Aviation MRO - Engine Overhaul - CFM56: Market Size & Forecast 2026

The global CFM56 engine overhaul market sits at approximately USD 12.5 billion in 2025, held in a structurally tight equilibrium between an installed base of over 23,000 engines still in commercial service, supply-chain constraints that keep lead times extended, and an MRO ecosystem consolidating around a shrinking pool of certified providers. The 4.2% CAGR through 2032 reflects the maturity of the narrowbody replacement cycle offset by structural aftermarket stickiness and parts-price inflation from the OEM. The CFM56-7B variant, powering the Boeing 737NG fleet, remains the dominant service event, representing roughly 55% of all shop visits. Over 12,650 CFM56-7B engines remain active across the global narrowbody parc. The CFM56-5B variant, on Airbus A320ceo, has recovered to parity in demand intensity following the pandemic trough, as operators extend airframe lives amid delivery delays
