Sydney: A Qantas Airways flight returned to Bangkok on Friday after pilots were forced to shut down one of the aircraft`s engines, the latest in a string of incidents involving Rolls-Royce engines.
Qantas said one of the Boeing 747`s four engines experienced "high vibration and temperature" shortly after takeoff.
"The plane landed an hour later in Bangkok in a standard landing. This was not an emergency and has no relation whatsoever with Rolls Royce engine incident in an A380 last year," a Qantas spokesman said.
The flight was bound for London.
An uncontained engine failure or blow-out in a Rolls-Royce Trent 900 engine forced a Qantas Airbus A380 to make an emergency landing in Singapore last November and prompted the temporary grounding of the Australian carrier`s A380 fleet.
A Cathay Pacific aircraft made an emergency landing in Singapore with an engine problem on Monday. Rolls-Royce said it would support the investigation into that incident.
