Two 'very lucky' men survive light aircraft crash in field

A light aircraft plunged into a field north of Perth on Saturday, with the two men on board surviving the crash with non-life-threatening injuries.

Police said the pilot of the single-engine aircraft crashed near the Greenside private airfield, off Brand Highway in Muchea, north-east of Perth, this morning.

Emergency services responded to the incident, during which the aircraft sustained "significant damage", police said.

A man in his 60s and another man in his 30s were treated at the scene.

Department of Fire and Emergency Services (DFES) district officer Gareth Deeg attended the scene and said one occupant extracted himself from the aircraft, while the other person was assisted out.

"Without knowing the investigation and seeing the speed and the reasons behind it, any aircraft that comes on an abnormal landing is obviously critical," he said.

'Complex' crash site

The men were transported to Royal Perth Hospital at priority one, and St John Ambulance said they are believed to have non-life-threatening injuries.

Mr Deeg said several people at the airfield at the time of the crash quickly came to the aid of the two men.

He described the crash scene as "complex".

"It's complex for a number of natures: the location, the information that's provided, the fuel, the aircraft, what it's made out of," he said.

The Greenside Recreational Flyers Club, one of the state's largest, operates at the airfield, according to its website.

The aircraft crashed around 250 metres from the airfield's runway. Its fuselage, wings and tail were badly damaged.

Police said their inquiries are ongoing.
