Commercial Aviation Faces Disruptions Amid Engine Repair Delays

The International Air Transport Association (IATA) has released a report highlighting the significant disruptions caused by engine maintenance, repair, and overhaul (MRO) bottlenecks in commercial aviation. The study, conducted in collaboration with Emerton, focuses on the latest-generation single-aisle aircraft engines, including LEAP engines from CFM International and Geared Turbofan (GTF) engines from Pratt & Whitney. IATA’s Director General, Willie Walsh, emphasizes the need for better access to spare parts, more approved repair options, and fair access to MRO capacity to address the issue. The report was published on the IATA website, as reported by AeroTime.
