Aircraft Accident/Incident Report

Tuesady, July 22, 2008 17:25 MDT

NTSB Narrative Summary Released at Completion of Accident

During takeoff initial climb at an altitude of about 100 feet above ground level, the climb performance of the airplane degraded along with a partial loss of engine power. The certified flight instructor (CFI) advanced the mixture to the full rich position, checked the carburetor heat, and verified that the throttle was full forward. The CFI then took control of the airplane from the student pilot, and initiated a forced landing into an open soft field. During the landing, the wheels of the airplane sunk into mud, and the airplane nosed over. Examination of the engine, fuel system, and airframe systems related to engine operation revealed no anomalies that would have precluded normal operation.

NTSB Probable Cause Narrative

A partial loss of engine power for undetermined reasons.
