A twin-engine aircraft crashed into a field near Bény, killing all four occupants after losing control in severe icing conditions during a flight from Vélizy-Villacoublay to Marseille.

What happened

The twin-engine aircraft was operating a scheduled flight from Vélizy-Villacoublay to Marseille. The crew consisted of one pilot and three passengers, totaling four individuals on board. During the en-route phase, the flight encountered deteriorating weather conditions characterized by severe icing.

As the aircraft progressed through these hazardous conditions, it lost controllability. The plane subsequently crashed into a field in Les Moulins des Ponts, located near Bény, approximately 18 kilometers north of Bourg-en-Bresse. The impact resulted in the total destruction of the airframe. All four occupants were killed in the accident.

Findings

Investigations indicated that the loss of control was linked to environmental factors affecting the aircraft's systems. It is believed that the flight controls became blocked as a direct result of the severe icing conditions encountered during the flight.

Probable cause

Flight controls were blocked due to severe icing conditions.
