Australia's air safety investigator has expanded a probe into a low fuel diversion incident involving a Virgin Australia Boeing 737-800 aircraft to include another aircraft.
The second aircraft, a Qantas Airways 737-800 registered VH-VYK, was operating on the Sydney-Adelaide route on 18 June, says the Australian Transport Safety Bureau (ATSB). As with the Virgin aircraft, registration VH-YIR, the Qantas aircraft was diverted to Mildura owing to low visibility conditions at Adelaide.
"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," says the investigator.
The investigation will explore areas which include the forecasting and distribution of weather information and the provision of weather information to aircraft affected by low visibility on 18 June at Adelaide. It will also look at how the weather information influenced the decision making of flight crews.
A preliminary report is expected by 18 July with a final report to be completed within 12 months.
