Aircraft Accident/Incident Report

NTSB Narrative Summary Released at Completion of Accident
The student pilot stated that he conducted a preflight inspection and engine run-up and noted no anomalies. He departed and climbed to 2,000 feet when the engine started running rough and popping. The engine rpms dropped from 2,200 to 2,000 without the throttle being moved. The pilot leaned the fuel mixture until the engine reached peak temperature and then enriched the mixture to -30 degrees. The engine roughness and popping increased and the rpms began to drop. The pilot then made a forced landing to a pasture. The airplane collided with several fixed objects and sustained structural damage to the airframe. Examination of the airframe, flight controls, engine assembly and accessories revealed no anomalies. The Pilot's Operating Handbook specified that in case of engine problems the mixture control should be set to "rich".
NTSB Probable Cause Narrative
A total loss of engine power due to the pilot's improper leaning procedures, resulting in a forced landing and collision with a fence.
