Counterfeit-parts prevention plan missing supplier-tier traceability.
Your supplier qualification doesn't verify the source-of-source for cast and forged parts.
"AS9100D §8.1.4 requires the organization to plan, implement, and control processes for the prevention of counterfeit or suspect-counterfeit-part use. The plan must address training, parts-availability monitoring, traceability of parts and components, processes for confiscation and quarantine, and supply-chain risk identification."
QA-PROC-008 Rev 02 documents incoming inspection and source-traceability requirements but stops at Tier-1 suppliers. The plan does not require Tier-1 to flow source-traceability requirements to Tier-2 distributors of cast aluminum and forged steel components — both flagged by NIST as high counterfeit-risk classes for aerospace. The §8.1.4 plan names no method for verifying source-of-source on these classes, so a Tier-2 distributor substitution would pass incoming inspection undetected.
