Preliminary report released July 2011

At 2302 Eastern Standard Time on 30 June 2011, an Airbus A320 aircraft, registered VH-VNC and operated by Tiger Airways, conducted a missed approach procedure after an unsuccessful approach to land on runway 18 at Avalon Airport, Victoria. The flight crew contacted air traffic control (ATC) and was directed to climb to 3,000 ft and, after further discussion, to position as required to return to Avalon for a landing on runway 36. During that re-positioning, the flight crew left the assigned altitude without clearance and descended to 1,600 ft, which was below the minimum safe altitude for that area of 2,000 ft. The aircraft landed on runway 36.
