Why are aircraft struts gaining commercial importance?

Aircraft struts perform structural load-bearing functions across landing gear, wing support, and fuselage bracing systems. Their ability to withstand repeated mechanical loads, landing impacts, vibration, and operational stress makes them a qualification-sensitive component within aircraft manufacturing and maintenance programs.

Commercial aviation is creating the largest demand pool as airlines expand fleets and replace older aircraft. New aircraft deliveries from Boeing and Airbus production lines translate directly into OEM procurement requirements for qualified landing gear components. Fleet renewal also creates opportunities for suppliers that can maintain consistent production quality across multiple aircraft programs.

The aftermarket provides another source of recurring demand. Landing gear systems undergo scheduled inspection, overhaul, and replacement activity, creating a replacement cycle that can extend across 8 to 12 years. As the installed commercial aircraft fleet ages, MRO providers require replacement struts that meet approved specifications and fit established landing gear architectures.

Military aviation adds another layer of demand. Modernization programs in NATO countries, India, and Asia Pacific are supporting procurement of high-specification aircraft components. Military aircraft struts must meet demanding qualification and performance requirements, making certification capability and manufacturing consistency important competitive factors.

Which aircraft strut products and applications are shaping demand?

Landing gear struts are expected to remain the leading product category, accounting for 70.0% of the market in 2026. These components absorb impact loads during touchdown and support aircraft weight during ground operations, making them among the most structurally critical strut applications.

Commercial aviation is projected to account for 60.0% of application demand. Passenger aircraft fleet expansion, airline renewal programs, and increasing aircraft utilization are supporting procurement of landing gear components. Commercial aircraft operators also generate long-term aftermarket requirements as landing gear systems enter scheduled overhaul cycles.

Original equipment manufacturers are expected to dominate the end-use segment with a 65.0% share. OEM programs require suppliers to meet detailed engineering specifications, qualification requirements, delivery schedules, and long-term production consistency. This creates high barriers to entry for manufacturers without established aerospace approvals and production capabilities.

Metal alloys remain the dominant material category, accounting for 75.0% of demand. High-strength steel, titanium, and aluminum alloys provide the load-bearing performance required for aircraft structural applications. Composite materials offer an alternative for applications where weight reduction and material efficiency can justify higher qualification and manufacturing complexity.

What does the analyst see as the key commercial issue?

The aircraft strut market is evolving around qualification-driven procurement, established aerospace supply chains, and the need for consistent structural performance. Suppliers that can meet demanding specifications while maintaining reliable production and delivery schedules are likely to strengthen their position as commercial and military aircraft programs expand.

Competitive advantage is increasingly linked to integrated manufacturing capabilities and qualified supply positions. For aircraft OEMs and MRO providers, supplier reliability matters alongside component performance because strut replacement and installation must align with approved aircraft configurations and maintenance requirements.
