The single engine aircraft crashed on take off from Rennes Airport, killing the pilot, sole occupant.

During the take off run, the right engine lost power and the aircraft started to turn to the right. The pilot tried to correct this but his reaction was excessive so the aircraft turn left and veered off runway, rolling towards the airport building. The pilot immediately retracted the gear so the aircraft sank and slid for several yards before coming to rest. While there was no casualties, the aircraft was written off.
