Overview
On an unspecified date, a certificated private pilot and three passengers experienced a complete loss of engine power during the initial descent phase. The pilot attempted the engine emergency procedures but could not restore power. A forced landing was initiated in an area surrounded by trees.
Accident Sequence
During the forced landing, the left wing of the airplane struck a stand of trees, causing the aircraft to pivot to the left. The pilot reported that the power loss occurred suddenly and that all emergency actions were taken without success.
Postaccident Examination
Investigators examined the aircraft after the accident. Fuel was present in both wing tanks, the fuel lines, and the fuel manifold assembly. No mechanical defects were found with the engine. The cockpit fuel selector valve was in the 'both' position.
Engine Operational Test
On September 7, 1999, the engine was operated while still mounted on the accident airplane's airframe. No anomalies were observed during its operation, and the engine produced full factory-specified rpm.
