The certificated flight instructor (CFI) and his student were practicing a 180-degree autorotation with a power recovery occurring at the hover. The helicopter's sink rate increased dramatically in the flare, about 40 feet above the ground. The CFI initiated a go-around by increasing power, raising the collective, and pushing the cyclic forward. The helicopter continued to descend and contacted the runway in a level attitude. After it came to a stop, the CFI confirmed that the main rotor blade had struck the tail boom. The instructor reported that there were no preimpact mechanical deficiencies with the helicopter.
Probable Cause: The flight instructor's failure to maintain control of the helicopter during a practice autorotation, which resulted in a hard landing.
