Incident Summary
During a downwind leg, the pilot reported activating the carburetor heat and immediately reducing power. Shortly thereafter, the engine stopped. The pilot attempted to restart the engine while executing emergency procedures, but the engine did not respond.
Sequence of Events
As the aircraft continued, it touched down short of the intended runway. After touchdown, it traveled approximately 25 feet before nosing over onto its back. The pilot had communicated the actions of pulling the carburetor heat and reducing power just before the engine stoppage.
Examination Findings
A subsequent examination of the engine revealed no mechanical failure or malfunction. The engine was found to be capable of normal operation, indicating that the stoppage was not due to a mechanical defect.
