NTSB Narrative Summary Released at Completion of Accident

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.

NTSB Probable Cause Narrative

The pilot's inadequate compensation for a tailwind while hovering, which resulted in a loss of directional control.
