The single-engine, four-seater aircraft came down at the airport around 3.40pm, and flipped on impact, trapping the male pilot aged in his 60s.
Emergency crews rushed to the scene with firies making the area safe after a large amount of fuel spilled from the aircraft, while rescuers freed the pilot.
A nearby worker said he heard a huge “bang” and when he went outside, could see the plane upside down.
NSW Ambulance Inspector Craig Watkins said it was a potentially dangerous scene, with fuel leaking from the crashed plane and one person on board.
“Once the scene was made safe by Fire and Rescue NSW, paramedics accessed the patient and began treating him for multiple injuries when he went into cardiac arrest,” Supt Watkins said.
“Paramedics performed CPR and succeeded in restarting the man’s heart before taking him to hospital.”
He was taken to hospital in a critical condition, suffering arm, chest, leg and spinal injuries.
It is believed the plane had travelled from the Gold Coast.
The Australian Transport Safety Bureau is investigating the cause of the crash.
