Understanding AS9100 and CMMC: The Compliance Challenge Facing Defense Manufacturers
Aerospace and defense manufacturers operate in an increasingly complex regulatory environment. AS9100 Rev D serves as the international quality management standard for aerospace suppliers, governing manufacturing processes, product safety, and continuous improvement. CMMC Level 2 establishes cybersecurity requirements through implementing all 110 NIST SP 800-171 controls to protect Controlled Unclassified Information (CUI).
Operating under both frameworks creates significant administrative burden when treated as separate initiatives. Document control procedures multiply. Audit schedules conflict. Training programs compete for resources. Engineering teams navigate two sets of requirements that often address the same underlying processes.
The solution lies in recognizing substantial overlap between these frameworks and building integrated management systems that satisfy both simultaneously. This approach reduces administrative overhead while strengthening both quality and security outcomes. When lives depend on the components you manufacture, neither quality nor security can be treated as secondary concerns.

What is AS9100 Rev D?
AS9100 extends ISO 9001 quality management requirements with aerospace-specific controls for the aviation, space, and defense industries. The standard emphasizes process control, risk management, and continuous improvement across manufacturing operations.
AS9100 Rev D key requirements include:
- Configuration management: Design changes affecting product conformity must be properly controlled through documented procedures
- Traceability: Materials and components require complete tracking through production processes
- Product safety: Enhanced focus on identifying and mitigating safety risks
- Counterfeit parts prevention: Specific controls to detect and prevent counterfeit components
- Risk-based thinking: Integrated risk assessment throughout all processes
What is CMMC Level 2?
CMMC Level 2 corresponds to implementing all 110 security requirements from NIST SP 800-171, designed specifically for Department of Defense contractors handling CUI. The Department of Defense estimates approximately 80,000 organizations in the Defense Industrial Base will need CMMC Level 2 certification.
CMMC Level 2 focuses on protecting sensitive information from unauthorized access and cyber threats through:
- Access controls: System permissions limited to authorized personnel based on role and clearance
- Incident response: Documented procedures for addressing security events and breaches
- System monitoring: Continuous detection of potential security incidents
- Configuration management: Baseline security configurations with formal change control
- Personnel security: Background screening and security awareness training for users accessing CUI
Overlapping Requirements: Finding Common Ground
Several critical areas exist where AS9100 and CMMC requirements intersect. Identifying these overlaps creates opportunities for process integration and operational efficiency.
Document Control and Configuration Management
AS9100 requires controlled documents with version management, approval workflows, and distribution controls. CMMC requires similar controls for documents containing CUI.
A unified document management system satisfies both requirements simultaneously. Version control mechanisms track changes across both quality documents and security-sensitive information. Access controls limit document visibility based on both role-based permissions (AS9100) and clearance levels (CMMC). Approval workflows incorporate both quality review and security classification steps.
Configuration management requirements show similar overlap. AS9100 mandates control of design changes affecting product conformity. CMMC requires configuration baselines and change control for systems processing CUI. Integrated change management processes address both simultaneously through combined impact assessment and approval procedures.
Risk Assessment and Management
Both frameworks require systematic risk assessment but focus on different risk types. AS9100 emphasizes risks to product quality, product safety, and customer satisfaction. CMMC focuses on cybersecurity risks to information assets and CUI protection.
Risk assessment integration creates a comprehensive view of organizational threats:
Risk Category | AS9100 Focus | CMMC Focus | Integrated Approach |
Design Changes | Impact on product conformity and safety | Impact on system security boundaries | Combined risk review evaluating both quality and security implications |
Supplier Management | Supplier quality and delivery performance | Supply chain cybersecurity risks | Unified supplier evaluation incorporating quality metrics and security assessments |
Process Controls | Manufacturing process risks affecting quality | Security controls for manufacturing systems | Process risk assessment considering both quality deviation and data exposure |
System Changes | Changes affecting measurement and monitoring | Configuration changes affecting security | Integrated change control board reviewing all system modifications |
Access Control and Personnel Security
AS9100 requires competency-based training and qualification for personnel performing quality-affecting work. CMMC requires personnel screening and access controls for systems handling CUI.
Training programs address both requirements through comprehensive onboarding. Quality training establishes manufacturing competencies required by AS9100. Security training covers CUI handling procedures required by CMMC. Access provisioning systems enforce both role-based quality permissions and security clearance requirements through unified identity management.
Background check requirements overlap significantly. AS9100 doesn't mandate specific screening, but aerospace customers often require it for quality-sensitive positions. Understanding the five key benefits that CMMC compliance delivers to defense contractors helps manufacturers recognize why personnel screening matters for both quality and security outcomes.
Monitoring and Measurement
AS9100 requires monitoring of manufacturing processes and product characteristics to ensure quality objectives are met. CMMC requires security monitoring to detect potential incidents and unauthorized access attempts.
Integrated monitoring systems serve both purposes through unified platforms. Manufacturing execution systems track quality metrics while also logging access to sensitive product data. Network monitoring solutions detect security events while also monitoring systems critical to quality-affecting processes. Measurement equipment calibration systems track both quality measurement devices (AS9100) and security monitoring tools (CMMC).
Building an Integrated Management System for AS9100 and CMMC Compliance
Integrated management systems can reduce implementation and maintenance costs by approximately 50% compared to separate systems. The key is deliberate design that serves both frameworks from a single foundation.
Unified Policy Structure
Create a hierarchical policy framework that establishes principles for both quality and security simultaneously. This eliminates redundant documentation while ensuring comprehensive coverage.
Policy Level | Purpose | Key Integration Points |
Top-Level Policies | Organizational commitment signed by executive leadership | Establishes commitment to both quality excellence and information protection |
Mid-Level Procedures | Specific control requirements | Quality procedures incorporate security considerations; security procedures reference quality requirements |
Work Instructions | Detailed task guidance | Combined quality and security-sensitive procedures in single documents |
Core Process Integration
Design your fundamental processes to address both frameworks simultaneously rather than creating parallel systems. This approach improves efficiency while maintaining compliance rigor.
Key processes to integrate include:
- Document Control: Enforce quality approval workflows and security classification markings through unified review procedures
- Change Management: Evaluate both quality impact and security implications before approval
- Supplier Management: Assess quality capability and cybersecurity posture through integrated evaluation criteria
- Audit Programs: Evaluate quality system effectiveness and security control implementation in combined assessments
Defense subcontractors navigating DFARS 252.204-7021 requirements alongside AS9100 standards benefit significantly from integrated management approaches that address overlapping compliance obligations.
Single-Source Documentation Approach
Maintain documentation in formats serving both purposes efficiently. Manufacturing work instructions should include quality requirements and security handling procedures in the same document. Process flow diagrams can identify both quality control points and data protection requirements through standardized notation.
Risk registers should document both quality risks and cybersecurity threats in unified tracking systems. Your corrective action system can track quality nonconformances and security incidents through common investigation and resolution procedures.
Preparing for CMMC 2.0 certification requires manufacturers to implement comprehensive cybersecurity readiness programs that complement existing AS9100 quality systems rather than operating independently.
Consolidated Audit Strategy
CMMC Level 2 requires assessment every three years while AS9100 typically requires annual surveillance audits. Combine these activities to minimize operational disruption.
Build cross-functional audit teams with both quality and security competencies through comprehensive training programs. Quality auditors should receive training on CMMC requirements relevant to manufacturing processes, while security auditors learn quality system requirements.
Develop integrated audit protocols that address both frameworks in unified assessment tools. A single interview with a document control manager can assess both quality document procedures and CUI handling protocols. This integrated approach provides clearer guidance for corrective actions while reducing audit burden by nearly half.
Maintaining Operational Efficiency Through Integration
Integration efforts must deliver measurable efficiency gains to justify the investment required for unified system development. Properly executed integration reduces operational burden while improving compliance outcomes.
Reduced Training Overhead
Integrated training programs significantly reduce time personnel spend in compliance activities. New employees complete a single onboarding that covers both quality and security requirements through a unified curriculum, while annual refresher training addresses both topics in coordinated sessions.
Role-specific training incorporates both quality competencies and security responsibilities relevant to each position:
- Engineering: Design control requirements and technical data protection in combined coursework
- Manufacturing: Production quality standards and CUI handling through integrated work instructions
- Management: Quality system oversight and security governance in unified leadership training
Understanding your organization's CMMC SPRS score and its relationship to overall cybersecurity posture helps manufacturers identify training priorities that strengthen both security compliance and quality outcomes.
Streamlined Documentation
Unified management systems reduce the total volume of documentation personnel must navigate during daily operations. Process owners maintain single procedure sets rather than separate quality and security procedures for redundant activities.
Document Type | Separate Approach | Integrated Approach | Efficiency Gain |
Process Procedures | Separate quality and security procedures for each process | Single procedures incorporating both requirements | 50% reduction in procedure count |
Work Instructions | Quality instructions plus separate security handling guides | Combined instructions with integrated controls | 40% reduction in documentation volume |
Training Materials | Separate quality and security training programs | Unified training addressing both requirements | 35% reduction in training hours |
Audit Protocols | Independent quality and security audit checklists | Integrated checklists covering both frameworks | 45% reduction in audit duration |
Optimized Resource Allocation
Integrated systems enable more efficient use of personnel and equipment across operations. Quality engineers with security training address both aspects during design reviews through unified evaluation criteria. Internal auditors with cross-functional expertise conduct combined assessments, reducing audit cycles by nearly half.
Management review processes address both quality and security performance in single executive sessions. Leadership receives integrated dashboards showing both quality metrics and security posture through unified reporting systems, improving decision-making while reducing meeting overhead.
Enhanced Compliance Outcomes
Integration often improves compliance outcomes for both frameworks through comprehensive visibility. Personnel better understand how quality and security requirements relate to their daily work when presented through integrated training and procedures.
Key benefits include:
- Holistic corrective actions that address root causes affecting both quality and security rather than treating them independently
- Comprehensive risk assessments that identify threats potentially missed in framework-specific reviews
- Unified audit findings that receive more thorough corrective actions when viewed through both quality and security lenses simultaneously
Practical Implementation Considerations for Manufacturers
Several practical factors affect successful integration of AS9100 and CMMC compliance programs.
Existing System Maturity
Organizations with mature AS9100 systems can often incorporate CMMC requirements more easily than building separate systems from the ground up. Existing quality infrastructure provides a foundation for adding security controls through systematic enhancement.
Manufacturers implementing both frameworks simultaneously have the greatest opportunity for integration success. Building unified systems from the start avoids later consolidation efforts and associated rework costs.
Organizational Structure
Companies with separate quality and security departments may face organizational challenges during integration efforts. Cross-functional teams should include representatives from both areas with executive sponsorship. Executive sponsorship helps overcome siloed thinking and resource allocation conflicts.
Smaller manufacturers often find integration easier due to fewer organizational barriers between departments. Personnel already wear multiple hats, making combined quality and security responsibilities a natural fit for existing roles.
Technology Considerations
Integrated management systems benefit from appropriate technology platforms supporting both frameworks. Quality management software with security features enables unified document control and access management. Manufacturing execution systems with audit logging serve both quality monitoring and security requirements through single platforms.
However, technology alone doesn't create integration success. Process design and organizational alignment matter more than specific tools for achieving effective integration. Start with integrated processes and select technology that supports your unified approach.
