AS9100 Frequently Asked Questions (FAQs)

At Core Business Solutions, we specialize in helping American small businesses navigate the complex requirements of aerospace and defense certifications. Below, we’ve compiled and ranked the most frequently asked questions about AS9100, based on the issues that generate the most interest and concern among our customers.

What is AS9100?

The AS9100 standard is an international quality standard that defines minimum requirements for a company’s processes to enhance the safety of its products and its performance for customers. AS9100 (AS9100D) is written for companies in the aviation, space, and defense industries. It is based on the ISO 9001 standard.

Watch this short video to learn more about AS9100 and the steps to achieve certification.

1. How hard is it to get AS9100 certified?

Achieving AS9100 certification takes work, but it’s entirely achievable for small businesses with the right guidance. If your company is already ISO 9001 certified, you’re approximately 75% of the way there. The additional requirements focus on aerospace-specific needs such as risk management, special processes, and counterfeit part prevention. While the certification process usually takes 3 to 6 months, the payoff is significant—AS9100 opens new markets, strengthens your reputation, and demonstrates a high commitment to quality and customer satisfaction.

2. What are the common AS9100 audit questions?

Audit preparation is one of the biggest challenges small businesses face. Typical AS9100 audit questions include:

• What is your quality policy?
• What are your quality objectives?
• How do you control and maintain documentation?
• Do you have an internal audit schedule?
• How do you manage findings from an internal audit?
• How do you determine requirements for products and services?

Auditors want proof that your quality management system (QMS) is documented. They also want to see that it is used and improved regularly.

3. What are the key points of AS9100?

AS9100 builds on ISO 9001 but adds requirements specific to aerospace, space, and defense industries. Key elements include:

• Control of work transfers between facilities or suppliers.
• Control of Foreign Object Debris (FOD) in the production process.
• Emphasis on the importance of ethical behavior.
• Risk identification and management are tied to product quality and delivery.
• Configuration management to maintain control over product design and changes.
• Regulatory approvals and compliance with aviation and defense authorities.

4. What are the different types of AS9100 audits?

Businesses pursuing certification encounter three main types of audits:

• Internal audits: Conducted by your own staff (or consultants) to check compliance.
• External audits: Performed by a registrar or certification body to issue certification.
• Customer audits: Some aerospace customers conduct their own supplier audits to verify compliance with AS9100 and their specific requirements.

5. What is risk-based thinking in AS9100?

AS9100 embeds risk-based thinking throughout its framework. It requires organizations to:

• Identify risks that may cause processes or quality results to fail.
• Put preventive measures in place to minimize those risks.
• Look for opportunities to improve and gain a competitive edge.

This proactive approach manages risks before they become costly issues.

6. What does AS9100 Rev D stand for?

AS9100 Rev D (sometimes referred to as AS9100D) is the latest version of the standard, formally known as SAE AS9100D. It defines the QMS requirements for companies that design, develop, or manufacture products for aviation, space, and defense. It was created by the International Aerospace Quality Group (IAQG). It includes ISO 9001:2015 requirements and adds aerospace-specific improvements.

7. What are “special processes” in AS9100?

Special processes involve manufacturing or service processes that inspectors cannot fully verify through inspection alone. Examples include welding, heat treating, and coating. Because these cannot be checked 100% after the fact, they must be strictly controlled through approvals, training, monitoring, and documented procedures.

8. What are some methods to prevent counterfeit parts (AS9100 clause 8.1.4)?

Counterfeit part prevention is critical in aerospace and defense. Methods include:

• Training staff in counterfeit awareness.
• Procuring only from trusted or authorized sources.
• Tracking part traceability to OEMs or approved distributors.
• Conducting inspections, tests, or chemical analyses.
• Monitoring industry databases for alerts.
• Isolating and reporting any suspected counterfeit components.

9. Does AS9100 require a quality manual?

Unlike older versions, AS9100 Rev D does not require a formal “quality manual.” Instead, it requires documented information that demonstrates the effectiveness of your QMS. Some companies still keep a quality manual for clarity and ease. However, it is not necessary unless customers or regulators ask for it.

10. Is a Management Representative required?

Yes, in the standard it states that top management shall appoint a specific member of the organization’s management, identified as the management representative, who shall have the responsibility and authority for oversight of the above requirements. The management representative shall have the organizational freedom and unrestricted access to top management to resolve quality management issues.

11. What is the objective of configuration management?

Configuration management ensures that every aerospace product is fully documented, traceable, and controlled through its entire life cycle—from design to production, maintenance, and modification. This guarantees that all parties work with consistent and accurate information, which is critical in aerospace safety and compliance.

412. What are the related quality standards in aerospace?

The AS9100 family of standards includes:

• AS9100: Design, development, production, and maintenance.
• AS9110: Maintenance and repair organizations.
• AS9120: Distributors and warehouses.

Together, they form a comprehensive quality framework for the entire aerospace supply chain.

13. What is ITAR and how does it relate?

The International Traffic in Arms Regulations (ITAR) govern the export and import of defense-related items. While not part of AS9100 itself, ITAR compliance often overlaps with aerospace businesses. Companies must ensure they meet both AS9100 and ITAR requirements to operate legally in defense contracting.

14. What is the new name for AS9100?

The AS9100 standard is transitioning to a new designation: IA9100, standing for International Aerospace. While the core requirements remain, this reflects the truly global nature of aerospace quality standards.

15. What does a comprehensive aerospace quality management system look like?

A strong AS9100-compliant QMS integrates:

• ISO 9001’s foundation.
• Aerospace-specific elements like risk, configuration, and change management.
• Project management and supplier oversight.
• A culture of continuous improvement.

This integrated system ensures safety, reliability, and customer trust across the aerospace supply chain.
