An aircraft strut is an axially loaded structural component engineered primarily to carry compressive forces (and, where required, tension) to support and stiffen airframe assemblies. By providing a direct load path, struts reduce bending moments in wings, tails, and fuselage frames, enabling lighter, more fatigue-resistant structures. Typical materials include high-strength aluminum and steel alloys, with titanium and advanced composites adopted where weight, corrosion resistance, or life-cycle durability are critical.

Government and defense agencies including the FAA, EASA, and the U.S. DoD govern the design, qualification, and continued airworthiness of aircraft struts through the type-certification basis for each aircraft (14 CFR/CS Parts 23, 25, 27, and 29 for structural and ground-load requirements).

Leading industry participants include Safran Landing Systems, Collins Aerospace (RTX), Liebherr-Aerospace, Héroux-Devtek, and Triumph Group for large commercial and defense programs, supported by forging and machining houses and seal/actuation specialists (e.g., Parker, Trelleborg). Airframers such as Airbus, Boeing, Embraer, Bombardier, Dassault, and Textron Aviation integrate struts into landing-gear assemblies and, in the general-aviation segment, as external lift struts.

MARKET DYNAMICS

MARKET DRIVERS

Increasing Aircraft Production and Replacement of Aging Fleets Driving Market Growth

The sustained increases in new-aircraft production and the replacement of older fleets are the single most direct demand engine for aircraft, struts especially landing-gear (oleo) struts. Every delivery requires a full shipset of main and nose-gear struts, so higher build rates translate almost one-for-one into OEM strut demand.

• For instance, Boeing Commercial Market Outlook 2025 projects 43.6k aircraft deliveries and a 49.6k-unit fleet by 2044. Therefore, the rise in aircraft production and deliveries is expected to increase the demand for aircraft struts.

As legacy aircraft approach life limits, landing-gear (oleo) struts face tighter inspection intervals and more overhauls (seals, bushings, surface restoration), lifting near-term aftermarket spend.

MARKET RESTRAINTS

High Manufacturing and Maintenance Costs to Limit Market Expansion

The aircraft strut market growth faces a key obstacle in the form of high production and lifecycle maintenance costs. Strut assemblies, particularly oleo struts, require precision forging, high-tolerance machining, specialized surface treatments (such as chrome-free or HVOF coatings), and certified hydraulic components all of which increase manufacturing expenses. Additionally, the need for periodic overhauls, fluid servicing, and replacement of seals and bushings adds to long-term operational costs for airlines and operators. These cumulative expenses often pressure procurement budgets, delay replacement cycles, and limit adoption of advanced lightweight and eco-friendly materials.

MARKET OPPORTUNITIES

Adoption of Smart and Lightweight Strut Technologies Create Space for Market Expansion

A major opportunity in the aircraft strut market lies in the integration of smart monitoring systems and growing emphasis on lightweight material technologies. The ongoing shift toward digital and data-driven maintenance is creating demand for intelligent struts equipped with embedded pressure, load, and temperature sensors that enable real-time health monitoring and predictive maintenance. This reduces unplanned downtime, improves fleet reliability, and lowers lifecycle costs for operators. Simultaneously, advancements in titanium, high-strength aluminum alloys, and carbon-composite structures are allowing strut manufacturers to achieve significant weight reductions without compromising strength or durability.

AIRCRAFT STRUT MARKET TRENDS

Integration of Additive Manufacturing and Near-Net-Shape Forging

A growing trend in the aircraft strut market is the adoption of additive manufacturing (AM) and near-net-shape forging to optimize operational efficiency and component performance. Strut manufacturers are increasingly leveraging 3D printing for fittings, end-caps, and complex internal geometries, reducing material waste and machining time compared to traditional subtractive processes. Similarly, near-net-shape forging allows for precise material distribution, minimizing the buy-to-fly ratio and improving structural integrity.

MARKET CHALLENGES

Supply Chain Constraints and Long Lead Times to Present Challenges for the Market

A key challenge in the aircraft strut market is the persistent supply chain bottleneck affecting the availability of high-grade alloys, forgings, and precision-machined components. Strut production depends on certified aerospace suppliers for titanium, high-strength steel, and hydraulic subcomponents, all of which require stringent quality assurance and traceability. Global shortages of raw materials, limited forging capacity, and extended certification cycles have led to long lead times and delayed deliveries for both OEM and aftermarket demand.
