Incident
A training aircraft operated on behalf of the Service de Formation Aéronautique & de Contrôle Technique (SFACT) was performing local training flights at Saint-Yan Airport. The flight involved multiple 'touch-and-go' maneuvers, all completed successfully.
Sequence of Events
After landing, the crew simulated an engine failure by reducing power on the left engine. While the aircraft was rolling on runway 33R, the flaps were mistakenly retracted from 30° to zero before the planned takeoff. As a result, the aircraft was unable to rotate into a nose-up attitude. It continued along the runway, overran the end, and eventually collided with the Instrument Landing System (ILS) antenna.
Aftermath
Both pilots escaped from the aircraft with minor injuries. The aircraft itself sustained damage beyond repair. The investigation determined that the inadvertent flap retraction prevented the aircraft from achieving the necessary lift for takeoff, leading to the overrun and subsequent collision.
