The pilot was flying passengers for 5 minute sightseeing tours. Shortly after departing with two passengers and while at 75 feet AGL, the pilot stated that he experienced an unexplained loss of RPM. The pilot reversed course using right pedal to turn back to the point of departure. While maneuvering to avoid obstacles and with a tailwind, the pilot stated that the rotor RPM further decayed. The helicopter impacted the ground hard, and the main rotor blade severed the tail boom. No mechanical problems were reported by the pilot, nor was any fuel contamination found. A Federal Aviation Administration Inspector started the engine twice without finding any mechanical malfunctions.
Probable Cause: The pilot's failure to maintain rotor RPM.
