mechanical issues in second engine11 Jun 2018 09:58
Rolls-Royce said it had identified mechanical problem in another type of aircraft engine and would have to carry out more inspections.
The company had already warned of durability issue affecting the Intermediate Pressure Compressor in Trent 1000 engines, known as Package C engines.
A similar issue had 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 company said.
The Package B standard had been in service since 2012 and consisted of 166 engines.
Rolls-Royce said the additional inspection requirements would incur some extra cost.
However, it said its understanding of the Package C service impact and 'mitigating actions we continue to take across the group' allowed it to stick to its fiscal 2018 free cash-flow guidance of �450m plus or minus �100m.
