AS9100 & AS9120 Supplier Audit Support

Book a Call

Independent supplier audits to strengthen supply chain control and reduce operational risk.

Certification audits provide a snapshot in time.

They confirm whether a supplier’s management system meets AS9100 or AS9120 requirements on the day of the audit – but they don’t always explain why delivery, quality, or communication issues are occurring in practice.

We provide independent supplier audit support for organisations operating within aerospace supply chains, giving you deeper visibility of supplier performance against both aerospace requirements and your contractual expectations.

Why This Matters

AS9100 and AS9120 both require organisations to:

  • control externally provided products and services
  • evaluate and monitor supplier performance
  • manage risk across the supply chain
  • take action where supplier performance impacts quality or delivery

When issues arise – late delivery, quality escapes, poor responsiveness – relying solely on a supplier’s certification is often not enough.

Supplier audits provide direct evidence, not assumptions.

The Supplier Audit Package

This service is delivered as a structured, objective audit package, applicable to both AS9100 and AS9120 supply chains.

1. Audit Scope & Criteria Definition

We work with you to define the audit focus, including:

  • applicable AS9100 or AS9120 requirements
  • your contractual requirements or SLA expectations
  • specific performance, quality, or delivery concerns
  • risk level and criticality of the supplier

This ensures the audit is targeted and proportionate.

2. Independent Supplier Audit Execution

We carry out independent supplier audits that:

  • assess conformity to relevant AS9100 / AS9120 requirements
  • evaluate controls against your SLA or contractual obligations
  • focus on process effectiveness, not just documentation

Audits can be conducted on-site or remotely, depending on scope and risk.

3. Audit Reporting & Findings

You receive a clear, objective audit report that includes:

  • conformity and non-conformity against audit criteria
  • evidence-based findings linked to requirements
  • identification of systemic weaknesses and risk areas
  • clear distinction between contractual and standard-based findings

Reports are written to support decision-making, not confrontation.
