Progress has been made in discovering the cause of the engine failure which forced a Qantas Airbus A380 to make an emergency landing shortly after take off from Singapore.

Engine manufacturer Rolls-Royce said it was “now clear this incident is specific to the Trent 900 engine”.

The Australian carrier has grounded its fleet of six ‘superjumbo’ aircraft until at least the middle of the week while safety checks are carried out following the incident last Thursday.

Rolls-Royce said a series of checks and inspections has been agreed with Airbus, with operators of Trent 900-powered A380s and with the airworthiness authorities.

“These are being progressively completed which is allowing a resumption of operation of aircraft in full compliance with all safety standards,” the UK engine maker said.

“We are working in close co-operation with Airbus, our customers and the authorities, and as always safety remains our highest priority.”

Rolls-Royce is due to deliver a further update with its interim management statement on Friday (November 12).
