Industry Overview: Market Size & Growth Drivers#

The Other Aircraft Parts Manufacturing industry is a cornerstone of global aerospace, driven by demand for commercial, military, and private aviation.

Market Size#

• Global: The global aerospace parts manufacturing market was valued at approximately $1,003 billion in 2025** and is projected to grow at a CAGR of 5.4$279.6 billion in revenue by 2026 (IBISWorld, 2026).
• U.S.: The U.S. aerospace and defense industry employed over 2.23 million workers and generated $995 billion in total sales** in 2024, with exports reaching **$172.7 billion in 2025 (Aerospace Industries Association, 2025).

Growth Drivers#

1. Rising Air Travel: Continued recovery and growth in global air travel demand has boosted orders for new commercial aircraft (e.g., Boeing 737 MAX, Airbus A320neo), increasing demand for parts. Persistent production backlogs are prompting operators to fly existing fleets longer, further driving aftermarket parts demand.
2. Aging Fleet Replacement: Global airlines are retiring older aircraft in favor of fuel-efficient models, driving demand for new parts. The aftermarket MRO sector is projected to grow at a 3.2% CAGR between 2026 and 2035 (Aviation Week, 2025).
3. Defense Spending: Governments worldwide are investing in military aircraft modernization, autonomous systems, and drones, supporting demand for defense-specific parts. U.S. defense priorities are increasingly focused on accelerating AI-enabled systems and collaborative combat aircraft.
4. Technological Advancements: Innovations like lightweight composites, additive manufacturing (3D printing), and smart materials are improving part performance and reducing costs. The aerospace 3D printing market alone was valued at $4.04 billion in 2025 (Fortune Business Insights, 2025).

Regulatory & Compliance Requirements#

Aerospace manufacturing is one of the most heavily regulated industries, and NAICS 336413 businesses must adhere to strict standards to ensure safety and reliability.

Key Regulatory Bodies#

• FAA (Federal Aviation Administration): U.S. manufacturers must comply with FAR Part 21 (Certification Procedures for Products and Parts), which requires parts to meet airworthiness standards.
• EASA (European Union Aviation Safety Agency): For European markets, compliance with EASA Part 21G (Production Organization Approval) is mandatory.
• ISO/AS Standards: The AS9100 quality management system is the global benchmark for aerospace manufacturing, covering design, production, and testing. AS9100 is currently transitioning to IA9100, aligning with the ISO 9001:2026 revision and incorporating tighter supply-chain and digital assurance practices (Quality Magazine, 2026).

Additional Compliance#

• Export Controls: Parts may be subject to ITAR (International Traffic in Arms Regulations) or EAR (Export Administration Regulations) if they have military applications or are sold to restricted countries.
• Environmental Regulations: Compliance with REACH (EU) and RoHS (Restriction of Hazardous Substances) to limit toxic materials in parts.
• Traceability: Parts must be traceable throughout their lifecycle (e.g., batch numbers, material certifications) to enable recalls if needed.

Major Players & Market Trends#

The industry is dominated by large multinational corporations, but also includes specialized small and medium-sized enterprises (SMEs).

Key Players#

• Collins Aerospace (RTX Corporation): One of the world's largest aerospace suppliers, formed in 2018 from the merger of Rockwell Collins and UTC Aerospace Systems. Produces landing gear, avionics, interiors, and power systems.
• Honeywell Aerospace: Produces APUs, hydraulic systems, avionics, and flight controls. Honeywell is spinning off its aerospace division as a standalone publicly traded company in the second half of 2026, creating one of the largest pure-play aerospace suppliers.
• Safran: A French multinational specializing in landing gear, braking systems, and electrical components. In 2025, Safran finalized its $1.8 billion acquisition of Collins Aerospace's actuation and flight control activities, solidifying its position as a world leader in flight controls.
• TransDigm Group: A leading U.S.-based producer of highly engineered aerospace components. TransDigm reported **$8.8 billion in annual revenue** for 2025 and has a market capitalization exceeding$75 billion.
