AS9100 Rev D

AS9100 Rev D is the aerospace quality management system (QMS) standard used by organizations in the aviation, space and defense sectors. It is based on ISO 9001:2015 and adds sector-specific requirements for risk management, configuration control, product safety, counterfeit part prevention, and traceability.

The standard is typically applied to organizations that design, manufacture, maintain, or distribute aerospace products and services, including OEMs, tiered suppliers, and MRO providers. In operations, AS9100 Rev D commonly shapes procedures and records around:

• Documented processes for planning, production, inspection, test, and delivery
• Configuration management and change control for parts, software, and documentation
• Nonconformance management, MRB decisions, and corrective action
• Traceability of materials, components, and work orders
• Supplier evaluation, flowdown of requirements, and purchasing controls
• Risk-based thinking, operational risk assessment, and product safety

AS9100 Rev D itself is a requirements document for building and maintaining a QMS. It is not a software system or a specific tool, although MES, ERP, PLM, and QMS software are often configured to help organizations implement and demonstrate conformity to its requirements.

Common confusion

AS9100 Rev D is related to, but distinct from:

• ISO 9001:2015: AS9100 Rev D includes all ISO 9001:2015 requirements plus additional aerospace-specific requirements.
• AS9102: AS9100 Rev D covers the overall QMS, while AS9102 focuses narrowly on First Article Inspection (FAI) requirements.
• AS9110 and AS9120: These are related aerospace QMS standards for maintenance organizations (AS9110) and stockist distributors (AS9120), whereas AS9100 is broader and commonly applied to manufacturers and design organizations.

Use in industrial and regulated environments

In regulated aerospace manufacturing, AS9100 Rev D is frequently referenced in procedures, supplier contracts, internal audits, and customer audits. It influences how organizations structure:

• Document control and version governance for work instructions, routings, and records
• Quality planning, inspection plans, and sampling strategies
• Data capture in MES/ERP systems for traceability and genealogy
• Internal process audits, layered process audits, and management review

AS9100 Rev D is commonly used as a framework to align quality, production, and supply chain processes, but it does not dictate specific software products, configurations, or certification outcomes.
