All Nippon Airways will cancel 378 domestic flights operated by Boeing 787s during August to accommodate mandatory inspections on their Rolls-Royce Trent 1000 engines.
The planned cancellations are down significantly from the 619 reported during July, which were triggered by a Japan Civil Aviation Bureau move to extend the scope of inspections on ‘Package C’ Trent 1000s to include ‘Package B’ engines.
ANA adds that it owns 66 Package C and 70 Package B Trent 1000 engines. Flight Fleets Analyzer shows that the engines power its fleet of 36 787-8s and 28 787-9s.
“Safety is always our top priority for our customers, and we consider these cancellations unavoidable to maintain our highest safety standard,” says the Star Alliance carrier.
The inspections have been triggered by durability issues with intermediate compressor blades in both variants of the Trent 1000 engine. Those have been cited in recent investigations into engine failure incidents on 787s operated by Air New Zealand and Scoot.
A number of other Trent 1000 operators have also been affected by the increased inspection cycle on the engines, with Virgin Atlantic, LATAM Airlines, and Air New Zealand leasing in other aircraft to cover downtime on their 787 fleets.
