Preliminary inquiries into an AirAsia X Airbus A330 incident on 25 June have confirmed a cause relating to its Rolls-Royce Trent 700 powerplants.

Rolls-Royce says it is working to "fully understand" the reason behind the failure which led the Kuala Lumpur-bound aircraft, operating flight D7237, to return to Perth.

But it stresses that the AirAsia X engine was being maintained under its TotalCare pact with the long-haul budget carrier.

"TotalCare is Rolls-Royce’s highest level of service and is available to any airline," says the manufacturer.

"Rolls-Royce would like to make it clear that there is no difference in the level of service provided between airlines, including low-cost carriers."

Investigators are still looking into the event involving an eight-year old A330-300 (9M-XXE) which had 359 passengers on board.
