    ANA To Replace Engine Turbine Blades On 787s


    Japanese airline group All Nippon Airways (ANA) has confirmed it will replace turbine blades on the Rolls-Royce Trent 1000 engines powering its fleet of 50 787 aircraft after identifying problems related to corrosion and cracking.

    The carrier confirmed on Wednesday (August 31) to Reuters that the process for fitting the 787s with engines equipped with new blades could take up to three years to complete.

    ANA said just five of the engines are in need of repairs at present, but it decided to repair the entire fleet of 100 Trent 1000s as a safety measure.

    It follows three engine failures in 2016 related to the blades, while 18 domestic flights were cancelled by ANA last week as a result of engine issues.

    Air New Zealand, another carrier operating Trent 1000-powered 787s, said it has put “proactive systems” in place across its fleet of seven of the aircraft to any potential monitor turbine problems.
