The crew took off from Lyon Saint-Exupéry airport at 14:02 with two cabin crew and 25 passengers, bound for Marseille Provence. At destination, they carried out an ILS approach to runway 13L.

Twelve seconds after wheel touchdown, at a speed of around 70 kt, the captain detected an anomaly and then, three seconds later, announced “fault on MFC ... fault on both MFCs“ and that he no longer had control of the aeroplane. In his statement he said that the steering wheel did not respond to his actions and that he had the impression that the brakes were not acting normally. He decided to use the emergency braking system.

During the landing roll, the aeroplane deviated from its path, first to the right and then to the left, coming to a halt two thirds along and slightly off the runway. The nose gear was found at 90° to the longitudinal axis of the aeroplane.

The passengers disembarked from the aeroplane and were taken to the terminal by bus.
Inspections carried out after the incident found hard braking marks on the runway and reported that the MFC 1B and MFC 2B FAULT lights were on.
