The pilot and passenger of the helicopter were conducting a wildlife survey when the engine and main rotor began to lose rpm. The pilot lowered the collective, rolled the engine throttle control to full power, and attempted to regain the engine and main rotor rpm without success. The pilot conducted a forced landing to an opening in the canopy of vegetation below the helicopter, during which the helicopter rolled over onto its left side, resulting in the separation of the tail boom and substantial damage to the fuselage and main rotor.
An examination of the helicopter and engine revealed no mechanical anomalies that would have precluded normal operation; and the reason for the loss of performance could not be determined with the available information.
Probable Cause: The loss of helicopter performance for undetermined reasons.
