Summary
A student pilot conducting a supervised solo instructional flight encountered a total loss of engine power while descending after practicing upper air maneuvers. Attempts to restart the engine were unsuccessful, prompting a forced landing in an open field. During the landing roll, the airplane struck brush and trees, resulting in damage. Post-accident examination of the engine revealed no evidence of mechanical failure, and it ran to full power on a test platform. Weather conditions at the time were conducive to the formation of carburetor ice, and the pilot did not report using carburetor heat while maneuvering.
Narrative
According to the official investigation, the student pilot was performing a supervised solo instructional flight that included practice of upper air maneuvers. While descending from such maneuvers, the engine lost all power. The pilot attempted to restart the engine but was unsuccessful. Subsequently, the pilot selected an open field for a forced landing. During the landing roll, the aircraft struck brush and trees, causing damage.
Investigation
Following the accident, investigators examined the engine but found no signs of mechanical failure. The engine was later run up to full power on a test platform and operated normally. The investigation noted that weather conditions at the time of the accident were conducive to the formation of carburetor ice. Additionally, the pilot did not report having used carburetor heat during the maneuvering phase of the flight.
