Report on air accident at Skjelbreia in Ski, Akershus on 2 April 2009 with Diamond DA40-D, LN-NEX

Aviation report 2013/26 eng

While practicing steep turns at 2 000 feet in connection with pilot training, all thrust from the propeller was suddenly lost. The aircraft made a forced landing on the ice-covered lake Skjelbreia. At the end of the roll-out the aircraft turned over in a river pool and came to rest with its cockpit partially under water. The two persons on board managed to evacuate the aircraft, with some difficulties. The accident did not result in serious injuries to the persons on board. There was significant damage to the aircraft. The loss of thrust was caused by failure of the clutch in the power transmission between the engine and the propeller. The AIBN believes that the clutch failure was probably a result of insufficient dampening in the clutch spring mechanism.
