Accident Details
The accident occurred during a low-level eagle survey mission. The helicopter was cruising at a speed between 20 and 30 miles per hour. The pilot flew up a canyon and was crossing a ridge at an altitude of approximately 150 feet above ground level (AGL) when wires became visible ahead.
Sequence of Events
The pilot initiated evasive action upon sighting the wires. However, the helicopter struck the wires. The impact tore the tail rotor and gear box from the helicopter. Subsequently, the helicopter began spinning.
Pilot Actions
The pilot attempted to regain control by lowering the collective and retarding the throttle to stop the spin. However, the pilot found that neither throttle nor collective control was available. The helicopter then crash landed.
