Aircraft Component MRO Market Size - By Component Type, By Aircraft Type, By Service Provider Type, and By End Use - Global Forecast, 2025 - 2034

 Aircraft Component MRO Market Size

The global aircraft component MRO market size was valued at USD 86.5 billion in 2024 and is estimated to grow at 4.7% CAGR from 2025 to 2034. The market is experiencing growth due to increasing air travel demand and rising global aircraft fleet.
 

The Trump administration's imposition of tariffs on imported aircraft components has significantly impacted the aircraft MRO market. Tariffs on parts from key suppliers in Canada, Mexico, and China have led to increased operational costs for U.S.-based MRO providers, as many aviation components previously benefited from zero tariffs under the 1979 Agreement on Trade in Civil Aircraft. This escalation in expenses has prompted airlines to reconsider maintenance strategies, with some deferring aircraft deliveries to avoid tariff-related costs. Additionally, suppliers are invoking "force majeure" clauses, potentially disrupting the supply chain and leading to delays in aircraft maintenance schedules.
 

After the pandemic aviation industry is accelerating with aircraft carriers strengthening their operational efficiency to compete in the market. This is leading to increase in maintenance of components to reduce flight downtime and optimize lifecycle of high value products. According to IATA, in 2025 total number of passengers expected to travel globally are estimated at 5,221 million.
 

Regulations from the aviation authorities for compliance with maintenance standards is another factor which drives the aircraft component MRO market. The regulatory standards ensure that strict certification and airworthiness requirements are met by regular inspections and overhauls. With technological advancements, the complexity of the modern aircrafts systems is increasing. The increase in complexity in turn requires advanced methods for the MRO of avionics and propulsion system. The safety incidents and component failures that require unplanned maintenance further contributes to the market growth. The commercial airline companies look forward to investing in advance compliance management systems to ensure appropriate documentation for the audits.
 

The players in the market should move towards digital transformation along with integration of artificial intelligence (AI) for predictive maintenance, real time monitoring and compliance tracking. Investing in additive manufacturing (3D printing) for certified parts can reduce turnaround times and costs, enhancing competitiveness. Strengthening partnerships with OEMs and airlines will help MRO providers expand service offerings and secure long-term contracts, particularly in high-growth regions like Asia-Pacific.
 

Aircraft Component MRO Market Trends

The aircraft component MRO industry is witnessing a rapid shift toward predictive maintenance, driven by advancements in AI, IoT, and big data analytics. Airlines and MRO providers are deploying sensors and real-time monitoring systems to track component health, reducing unscheduled downtime. According to IATA, predictive maintenance could save the aviation industry USD 3 billion annually by 2030.
 

Additive manufacturing (AM) is revolutionizing aircraft component repairs, enabling on-demand production of certified spare parts. Companies like GE Aviation and MTU Aero Engines are leveraging AM to reduce inventory costs and supply chain disruptions. This trend is particularly beneficial for legacy aircraft, where OEM parts may be obsolete. The ability to digitally warehouse component designs further enhance MRO efficiency.
 

Airlines are increasingly outsourcing MRO activities to third-party providers to reduce operational costs and focus on core business functions. This trend is fueled by the rising complexity of aircraft systems, which require specialized expertise and infrastructure. Independent MRO providers are expanding their capabilities to offer end-to-end solutions, including component repairs and line maintenance. The emergence of OEM-affiliated MRO networks is also gaining momentum, providing certified and reliable services. Low-cost carriers are leveraging outsourced MRO to maintain lean operations. This shift is creating lucrative opportunities for global MRO players, especially in cost-sensitive markets.
 

Original Equipment Manufacturers (OEMs) are expanding their MRO footprints to capture a larger share of the aftermarket services segment. Boeing’s Aviall and Airbus’ Satair are leading examples, offering end-to-end component support with digital tracking. This shift is driven by airlines seeking OEM-certified repairs to maintain warranty compliance and resale value. Additionally, partnerships between MRO providers and OEMs, such as ST Aerospace’s collaboration with Pratt & Whitney are enhancing component lifecycle management. The trend is strongest in engine and landing gear MRO, where technical complexity demands OEM expertise.
