spun around to the left 3 1/2 turns before it impacted the ground and rolled over after the right skid collapsed. The pilot reported that there was a tailwind of about 5 knots. The helicopter sustained substantial damage to the tail boom and the main gear box frame. The pilot said that there were no preimpact mechanical malfunctions with the helicopter.
