Incident Overview
A private pilot was conducting a cross-country flight when the engine began running rough. A loud bang was heard, followed by a partial loss of engine power. Smoke entered the cockpit, and oil pressure was lost, prompting the pilot to initiate an emergency landing.
Sequence of Events
During the approach to a dirt road intended for the landing, the aircraft's landing gear struck powerlines. This contact apparently damaged the aircraft's brake system. After touchdown, the brakes were inoperative. The aircraft departed the left side of the road, went through a fence, and collided with a rock. The impact sheared off the nose gear, and the aircraft nosed over.
Post-Accident Findings
A post-accident inspection revealed that the number two piston had disintegrated, which was consistent with the engine malfunction experienced during the flight.
No other factors or conclusions were reported regarding the cause of the piston failure or the accident sequence.
