Trent 900 update

Friday, 12 November 2010

Rolls-Royce is now in a position to provide an update on its statement of 8 November concerning the engine failure on the Trent 900 powered A380 Qantas flight QF32 on 4 November 2010.

Immediately following this incident a regime of engine checks was introduced on the Trent 900s to understand the cause and to ensure safe operation. These have been conducted in parallel with a rigorous examination of all available evidence, including data from the damaged engine and its monitoring system, analysis of recovered material and interrogation of the fleet history.

These investigations have led Rolls-Royce to draw two key conclusions. First, as previously announced, the issue is specific to the Trent 900. Second, 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.

Rolls-Royce continues to work closely with the investigating authorities.

Our process of inspection will continue and will be supplemented by the replacement of the relevant module according to an agreed programme.

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

Safety continues to be Rolls-Royce’s highest priority.
