The aircraft parts market is being fundamentally changed by relentless supply chain disruptions, quality pressures, and the increasing demands for production. McKinsey & Company indicates that the existing open-order backlog of aircraft would take 13 years to supply at delivery rates in 2023. At the same time, demand for air travel has recovered to 97% of pre-pandemic levels and is expected to increase 5-10% per year through 2026, driving high demand for aircraft components.

Of all the segments, pneumatics/hydraulics are among the fastest-growing. The value of the aircraft hydraulic systems market was USD 12.2 billion in 2024 with a projected USD 36 billion by 2034 CAGR of 11.5%. The fuel systems market is progressing too, driven by fuel efficiencies and sustainability (from USD 10.6 billion in 2024 to a CAGR of 5.2% to 2034).

Braking systems and landing gear appear to be relatively stable in defense and commercial sectors. The aerospace landing gear and systems market will exceed USD 25.2 billion by 2034. In addition, the demand for cabins and interior systems is increasing; the commercial airplane cabin interior sector went from USD 6.6 billion in 2024 (now 3-4 years out with the tight architectures) to a projected CAGR of approximately 7.8% to 2034.

Defense upgrades are the biggest contribution to growth in ammunition, weapons, and environmental control systems, but resilient supply chain efforts such as cross-functional work and sub-tier visibility improved component shortages by over 25%.
