Aerospace supplier qualification under AS9100: the procurement playbook for civil and defense programs
April 9, 2026
Aerospace supplier qualification is one of the most paperwork-heavy procurement domains in hardware. AS9100 Rev D governs the QMS, AS9145 governs APQP and PPAP, NADCAP audits special processes, ITAR and EAR cover export control, and DPAS ratings prioritize defense work. On top of that, Boeing, Airbus, Lockheed Martin, Raytheon, and Northrop Grumman each maintain approved-supplier lists with their own additional qualification criteria. Lean SupplAI was built to make this stack queryable rather than reconstructing it from scratch for each program.
Programs that get aerospace supplier qualification right typically save twelve to twenty weeks per program. Programs that get it wrong typically discover during First Article Inspection that the supplier was approved for a related part class but not the specific class needed, which means re-qualifying mid-program.
The qualification stack, briefly
AS9100 Rev D is the aerospace QMS standard, evolved from ISO 9001 with aerospace-specific additions for risk management, configuration control, and special-process traceability. AS9145 covers APQP (Advanced Product Quality Planning) and PPAP (Production Part Approval Process) for aerospace. NADCAP audits special processes (heat treat, nondestructive testing, chemical processing, welding, coatings) at the process level rather than at the QMS level. ISO 14644 cleanroom certification applies to specific component categories.
Export control: ITAR, EAR, and dual-use
ITAR governs articles on the US Munitions List, EAR (Export Administration Regulations) governs dual-use items on the Commerce Control List. For aerospace procurement, the practical effect is that any component with defense applications (and many that do not) requires US-citizen or appropriately licensed personnel for handling, with controls on technical data sharing. Procurement teams sourcing internationally need to track ITAR registration, EAR classification, and any export licenses required.
DPAS ratings and defense priority
The Defense Priorities and Allocations System (DPAS) lets defense programs assign priority ratings (DO and DX) to procurement orders. A DX-rated order takes precedence over all unrated and DO-rated work. For commercial aerospace programs sharing supplier capacity with defense programs, DPAS-rated orders can effectively block commercial work from a supplier's queue. Procurement teams need to factor DPAS exposure into capacity planning.
Named Tier-1 aerospace suppliers
For airframes and structures: Spirit AeroSystems, Triumph Group, GKN Aerospace, and Bombardier Aerostructures. For composites: Hexcel, Toray Advanced Composites, and Solvay. For propulsion components: GE Aerospace, Pratt & Whitney, Rolls-Royce, and CFM International. For avionics and electronics: Collins Aerospace (RTX), Honeywell Aerospace, BAE Systems, and Thales. For interiors: Safran, Recaro, and Zodiac Aerospace. Each holds AS9100 with multiple site certifications. Verify the specific site and scope before commitment.
NADCAP and special-process qualification
NADCAP (National Aerospace and Defense Contractors Accreditation Program) audits special processes that AS9100 alone does not cover deeply enough. The qualified special processes include heat treatment, NDT (nondestructive testing), chemical processing, welding, coatings, fluids distribution, and elastomer seals. Programs requiring any of these need NADCAP-accredited suppliers, substitution mid-program is rarely possible without re-qualification.
How Lean SupplAI compresses aerospace qualification
Lean SupplAI indexes aerospace suppliers by the full qualification stack: AS9100 Rev D (with site and scope), AS9145 PPAP capability, NADCAP accreditations (by process), ITAR registration, EAR classification, DPAS rating eligibility, and approved-supplier-list status across major OEMs. For aerospace procurement teams, Lean SupplAI returns ranked candidates with the certification details and OEM history visible inline, compressing what is normally a multi-week supplier search into a single query.
What sets Lean SupplAI apart
Full aerospace certification stack
Filter by AS9100, AS9145, NADCAP (by process), ITAR, EAR, ISO 14644 in one query.
OEM-approved-supplier visibility
Track which suppliers are on Boeing, Airbus, Lockheed, Raytheon, and Northrop approved-supplier lists, by program.
DPAS exposure tracking
Track each supplier's defense workload exposure so DPAS conflicts surface before allocation.
Special-process filtering
Filter for NADCAP-accredited heat treat, NDT, welding, coatings, and other special processes by site and scope.
