Systemic Investigation into Factors Underlying Air Safety Occurrences in Sydney Terminal Area Airspace


Following three breakdown of separation occurrences in the airspace of the Sydney Terminal Area (TMA), the Bureau of Air Safety Investigation (BASI) initiated a systemic investigation into the common factors underlying those occurrences. The investigation commenced on 22 June 1998 and was completed by 31 July 1998. Three further occurrences were identified during the course of the investigation.

The systemic investigation has identified safety deficiencies primarily related to the management of change, and the rate and complexity of change faced by air traffic controllers operating in the Sydney Terminal Control Unit over the last four years. Resolving these management issues will further enhance the safe operation of aircraft in the airspace of the Sydney Terminal area. This report contains nine safety recommendations that have been developed to address identified safety deficiencies.
