🔥 NADCAP
NADCAP-Accredited Special Process Suppliers in Jacksonville, FL
NADCAP accreditation is where aerospace sourcing gets specific, because it certifies the special processes that quality-system certificates leave untouched. In Jacksonville, where naval aviation maintenance and aerospace machining drive demand, knowing how to verify a NADCAP scope for heat treating, welding, nondestructive testing, or coatings is what keeps a part from being rejected at source inspection. This guide breaks down what NADCAP covers and how a buyer maps and verifies the special-process chain locally.

What NADCAP Accredits and Why It Is Separate
NADCAP, administered by the Performance Review Institute on behalf of the aerospace industry, accredits special processes rather than whole shops or quality systems. Special processes are those whose results cannot be fully verified by inspecting the finished part. You cannot look at a heat-treated bracket and see whether the metallurgy is correct, and you cannot confirm a weld's internal integrity or a coating's adhesion by eye. Because the proof is in the process, the industry accredits the process itself.
The NADCAP catalog spans the processes that recur on Jacksonville aerospace and defense hardware: heat treating, welding and brazing, chemical processing such as anodizing and passivation, nondestructive testing including penetrant, magnetic particle, radiographic, and ultrasonic methods, surface coatings, and more. Each is accredited to specific industry and prime specifications, and accreditation is granted to a particular facility for a particular scope.
This is why NADCAP sits alongside, not inside, AS9100. AS9100 governs the overall quality management system, but it explicitly does not certify special-process competence. A part can pass through an impeccable AS9100 machine shop and still fail if its heat treat or NDT was performed by a processor lacking the right NADCAP accreditation. Treating the two as separate is the foundation of correct aerospace sourcing.
Reading a NADCAP Scope the Way an Auditor Would
A NADCAP accreditation is not a single yes-or-no badge; it is a scope, and the scope is everything. A heat-treat processor accredited for one alloy family and furnace type may not be accredited for the specific heat treatment your part requires. An NDT house accredited for penetrant and magnetic particle inspection may not hold radiographic accreditation. The buyer's job is to match the processor's exact accredited scope to the exact process and specification called out on the part.
Verification runs through the PRI's eAuditNet system, the database where NADCAP accreditations are recorded. There you can confirm a Jacksonville supplier's accreditation is current and read which commodities and specifications it covers. Match the accredited specifications against your part's process call-outs line by line. A mismatch here is the single most common reason aerospace parts get rejected at source inspection after appearing perfectly machined.
Also confirm currency. NADCAP accreditation runs on audit cycles, and a lapsed or suspended accreditation means the processor is not authorized for that work today even if it was last year. A disciplined buyer rechecks eAuditNet status before each program, not just once, because a supplier's accreditation status can change between jobs.
Mapping the Special-Process Chain for a Jacksonville Part
Most aerospace parts move through several special processes, and the buyer who maps the full chain up front avoids painful surprises. A typical flow for a machined aerospace component might run machining, then heat treat, then nondestructive testing, then a surface coating or chemical conversion, then final inspection. Each special-process step needs the correct NADCAP accreditation at the facility performing it, and those facilities are frequently different companies.
In Jacksonville's supply base, an AS9100 machine shop often coordinates this chain on the buyer's behalf, routing parts to NADCAP-accredited heat treaters, NDT houses, and finishing processors. That coordination is valuable, but it does not relieve the buyer of due diligence. You should know who performs each special process, confirm each holds the right NADCAP scope, and require that the special-process certifications return with the parts.
Lead time and logistics live inside this chain. Each transfer between the machine shop and a special-process house adds transit and queue time, and a single accreditation gap can stall the whole flow. Mapping the chain early, confirming each processor's eAuditNet status, and lining up alternates for critical steps is the difference between a program that flows and one that stalls at the worst moment.
Frequently Asked Questions
Yes, in almost all aerospace cases, because AS9100 and NADCAP cover fundamentally different things. AS9100 certifies a shop's overall quality management system, including configuration control, risk management, and counterfeit-part prevention, but it explicitly does not certify special-process competence. Special processes such as heat treating, welding, anodizing, passivation, and nondestructive testing produce results that cannot be fully verified by inspecting the finished part, so the aerospace industry accredits those processes separately under NADCAP. A part can move through an impeccable AS9100 machine shop in Jacksonville and still fail if its heat treat or NDT was performed by a processor that lacks the correct NADCAP accreditation for that specific process and specification. Prime flow-down requirements almost always demand NADCAP accreditation on the relevant special processes regardless of who performs them. So when you source an AS9100 machining job, identify every special process the part requires, confirm whether the shop performs any of them in-house under its own NADCAP accreditation, and verify that each subcontracted processor holds the right NADCAP scope. The two credentials work together; neither substitutes for the other.
NADCAP accreditations are recorded in eAuditNet, the database administered by the Performance Review Institute, which manages NADCAP on behalf of the aerospace industry. Rather than accepting a certificate image, look the supplier up in eAuditNet to confirm the accreditation is current and to read the exact scope. The scope is the critical detail, because NADCAP is accredited per facility for specific commodities and specifications, not as a blanket pass. A heat-treat processor accredited for one alloy family and furnace type may not cover the heat treatment your part requires, and an NDT house accredited for penetrant and magnetic particle inspection may not hold radiographic or ultrasonic accreditation. Match the accredited specifications against your part's process call-outs line by line, since a scope mismatch is the most common reason aerospace parts are rejected at source inspection despite looking perfectly made. Also confirm currency, because NADCAP runs on audit cycles and a lapsed or suspended accreditation means the processor is not authorized today even if it was last year. Recheck status before each program rather than relying on a one-time verification, since accreditation status can change between jobs.
The processes that recur on Jacksonville's naval aviation and aerospace hardware map closely to the core NADCAP commodity areas. Heat treating is among the most common, since flight-critical metals require controlled metallurgy that cannot be confirmed by visual inspection. Welding and brazing are frequent on structural and engine-adjacent components and demand qualified procedures and accredited process control. Chemical processing such as anodizing, passivation, and chemical conversion coatings is routine for corrosion protection, especially relevant in a coastal, salt-air environment like Northeast Florida. Nondestructive testing is nearly universal on critical parts and spans penetrant, magnetic particle, radiographic, and ultrasonic methods, each accredited separately. Surface coatings and certain finishing operations round out the common list. Each of these is accredited to specific industry and prime specifications at a particular facility, so the relevant NADCAP scope depends on exactly which specifications your part calls out. When mapping a part's process chain, identify every special-process step, determine which NADCAP commodity covers it, and confirm the performing facility holds the matching accreditation before parts begin flowing through the chain.
Significantly, because most aerospace parts pass through several special processes performed at different facilities, and each transfer adds time. A representative flow for a machined aerospace component might run machining, then heat treat, then nondestructive testing, then a surface coating or chemical conversion, then final inspection, with the special-process steps often handled by separate NADCAP-accredited companies. Every handoff between the machine shop and a special-process house introduces transit time plus the processor's own queue, and those queues can be substantial when a NADCAP-accredited heat treater or NDT house is serving many aerospace customers at once. A single accreditation gap or a processor at capacity can stall the entire chain. In Jacksonville, an AS9100 machine shop frequently coordinates this routing on the buyer's behalf, which helps, but the buyer should still map the full chain up front, confirm each processor's eAuditNet status, and where possible line up alternate accredited processors for the most critical or capacity-constrained steps. Building this map early, rather than discovering the chain mid-program, is the difference between a job that flows predictably and one that stalls at the worst possible moment under schedule pressure.
