On 4 March 2013, a Beechcraft Premier 1A stalled and crashed soon after take off from Annemasse. The Investigation concluded that the stall and subsequent loss of control was attributable to frozen deposits on the wings which the professional pilot flying the privately-operated aircraft had either not been aware of or had considered insignificant. It was noted that the aircraft had been parked outside overnight and that conditions had favoured frost formation. The presence of a substantial quantity of cold-soaked fuel had favoured frost formation. The presence of a substantial quantity of cold-soaked fuel in the wing tanks overnight was also noted.
