Pax on board:
Aircraft left Paris-Le Bourget around 1500LT bound to Boufarik Air Base located near Algiers, with a crew of five, one employee of the National Bank of Algeria and a cargo consisting of fiduciary papers intended to the manufacture of bank notes. While flying at FL150, crew encountered icing conditions and elected to gain height. While climbing, aircraft went out of control and crashed in an open field near Saint-Germain-du-Teil, some 20 km east of Mende. All six occupants were killed.
In a preliminary report published in JAN2013, French BEA confirmed that the accident was the consequence of excessive frost accretion on all surfaces and airframe. Investigations were able to determine that the aircraft was flying at the limit of its performances in adverse weather conditions with dangerous phenomena such as the accretion of clear ice. This situation caused the frost alarm to activate, and the pilots to increase their altitude. At this moment, the plane went into a spin and the tail was sheared off due to aerodynamic forces that exceeded its design. Out of control, the aircraft completed several rolls before breaking up and descending to the ground.
