NTSB Narrative Summary Released at Completion of Accident

During a public use solo instructional flight the helicopter sustained substantial damage when it nosed over in a rocky, uneven field during a precautionary landing following an observed split in rotor/engine tachometer readings and an audible low rotor rpm alarm in cruise flight. The pilot perceived a mechanical emergency and performed a precautionary landing. The control box, tachometer cable, and tachometer were examined. The control box warning circuitry was not operational when first checked and operated after repair of an open circuit found on the circuit board. No anomalies were detected with the tachometer. Visual examination of the cable revealed indications of excessive wear and possible binding with windup of the outer strands. Binding of the cable is consistent with a bouncing tachometer needle.

NTSB Probable Cause Narrative

The binding of the main rotor blade's tachometer cable during cruise flight resulting in an observed split tachometer indication/aural alarm and perceived mechanical emergency and the unsuitable terrain the pilot encountered during the emergency landing. A factor was the rocky terrain.
