Rolls-Royce says that the uncontained engine failure on a Qantas Airbus A380 en route from Singapore to Sydney on November 4 “is specific to the Trent 900.”
“We can be certain that the separate Trent 1000 event which occurred in August 2010 on a test bed in Derby is unconnected,” Rolls-Royce said in a statement yesterday. “This incident happened during a development program with an engine operating outside normal parameters. We understand the cause and a solution has been implemented.”
The Trent 1000 powers the first four Boeing 787s, still engaged in flight testing.
Meanwhile, the company reports that it has made progress in understanding the cause of the failure of the Trent 900 on the Qantas A380. As a result, it said, it has agreed on a series of checks and inspections with Airbus, operators of the Trent 900-powered A380 and airworthiness authorities. “These are being progressively completed, which is allowing a resumption of operation of aircraft in full compliance with all safety standards,” said Rolls-Royce. “We are working in close cooperation with Airbus, our customers and the authorities, and as always safety remains our highest priority.”
The engine maker added that it would provide a further update on the investigation with its interim management statement on November 12.
