What This Post Covers
The Cybersecurity Maturity Model Certification (CMMC) creates specific obligations for aerospace manufacturers operating in the defense supply chain. Tier 2 and Tier 3 suppliers, who form the backbone of aerospace manufacturing, face increasing pressure to achieve CMMC Level 2 certification as prime contractors flow down security requirements through their supply chains.
Aerospace manufacturers handle some of the most sensitive Controlled Unclassified Information (CUI) in the defense industrial base. Technical drawings, manufacturing process specifications, inspection records, and engineering change proposals all constitute CUI that requires protection under NIST SP 800-171 controls, which form the basis of CMMC Level 2 requirements.
The November 2026 implementation deadline for CMMC Level 2 creates urgency for aerospace suppliers. Prime contractors including Boeing, Lockheed Martin, Northrop Grumman, Raytheon, and General Dynamics have already begun requiring CMMC certification from their Tier 2 and Tier 3 suppliers, making compliance a business survival requirement for companies seeking to maintain defense contracts.
Aerospace manufacturing involves handling multiple categories of CUI that require robust protection. Technical drawings and CAD files contain detailed specifications for aircraft components, tooling, and assembly processes. These files often reveal proprietary manufacturing techniques and design intellectual property that could compromise national security if disclosed.
Manufacturing plans and process specifications define how aerospace components are produced, including material specifications, machining parameters, heat treatment processes, and quality control requirements. Under FAA regulations, certain data categories such as Part 21 (aircraft certification) and Part 25 (transport category aircraft) data are treated as CUI and must be protected accordingly.
Inspection records, including dimensional inspection reports and first article inspection data, document that aerospace components meet required specifications. Materials traceability records track the origin and processing history of materials used in aircraft construction, a critical requirement for FAA compliance and liability management.
The International Traffic in Arms Regulations (ITAR) and DFARS 252.204-7012 both require protection of this technical data, creating overlapping compliance obligations that aerospace manufacturers must address. The NADCAP accreditation program, which certifies special processes in aerospace manufacturing, also involves handling CUI that must be protected under CMMC requirements.
AS9100 revision D is the quality management system standard required for virtually all aerospace defense contractors. This standard, which builds on ISO 9001 with additional aerospace-specific requirements, serves as a prerequisite for working with major primes and is often the first certification aerospace manufacturers obtain when entering the defense market.
The overlap between AS9100D and CMMC requirements creates both efficiencies and challenges. AS9100D already requires documented processes for configuration management, risk management, and supplier management, all areas that align with NIST SP 800-171 controls. Companies with mature AS9100 implementations often have foundational elements that support CMMC compliance.
However, AS9100D focuses on quality management rather than information security. While AS9100 addresses some security-related topics such as product protection and counterfeits prevention, it does not comprehensively address the 110 controls in NIST SP 800-171. Aerospace manufacturers must recognize that AS9100 certification alone does not satisfy CMMC requirements.
Additional aerospace standards including AS9110 (aerospace maintenance organizations) and AS9120 (aerospace distributors) similarly provide quality frameworks but do not replace CMMC compliance obligations. Companies holding these certifications should use them as a foundation while implementing additional security controls required by CMMC Level 2.
Aerospace manufacturers frequently exhibit specific gaps when assessed against CMMC requirements. Asset inventory and configuration management for CAD workstations represents a common challenge, as engineering departments often operate with minimal tracking of the computers and software used to create and store technical drawings.
Media sanitization processes for released drawings present another significant gap. When engineering change proposals are approved and drawings are released for production, organizations must have documented procedures for sanitizing media and controlling the flow of finalized technical data. Many aerospace suppliers lack formal processes for this critical control.
Access control for engineering change proposals requires implementation of role-based access controls and audit logging for systems containing CUI. Aerospace manufacturers often struggle to demonstrate who accessed specific design data and what changes were made, a requirement under NIST SP 800-171 access control and audit family controls.
Fifteen of the 110 NIST SP 800-171 controls are designated as "fenced" or exclusive to CUI, meaning they only apply when organizations actually handle CUI. For aerospace manufacturers, determining which systems contain CUI and ensuring those systems receive additional protections requires careful analysis of data flows throughout the organization.
The Cyber Grants Alliance national CMMC Gap Assessment Grant program provides $5,000 in-kind assessments to qualifying aerospace suppliers. This program is designed to help Tier 2 and Tier 3 aerospace manufacturers understand their current compliance posture against all 110 NIST SP 800-171 security controls.
Each gap assessment grant includes comprehensive evaluation of technical infrastructure, policies, procedures, and operational practices specific to aerospace manufacturing environments. Recipients receive detailed gap identification with prioritization by severity, giving contractors a complete picture of their CMMC readiness status and a roadmap for remediation activities.
The gap assessment grant program is sponsored by CMMC Ready Now and delivered through qualified cybersecurity professionals with experience in aerospace manufacturing environments. Aerospace contractors can apply online with applications reviewed on a rolling basis until all 100 grants are awarded.
For aerospace suppliers, this grant provides particular value given the complexity of CUI handling in manufacturing environments. The assessment addresses the unique challenges of protecting technical data on manufacturing floors, securing CAD workstations, and implementing access controls for engineering systems.
Aerospace manufacturers interested in CMMC gap assessment grants should first review their current data handling practices to identify whether they process CUI in the form of technical drawings, manufacturing specifications, inspection records, or materials traceability data. Companies that handle any of these data types should strongly consider applying for a gap assessment.
For immediate assistance with CMMC gap assessment, aerospace defense contractors can apply for the national grant program at https://www.cybergrantsalliance.org/cmmc-gap-assessment-grant. This program provides professional evaluation services to help contractors prepare for CMMC certification requirements.
Aerospace suppliers should also explore the State Grants hub at https://cybergrantsalliance.org/state-grants for additional programs that may be available. While CMMC requirements are national in scope, certain states offer programs specifically supporting aerospace and defense manufacturing sectors.
