 The Queensland Coroner's Inquest in 2007, found that, despite evidence that there were a number of issues leading up to the crash, pilot error was the prime cause.Families of those who lost their lives in the disaster have been highly critical of the Coroner's findings and the deficiencies in the operations of the regulator, the Civil Aviation Safety Authority (CASA), and the poor company structure and practices of Transair Ltd.The investigation was aided by flight information from the aircraft's flight data recorder.
