Narrative:While maneuvering during a test flight, the gyroplane impacted terrain following a loss of rotor rpm. Witnesses reported that the gyroplane departed the runway to the south and made a 180 degree turn to a northerly heading. At the mid-point of the runway, the gyroplane entered a left turn. A witness stated that he noted a decay of rotor blade speed and then observed the main rotor blades contact the tail section. A second witness stated that he heard 'rotor blades slowing down.' The gyroplane impacted terrain in a nose low attitude and was consumed by fire. The airframe and engine were examined, and no anomalies were found that would have prevented operation of the aircraft.
Probable Cause: The pilot's failure to maintain rotor rpm while maneuvering, which resulted in the main rotor blades contacting the tail section of the gyroplane.
