ATR 72-201, EI-REH
Following an uneventful flight, the aircraft came to a halt on stand and the crew applied the parking brake. However, the aircraft subsequently started to move forward once more and, despite attempts to stop the aircraft by using the brakes, it continued to move until it struck a stand guidance mirror assembly. The investigation determined that a failure of a hydraulic fuse in the parking/emergency brake line had led to a loss of the brake accumulator hydraulic pressure.
