An Airbus executive said Friday that Rolls-Royce has identified a faulty bearing box as the cause of the oil leak problem implicated in the midair disintegration of an engine on one of the world's largest airliners, an Australian newspaper reported.
Airbus Chief Operating Officer John Leahy said in Sydney that Rolls-Royce had at some point fixed the bearing box on newer versions of the Trent 900 engine, a model designed for the massive A380 superjumbo.
He said Rolls was now fixing it on older versions. The Herald Sun reported his comments on its website.
His comments did not address why Rolls-Royce had not fixed the bearing box in older versions of the engine.
Rolls-Royce declined to comment on his remarks.
The box in question contains the metal ball bearings that allow movement of the drive shaft that spins the turbines inside jet engines.
Investigators have said that leaking oil caused a fire in the engine of a Qantas A380 that heated metal parts and made the motor disintegrate over Indonesia last week, sending shrapnel into the wing and cutting vital safety systems before the jetliner landed safely in Singapore.
