AS9100 Certification Body

What Is an AS9100 Certification Body?

An AS9100 certification body is:

• An accredited third-party auditing organization

• Authorized to assess compliance to AS9100

• Responsible for issuing certification upon successful audit

• Subject to oversight by accreditation authorities

They conduct:

• Stage 1 (documentation readiness) audit

• Stage 2 (full implementation and effectiveness) audit

• Annual surveillance audits

• Recertification audits every three years

Certification bodies cannot provide consulting. Their role is independent verification of compliance.

If you are early in the journey, reviewing What is AS9100 Certification may clarify the overall certification framework before engaging a registrar.

How to Choose the Right AS9100 Certification Body

Not all registrars are equal. Aerospace organizations should evaluate:

Accreditation Status

Confirm the certification body is accredited by a recognized accreditation authority. Without proper accreditation, your certificate may not be accepted by aerospace primes or regulatory stakeholders.

Aerospace Experience

Auditors must understand:

• Aerospace manufacturing controls

• Special processes

• Configuration management

• Counterfeit parts prevention

• Risk-based thinking in aerospace environments

An auditor unfamiliar with aerospace requirements increases audit friction and nonconformity risk.

Auditor Consistency

Ask about:

• Auditor rotation policies

• Lead auditor aerospace background

• Industry specialization

• Continuity across surveillance cycles

Consistency improves audit predictability.

Cost Structure

Fees typically include:

• Stage 1 audit

• Stage 2 audit

• Surveillance audits

• Travel and administrative costs

Lower upfront pricing does not always equal lower total certification cost. Audit time calculations are based on scope, headcount, and complexity.

For a broader understanding of aerospace system implementation expectations, review AS9100 Certification Requirements before engaging a registrar.

Common Mistakes When Selecting a Certification Body

Organizations often create avoidable risk by:

• Choosing solely based on price

• Not verifying aerospace audit experience

• Failing to understand audit day calculations

• Underestimating documentation readiness

• Entering Stage 2 without completing a full internal audit

These mistakes frequently result in major nonconformities and extended corrective action cycles.

A structured preparation pathway — outlined in How to Get AS9100 Certification — reduces this risk significantly.

What an AS9100 Certification Audit Looks Like

Stage 1 Audit

• QMS documentation review

• Scope confirmation

• Readiness assessment

• Identification of documentation gaps

Stage 1 is not a formality. Poor readiness here delays certification.

Stage 2 Audit

• Process effectiveness verification

• Risk management integration

• Production and operational controls

• Supplier management

• Configuration management

• Product safety controls

• Counterfeit parts prevention

• Internal audit effectiveness

• Management review effectiveness

Nonconformities must be corrected and verified before certification is granted.

Understanding the operational depth of these requirements is essential — especially if your organization manages complex customer or regulatory obligations such as Flowdown Requirements from aerospace primes.

AS9100 Certification Body vs AS9100 Consultant

Certification Body

• Conducts the audit

• Issues the certificate

• Must remain impartial

• Cannot provide implementation support

Consultant

• Builds or strengthens your QMS

• Conducts internal audits

• Aligns documentation to AS9100 Rev D

• Prepares leadership for audit interviews

• Simulates registrar-style audit conditions

Working with a consultant before engaging a registrar reduces uncertainty and protects audit outcomes.

How Long Does AS9100 Certification Take?

Typical timelines:

• 4–6 months: Small organization with a mature ISO-aligned QMS

• 6–12 months: New implementation or complex aerospace scope

Timeline depends on:

• Current system maturity

• Resource allocation

• Leadership engagement

• Internal audit completion

• Risk management integration

Organizations transitioning from ISO 9001 often benefit from reviewing ISO 9001 vs AS9100 to understand additional aerospace-specific requirements before audit scheduling.
