| CMMC 2.0 Cybersecurity | DoD contractors handling CUI | 110 NIST SP 800-171 controls, C3PAO assessment | Phase 2 November 2026 |
These regulations form an integrated compliance framework that requires coordinated implementation across quality management, cybersecurity, and export control domains. Because no single certification satisfies all requirements, successful aerospace suppliers must demonstrate simultaneous adherence to multiple standards through documented processes, certified systems, and continuous monitoring. Precision Advanced Manufacturing’s comprehensive certification portfolio addresses this multi-framework challenge through established AS9100D quality systems, ITAR registration, and scalable production capabilities that support both prototype and full-rate manufacturing programs.
Of these four regulatory frameworks, FAA Part 21 establishes the foundation for aerospace parts manufacturing by defining the airworthiness certification process that all other compliance efforts must support.
FAA 14 CFR Part 21 and PMA Essentials
Subpart K of 14 CFR Part 21 applies to Parts Manufacturing Approval (PMA) and governs certification of replacement and modification parts for type-certificated aircraft. The PMA process requires comprehensive data submission, testing validation, and ongoing quality system maintenance that demonstrate compliance with applicable airworthiness standards.
Essential PMA compliance steps include:
- Submit FAA Form 8110-12B to establish the certification basis.
- Provide design data that demonstrate compliance with airworthiness standards.
- Conduct required testing per applicable Technical Standard Orders (TSO).
- Establish a quality system that meets FAA production approval requirements.
- Implement 8130-3 Authorized Release Certificate procedures.
- Maintain PMA database registration and EASA bilateral agreement compliance.
- Document traceability from raw materials through final inspection.
The amendments to Part 21 strengthen quality system requirements and clarify documentation standards for PMA holders. Precision Advanced Manufacturing’s AS9100D-certified quality systems support PMA-compliant traceability through integrated material control, process validation, and inspection documentation that meet FAA production approval standards.
AS9100D Quality Management and AS9102 FAI Requirements
AS9100D enhances ISO 9001:2015 with over 100 aerospace-specific requirements that address operational risk management, configuration management, product safety analysis, and counterfeit parts prevention. The forthcoming IA9100 standard, expected for late 2026 release, will replace AS9100D with enhanced cybersecurity requirements, ethics programs, and stronger APQP integration.
Key AS9100D aerospace enhancements beyond ISO 9001 include:
- Risk-based thinking with defined operational risk management processes.
- Foreign Object Debris (FOD) prevention and control programs.
- Configuration management for design and production changes.
- Product safety analysis and critical item identification.
- Counterfeit parts prevention through supplier controls.
AS9102 First Article Inspection (FAI) requirements mandate comprehensive validation of new or changed manufacturing processes. IA9145 defines PPAP elements, distinguishes mandatory versus optional deliverables, and integrates Measurement Systems Analysis (MSA) as a requirement.
Essential FAI deliverables include:
- Ballooned production drawings with inspection results.
- FAI reports documenting verification of all characteristics.
- Material certifications and test reports.
- Functional test results where applicable.
Precision Advanced Manufacturing’s certified AS9100D systems reduce rework and audit findings through rigorous process controls, comprehensive FAI procedures, and integrated quality planning that support first-time compliance with aerospace quality standards.
While AS9100D governs quality management, defense and space applications add two additional compliance layers: export controls under ITAR and cybersecurity requirements under CMMC 2.0.
ITAR and CMMC 2.0 for Defense and Space Parts
ITAR controls defense articles and technical data on the United States Munitions List (USML) and requires DDTC registration while restricting access to U.S. persons unless authorized. September 2025 USML revisions transferred selected items to EAR jurisdiction and added controls on items that reflect technological advancements.
ITAR compliance fundamentals include:
- DDTC registration for manufacturers of USML defense articles.
- Access controls that limit technical data to authorized U.S. persons.
- Export licensing for international transfers of controlled items.
- Deemed export controls for foreign person access within the United States.
- Recordkeeping requirements per ITAR §122.5.
CMMC 2.0 Level 2 requires implementation of 110 NIST SP 800-171 controls for contractors handling Controlled Unclassified Information (CUI). Phase 2 enforcement beginning November 2026 mandates C3PAO assessments for new DoD contracts involving CUI.
The 110 NIST SP 800-171 controls span multiple security domains, and each domain requires specific technical implementations and infrastructure investments:
| CMMC 2.0 Domain | Control Examples | Implementation Requirements | 2026 Deadline |
|---|---|---|---|
| Access Control | Multi-factor authentication, least privilege | Identity management systems | November 2026 |
| System Protection | Encryption, network segmentation | Secure IT infrastructure | November 2026 |
| Audit and Accountability | Logging, monitoring, incident response | SIEM and documentation systems | November 2026 |
Precision Advanced Manufacturing’s ITAR registration and cybersecurity controls address DoD compliance requirements through secure facilities, U.S. persons access restrictions, and documented export control procedures that protect sensitive defense and aerospace technical data.
Beyond regulatory compliance frameworks, aerospace manufacturers must also demonstrate operational excellence in special processes, material control, and contamination prevention, and NADCAP accreditation provides industry-recognized validation in these areas.
NADCAP, Traceability, FOD, and Special Processes
NADCAP (National Aerospace and Defense Contractors Accreditation Program) provides industry-managed accreditation for special processes including welding, heat treatment, non-destructive testing, and chemical processing. NADCAP accreditation demonstrates process capability and quality system maturity required by major aerospace OEMs.
Achieving and maintaining NADCAP accreditation requires manufacturers to implement rigorous operational controls across material handling, process execution, and contamination prevention. Critical operational requirements include:
- Complete material traceability from mill certifications through final delivery.
- Lot control and segregation procedures for different material grades.
- Foreign Object Debris (FOD) prevention programs with training and audits.
- 8130-3 Authorized Release Certificate procedures for airworthy parts.
- Special process controls that meet NADCAP requirements.
- Calibrated measurement systems with MSA validation.
- Environmental controls for critical manufacturing processes.
- Change control procedures for design and process modifications.
Traceability documentation must include material certifications, process records, inspection results, and handling history that demonstrate compliance with aerospace quality standards. FOD programs require systematic prevention measures, employee training, and regular facility audits that reduce contamination risks.
