Analysis

The student pilot stated that he made several touch-and-go landings without incident, when the engine started "cutting out" on final approach. He reported that carburetor heat was not applied until after the power loss began. He was unable to restore power and elected to make a forced landing in a pasture. After maneuvering to avoid a fence and a road, the landing gear shear off during a crash landing and the plane slid to a stop. The engine was removed and examined, but no mechanical reason for a power loss was found. During a subsequent test run, the engine operated normally.
