Accident to the Robin DR400 registered HB-KBX on 08/07/2022 at Culoz

During a flight between Yverdon-les-Bains and Lyon-Bron, an overcurrent in the electrical system of the aeroplane caused the protective sleeves of some cables to fuse together and the appearance of electrical continuity. The magneto cables became connected to the aircraft ground, leading to the engine ignition system being cut off and then the engine shutting down. The pilot carried out an off airfield forced landing during which the right wing collided with the ground and the aeroplane turned over. The cause of the overcurrent leading to the overheating of certain cables behind the instrument panel could not be determined.
