Narrative:
The student was executing a practice power-off autorotation, and during the go-around from the simulated landing flare he applied too much aft cyclic. The instructor, who was simultaneously applying a small amount of up collective to arrest a slight sink, did not take adequate remedial action to keep the student (who is a high-time fixed wing pilot) from applying too much aft cyclic. This resulted in the tail rotor of the helicopter impacting the ground, followed immediately by a loss of tail rotor effectiveness. Soon thereafter, the helicopter began to spin, and the instructor pilot took over total control and executed an emergency landing. After the aircraft's engine was shut down, it was determined that there was damage to both the tail rotor and tail boom.
Probable Cause: The dual students failure to maintain clearance from the terrain during the go-around from a simulated autorotational flare, and the instructor pilot's failure to take adequate remedial action to keep the dual student from allowing the aircraft to impact the terrain.
