The Evolution of Aerospace and Defense Compliance: ITAR, AS9100D, and CMMC
The Evolution of Aerospace and Defense Compliance: ITAR, AS9100D, and CMMC
Throughout the history of the Aerospace and Defense industry, regulations, standards, and certification requirements have evolved in response to new challenges. As technology advanced, supply chains expanded, and threats became more sophisticated, manufacturers were asked to meet increasingly rigorous expectations for quality, security, and accountability.
The development of the International Traffic in Arms Regulations (ITAR), AS9100, and the Cybersecurity Maturity Model Certification (CMMC) reflects how industry priorities have changed over time. Each serves a different purpose, but all three address risks that can affect the Aerospace and Defense supply chain.
Understanding why these requirements were introduced helps manufacturers, OEMs, and suppliers place today’s compliance expectations in context—and prepare for how those expectations may continue to evolve.
ITAR: Protecting Controlled Defense Technology
The first major compliance challenge facing the Aerospace and Defense industry was controlling the export and transfer of sensitive military technology.
In 1976, the United States enacted the Arms Export Control Act, which provides statutory authority for defense trade controls administered through ITAR. The U.S. Department of State’s Directorate of Defense Trade Controls oversees ITAR requirements for defense articles, defense services, and related technical data identified on the United States Munitions List.
The risk extends beyond finished military products. Engineering drawings, technical specifications, manufacturing processes, software, and other technical data can reveal valuable information about U.S. defense capabilities.
Organizations working with ITAR-controlled articles, services, or technical data may be required to restrict access, maintain appropriate registrations and authorizations, and prevent unauthorized exports or disclosures. The exact obligations depend on the products, data, transactions, and contractual requirements involved.
ITAR established an enduring compliance priority for the defense industrial base: protecting controlled technology from unauthorized access or transfer.
AS9100D: Creating Consistent Quality Across the Supply Chain
As Aerospace and Defense manufacturing expanded throughout the 1980s and 1990s, a different challenge emerged. Major manufacturers increasingly depended on broad supplier networks, with components and assemblies sourced from organizations using different quality systems and procedures.
Quality problems at one supplier could affect larger assemblies, delay production, increase costs, or create safety concerns. General quality standards provided a foundation, but the industry needed a shared framework tailored to aviation, space, and defense manufacturing.
AS9100 was introduced in 1999 as an industry-specific quality management standard built upon ISO 9001. It added requirements for areas such as risk management, configuration management, product safety, traceability, supplier control, and continuous improvement.
The current AS9100D revision places additional emphasis on risk-based thinking, product safety, counterfeit-parts prevention, organizational context, and managing changes throughout the product lifecycle.
The objective is to establish a common quality framework that can be used throughout the global supply chain. While ITAR addresses controlled defense trade and technical data, AS9100D focuses on whether an organization’s quality management system can consistently deliver conforming products and services.
CMMC: Addressing a New Era of Cybersecurity Risk
Digitization introduced another category of risk. Engineering drawings, customer specifications, manufacturing records, and other sensitive information that had once remained in physical archives began moving electronically throughout the supply chain.
At the same time, cyberattacks targeting government agencies, defense contractors, and manufacturers became more frequent and sophisticated. The Department of Defense recognized that a cybersecurity weakness within even a small supplier could expose sensitive information.
For years, contractors were largely responsible for self-attesting to applicable cybersecurity requirements. Concerns about inconsistent implementation and verification contributed to the development of CMMC.
Introduced in 2020, CMMC created a framework for assessing and verifying the information-security practices of organizations that process, store, or transmit Federal Contract Information (FCI) or Controlled Unclassified Information (CUI). Unlike AS9100D, CMMC does not evaluate physical product quality. Its purpose is to assess whether contractor information systems provide the required level of protection for sensitive government information.
CMMC has since moved from an emerging initiative to an active component of defense contracting. The Department of Defense is phasing CMMC requirements into applicable solicitations and contracts, with the required level and assessment type determined by the information involved and the contract requirements.
Not every organization follows the same assessment path. Depending on the required CMMC level, an organization may complete a self-assessment or undergo an assessment by an authorized third party or the government, along with required affirmations of continuing compliance.
How ITAR, AS9100D, and CMMC Differ
Although these requirements may overlap within the same defense program, they are not interchangeable. Each addresses a different area of risk.
ITAR: Focuses on export controls governing defense articles, defense services, and related technical data. It can apply to organizations involved with ITAR-controlled items, information, services, or transactions.
AS9100D: Focuses on quality management and the consistent delivery of conforming products and services. It applies to aviation, space, and defense organizations and suppliers that maintain or pursue certification to the standard.
CMMC: Focuses on cybersecurity safeguards and verification for Federal Contract Information and Controlled Unclassified Information. It applies to Department of Defense contractors and subcontractors when required by an applicable solicitation or contract.
A Common Theme: Managing Emerging Risks
Looking back, the progression from ITAR to AS9100 and CMMC reveals a consistent pattern. Each was developed to address a specific category of risk facing the Aerospace and Defense industry.
ITAR addresses the need to control defense trade and protect sensitive technology. AS9100D provides a framework for quality, consistency, and risk management across complex supply chains. CMMC helps verify that contractors and subcontractors are protecting sensitive government information in an increasingly connected digital environment.
As technologies, manufacturing methods, and cybersecurity threats continue to advance, compliance requirements will evolve alongside them. The underlying objective remains the same: reducing risk and strengthening the Aerospace and Defense supply chain.
What These Requirements Mean When Selecting a Manufacturing Partner
For Aerospace and Defense OEMs and Tier suppliers, compliance cannot be isolated within a single department. Quality systems, information security, supplier controls, documentation, traceability, and employee training must work together.
When evaluating a manufacturing partner, organizations may consider:
- Whether the supplier maintains an appropriate aerospace quality management system.
- How drawings, specifications, and customer information are received, stored, accessed, and shared.
- Whether access to controlled or sensitive information is limited appropriately.
- How material, process, and lot traceability are maintained.
- How nonconforming products, corrective actions, and engineering changes are documented.
- How customer and regulatory requirements are communicated throughout the supplier’s own supply chain.
A supplier’s certifications and registrations are important, but buyers should also evaluate how those requirements are translated into daily processes, records, controls, and employee responsibilities.
