24 June 2026 - The International Air Transport Association (IATA), in collaboration with Emerton, today released a study examining bottlenecks in the maintenance, repair, and overhaul (MRO) of latest-generation single-aisle aircraft engines—namely LEAP engines from CFM, and Geared Turbofan (GTF) engines from Pratt & Whitney.
The study, Single Aisle Aircraft Engines MRO: Strategic Levers to Address Supply Chain Challenges, highlights how engine durability issues, spare parts shortages, limited spare engine availability, and constrained aftermarket access are disrupting airline operations. These pressures are creating costly operational challenges, including reduced engine time on wing, increased demand for engine shop visits, and more complex airline maintenance planning.
