Across the aerospace industry, uncompromising quality assurance and control are nothing less than critical. That’s precisely why it’s important to look for specific quality certifications when choosing an aerospace manufacturer. The right certifications signify that a manufacturer has proven processes for delivering high-performance products and services that will hold up to unforgiving aerospace applications.

In this article, we’ll take a look at some of the certifications you should keep an eye out for and why they’re so crucial.

Why Aerospace Quality Certifications Matter to Tier 1 Procurement

Tier 1 aerospace companies can’t afford to take any risks, however small they might be. For these organizations, purchasing from a manufacturer with industry certifications provides much more peace of mind.

There are three key certifications that are good to look for, and they matter for different yet overlapping reasons:

Nadcap certifications confirm that a manufacturer follows industry-recognized, standardized audit processes.
AS9100D certification reflects a manufacturer’s adherence to this globally recognized standard for quality management systems.
FAA repair station certification communicates that a manufacturer has been certified by the FAA to perform maintenance and repairs on aircraft.

Let’s take a closer look at each of these certifications and how they benefit Tier 1 procurement.

Nadcap Certifications: Controlling Critical Aerospace Processes

The Nadcap program, originally the National Aerospace and Defense Contractors Accreditation Program, provides industry-wide governance in the form of standardized audits. Under Nadcap, original equipment manufacturers (OEMs) across the aerospace, defense, and space industries come together to oversee critical process audits. The Nadcap program ensures all certificate holders follow the same high standards and enhances supply chain performance. Many Tier 1 OEMs require their suppliers to have Nadcap certifications.

AS9100D: The Standard for Aerospace Manufacturing Quality

AS9100D is an international standard for quality management systems to ensure they “meet customer and applicable statutory and regulatory requirements.” Established by SAE International, AS9100D is the latest revision of the original AS9100 standard. This certification ensures that a manufacturer is able to meet the stringent quality management requirements of the aerospace industry.

FAA Repair Station Certification: Authority That Speeds Acceptance

14 CFR Part 145 Air Agency Certification is awarded by the Federal Aviation Administration (FAA) to repair stations that meet the agency’s exacting standards. OEMs generally prefer working with FAA-approved partners simply because it’s easier—Part 145 stations already meet federal compliance. It’s also beneficial to work with organizations that maintain FAA-certified repair stations in multiple locations. Both NMG’s Ohio and Arizona locations are certified by the FAA.
