All Nippon Airways (ANA) has announced a third round of Boeing 787 domestic flight cancellations to allow for checks on the type’s Rolls-Royce Trent 1000 engines.
In its latest announcement on the issue, ANA says it will cancel 330 additional domestic 787 flights from 23 July to 31 July.
On 4 July, the carrier said it would cancel 113 domestic 787 services between 6-12 July. On 9 July, it said that it would cancel an additional 176 domestic 787 services up to 22 July.
The latest round of cancellations brings the total number of cancellations to 619 between 6 July and 31 July. FlightGlobal Schedules shows that the carrier had intended to operate 1,346 domestic 787 flights during this period.
“Over the last two years, we have been working very closely with Rolls Royce and the regulatory authorities,” it says. “However, due to the additional mandatory inspections that were announced by the Japan Civil Aviation Bureau (JCAB) on June 14, 2018, which involve twice as many engines to be inspected, we are cancelling a limited number of flights.”
The inspections affect the carrier’s 66 Trent 1000 Package C powerplants, and 70 Trent 1000 Package Bs. The Package B engines were added to the scope of mandatory inspections in June.
Flight Fleets Analyzer shows that ANA operates 64 787s comprising 36 787-8s and 28 787-9s. ANA is the largest operator of Boeing 787s powered by the Rolls-Royce Trent 1000 Package B engines, which have been newly included in the UK manufacturer’s inspection regime to deal with durability issues.
Corrected: A previous version of this story incorrectly stated the number of cancellations between 23-31 July.
