Narrative:
The student pilot departed on his second solo flight in the helicopter. Before the accident, he completed two takeoffs and landings without incident. During a subsequent practice autorotation, the tail rotor struck the ground, the helicopter entered a spin, and it then came to rest near the place of initial impact. The student pilot reported that there were no mechanical or system malfunctions with the helicopter before the accident. The flight instructor who witnessed the accident stated that the deceleration/flare was executed too low.


Probable Cause: The student pilot's delayed and improper landing flare during a practice autorotation, which resulted in the tail rotor striking terrain.
