The aircraft was parked about 40 metres from its hangar. After carrying out a normal daily inspection the pilot boarded the aircraft with the intention of conducting some practice circuits and landings. As soon as the engine was started it developed full power, the aircraft accelerated rapidly and collided with a truck which was parked in the hangar. The pilot had not flown for four months and most of her experience was on a more basic aircraft type. The pre-flight and engine start sequences were attempted without using the checklist. After the engine had started the pilot tried to reduce power but did not depress the throttle-lock of the vernier control. It is possible that the cabin heat control, which was selected on, could have been mistaken for the park brake, which was not set, as they are both situated in the same panel.
