The pilot stated he was in cruise flight at 500 feet agl when he observed the engine oil temperature gage just short of the red line. A short time later he heard a noise described as a 'pop'. He entered a power-on autorotaton to make a precautionary landing straight ahead to an open area, and planned to terminate at a hover. The engine out warning light was not illuminated, the engine out audio did not activate, and the remaining engine instruments appeared to be normal. The pilot initiated a deceleration at 50 to 60 feet, applied initial collective pitch at about 15 feet while increasing power and leveling the helicopter. The landing area was unsuitable and the N2 was observed decreasing. He applied aft cyclic, and the ventral fin collided with the ground. The helicopter rocked forward and the main rotor blades collided with the tailboom. Examination of the helicopter revealed a red shop rag was caught in the oil cooler fan. A rigging check was conducted and no deficiencies were noted. The engine was removed and placed in an engine test cell. The engine started, run at ground idle, and accelerated to takeoff power.
Probable Cause: The pilot's improper use of the cyclic during a power-on autorotative landing (low flare), resulting in the ventral fin colliding with the ground.
