TRENT 1000 SERVICE MANAGEMENT UPDATE

In April this year Rolls-Royce provided an update on the management of a durability issue affecting the Intermediate Pressure Compressor in a population of Trent 1000 engines, known as Package C engines. An update on the company's operational response to this issue was provided on May 30.

A similar Intermediate Pressure Compressor durability issue has now been identified on a small number of high life Package B engines. We have therefore agreed with Boeing and the relevant regulatory authorities to carry out a one-off inspection of our Trent 1000 Package B fleet, to further inform our understanding. The Package B standard has been in service since 2012 and consists of 166 engines.

While the consequences of the additional inspection requirements for Package B engines will incur some additional cost, this together with our latest understanding of the Package C service impact forecast and the mitigating actions we continue to take across the group, enable us to be confident that our FY18 guidance for Group FCF of around £450m +/- £100m remains unchanged.
