## Probable cause

A misalignment of the rotor system drive belt, which resulted in belt chaffing, its subsequent separation, and a resultant loss of power to the rotor system.  Also causal was the relatively low altitude and airspeed at which the separation occurred, which inhibited the pilot's inability to maintain a level attitude during the autorotation.
