On 13 July 2012, a Gulfstream G-IV left the side of the runway at speed during the landing roll at Le Castellet following a positioning flight after ineffective deceleration after the flight crew had forgotten to arm the ground spoilers. The Investigation found that pilot response to this situation had been followed by a loss of directional control, collision with obstructions and rapid onset of a fierce fire. Contributory factors identified included poor procedural compliance by the pilots, their lack of training on a relevant new QRH procedure which Gulfstream had ineffectively communicated and ineffective FAA oversight of the operation.
