Engine maintenance issues have forced ANA - All Nippon Airways (NH, Tokyo Haneda) to ground multiple A321-200Ns, B787-8s, and B787-9s. Maintenance backlogs for the Rolls-Royce Trent 1000s used on its B787s and Pratt & Whitney GTF engines used on its A321neo jets are requiring the carrier to ground aircraft while it scrambles to source additional engines.
According to the ch-aviation fleets module, eleven of ANA's A321neo are out of service, namely JA131A (msn 7839), JA133A (msn 8095), JA134A (msn 8187), JA135A (msn 8212), JA136A (msn 8229), JA138A (msn 8349), JA141A (msn 8626), JA142A (msn 9589), JA145A (msn 10531), JA151A (msn 10470), and JA152A (msn 10517).
ANA's executive vice president for the EMEA region, Katsuya Goto, recently told Aviation Week that the number of A321neo grounded due to Pratt & Whitney issues had decreased but that the engine inspection delays will continue to hamper the airline for another two years.
There are also four B787-8s (JA805A (msn 34514), JA808A (msn 34490), JA832A (msn 42249), and JA838A (msn 34528)) and six B787-9s (JA877A (msn 43871), JA882A (msn 43872), JA884A (msn 34523), JA890A (msn 34500), JA898A (msn 40752), and JA921A (msn 43865)) out-of-service, although ANA has not confirmed that all of the groundings are because of the engine issues. However, Goto said that the carrier was trying to source as many replacement engines as possible. He said the B787 groundings are having minimal impact on operations as ANA is drawing on reserve aircraft and other aircraft types to operate flights on some routes.
