A pilot has been seriously injured after crashing his plane at Perth's Jandakot Airport.

Emergency services were called to the airport in Perth's southern suburbs at 1:15pm after reports a small plane had crashed after an emergency landing on the runway.

The 73-year-old man, who was the sole occupant of the VH-POR De Havilland Chipmunk, was taken to Royal Perth Hospital with serious injuries.

He remains in a critical condition.

Aerial vision shows the plane crashed just outside the airport boundary, in the sand paddocks surrounding the runway.

The nose of the plane has been heavily damaged upon impact and the left wing visibly torn.

Pictures also show extensive damage to the cockpit and left side of the aircraft.

Fire crews and other personnel were on the scene.

The crash will be investigated by the Australian Transport Safety Bureau.
