Loss of Power
While en route at approximately 800 feet above ground level, the helicopter suffered a complete loss of engine power. The exact circumstances leading to the power loss were not immediately apparent, but the pilot initiated an emergency procedure.
Autorotation and Landing
The pilot executed an autorotation to a confined grassy area. During the descent, just prior to touchdown, the pilot had to maneuver the aircraft to avoid a person who was in the area of the intended landing spot. The helicopter touched down, bounced, and then experienced a skid collapse when it touched down a second time. The sequence of events following the power loss resulted in damage to the landing gear.
Inspection Findings
Following the incident, an inspection of the engine components was conducted. The examination revealed that one magneto condenser was shorting-out by arcing over its insulator base. Additionally, the second condenser was shorting-out where the lead wire was exposed through its insulation. These findings indicate the condition of the ignition system components at the time of the power loss.
