Understanding the Difference Between AS9100D and NADCAP
If you’re in aerospace or defense, you’ve probably heard of AS9100D and NADCAP. Both are important for quality and compliance, but they serve different purposes. Knowing the difference can help you make better decisions for your business.
What is AS9100D?
AS9100D is a Quality Management System (QMS) standard designed specifically for the aerospace, space, and defense industries. Think of it as the foundation for managing quality across your entire organization.
What AS9100D Covers:
Risk-based thinking to prevent problems before they happen
Product safety and counterfeit part prevention
Supplier management and oversight
Configuration management (keeping track of product changes)
Human factors that impact quality
It builds on ISO 9001, adding aerospace-specific requirements to make sure your whole quality system meets industry demands.
What is NADCAP?
NADCAP stands for National Aerospace and Defense Contractors Accreditation Program. Unlike AS9100D, NADCAP focuses on specialized processes within aerospace manufacturing.
These include things like:
Heat treating
Welding
Coatings and plating
Non-destructive testing
Chemical processing
NADCAP audits these specific processes to confirm they meet strict customer and regulatory standards.
Why Do They Exist?
AS9100D exists to provide a comprehensive framework for aerospace companies to build and maintain quality management systems that cover all parts of their operation.
NADCAP exists to provide industry-wide accreditation for specialized manufacturing processes, ensuring consistent quality and reducing duplicate audits for suppliers.
Who Needs Them?
AS9100D: Aerospace manufacturers, suppliers, and service providers aiming to manage quality across their entire organization.
NADCAP: Suppliers performing specialized processes requiring rigorous technical evaluation.
Understanding these differences helps you target the right certifications, improve your quality processes, and avoid unnecessary audits.
