Probable cause & findings
THE CFI USED POOR JUDGEMENT IN GIVING A SIMULATED ENGINE FAILURE BY TURNING OFF THE FUEL SELECTOR VALVE.
Factual narrative
DURING A PRE SOLO INSTRUCTIONAL FLIGHT, THE FLIGHT INSTRUCTOR GAVE THE STUDENT A SIMULATED ENGINE FAILURE, WHILE IN THE AIRPORT TRAFFIC PATTERN, BY TURNING OFF THE FUEL SELECTOR VALVE. WHEN THE VALVE WAS TURNED BACK ON, THE ENGINE DID NOT RESTART IN A TIMELY FASHION AND A FORCED LANDING WAS MADE IN A FIELD. DUE TO SOFT TERRAIN, THE NOSE WHEEL DUG IN DURING LANDING ROLL AND THE AIRCRAFT FLIPPED ON ITS BACK. Source: NTSB Aviation Accident Database (Pre-2008 Archive) Retrieved: 2026-02-12
