Across the aerospace industry, uncompromising quality assurance and quality control are essential. That’s precisely why it’s important to evaluate suppliers based on recognized aerospace 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 can withstand demanding aerospace applications.

Why Aerospace Quality Certifications Matter to Tier-1 Procurement

Tier 1 aerospace companies can’t afford to take even small risks within their supply chains. For these organizations, working with manufacturers that maintain recognized industry certifications provides an added level of confidence in quality, compliance, and performance.

There are three key certifications procurement teams often look for, each supporting supply chain reliability in different ways:

Nadcap accreditation verifies that critical manufacturing processes meet industry-standard audit requirements.
AS9100D certification confirms that a supplier operates a compliant aerospace quality management system.
FAA repair station certification indicates that an organization holds a Part 145 certificate authorizing regulated aircraft maintenance and repair operations.

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

Nadcap Accreditation: Controlling Critical Aerospace Processes

Nadcap, originally the National Aerospace and Defense Contractors Accreditation Program, administered by the Performance Review Institute (PRI), provides standardized audits for critical aerospace manufacturing processes such as welding, heat treatment, and chemical processing.

By establishing a consistent auditing framework across the aerospace, defense, and space industries, Nadcap helps ensure suppliers maintain rigorous process control and traceability. Many Tier-1 OEMs require suppliers to hold Nadcap accreditation for specific critical processes.

AS9100D: The Aerospace Quality Management Standard

AS9100D is the internationally recognized standard for aerospace quality management systems. Developed by the International Aerospace Quality Group (IAQG) and published by SAE International, AS9100D ensures manufacturers maintain the systems and controls required to meet strict regulatory and customer requirements.

This certification demonstrates that a manufacturer has established repeatable processes for quality management, documentation, traceability, and continuous improvement across aerospace production programs.

FAA Repair Station Certification: Regulatory Approval for Aircraft Maintenance

14 CFR Part 145 Air Agency Certification is awarded by the Federal Aviation Administration (FAA) to repair stations that meet the agency’s stringent standards for aircraft maintenance and repair operations.

Many OEMs prefer working with FAA-certified repair stations because the organization already meets federal regulatory requirements under Part 145. It can also be advantageous to partner with companies that maintain FAA repair station certifications across multiple locations. Both NMG Aerospace’s Ohio and Arizona facilities hold FAA repair station certifications.
