Market Research Future values the United States aircraft maintenance, repair and overhaul market at $55.76 billion for 2025, up from $51.69 billion in 2024. The firm projects the market reaching $110.56 billion by 2035, a compound annual growth rate of 7.16 percent across the 2025 to 2035 forecast window. The chart plots that spending curve year by year.

The report segments US spending four ways by type: engine, line, airframe and other components. Line maintenance holds the largest share, reflecting routine turnaround work performed between flights. Engine maintenance is identified as the fastest growing segment, which tracks with rising shop visit volume and the cost weight of hot section work. By application, the market splits between commercial aircraft and military aircraft, with commercial holding the larger share while military work expands at a faster clip.

The report lists nine US companies as major participants: AAR Corp, General Electric, Honeywell International, Northrop Grumman, Raytheon Technologies, Boeing, L3Harris Technologies, Spirit AeroSystems and Delta TechOps. That roster spans independent repair stations, engine and component manufacturers, defense sustainment contractors and airline owned maintenance divisions.

Named growth drivers include technological advances in maintenance practice, a growing fleet of aging aircraft, and regulatory compliance and safety standards that require documented work. The analysis also points to predictive maintenance and data analytics reducing aircraft downtime, and to sustainability requirements shaping material and process choices at repair facilities.
