Japan’s largest airline will replace 100 engines made by Rolls-Royce Holdings after problems forced flight cancellations this summer.
Reuters reported that cracks in the rear sections of ANA’s Boeing 787 Dreamliner engines led to vibrations.
The problems forced three ANA flights to return to their respective airports following takeoff in recent weeks, while the airline cancelled another 18 flights due to the issue through the end of August and could suspend more in coming weeks.
The airline, in an effort to temporarily fix the problem, will replace the turbine blades. Five engines were fully replaced as of Sept. 1, but replacement of all 100 engines in ANA's 50-jet Dreamliner fleet could take up to three years.
The company blamed the cracks on corrosion and fatigue cracking, some of which were allegedly caused by chemicals in the atmosphere. It is working with Rolls-Royce on a solution and is expected to ask the engine maker for compensation for its cancelled flights.
The issue, meanwhile, is only the latest setback for Boeing's embattled Dreamliner.
