A Jetstar flight heading from Tokyo to the Gold Coast has made an emergency landing on the Pacific island of Guam after the crew shut down one of the plane’s engines mid-flight.

Jetstar said the engine on flight JQ12 was shut down as a precaution after a warning light came on.

It said the plane landed safely.

The Australian Transport Safety Bureau said about 320 people were on board and the incident was now being investigated.

The airline told passengers via email and SMS that another aircraft was being sent to the island territory to pick them up.

That flight is expected to arrive on the Gold Coast on Monday morning.

In a statement, Jetstar apologised to passengers and said the plane was diverted to the closest airport.

“A flight from Narita [airport] to the Gold Coast was diverted this morning after the aircraft displayed an indicator message regarding oil pressure,” the airline said.

“Our experienced captain diverted the flight to the closest airport en route to the Gold Coast as a precaution, and it landed safely in Guam where it will be inspected by engineers.”
