ANA Holdings Inc., the world's biggest operator of Boeing Co.'s 787 Dreamliner jet, is canceling flights as it checks the Rolls-Royce Holdings PLC engines on its fleet for corrosion.
The airline, with a fleet of 50 Dreamliners, canceled nine flights using the aircraft Friday and may have to scrap more than 300 through the end of September, Takeo Kikuchi, a deputy senior vice president of engineering and maintenance, told reporters Thursday in Tokyo. ANA is replacing medium pressure turbine blades on the planes, Kikuchi said.
The 787-related flight cancellations are the largest for ANA since 2013, when Boeing and regulators grounded the global Dreamliner fleet while fixing a fire issue with the plane's lithium-ion battery. About 38 percent of the 787s in service are powered by Rolls-Royce's Trent 1000 turbines, while the rest are outfitted with General Electric Co. engines.
