What happened
During a scheduled local training session at Clermont-Ferrand-Aulnat Airport, the flight crew was performing maneuvers to practice emergency procedures. As the aircraft type was accelerating during its takeoff roll, the instructor intentionally deactivated engine number four to replicate an in-flight power loss scenario.
Following this manual shutdown, the pilot-in-command was unable to maintain directional control of the plane. The aircraft drifted toward the right side of the runway and exited the paved surface, eventually coming to a stop in a nearby field. While there were zero fatalities and no injuries reported among the two crew members, the incident resulted in the total loss of the aircraft due to structural damage sustained during the excursion.
Findings
- The engine shutdown was a deliberate part of the training syllabus.
- The primary factor in the accident was the pilot's inability to maintain the runway centerline following the simulated failure.
