Global Aircraft Gearbox Market size was valued at USD 3.64 Billion in 2024 and is poised to grow from USD 3.9 Billion in 2025 to USD 6.75 Billion by 2033, growing at a CAGR of 7.1% during the forecast period (2026–2033).
The global aircraft gearbox market growth is driven rapidly due to the rebound in air travel and the expansion of aircraft fleets. Both passenger and cargo traffic growth directly contribute to new aircraft growth and aftermarket gearbox MRO (Maintenance, Repair, Overhaul) workloads. As environmental regulations impose compliance in emissions and mandate fuel efficiency improvements from manufacturers, they are looking to use more lightweight and advanced material & designs in gearboxes and design gearboxes that can enhance aircraft performance whilst not imposing a negative impact on the environment. Technological developments such as additive manufacturing, use of smart sensors for predictive maintenance, and continued advancement in IoT & AI are making gearboxes more reliable and efficient and helping to reduce costs. The military sector is also driving demand as increased defense budgets create further demand for more modern helicopters and tactical aircraft. Meanwhile, a recent metamorphosis to being more electric or hybrid into the future also creates opportunities for new gearbox architectures which can accommodate higher power density and different transmission requirements.
How Are Manufacturers Integrating IoT into Gearbox Maintenance?
The incorporation of IoT technologies in the aviation industry is redefining how aircraft gearboxes and full propulsion systems are monitored, controlled, and maintained. IoT-enabled sensors installed throughout aircraft engines and gearboxes constantly collect vital data, such as temperature, vibration, pressure, and wear. The data are transferred in real-time to shore-based control centers to help engineers evaluate the health of critical components and proactively predict failures ahead of flight operations. IoT systems provide predictive maintenance opportunities, by enabling airlines to schedule repairs on their components based on actual conditions vs arbitrary timelines; it also provides the airline with the opportunity to reduce unplanned downtime and maintenance costs, allowing the airline to detect faults before they develop into something worse. The Rolls-Royce Engine Health Monitoring system and the connected systems found in the Boeing 787 Dreamliner are good examples of how real-time IoT data can replace current situational awareness and knowledge, offering the airline a way to enable preventive maintenance and operational efficiency.

Why are OEM Channels Most Preferred in the Aircraft Gearbox Sector?
The OEM channel will continue to dominate the aircraft gearbox sector. The OEM's share is derived from them directly manufacturing and building aircraft, where they have the opportunity to integrate gearboxes into their assembly lines and offer bespoke, compliant solutions for government mandated safety controls. Their long-term contract structure and established relationships with airline and operator clients deliver a constant stream of large orders, which solidifies OEMs as the backbone of the gearbox supply chain, and a key partner for equipment manufacturers. Additionally, the OEM equipment is packaged into a comprehensive service package that includes after-market support, entrenching their dominant position as the most stable and responsible market segment.
The aftermarket segment is the fastest growing segment by sales channel because of the aging global aircraft fleet and need for Aviation Maintenance, Repair and Overhaul (MRO). Gearboxes are an emerging maintenance focus and legally mandated for safety which maintains the aviation sector's dual focus: operational and safety compliance. Therefore, scheduled inspections, emergency replacement of components, and potential upgrades create a continuing need in the aftermarket for aircraft gearbox replacements, even when new aircraft production is reduced.
Why do Engine Applications Dominate the Aircraft Gearbox Market?
The engine application is the largest application segment in the aircraft gearbox industry, as gearboxes are required to transfer engine power to propellers, rotors, or other auxiliary systems. These gearboxes provide significant enhancement to engine performance and fuel efficiency, while also ensuring reliable propulsion units when used in both commercial and military as well as general aviation. Gearbox applications play an important role in air vehicle design in both legacy and new developments in numerous engine configurations including turbofan, turboprop, turbojet, and turboshaft engines. Engine gearboxes are critical in legacy and new air worthiness aircraft designs and are the largest revenue segment in the application segment, driven by airline's desires to operate more efficiently and meet regulatory requirements.
The hybrid-electric and electric vertical takeoff and landing (eVTOL) applications is the fastest application segment, driven by the push for sustainability and the aviation sector's desire for electrification. As manufacturers embark on developing next-generation aircraft with hybrid-electric or fully electric propulsion systems, these manufacturers need fresh gearbox solutions, so they can develop gearboxes that can respond to unique power profiles and transmission requirements of hybrid or fully electric propulsion systems. This transition will provide opportunities for lightweight, compact, and efficient gearboxes, specifically in urban air mobility (UAM) and advanced air mobility (AAM) applications.
