Qantas said it expected none. "I can confirm Rolls-Royce is arranging to supply some new engines from the production line to replace some engines removed from the serviced aircraft," an Airbus spokesman said, without saying which airlines would receive those engines. The Airbus A380 - the world's largest passenger aircraft with a list price of about $355 million - has been hit by safety concerns after a Rolls-Royce engine partly disintegrated mid-flight, forcing a fully laden Qantas plane to make an emergency landing on November 4.
