All Nippon Airways (ANA) will reduce its domestic and international network by thirty flights per day from January until late March, as Pratt & Whitney Geared Turbofans on 33 Airbus A320neo family need inspections and repairs. The reduction represents 3.6 percent of all of ANA’s daily flights and will have an impact on revenues of some ¥8.0 billion this financial year.
The Japanese carrier has 22 A321neo’s and eleven A320neo’s with GTFs that are subject to the inspections and repairs of the High-Pressure Turbine and High-Pressure Compressor disks, due to powder metal contamination. The aircraft were delivered between December 2016 and December 2021 with engines that have suspected parts that were produced between Q4 2015 and Q3 2015. Until engines receive new parts, existing parts will be subject to shorter cycles between inspections.
