FAA 14 CFR Part 21 and PMA Requirements

FAA 14 CFR Part 21 Subpart K prescribes procedural requirements for issuing Parts Manufacturer Approvals (PMAs) and sets ongoing obligations for PMA holders. Under §21.303, PMA applicants submit design data such as drawings, specifications, dimensions, materials, and processes, along with test reports that demonstrate airworthiness compliance.

The regulation also requires inspections and tests that confirm compliance, verify materials, validate conformity, and control manufacturing processes.

Subpart K specifically governs PMA requirements and ties design control directly to production quality. Section 21.307 requires each PMA applicant or holder to establish a quality system that meets §21.137, and §21.311 requires that PMA articles conform to the approved type design and be manufactured under that quality system.

PMA Compliance Checklist:

• Production approvals supported by complete design data submission per §21.303

• AS9102 First Article Inspection that proves conformity to the approved design on initial production runs

• Quality manual per §21.308 that describes the quality system in an FAA-acceptable format

• FAA inspection readiness per §21.310 for both quality systems and manufactured articles

• 8130-3 Authorized Release Certificate issued for airworthiness approval of each applicable part

Precision Advanced Manufacturing uses multi-axis CNC machining with full lot control and documentation so PMA parts ship with the traceability and records auditors expect.

AS9100D Quality Management and the IA9100 Transition

AS9100D builds on ISO 9001:2015 with 105 aerospace-specific requirements that target product safety, counterfeit parts prevention, configuration management, and traceability. The International Aerospace Quality Group (IAQG) plans a transition to IA9100 beginning in late 2026, which will strengthen risk-based thinking, cybersecurity, and product safety expectations across the supply chain.

Key AS9100D clauses address risk management integration, configuration management for design changes, and structured First Article Inspection using AS9102. IA9100 Stage 1, launching in January 2026, elevates product safety to a mandatory requirement with documented risk assessments and applies stricter counterfeit part controls through enhanced verification protocols.

AS9100D Implementation Checklist:

• Risk management is embedded in quality planning and product realization activities

• FOD prevention programs with documented controls, housekeeping standards, and training

• Statistical Process Control (SPC) and Measurement System Analysis (MSA) for key characteristics

• Configuration management that tracks and approves design and manufacturing changes

• Counterfeit parts prevention with supplier verification and incoming inspection protocols

Precision Advanced Manufacturing maintains AS9100D registration and ISO 9001 certification to support zero-defect delivery, scalable production, and detailed traceability from prototype through full-rate manufacturing.

ITAR and CMMC 2.0 for Aerospace Programs

The U.S. Department of State’s Directorate of Defense Trade Controls (DDTC) published final ITAR revisions on August 27, 2025, effective September 15, 2025, revising 15 of 21 United States Munitions List (USML) categories.

These changes remove some items from USML control and add advanced parts that support new military platforms. Companies that manufacture defense articles must register with DDTC, and face civil penalties up to $1,271,078 per violation and criminal penalties up to 20 years imprisonment for willful violations.

The DoD’s final CMMC 2.0 rule (32 CFR Final Rule, effective December 2024) makes cybersecurity certification a condition for all Department of Defense contracts and defines three maturity levels aligned with NIST SP 800-171 Revision 2. Phase 2, from November 10, 2026, through November 9, 2027, expands requirements to include third-party C3PAO assessments for many Level 2 contracts.

ITAR/CMMC Compliance Checklist:

• DDTC registration covering defense article manufacturing and export activities

• Technical data controls that prevent unauthorized export or access by foreign nationals

• CMMC Level 2 certification implementing all 110 NIST SP 800-171 controls

• Supplier flow-down clauses for subcontractors that handle Controlled Unclassified Information (CUI)

• SPRS reporting with current and accurate assessment scores

Precision Advanced Manufacturing operates fully ITAR-registered systems and applies structured supplier oversight, so DoD and space customers can reduce program risk.

Request a quote for controlled aerospace components that must meet ITAR and CMMC expectations.

NADCAP and Control of Special Processes

NADCAP accreditation focuses on special processes in aerospace and defense manufacturing, including heat treating, welding, nondestructive testing (NDT), chemical processing, and more than 20 other critical operations that inspectors cannot fully verify by final inspection alone.

NADCAP auditors average over 30 years of aerospace industry experience and evaluate process controls, equipment calibration, personnel qualifications, material traceability, and corrective action systems.

NADCAP Readiness Checklist:

• Process documentation with written procedures that match actual shop-floor practice

• Equipment calibration against traceable standards with current records

• Personnel training supported by documented competencies and periodic requalification

• Material traceability that maintains complete chain-of-custody documentation

• FOD prevention is built into special process controls and work instructions

Precision Advanced Manufacturing applies distortion-controlled welding, precision CNC machining, and sheet metal fabrication with disciplined process control for safety-critical aerospace applications.

Operational Essentials: Traceability, FOD, and Audit Readiness

Complete material traceability from raw material to final delivery depends on integrated lot control, material certifications, AS9102 First Article Inspection documentation, and FAA 8130-3 Authorized Release Certificates. FOD prevention programs must cover material handling, work environment controls, tool accountability, and personnel training across every manufacturing step.

The table below connects these operational requirements to practical implementation tasks and shows how Precision Advanced Manufacturing closes common gaps.

Requirement	Description	Implementation	Precision AM Solution
Material Traceability	Raw material to final part tracking	Lot control systems, material certs	Complete documentation and traceability
FOD Prevention	Foreign object debris elimination	Clean room protocols, tool control	One-roof finishing that reduces transfer-related FOD
8130-3 Tagging	Airworthiness release certification	FAA-authorized personnel, dual tags	Full documentation and release capability

Precision Advanced Manufacturing combines kitting and finishing in a single facility, which reduces handling steps and lowers FOD risk compared with multi-vendor processing.

2026 Compliance Roadmap and Common Pitfalls

Step-by-Step Implementation:

1. Assess regulatory applicability based on contract requirements and data handling, which defines the specific standards and certifications your program must meet.

2. Vet suppliers for AS9100D, ITAR, and CMMC certifications that align with your applicability assessment so every partner can support the required controls.

3. Implement flow-down requirements across the supply chain to contractually bind suppliers to the standards identified in the first two steps.

4. Conduct readiness audits to verify flow-down compliance and correct gaps before you scale production volumes.

Common Pitfalls to Avoid:

• Outdated CMMC assessments, because Phase 2 requires current C3PAO certification for many awards

• Incomplete traceability, where missing material certifications or records trigger audit findings

• Multi-vendor coordination gaps, where misaligned certifications and procedures create compliance risk

Precision Advanced Manufacturing provides single-source accountability through unified quality, export control, and cybersecurity frameworks so complex aerospace programs avoid these coordination issues.

How do CMMC 2.0 requirements flow down to aerospace subcontractors?

Under 32 CFR § 170.23, prime contractors must identify subcontractors handling Federal Contract Information (FCI) or Controlled Unclassified Information (CUI) and contractually flow down the appropriate CMMC certification level.

Major aerospace primes, including Boeing, Lockheed Martin, and RTX, are enforcing these requirements through supplier communications and contract modifications. Subcontractors must achieve the specified CMMC level (1, 2, or 3) as a condition of contract award, with Level 2 requiring 110 NIST SP 800-171 controls and C3PAO assessments beginning in Phase 2 (November 2026).

What documentation is required for complete aerospace parts traceability?

Complete aerospace parts traceability requires material certifications from raw material suppliers, lot control documentation throughout manufacturing, AS9102 First Article Inspection reports, in-process inspection records, final inspection documentation, and FAA 8130-3 Authorized Release Certificates for airworthiness approval.

Additional requirements include heat treatment certifications for applicable processes, special process certifications (welding, NDT, chemical processing), configuration management records for any design changes, and supplier quality documentation for all purchased materials and services.

How can aerospace manufacturers prepare for NADCAP accreditation?

NADCAP preparation requires establishing documented process controls with written procedures, implementing equipment calibration and maintenance programs against traceable standards, developing personnel qualification and training systems with ongoing competency records, creating comprehensive material traceability and control systems, and establishing robust nonconformance handling and corrective action procedures.

The initial certification process typically takes 3-6 months, depending on readiness, with costs ranging from $15,000 to $50,000 or more based on the number of processes and company size. Organizations should focus on the consistent implementation of documented procedures because discrepancies between paperwork and practice are the most common reason for audit failures.
