Accident Details
The pilot was herding cattle when the helicopter entered a gentle right turn at approximately 25 mph and an altitude of about 20 to 30 feet above ground level (AGL). During this maneuver, the pilot noted a sudden loss of engine power.
Pilot Actions
In response to the power loss, the pilot lowered the collective and entered an autorotation to an open area directly ahead of the aircraft. The autorotation was executed to reach a suitable landing site.
Landing and Impact
During the landing, one of the landing skids sank into the dirt. This caused the helicopter to pitch forward, resulting in the main rotor blades impacting the ground. The helicopter sustained damage from the rotor strike.
Fuel Status
Prior to departure from the ranch, the pilot stated that the fuel gauge read between 5/8 and 3/4 full, equivalent to 13 to 14 gallons. The pilot also reported that the low fuel warning light did not illuminate before the loss of engine power. Following the accident, the fuel tank was found to be empty at the accident site.
