The pilot, accompanied by his wife, took off from Belle-Ile-en-Mer (Morbihan) for a VFR flight bound for Lille.
In cruise, a failure of the alternator led to a sudden reduction in the electrical power supply voltage followed by the illumination of a warning light indicating a battery problem. The pilot decided to divert to Amiens then, due to a deterioration in climatic conditions, to carry out an emergency landing. A witness on the ground saw the aeroplane pass at a low height with the emergency parachute deployed.
The failure of the alternator was due to the thrust waster being incorrectly assembled in October 2011.
