The Jetstar Airbus 330-200, the same model as the Air France plane that crashed into the Atlantic Ocean, was about four hours into its flight from Osaka to Australia’s Gold Coast when the pilots noticed a small flame and smoke in the cockpit near the window, airline spokesman Simon Westaway said.
A pilot used a fire extinguisher to put out the fire, which did not spread to the cabin, he said.
The plane, which was carrying 190 passengers and 13 crew members, landed without incident at Guamairl International Airport. The passengers, mostly Japanese tourists, were expected to board another plane and finish their journey to Australia later on Thursday.
Qantas, which owns the budget carrier, was sending engineers to Guam to inspect the plane, and the Australian Transport Safety Bureau will lead an investigation into the cause of the fire, Mr Westaway said.
Noone was hurt during the incident.
The incident involves the same plane model as this month’s Air France disaster when all 228 on board an A330 flying from Brazil were killed after a mystery accident over the Atlantic.
