The aircraft landed on 25 February 1994 at Trollhättan Airport, where an inspection was to be carried out. Two days later the aircraft was to resume operation.
According to the crew all items on the checklist were performed in connection with start-up and preparations for taxiing. Nothing abnormal was noted. When after engine start-up and prior to taxiing the captain moved the propeller control from FEATHER to TAXI, the aircraft started to roll forwards. The captain and the first officer then attempted several times but without result to brake the aircraft using the toe-brakes and the parking brake. After moving some 25 metres the aircraft collided with a terminal building. The stop was gentle and no personal injuries were incurred.

Probable Cause:

Causes of the accident: The accident was probably caused by the pre-takeoff taxiing being commenced without full hydraulic pressure being available for the brakes. Contributory has been an unusual feature of the design that may give rise to a temporary loss of braking pressure. This possibility was not known by the operator, nor was it mentioned in the flight manual.
