What happened
During a local training mission, an aircraft of the type Dove was performing circling maneuvers in the vicinity of Bankstown Airport. During this period, the aircraft collided with a Piper PA-30-160B Twin Comanche, registered VH-WWB, which was arriving at the airport from Sydney. The impact caused both aircraft to descend rapidly into a residential neighborhood situated approximately 3 NM from the airfield.
The collision resulted in the total destruction of both planes. There were four fatalities in total, representing all occupants on board both aircraft. While the crash occurred within a populated area, no injuries or deaths were reported among people on the ground.
Findings
Reports indicate that the crew operating the Dove may have been experiencing radio communication difficulties prior to the mid-air impact.
