AS9100
Understanding AS9100 Quality Management
If an RF component manufacturer wants to sell a bandpass filter to Boeing, Lockheed Martin, or Airbus, they must first demonstrate that their quality management system meets the rigorous requirements of AS9100. This standard ensures that every product leaving the factory is built, tested, and documented to the level of rigor that aviation safety demands.
Beyond ISO 9001
AS9100 builds on the foundation of ISO 9001 (the generic quality management standard used across all industries) but adds approximately 100 additional requirements specific to aerospace. Key additions include:
- Product safety: Formal processes for identifying and managing product safety risks.
- Configuration management: Ensuring that the physical product exactly matches the approved design documentation.
- First Article Inspection (FAI): AS9102 requirements for comprehensive inspection of the first production unit.
- Special processes: Qualification and control of processes where output quality cannot be fully verified by inspection alone (soldering, plating, bonding).
Certification and Auditing
AS9100 certification is issued by accredited third-party registrars following an on-site audit of the organization's QMS implementation. Certification is maintained through periodic surveillance audits. The IAQG's OASIS database provides a publicly searchable registry of all AS9100-certified organizations worldwide.

Frequently Asked Questions
Is AS9100 mandatory for selling RF components to defense contractors?
Not legally mandatory, but practically essential. Major defense prime contractors (Raytheon, Northrop Grumman, L3Harris) require AS9100 certification as a minimum condition for supplier qualification. An uncertified RF component manufacturer will be excluded from virtually all aerospace and defense procurement opportunities, regardless of their technical capabilities.
What is First Article Inspection and why does it matter for RF?
First Article Inspection (AS9102) requires comprehensive measurement and documentation of every specification dimension and requirement on the first production unit of a new part or after a significant process change. For an RF filter, this means complete S-parameter testing, dimensional inspection, environmental screening, and comparison against every requirement in the drawing and specification. FAI proves that the production process can consistently produce conforming product before full-rate production begins.
How does AS9100 address counterfeit parts?
AS9100 Rev D includes explicit requirements for counterfeit parts prevention, referencing AS5553 and related standards. Organizations must implement processes to detect and prevent the purchase, receipt, and installation of counterfeit or suspect parts. This includes supplier controls, incoming inspection, traceability, and reporting procedures — integrating counterfeit prevention into the broader quality management framework.
