1.The Traceability Problem You Did Not See Coming
The call comes from your customer's quality department. A part you shipped three months ago has been flagged during final assembly. The material certification does not match the purchase order requirements. They need you to trace that part back to its source. They need the original manufacturer's test reports. They need to know every hand that touched it between the manufacturer and their dock.
You pull the shipping records. You find the receiving documentation. But somewhere in the middle, the trail gets murky. Different lot numbers appear on different documents. The material certification is a scan, not an original. You cannot definitively prove that the certificate in your file corresponds to the physical part in their assembly.
2.What is AS9120?
AS9120 is the aerospace quality management system standard for organizations that procure, stock, and distribute aviation, space, and defense products. Unlike AS9100, which addresses manufacturing, AS9120 focuses on the unique requirements of distribution operations.
The current version, AS9120 Rev B, aligns with ISO 9001:2015 structure and AS9100 Rev D requirements while tailoring them for distribution context. It addresses the specific risks and controls relevant to organizations that do not manufacture products but play critical roles in the aerospace supply chain.
Why Certification Matters
3.Why Distributors Face Unique Challenges
1Documentation Integrity
Distributors receive products with documentation from manufacturers. They must preserve that documentation and transfer it accurately to customers. Original documentation must be distinguished from copies, and certificates must trace back to the actual products they represent.
2Counterfeit Prevention
Aerospace distribution has been targeted by counterfeit parts. Even authorized channels occasionally experience infiltration. Distributors need inspection and verification processes that can detect counterfeits when they appear.
3Product Preservation
Aerospace parts often have specific handling, storage, and shelf life requirements. Electronic components may be moisture sensitive. Chemicals may have expiration dates. Distributors must maintain conditions that preserve product integrity.
4Traceability Through the Chain
Complete traceability from manufacturer to end user is essential. When problems occur, the industry must identify all affected products. Distributors must maintain records that support both trace forward and trace back investigations.
4.Key Requirements of AS9120
Operational Planning and Control
- Determine requirements for products including quality and documentation
- Establish controls for receiving, handling, storage, preservation, and delivery
- Records must demonstrate that requirements were met
Control of Externally Provided Products
- Supplier selection must ensure procurement from legitimate sources
- Verification activities must confirm products and documentation meet requirements
- Authorization from original manufacturer or authorized network must be verified
Counterfeit Part Controls
- Define processes for controlling risk of counterfeit parts
- Train personnel to detect counterfeits
- Control and report suspect or confirmed counterfeit parts
Identification and Traceability
- Products must be identified throughout receipt, storage, and shipment
- Traceability must link products to sources and documentation
- Lot integrity requirements prevent unintentional lot mixing
5.Common Implementation Challenges
Inventory Management Integration
Documentation Volume
Supplier Qualification
6.Building Value Through Quality
Quality systems in distribution can feel like overhead. They do not create products. They add steps to processes. They require documentation that seems to slow things down.
But for aerospace distributors, quality systems create value. They provide assurance to customers who need confidence in their supply chains. They reduce the risk of quality escapes that damage relationships and create liability.
