Narrative:
[I was] hover taxiing at approximately 20 ft and 20 KTS. Heard a belt break and snap against the inside of the cowling of the engine compartment. [I] immediately noted loss of tail rotor effectiveness. Lowered the collective almost all the way down intending to autorotate but I was too slow to lower it all the way. The helicopter started to turn to the left with the small torque remaining. I started turning the throttle off to stop the turn. I was over a smooth grass infield between the runway and taxiway so I tried a run on landing once I got the turn stopped. Landed in complete control with good rotor RPM remaining and tracking straight at about 5 KTS but landed a little too hard and collapsed the skids. This type aircraft is known for weak skids. No injuries.
