All Nippon Airways Co. said Thursday it will repair some of its Boeing 787 fleet due to engine defects, a move that would affect the major Japanese carrier's flight services with some canceled flights.
ANA has been investigating a slew of cases in which its twin-engine B-787s had to turn back after detection of abnormalities in their engines. The carrier's 50 B-787s are all equipped with engines made by Rolls-Royce.
Japan Airlines Co., the other major Japanese airline, also has a fleet of B-787s but they are not affected as their engines are made by General Electric.
An ANA flight to Fukuoka was forced to return to Tokyo's Haneda airport in the morning after an indicator in the B-787's cockpit showed abnormalities in its left engine, prompting the transportation ministry to ask the carrier to report on whether the incident was associated with the previous trouble.
It is not the first time B-787s have faced a mechanical problem. In January 2013, smoke and fire were found coming out of the batteries on the aircraft in the ANA and JAL fleets, prompting U.S. and Japanese aviation authorities to temporarily ground the aircraft.
The two carriers were only able to resume regular flight services using the aircraft in June after Boeing made changes to fix the problem.
