Aerospace & Defense Manufacturing Partners You Can Trust

AS9100 is the aerospace and defense supplement to ISO 9001, and it's mandatory for any shop wanting to supply the industry. Beyond standard quality management, AS9100 adds requirements for configuration management (tracking engineering changes), product safety and traceability, foreign object debris (FOD) control, and counterfeit parts prevention. Shops must maintain a documented configuration management system that ties every manufactured part to its specific engineering revision, material specification, and process parameters. This means your supplier maintains detailed work instructions, process specifications, and traveler documentation for every part number. FOD control is particularly critical in shops producing components for flight-critical systems. Machining debris, tool fragments, and even swarf can cause catastrophic failures if left in a casting cavity or hydraulic passage. AS9100-certified shops implement controlled environments, magnetic chip traps, tool breakage detection, and final inspection protocols specifically designed to eliminate FOD. When you source a precision-machined engine mount or fuel manifold, your supplier's AS9100 registration is proof they understand these risks and have implemented systematic controls. On ManufacturingBase, filtering by AS9100 certification instantly narrows results to shops that have passed independent audits and maintain continuous compliance. This saves procurement teams weeks of vetting work. You can also see certification expiration dates and scope (what product categories and processes are certified), so you know whether a shop's AS9100 covers the specific work you need.

ITAR stands for International Traffic in Arms Regulations, a State Department export control regime that governs the design, manufacture, and export of defense articles and related technical data. If your manufacturing partner touches any ITAR-controlled item—which includes most aerospace and defense components—they must comply or you create severe compliance exposure for your company. ITAR violations are federal crimes with potential prison time and fines exceeding $500,000 per violation. This is not theoretical; the Commerce and State Departments actively pursue ITAR cases. ITAR-compliant manufacturers must implement facility security plans, visitor logs, employee clearances, and data segregation protocols. Technical data (drawings, process specs, supplier lists, test results) must be physically and electronically secured. Subcontracting relationships must be approved in advance—a shop cannot simply forward ITAR data to a supplier without explicit authorization and ITAR compliance verification. Many shops implement "ITAR-controlled areas" within their facilities with badge access, secured file systems, and restricted personnel lists. Employees handling ITAR data often must complete annual training and background checks. When sourcing through ManufacturingBase, you can filter for ITAR-capable shops and confirm their compliance status directly in the platform. This transparency prevents the common procurement mistake of discovering ITAR compliance issues mid-project, which can stall your supply chain and create legal exposure.

NADCAP (National Aerospace and Defense Contractors Accreditation Program) is an industry-managed accreditation system for critical aerospace processes. While AS9100 covers general quality management, NADCAP dives deep into specialized areas: heat treat, surface treatment, welding, composite processing, NDT, calibration, and manufacturing. If you're sourcing a titanium landing gear component that requires precise heat treat to achieve specific mechanical properties, you want a supplier with NADCAP heat treat accreditation. An AS9100-certified shop without NADCAP heat treat accreditation may have quality systems in place, but they haven't passed the specialized audit that proves they can control temperature uniformity, atmosphere control, and quench protocols to aerospace tolerances. NADCAP audits are conducted by third-party accreditors and focus on the specific equipment, procedures, and personnel qualifications for each process. A shop might be NADCAP-accredited for aluminum heat treat but not for stainless steel, or accredited for TIG welding but not MIG. This specificity matters because your purchasing team needs to know exactly which processes at which supplier are qualified for your critical components. Mil-spec and customer-specific requirements often mandate NADCAP accreditation for heat treat, welding, NDT, and surface treatment, making it a practical requirement rather than a nice-to-have. On ManufacturingBase, NADCAP scope is clearly listed alongside NADCAP accreditation status, so you can immediately confirm whether a shop is qualified for your specific process requirements.

Aerospace and defense supply chains face an ongoing threat from counterfeit and out-of-spec materials. A titanium alloy sold as Ti-6-4 might actually be a cheaper titanium variant, or aluminum might have been diverted from a rejected batch. The consequences are severe: component failure in service, potential loss of life, and regulatory investigations. The Department of Defense and FAA have documented cases of counterfeit fasteners, bearings, and raw materials entering the supply chain, some traced back to disreputable recyclers and grey-market distributors. Manufacturers qualified for aerospace work implement strict material control procedures. Raw materials arrive with mill certs (test reports showing chemical composition and mechanical properties) and lot identification. The supplier logs material into a controlled inventory system, maintains certs alongside physical stock, and tracks consumption through work orders. Before production, incoming material inspection verifies dimensions, surface condition, and sometimes spot checks hardness or other properties. Documentation ties every finished part back to its raw material lot, heat treat batch, and inspection records. This full traceability chain is essential for field service bulletins, recalls, and failure investigations. When a supplier is AS9100 and NADCAP accredited, these material control systems are not aspirational—they're audited and verified. ManufacturingBase helps you identify suppliers with proven material traceability practices, reducing your risk of counterfeit exposure and simplifying your own compliance documentation.

First-Article Inspection is a formal process where the first part or small batch produced to a new design is subjected to 100% dimensional inspection, material verification, and sometimes destructive testing. FAI reports document that the supplier's tooling, processes, and materials can meet the engineering specification. Until FAI is approved, production cannot be released. This creates a natural delay in aerospace manufacturing—typically 2-4 weeks for FAI completion and approval—but it's a critical gate that prevents systemic non-conformances from appearing across an entire production run. FAI is governed by AS9102, a standard that defines the reporting format and required documentation. The supplier measures every critical dimension, documents material certs, photographs tooling, and provides process parameter records. If metallurgical properties are critical, they may sacrifice a sample part for destructive testing (tensile, hardness, microstructure). The customer (or a customer-approved inspection lab) reviews the FAI report and either approves production or requests rework and re-inspection. For complex assemblies, FAI may include functional testing and vibration analysis. The entire process requires meticulous documentation and often adds 4-8 weeks to initial delivery timelines. Finding a supplier experienced in FAI management is important. Some smaller shops have limited FAI experience and underestimate the documentation rigor required. Aerospace-experienced suppliers on ManufacturingBase understand FAI requirements and can provide realistic lead time estimates that account for inspection gates and approval cycles.
