Rolls-Royce pulled 53 engines after blowout


Engine maker Rolls-Royce removed 53 of its Trent 900 engines from service following last year’s engine blowout on a Qantas A380, according to a report into the incident released.

The Australian Transport Safety Bureau’s (ATSB) interim report into the incident said the engines were removed due to concerns over the thickness of oil feed pipes.

The report said the engine’s intermediate pressure turbine failed because of a manufacturing fault in an oil feed pipe, which caused it to crack, leading to an internal oil fire, Reuters reports.

The majority of engines were removed because Rolls was “unable to establish whether these oil feed tubes had been manufactured to specification” and because of “a lack of measurement records” for the pipes, said the report.
“We fully support the ATSB’s ongoing investigation and are actively addressing the points raised,” a Rolls-Royce spokesperson said.
“As the investigation is still ongoing it would be inappropriate for us to comment further at this stage.”

One of Rolls’ Trent 900 engine failed mid-flight on a Qantas Airbus A380 last November in one of the most serious incidents for the world’s largest passenger plane in its three years of commercial flight.

Rolls previously said it had removed several engines to replace the faulty component.

The ATSB said its investigation was still ongoing and that its report would likely be complete by May 2012.
