All Nippon Airways will cancel 113 domestic flights of Boeing 787s between 6-12 July in order to carry out additional checks on Rolls-Royce Trent 1000 engines.
FlightGlobal Schedules shows that ANA plans to operate 316 domestic services with 787-8s and -9s during the period, meaning that the engine checks will cancel over one third of ANA’s 787 domestic flights.
Against ANA’s total of 3,241 domestic services, however, the 787 cancellations are negligible.
“Over the last two years, we have been working very closely with Rolls Royce and the regulatory authorities,” says ANA.
“However, due to the additional mandatory inspections that were announced by the Japan Civil Aviation Bureau on [14 June], which involve twice as many engines to be inspected, we are cancelling a limited number of flights.”
The new inspections relate to Trent 1000 Package B engines, says ANA.
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.
Half of that fleet is equipped with Package B engines, while the balance uses either the Package C variant or Rolls-Royce's latest standard model for the 787, the Trent 1000-TEN.
Rolls-Royce disclosed in early June that intermediate compressor blade cracking had been found on a “small number" of "high-life” Package B engines; previous statements and inspection requirements had related to the later Package C variant.
