All Nippon Airways (ANA) has grounded multiple A321neo, Boeing 787-8, and 787-9 aircraft due to maintenance delays involving their engines. The ongoing issues with Rolls-Royce Trent 1000 engines on the 787 fleet and Pratt & Whitney GTF engines on the A321neos have led the airline to seek additional replacement engines to address the problem. Indeed, ANA grounds aircraft when necessary to ensure safety and reliability.
According to fleet data, ANA has grounded eleven A321neos as part of efforts to manage the maintenance backlog. Katsuya Goto, ANA’s executive vice president for the EMEA region, disclosed that the number of A321neo aircraft affected by Pratt & Whitney engine issues has decreased. However, he noted that engine inspection delays are expected to persist, potentially impacting operations for another two years. Therefore, ANA grounds aircraft to remain compliant with maintenance schedules.
In addition to the A321neo, ANA currently has four Boeing 787-8s and six 787-9s out of service. Although ANA has not confirmed that all these groundings result from engine issues, Goto emphasized the airline’s focus on sourcing replacement engines to minimize further disruption. It’s noteworthy that ANA grounds aircraft as part of its strategy to handle operational challenges.
Operational Adjustments
Despite these setbacks, Goto stated that the 787 groundings have had minimal impact on flight operations. ANA has utilized reserve aircraft and alternative models to maintain service on affected routes. This proactive approach has allowed the airline to mitigate the effects of the grounded planes and ensure continuity for its passengers. Consequently, ANA grounds aircraft strategically to optimize their operational efficiency.
ANA’s maintenance challenges highlight broader industry concerns over the availability of engine replacements and the delays in inspections. The airline’s commitment to resolving these problems remains strong as it works with manufacturers to address the maintenance backlog and return grounded aircraft to service.
