The global Accessory Gearbox market size is predicted to grow from US$ 2250 million in 2025 to US$ 3608 million in 2032; it is expected to grow at a CAGR of 7.1% from 2026 to 2032.

In 2025, global accessory gearbox production reached approximately 27,100 units, with an average global market price of around US$85,000 per unit. Monthly production capacity is 52 units per line. Gross Profit Margin: 22%. The accessory gearbox industry chain begins with high-precision gear steel, bearings, shafts, and lubrication components, which are supplied by specialized aerospace-grade material manufacturers. These components are then machined, heat-treated, and assembled by gearbox producers who integrate mounting pads, gear trains, and lubrication systems. Downstream, the finished units are delivered to engine OEMs for installation in turbofan, turboshaft, APU, and industrial gas turbine platforms, with after-sales maintenance and overhaul forming an additional long-term service segment. The accessory gearbox market will continue to show resilient demand because it is tightly linked to aircraft engine deliveries, helicopter fleet renewal, and industrial turbine modernization. Although it is a niche product, its technical barriers, certification requirements, and long service cycles make it a stable and high-value segment with consistent long-term growth potential.
