Incident
On a positioning flight from Morlaix to Dijon, a twin-engine aircraft was cruising at FL230 when it entered a left turn. The turn was followed by an uncontrolled descent during which the aircraft partially disintegrated. Wreckage and debris were strewn across more than 8 kilometers, with the main impact site located in an open field near Saint-Broladre. The pilot, who was the sole occupant, was killed. The pilot did not issue any distress call prior to the loss of control.
Investigation
Investigators documented the debris field and examined the aircraft components. The flight had been routine until the sudden deviation. The aircraft's altitude at the time of the event was FL230. The reason for the left turn and subsequent loss of control could not be determined from the available evidence. No distress call was made by the pilot.
Probable Cause
The official probable cause of the accident was loss of control for unknown reasons.
