Please note that this information is the result of cooperative effort between the ATSB and the aviation industry as a whole. The data quality and consistency is fully dependent upon the reporting efforts of the industry where no follow-up action is undertaken by the ATSB.
The ATSB investigates air safety occurrences for the sole purpose of enhancing aviation safety. Consequently, the ATSB material is confined to matters of safety significance and may be misleading if used for any other purpose. In this regard, please note that anyone using this information to cast blame for these occurrences on any individual or group of individuals does so without the endorsement of the ATSB.
The ATSB also wishes to make clear to all users of the enclosed information, that the information cannot, by itself, be used to compare the safety of either individual operators or aircraft types.

The time of day these incidents occurred is of particular interest. The likliehood of under reporting incidents, particularly when the Parafield tower is unmanned, (e.g. after 6PM), is a matter worthy of concern. Extensive flight training occurs at Parafield after dark, often there is more night circuits flown than during the day. Then there is no supervision from the Parafield’s tower, and all circuit training remains untracked on radar in Adelaide. The public cannot report incidents, as aircraft registration numbers are not identifiable (this is even so during the day, where the last digit/s have insufficient contrast to be visible due to training aircrafts’ colour design). The sheer volume and density of overflights make using place & time domains impractical for normal human beings to identify aircraft.
