While manoeuvring the aircraft on the ground the pilot accidentally increased engine power; the aircraft moved forward and struck a fuel bowser and an adjacent low wall. The pilot considered that the cause of the accident was the inadvertent power increase which resulted from catching the throttle in the sleeve of his flying suit. He concluded that there may have been an air leakage in the landing gear air system, which resulted in the air pressure depleting more quickly than usual and thus causing the loss in braking effectiveness.
