SYDNEY - SINGAPORE Airlines resumed flying its A380 fleet on Friday, lifting a grounding order imposed after a Qantas A380 engine failed inflight, forcing the aircraft to make an emergency landing.

The Qantas engine failure, which forced the plane back to Singapore airport on Thursday, marks the biggest incident with the A380, the world's largest passenger plane which has been in service only since 2007. Qantas' A380 fleet remains grounded.

SIA said it had checked and cleared its entire fleet of 11 Airbus A380 aircraft for service, said a spokesman for the airline in Australia.

All 11 of Singapore Airlines' A380 aircraft had been inspected and were found be safe, Susan Bredow told Reuters.

'They have all been inspected in accordance with the requirements of Airbus and Rolls-Royce. That was done overnight and everyone is satisfied the aircraft are serviceable and will be back on their scheduled routes as soon as possible,' she said.

Australia's Qantas Airways on Thursday grounded its six A380 aircraft, pending the outcome of investigations into the reasons for the failure of one of its four Rolls-Royce engines which appeared to break apart during the Sydney-bound flight.
