#Japan's ANA finds problem with Boeing 787 Rolls-Royce engines, cancels some flights

ANA needs to replace damaged compressor blades in the Rolls-Royce engines powering its Boeing 787s, it said Thursday, forcing it to cancel some Dreamliner flights over the coming weeks. The carrier said that under certain flying conditions the compressor blades in the engine's interior showed corrosion. ANA will cancel 9 domestic 787 flights Friday, with other cancellations likely in the coming weeks. ANA's Dreamliners are powered by Rolls-Royce Trent 1000 engines. The airline is the biggest operator of the 787 with some 49 aircraft, or around a tenth of the global fleet. Rolls-Royce did not say whether the problem had been found in 787 engines on aircraft operated by other airlines, but when asked about any requirement to take additional action a spokesman said the issue was limited to a small proportion of the ANA fleet. <br/>
