On 15 May 1984, the pilot of the Cessna 340-A received warnings of fog over the intended destination of Goulburn. In order to prepare for the possibility of landing at another site, additional fuel was loaded. The pilot advised that the plane would land in Goulburn as scheduled, however it was noticed the aircraft was off course from the normal flight path and flying low over the city of Goulburn itself. The plane was seen to roll and descend steeply before hitting two houses. A fire broke out instantly. Three persons on board the plane and one person in one of the houses died.
