Probable cause
The pilot’s failure to maintain rotor rpm during an autorotation after a perceived partial loss of power, which resulted in a hard landing. Contributing to the accident was radio frequency interference with the governor controller, which resulted in an uncommanded decrease in throttle and the perceived loss of engine power.
