Landing Gears Undercarriage Market: Market Size & Forecast 2026

The Landing Gears Undercarriage Market covers structural and mechanical systems that enable aircraft, commercial vehicles, and heavy machinery to taxi, land, and operate safely on ground surfaces. The market was valued at approximately USD 6.8 billion in 2025, with projections varying by segment scope and methodology across industry estimates. The broader undercarriage components space, which includes track systems for earthmoving equipment, has been separately estimated at over USD 7.85 billion, reflecting the overlap and breadth of the category.

• •Market valued at ~USD 6.8B in 2025, with long-term projections reaching between USD 8.3B and USD 9.4B depending on segment scope and time horizon
• •Encompasses commercial aviation, military, regional aircraft, and heavy equipment undercarriage systems and components
• •Main landing gears segment alone was valued at USD 5.68B in 2025 and is tracked separately in dedicated market analyses

The single largest driver is the robust commercial aircraft order backlog at Airbus and Boeing, which translates into sustained demand for new landing gear assemblies over more than a decade of planned deliveries. Fleet modernization programs are pushing airlines to retire older aircraft, creating replacement demand for newer-generation landing gear with improved materials and braking systems. Infrastructure spending and construction activity in Asia-Pacific and the Middle East are lifting demand for earthmoving equipment undercarriage components in parallel.

• •Commercial aircraft order books at major OEMs continue to signal multi-year production pipelines requiring landing gear systems
• •Aging global fleet requiring mid-life upgrades and component replacement across both civil and military aviation segments
• •Growth in construction, mining, and agriculture sectors driving demand for heavy equipment undercarriage and track systems

The market is commonly segmented by component type, including struts, wheels, brakes, tires, and shock absorbers, as well as by end-use verticals such as commercial aviation, military aviation, and earthmoving equipment. North America and Europe dominate current market share due to established aerospace manufacturing bases and high defense budgets, while Asia-Pacific is the fastest-growing region. Within the equipment segment, tracked vehicles for mining and construction represent a meaningful and expanding share of the broader undercarriage components market.

• •North America and Europe hold the largest share, supported by legacy aerospace OEM supply chains and strong military procurement
• •Asia-Pacific is the fastest-growing region, led by China's commercial aviation expansion and infrastructure build-out
• •Key component categories include main landing gears, nose landing gears, wheels and brakes, and undercarriage track systems for heavy equipment

What are the recent trends and outlook?

Lightweighting remains a central technology trend, with manufacturers increasingly using titanium alloys, high-strength steels, and advanced composites to reduce landing gear weight without compromising structural integrity. Electromechanical actuation and health-monitoring sensor systems are gradually replacing legacy hydraulic designs, enabling predictive maintenance and reducing aircraft weight further. The market is expected to sustain steady mid-single-digit growth through the early 2030s, supported by new aircraft programs, fleet expansion in emerging markets, and the long replacement cycles inherent in landing gear components.

• •Adoption of advanced materials and additive manufacturing processes to reduce component weight and manufacturing lead times
• •Integration of sensor-based health monitoring and predictive maintenance technologies into next-generation landing gear designs
• •Aftermarket services and MRO contracts expected to grow in importance as aging fleets require increasingly complex overhaul and repair work
