What happened
During an approach to Lyon-Bron Airport, the flight crew encountered significantly reduced visibility caused by fog. While on final approach, the aircraft descended below the necessary altitude and made contact with telephone lines. This impact led to the subsequent crash of the plane in a field situated in Saint-Priest, approximately 2 km from the threshold of runway 34.
The accident resulted in the deaths of all three crew members on board. The aircraft involved was a vintage model originally manufactured in 1943 and had been part of the Air France fleet since April 20, 1953.
Findings
Investigations into the accident concluded that the pilot-in-command experienced a loss of visual references during the final approach due to the heavy fog. This lack of visibility meant the crew was unaware that the aircraft had descended to an unsafe altitude before striking the wires.
