The aircraft landed on runway 26 at Saanen aerodrome. During roll-out the aircraft collided with a de-icing truck parked on the runway, in front of the displaced threshold 08. Causes: The accident is attributable to the fact that a landing was carried out even though at that time a vehicle was still on the runway. This meant that the aircraft, in the course of its landing roll, collided with this vehicle. The following factors contributed to the accident: – The excessively high approach speed on final approach led to an increased landing distance. – The pilot had had little actual training on the aircraft type involved in the accident and in operation on short runways. The identified systemic cause was a runway occupancy concept which had safety deficiencies in various respects.
