A plane has made an emergency landing at Perth Airport after a suspected engine fire erupted shortly after take-off.

The Cobham Aviation flight landed safely after the mid-air incident on Tuesday, a Perth Airport spokeswoman confirmed.

Witnesses have reported seeing the flames coming from the right engine.

The Perth Airport website shows that a Cobham Aviation flight was scheduled to depart at 10.45am for Barrow Island.

Pictures have emerged on social media of a plane with an engine appearing to be on fire, but it has not been confirmed as the plane involved in the emergency.

The aircraft is currently being assessed at the airport.

Cobham operates aircraft on behalf of Qantas regional subsidiary QantasLink.

A spokesman for the regional carrier said a statement would be issued later on Tuesday.
