1.1 — AS9100: The Aerospace Quality Management Standard

AS9100 builds directly on the ISO 9001:2015 foundation discussed in RR Hydraulic’s dedicated ISO 9001:2015 reference, adding aerospace- industry-specific requirements: enhanced configuration management, risk management integrated throughout the quality system, first article inspection requirements more rigorous than the general EPC FAI practice discussed throughout RR Hydraulic’s other references, and specific requirements for controlling and flowing down customer and regulatory requirements through the entire supply chain. A manufacturer or supplier’s AS9100 certification (rather than ISO 9001 alone) is frequently a mandatory qualification requirement for supplying aerospace-critical fasteners and components, reflecting the aviation industry’s structured, globally harmonised approach to quality management across its extended supply chain.

1.2 — NADCAP: Special Process Accreditation

1.3 — Full Lot Traceability and Genealogy

Aerospace and defence component traceability requirements generally exceed the standard EN 10204 3.1/3.2 material certification discussed throughout RR Hydraulic’s other materials references — “genealogy” traceability requires documented, unbroken linkage from the original raw material heat/lot, through every manufacturing and processing step (forging, heat treatment, machining, coating, inspection), to the specific finished part serial or lot number. This complete process genealogy — not merely a material certificate confirming the final chemical composition and mechanical properties — is frequently a mandatory contractual and regulatory requirement for aerospace-critical and defence-critical components, supporting root-cause investigation in the event of an in-service quality issue and providing the audit trail regulatory bodies and prime contractors require for airworthiness and defence procurement oversight.

2.1 — Material Selection by Component Category

2.2 — AMS, MS, and NAS Specification Framework

3.1 — Counterfeit Parts Prevention: AS5553 and AS6174

3.2 — Export Control Awareness: ITAR and EAR

Certain defence articles, technical data, and, in some cases, aerospace-related hardware and materials are subject to export control regulations — in the United States, the International Traffic in Arms Regulations (ITAR) governing defence articles and services, and the Export Administration Regulations (EAR) governing a broader range of dual-use and commercial items with potential military application. These regulations govern the export, re-export, and, in some cases, even the disclosure of controlled technical data to foreign persons, with significant legal consequences for non-compliance. RR Hydraulic’s customers with defence or controlled aerospace procurement requirements should confirm the applicable export control classification for their specific components and technical data, and ensure their own internal compliance program addresses any export control obligations relevant to their procurement — this is a customer and regulatory compliance matter that sits alongside, and is conceptually distinct from, the material and quality specifications discussed throughout this reference.

3.3 — Configuration Control and Change Management

Aerospace and defence components are typically subject to strict configuration control — any change to the approved manufacturing process, material source, or specification for a qualified part requires formal review and, frequently, customer/regulatory re-approval before implementation, distinct from the more flexible process improvement latitude common in general industrial manufacturing. This reflects the extensive qualification and certification basis (design approval, airworthiness certification, or defence procurement qualification) underlying the original part approval, which an unapproved change could invalidate — always confirm the applicable configuration control requirements and change notification obligations for aerospace/defence component supply before implementing any process, material source, or specification modification.

4.1 — Inspection & QC Protocol

4.2 — Documentation Requirements

4.3 — Applications by Sector

4.4 — Export Packaging Specification

• Components packed with full genealogy documentation and lot traceability maintained through packing and shipment, per the traceability requirements discussed throughout Part 1
• Clear part number, specification (AMS/MS/NAS), and lot/serial marking on each item and its packaging to support the aerospace-standard traceability chain
• Components segregated by material grade and configuration with distinct labelling to prevent any risk of substitution or mix-up given the safety-critical nature of this application category
• Documentation in a waterproof pocket: EN 10204 3.1/3.2 MTC, full genealogy report, NADCAP special process certificates (where applicable), AS9102 first article inspection report, and packing list referenced to the specific part number/revision
• Export documentation coordinated with the customer’s own export control compliance program per Section 3.2, with appropriate country of origin and HS tariff code documentation matched to the specific component category
