Following three midair collisions at major general aviation
airports in Australia between February and July 2002, the
Australian Transport Safety Bureau (ATSB) conducted a review of
midair collisions in Australia between 1961 and 2003. The
objectives of the review were to identify common characteristics
and contributing factors, assess whether there had been a change in
the midair collision rate in recent years, and to compare the
characteristics and rate of midair collisions with those of other
countries.
