The other engine for the A380 is the Alliance GP7200 built by an alliance of GE and PW. GE builds the core, and PW builds the fans.
Quantas not Airbus or Rolls Royce required higher safety margins for returning to the air.
“Qantas had imposed conditions and restrictions over and above what Rolls-Royce, Airbus and the Civil Aviation Safety Authority demanded for A380s resuming service.”
Rolls Royce is facing large claims.
“According to Qantas, Rolls Royce will have to replace forty of these defective reactors which power the world’s fleet of Airbus A380. For its part, Rolls Royce has assured its customers they have identified the problem and pledged to change a defective element of the turbine.
Nevertheless, this case looks expensive for Rolls Royce, because airlines could turn against the engine and require compensation. Industry analysts suggest the amount is already running into hundreds of millions of dollars.”
Airbus comes with two engine options: Rolls-Royce’s Trent 900 and an alternative engine dubbed “Engine Alliance” designed by General Electric Co. and Pratt & Whitney. Following the failure in Trent 900, many customers waiting on orders such as the UAE and China Southern Airlines Co. are considering switching to the alternative Engine Alliance instead.
Air France is already flying its A380s with alternative Engine Alliance engines and has had no reported issues so far.
