ANA, Japan’s largest airline and the largest operator of Boeing 787 Dreamliners, plans to replace all 100 Rolls-Royce engines on its 50 787s following three engine failures this year, Reuters reported Wednesday.

In all three incidents since February, the airline found broken turbine parts that are attributed to corrosion and cracking of turbine blades. Rolls-Royce has said the problem is limited to ANA’s planes, which are used intensively on short domestic flights.

Rolls spokesman Richard Wray told Reuters the engine maker would swap out existing blades for new ones on ANA’s planes in the short term.

A new blade will be incorporated next year into engines going on new 787s, Wray said, adding that other airlines are managing the issue with “ongoing maintenance.”
