1 - History of the flight
The pilot, accompanied by a passenger, took off from Sion aerodrome (Switzerland) bound for Annecy aerodrome. During the landing run with a headwind on runway 22, the pilot noticed that the aircraft was veering to the right. He countered the movement by applying left rudder. He thought that he probably applied the left brake at the same time. The aircraft made a ground loop to the left, during which the right main landing gear folded under the fuselage. The aircraft then came to a stop on the runway.
2 – Additional information
The pilot, co-owner of the aircraft, held a commercial pilot licence CPL(A) issued by the Swiss authorities. On the day of the occurrence, he had logged around 800 flight hours.The aircraft is a two-seater tandem aircraft with conventional landing gear and high wings.
