ANA Holdings Inc. said Thursday it will call off 330 domestic flights between July 23 and 31 to inspect Rolls-Royce engines on Boeing 787 aircraft, bringing the total number of such cancellations since early July to 619.

The cancellations of flights to and from 13 airports in Japan is expected to affect about 58,000 passengers, ANA said.

ANA has been inspecting the Rolls-Royce engines under instruction from the Japanese transport ministry, as an apparent design flaw might cause cracks in a rotor blade.

The company plans to announce cancellations for August next Tuesday but the number of such cancellations is likely to drop to about 10 to 20 per day compared with 15 to 40 this month, according to ANA.
