Australian airline Qantas said today it was returning its grounded superjumbo fleet to the skies.

The airline's chief executive Alan Joyce said the decision to put the six Airbus A380s back into service followed the completion of engine safety checks since a massive failure over Indonesia earlier this month.

Mr Joyce said Qantas was now "completely comfortable now with the operation of the aircraft" and the first resumed flight would be at the weekend.

The scare prompted a global safety review of Rolls-Royce engines on 20 of the world's largest and newest jetliners across three airlines.

An investigation is still under way into the cause of the November 4. disintegration of the engine as the plane took off from Singapore.

Officials have indicated a fire caused by leaking oil was the likely cause.
