The Australian Transport Safety Bureau (ATSB) has opened an investigation into the processes for the approval of buildings near airports in Australia.
The investigation stemmed from a report from a member of the public that an antenna erected on a building near Essendon airport in Melbourne posed a threat to aviation safety.
The ATSB says that it conducted an initial examination into approval processes for buildings and towers that pose a hazard to aircraft operating in the vicinity of airports.
It adds that this has "identified an underlying transport safety matter", and so it will now look into approval processes for structures near airports across Australia, as well as the interactions between the Department of Infrastructure and Transport and the Civil Aviation Safety Authority in support of that process.
Under ICAO convention, all signatory countries are meant to have regulatory protections in place to ensure that buildings do not impinge on areas where aircraft operate to and from an airport.
The ATSB expects to report its findings in March 2014.
