Transair was an airline based in Australia. The Civil Aviation Safety Authority cancelled the Air Operator's Certificate, at the request of Transair, on 4 December 2006.[1][2] Transair ceased all operations from that date. This action followed investigations by the Civil Aviation Safety Authority and Australian Transport Safety Bureau into the airline's safety after the fatal accident of one of Transair's aircraft on 7 May 2005.[2][3]
