Top 10 AS9100 Certified CNC Machine Shops in the USA (2026)

When it comes to aerospace manufacturing, AS9100 certification isn't just a nice-to-have — it's a requirement. AS9100 is the internationally recognized quality management standard for the aviation, space, and defense industries. It builds on ISO 9001 with additional requirements specific to aerospace, including risk management, configuration management, and product safety.

Why AS9100 Certification Matters

Aerospace components demand the highest levels of precision and reliability. A single defective part can have catastrophic consequences. AS9100 certification ensures that a machine shop has:

- Rigorous quality control processes throughout every stage of production
- Full traceability of materials and processes
- Documented risk management procedures
- Continuous improvement programs
- Compliance with FAA, EASA, and DoD requirements

Finding the Right AS9100 Shop for Your Project

When selecting an AS9100 certified machine shop, consider these factors:

1. Specific capabilities — Does the shop offer the machining processes you need (5-axis, Swiss turning, EDM, etc.)?
2. Material expertise — Can they work with aerospace-grade alloys like Inconel, titanium, and aluminum 7075?
3. Production volume — Some shops specialize in prototyping while others handle high-volume production runs.
4. Lead times — Aerospace projects often have tight deadlines. Ask about typical turnaround times.
5. Additional certifications — Many AS9100 shops also hold ITAR registration, Nadcap accreditation, or ISO 13485 for medical devices.
