The global Air Transport Used Serviceable Material (USM) Market was valued at USD 8.55 billion in 2025 and is projected to grow from USD 8.95 billion in 2026 to USD 12.93 billion by 2034, registering a CAGR of 4.7% during the forecast period. Market growth is being driven by increasing demand for cost-efficient aircraft maintenance solutions, rising commercial aircraft fleets, and the aviation industry's growing focus on sustainability and lifecycle optimization. In 2025, North America dominated the global market with a 34.85% share, supported by a mature aviation ecosystem and extensive maintenance infrastructure.
The aviation industry continues to prioritize operational efficiency and maintenance cost reduction, creating strong demand for used serviceable materials (USM). USM refers to previously utilized aircraft parts that have been inspected, repaired, certified, and approved for continued operation.
Airlines and maintenance providers increasingly adopt USM components as an alternative to purchasing new parts due to lower acquisition costs and shorter lead times. These solutions support fleet availability while helping operators manage maintenance budgets more effectively.
As aircraft operators continue focusing on cost optimization and maximizing asset utilization, demand for certified serviceable materials is expected to increase steadily.
The continued expansion of global air travel and fleet modernization programs is contributing significantly to the growth of the air transport USM market. Airlines are maintaining larger fleets while extending aircraft service life, increasing demand for maintenance, repair, and overhaul (MRO) services.
Aircraft retirements are also creating additional opportunities for component harvesting and redistribution through the USM supply chain. Recovered components such as engines, landing gear systems, avionics, and cabin equipment provide operators with economically viable replacement options.
Increasing fleet utilization and maintenance cycles are expected to strengthen long-term market demand.
Environmental sustainability has become an important factor influencing the aviation sector. Airlines and aviation service providers are increasingly adopting circular economy practices to reduce waste and improve resource efficiency.
Used serviceable materials contribute to sustainability goals by extending component life cycles and reducing the environmental impact associated with manufacturing new aircraft parts. The reuse and recertification of aviation components also support emissions reduction initiatives across the broader aerospace industry.
Growing industry emphasis on sustainable operations is expected to further encourage USM adoption globally.
Advancements in digital maintenance technologies and asset management systems are enhancing confidence in USM adoption. Modern inventory tracking platforms, predictive maintenance tools, and component lifecycle analytics are improving traceability and operational reliability.
Digital records, maintenance documentation systems, and enhanced inspection technologies allow operators to verify part history and ensure compliance with aviation standards.
The integration of data-driven maintenance practices is helping airlines optimize inventory planning and reduce aircraft downtime.
North America accounted for 34.85% of global air transport USM market revenue in 2025, supported by strong airline networks, established aircraft maintenance infrastructure, and a large installed aircraft base.
The region benefits from advanced MRO capabilities and the presence of leading aviation service providers and component suppliers.
