Emergency crews were called to Bunnan Road near Scone Aerodrome, about 150 kilometres north-west of Newcastle, at about 1:55pm. Police said the two occupants of the plane died at the scene, with inquiries now underway to identify the men.
A crime scene has been established and will be examined by specialist officers. The Australian Transport Safety Bureau said the aircraft involved was a kit-built aircraft on the recreational register. Recreational Aviation Australia, the national body for sport and recreational flying, has also been informed.
Upper Hunter Mayor Pat Ryan said he was contacted about the incident by the local airport general manager. "It looks like the aircraft has crashed adjacent to the airport on private property," he said. "Police are on the scene … sounds like a very tragic accident."
A report will be prepared for the coroner.
