Rolls-Royce on Friday announced that a single faulty component caused the engine failure on the Trent 900-powered A380 Qantas flight QF32 that was forced to make an emergency landing last week.

The Sydney-bound flight made the dramatic emergency landing in Singapore due to what was announced as an “uncontained engine failure,” but after Rolls-Royce, the maker of the aircraft’s engine, investigated the incident through a series of engine checks, it determined that the issue is specific to the Trent 900, and the failure was confined to a specific component in the turbine area of the engine.

“This caused an oil fire, which led to the release of the intermediate pressure turbine disc,” the vehicle company said, adding that it continues to work with the investigating authorities for further analysis.

Rolls-Royce also said that it would be replacing the relevant module according to an agreed program.

“These measures, undertaken in collaboration with Airbus, our Trent 900 customers and the regulators have regrettably led to some reduction in aircraft availability. This program will enable our customers progressively to bring the whole fleet back into service.”
