The 2nd July update by atsb says:
Update: 2 July 2013
The ATSB is continuing its investigation into the circumstances surrounding the diversion of a B737 aircraft, registered VH-YIR (YIR) and operated by Virgin Australia, to Mildura, Victoria on 18 June 2013. The reduced visibility at Adelaide Airport, South Australia that led to the diversion also affected a number of other aircraft, including another B737. This aircraft, registered VH-VYK and operated by Qantas, was en route from Sydney, New South Wales to Adelaide before also diverting to Mildura.
As a result of its increased understanding of events, the ATSB
has expanded the scope of its investigation to examine both of these diversions and their broader context. The investigation title has been amended to reflect this expanded investigation focus, which will include examination of the:
- forecasting and distribution of weather information by the Bureau of Meteorology
- provision of weather and operational information by Airservices Australia to all aircraft that were affected by the reduced visibility at Adelaide
- provision of weather and operational information to those aircraft by the operators
- influence on the flight crews’ decision making of that information flow.
A preliminary factual report into the circumstances of the occurrence is anticipated by 18 July 2013, and the final report is expected to be completed within 12 months.
Let's see if atsb can meet their self imposed deadlines!!!
