AT THE COMPLETION OF A DAY VFR FLIGHT THE AIRCRAFT LANDED ON A HOMEMADE LANDING/HANDLING DOLLY AT A PRIVATE RESIDENCE. DURING THE ENGINE COOL DOWN PROCEDURE THE RIGHT SIDE OF THE DOLLY FAILED. THIS CAUSED THE AIRCRAFT TO ROLL OVER TO THE RIGHT REAR DIRECTION WHILE THE ENGINE WAS RUNNING AND ROTOR SYSTEM TURNING. THE MAIN ROTOR STRUCK THE GROUND ALONG WITH THE TAIL ROTOR.
