During a local training flight, an aircraft veered off the runway after the instructor shut down engine number 4 to simulate a failure. Both pilots were uninjured, but the aircraft was damaged beyond repair.

Incident Overview and Context An aviation incident occurred at Clermont-Ferrand-Aulnat Airport during a local training flight. The event took place while the aircraft was on the ground, specifically during the takeoff roll. The flight was being conducted by a crew consisting of an instructor and a pilot-in-command, with the purpose of training. The source does not specify the aircraft type, registration, date, or operator, so these details are not included in this report. The incident is notable for the deliberate action taken by the instructor to simulate an engine failure, which led to a loss of control and a runway excursion. The outcome was significant, as the aircraft sustained damage that was assessed as beyond repair, although the human casualties were minimal, with both pilots remaining uninjured. This event highlights the risks associated with training exercises that involve simulated failures, even when conducted under controlled conditions on the ground. The fact that the aircraft was damaged beyond repair indicates that the loss of control and subsequent excursion resulted in substantial structural or mechanical damage, likely from the impact with the grassy area or the forces involved in the veering off the runway. The absence of injuries to the pilots is a positive outcome, suggesting that the crew may have been prepared for the simulated failure or that the nature of the excursion did not result in a high-impact collision. However, the total loss of the aircraft underscores the potential severity of such incidents, even in training scenarios. The incident serves as a reminder of the importance of proper procedures and risk assessment during training flights, particularly when simulating critical failures that can lead to loss of control. The location, Clermont-Ferrand-Aulnat Airport, is a known aviation facility, and the incident likely prompted a review of training protocols and safety measures to prevent similar occurrences in the future. The source provides a concise account of the events, focusing on the key actions and outcomes without delving into the specific technical details of the aircraft or the exact sequence of the loss of control.
