The Air Transport USM Market is evolving rapidly as airlines, MRO providers, and OEMs adapt to shifting fleet dynamics and cost pressures. Used Serviceable Material (USM) plays a central role in helping aviation stakeholders reduce maintenance costs, mitigate supply chain bottlenecks, and extend aircraft lifecycles — benefits that are particularly critical in a competitive post-pandemic environment.

According to recent projections, the Air Transport USM Market is expected to grow from 97 USD Billion in 2025 to 150 USD Billion by 2035. The Air Transport USM Market CAGR (growth rate) is expected to be around 4.5% during the forecast period (2025 - 2035).. 

Cost Efficiency as a Market Driver

One of the most significant drivers of USM market growth is cost reduction. Airlines face rising maintenance, repair, and overhaul (MRO) expenses — particularly for high-value components such as engines and avionics — and USM offers a financially viable alternative to expensive new parts. By using certified used parts that meet regulatory standards, operators can decrease operating costs while ensuring aircraft remain compliant and airworthy. 

Aging Fleets and Component Demand

The global aircraft fleet is aging, especially in regions where new aircraft deliveries have been delayed due to supply chain constraints and production backlogs. With slower turnover, carriers increasingly rely on used serviceable materials to maintain older airframes and systems, driving extended demand for USM components. This trend is particularly noteworthy in narrowbody fleets that constitute the backbone of short- and mid-haul operations. 

Expanding MRO Activities

Global MRO activities — driven by both scheduled heavy checks and unscheduled repairs — are central to USM adoption. As airlines schedule more frequent maintenance checks to ensure safety and reliability, they tap into the USM inventory, especially for engine and airframe parts that demand high turnover. This widespread utilization reinforces the importance of USM as a strategic maintenance resource. 

Regional Market Trends

The regional landscape reveals distinct growth patterns: North America retains the largest share due to its mature aviation infrastructure, high aircraft utilization, and dense teardown operations. European carriers and MRO hubs also contribute significantly to USM consumption due to fleet diversity and robust maintenance networks. Meanwhile, the Asia-Pacific region is emerging as one of the fastest-growing markets — driven by expanding commercial aviation fleets, rising air travel demand, and improvements in local MRO capacity. 

Technological Advancements and Digitalization

Digitalization is a major trend transforming the Air Transport USM Market. USM suppliers and MRO providers increasingly use AI-driven inventory management systems, predictive analytics for demand forecasting, and blockchain or RFID technologies to enhance component traceability and compliance. These innovations improve part quality assurance and streamline supply chain operations by reducing lead times, enhancing transparency, and strengthening confidence among buyers and regulators. 

The adoption of digital tracking tools allows airlines and MRO partners to retrieve detailed maintenance histories, trace part provenance, and improve logistical efficiencies — essential capabilities in a market where quality and certification matter as much as cost. 

Sustainability and Circular Economy Initiatives

Another emerging trend propelling market growth is sustainability. Reusing and repurposing serviceable aircraft material reduces waste associated with new component manufacturing and aligns with broader aviation environmental goals. Many carriers are incorporating USM strategies into their long-term sustainability plans by reducing material waste and extending asset lifecycles — a structural advantage that supports both cost efficiency and environmental stewardship. 

Strategic Alliances and Competitive Landscape

The competitive landscape of the Air Transport USM Market includes both independent traders and larger MRO/OEM partners. Key players such as AAR Corp., AerSale Inc., GA Telesis LLC, Delta TechOps, Lufthansa Technik AG, and others are expanding their USM offerings through teardown facilities, global distribution networks, and enhanced certification programs. OEM-linked programs — in which manufacturers incorporate USM into maintenance contracts — are also gaining prominence, boosting market presence and acceptance among carriers. 

Future Forecast

With steady growth anticipated through 2034, the Air Transport USM Market is set to become an increasingly strategic pillar in the aviation aftermarket. Operators, MROs, and suppliers alike are expected to invest further in digital tools, expand teardown capacities, and optimize global distribution networks to capitalize on growth opportunities.
