Flight control systems involving a The Boeing Company 767-338ER, VH-OGD, Brisbane, Aerodrome, QLD on 10 September 1997

Soon after departure, the crew advised that the flight would be returning to Brisbane due to a hydraulic problem and requested that the fire services be placed on standby for the landing. The aircraft landed uneventfully a short time later and cleared the runway unassisted. Post flight examination found that a piston seal on the right outboard elevator power control actuator had failed. The actuator was replaced and the aircraft returned to service without further problems.
