A helicopter experienced a hard landing while practicing an autorotation. A certified flight instructor (CFI) and a commercial rated pilot who was receiving flight instruction were on board. The CFI stated that the commercial pilot entered the maneuver, executed the 180 degree turn and continued the descent until reaching 50 to 60 feet above the ground, where the commercial pilot initiated the flare. The CFI reported that immediately after the flare, the helicopter began to yaw to the left. The CFI stated that he instructed the commercial pilot to correct the yaw and align the helicopter straight with the ground. The CFI reported that he "came on the cyclic" to assure a straight track was achieved. A hard landing was encountered, resulting in the main rotor blades striking the tail rotor drive shaft and tailboom.
Probable Cause: The commercial pilot not maintaining directional control of the helicopter and the improper flare initiated before landing.
