ANA, Japan’s largest airline, said on Wednesday it will replace all 100 Rolls-Royce engines on its fleet of fifty Boeing 787s following three engine failures this year caused by corrosion and cracking of turbine blades.
ANA currently has only five engines that need repairs, “but we will replace all the 100 engines for enhanced safety measures”, the company said, adding that it had already repaired three engines.
A Rolls-Royce spokesman said the engine manufacturer would swap out existing blades for new ones on ANA’s planes in the short term. The English company has started production of a new blade design that will be ready by the end f the year, he said.
The new blade will be used next year on engines going onto new 787s, Wray said, adding that other airlines are managing the issue with “ongoing maintenance”.
Rolls-Royce CEO Warrem East said on Tuesday that ANA’s problem is a manageable issue and added that ANA’s “intensive” use of the engines had accused the blades to wear more quickly than usual.
On Wednesday, ANA said four 787s remained grounded and that it had canceled 18 domestic flights due to the engine problem. The airline said it expected no further cancellations through mid-September. Beyond that its schedule had not been finalized.
The Rolls-Royce Trent 1000 engine, one of two engines for the Boeing 787 jetliner, costs about $20 million at list price. General Electric Co (GE.N) makes the other 787 engine, known as the GEnx.
