Aircraft Gears Market - Global Industry Size, Share, Trends, Opportunity, and Forecast, 2021-2031

The Global Aircraft Gears Market is projected to expand from USD 369.19 Million in 2025 to USD 509.34 Million by 2031, reflecting a CAGR of 5.51%. These gears are precision mechanical components essential for transmitting torque and regulating speed between engine shafts and various actuation systems or accessory drives in aerospace platforms. The market's growth is largely driven by the rising demand for new commercial aircraft and increased military spending, both of which require strong supply chains for original equipment manufacturing and aftermarket replacements. Data from the General Aviation Manufacturers Association (GAMA) highlights this upward trend, indicating that the preliminary value of aircraft deliveries in 2024 reached $31.2 billion, a 13.3% increase over the previous year.

Despite these favorable conditions, market expansion faces significant hurdles due to supply chain fragility. The ongoing scarcity of high-quality raw materials and skilled labor continues to interrupt production schedules, creating bottlenecks that delay component deliveries. These disruptions also drive up manufacturing costs for gear suppliers worldwide, posing a substantial challenge to meeting the industry's growing requirements.

Market Drivers

The expansion of global air passenger traffic is a primary catalyst for fleet growth, significantly boosting the demand for transmission components within the commercial aviation sector. As airlines work to accommodate the resurgence in travel, the procurement of new aircraft has accelerated, necessitating reliable production pipelines for actuation gears and engine accessory drives. According to the International Air Transport Association's full-year analysis released in January 2025, global traffic rose by 10.4% in 2024 compared to the prior year. This volume increase places immense pressure on suppliers; for instance, Airbus reported in its January 2025 annual update that it delivered 766 commercial aircraft, ensuring sustained demand for both initial gear installations and future aftermarket support.

Simultaneously, rising defense budgets and military modernization programs are driving the need for specialized, high-strength gear systems. Geopolitical instability is prompting governments to invest heavily in next-generation fighter jets and rotorcraft, which depend on precision-engineered gearboxes for propulsion and lift. This trend is reflected in the financial results of major defense contractors; GE Aerospace reported in January 2025 that orders in its Defense & Propulsion Technologies segment grew by 22% year-over-year in the fourth quarter of 2024. Such capital investments are crucial for developing the durable gear solutions required to maintain operational readiness in advanced military platforms.

Market Challenges

Supply chain fragility, particularly the shortage of skilled labor and high-grade raw materials, stands as a major obstacle to the growth of the Global Aircraft Gears Market. Manufacturing aerospace-grade gears demands specialized titanium and alloy steels, along with a workforce capable of executing precision machining to micron-level tolerances. When these critical inputs are restricted, lead times for manufacturing extend considerably, making it difficult for suppliers to meet the aggressive delivery schedules set by airframe and engine manufacturers. This disruption creates a production ceiling that effectively caps revenue growth, as manufacturers are physically unable to produce enough components to satisfy the surging demand for new aircraft.

The severity of these supply constraints is highlighted by the growing gap between aircraft demand and actual production rates. In 2024, the International Air Transport Association (IATA) reported that the global backlog of unfulfilled commercial aircraft orders reached a record high of approximately 17,000 units. This accumulating backlog suggests that critical component suppliers are struggling to scale their output efficiently. Consequently, the gear market is prevented from fully capitalizing on the current aerospace upcycle, with revenue realization delayed indefinitely until production capacities can align with the high volume of orders.

Market Trends

The aerospace industry is undergoing a significant structural shift toward the widespread adoption of Geared Turbofan propulsion architectures to meet strict fuel efficiency goals. Unlike traditional direct-drive engines, this design employs a high-power planetary reduction gearbox to decouple the engine fan from the low-pressure compressor, allowing each module to operate at its optimal efficiency speed. This architectural evolution increases the content value per engine for gear manufacturers, as the gearbox becomes a critical, life-limited component requiring precision engineering. The financial impact of this transition is evident; MTU Aero Engines reported in October 2024 that organic revenue in its commercial series segment rose by over 20% year-over-year in the third quarter, driven largely by strong demand for Geared Turbofan programs.

Concurrently, the deployment of smart sensors for real-time gearbox health monitoring is revolutionizing aftermarket sustainment strategies. Operators are increasingly embedding acoustic, thermal, and vibration sensors directly into transmission housings to shift from fixed-interval overhauls to predictive maintenance, thereby extending component lifecycles and reducing unplanned downtime. This digitalization is fueling growth within the services segment as airlines prefer data-driven support contracts over traditional repair models. This trend is supported by Safran's October 2024 revenue report, which noted a 20.5% increase in civil aftermarket revenue for the third quarter, reflecting intensified demand for spares and rate-per-flight-hour service agreements.
