NADCAP Accredited Special Process Suppliers in Fort Lauderdale, FL
AS9100 tells you a Fort Lauderdale machine shop runs an aerospace quality system, but it says nothing about whether the heat treat, anodize, or nondestructive testing on your part meets aerospace standards, that is what NADCAP accredits. For flight and defense hardware sourced through South Florida, the special-process chain is often where quality risk actually lives, and NADCAP is the mechanism that audits those processes against industry consensus requirements. This page covers how Fort Lauderdale buyers verify NADCAP scope, why it matters, and how it fits into the broader sourcing chain.

The Special-Process Gap NADCAP Fills
Special processes are operations whose results cannot be fully verified by inspecting the finished part, you can't measure your way to confidence that a heat treat hit the right metallurgical structure or that an anodize coating has the correct thickness and adhesion throughout. Heat treating, chemical processing, coatings, welding and brazing, nondestructive testing, and chemical milling all fall into this category. For aerospace and defense, getting these wrong can cause latent failures that don't show up until the part is in service.
NADCAP, administered by the Performance Review Institute, accredits these special processes against industry-consensus checklists developed with primes and OEMs. It exists precisely because AS9100 certifies a quality management system but does not audit the technical adequacy of a heat treat furnace survey, a plating bath, or an NDT technician's qualification. The two work together: AS9100 governs the shop, NADCAP governs the process.
For Fort Lauderdale buyers, this gap is the single most common source of quality risk in aerospace sourcing. A capable local machine shop with valid AS9100 will subcontract heat treat or coating to an outside processor, and that processor must hold the relevant NADCAP accreditation for the work to be acceptable to a prime. Verifying the machine shop's AS9100 and stopping there leaves the riskiest operations unverified.
Reading eAuditNet and Matching the Right Process Scope
NADCAP accreditations are tracked in eAuditNet, the database maintained by the Performance Review Institute. This is where a Fort Lauderdale buyer verifies a special-process supplier, and it's more granular than most other certification databases. NADCAP accredits by specific process commodity, Heat Treating (HT), Chemical Processing (CP), Coatings (CT), Welding (WLD), Nonconventional Machining and Surface Enhancement, Nondestructive Testing (NDT), and others, and within each commodity by specific processes and even specific specifications.
That granularity is the whole point. A processor accredited for nondestructive testing penetrant inspection is not necessarily accredited for radiographic inspection. A heat treater accredited for aluminum solution treatment may not hold accreditation for the specific alloy or process your part requires. When you pull a supplier in eAuditNet, match the accreditation scope to the exact process and specification on your drawing, not just the general commodity.
Also confirm the accreditation is current and check for merit status, NADCAP awards extended accreditation intervals to processors with strong audit histories, which is a useful quality signal. Because Fort Lauderdale's local pool of NADCAP-accredited special processors is narrower than its general machining base, buyers frequently find the machine shop locally but route certain special processes to accredited providers elsewhere in Florida or the Southeast. That's normal; what matters is that the accreditation chain holds for every special process on the part.
Building the Flowdown So the Chain Doesn't Break
The discipline that protects a Fort Lauderdale aerospace buyer is proper flowdown. The prime's requirements, AS9100, ITAR where applicable, NADCAP for special processes, and the specific process specifications, must flow down through your machine shop to every subcontracted special processor. A break anywhere in that chain can render the whole part nonconforming even if each shop did good work, because the documentation and accreditation linkage failed.
In practice, this means your purchase order to the machine shop should explicitly require that special processes be performed by NADCAP-accredited sources to the called-out specifications, and that the certifications flow back with the parts. Ask the machine shop for its approved supplier list and confirm the special processors on it hold current eAuditNet accreditation for the relevant commodity and specification. A mature Fort Lauderdale aerospace shop manages this flowdown as routine and can show you the chain at quote time.
The documentation that comes back should let you trace every special process: heat treat charts or furnace records, plating certifications with thickness data, NDT reports with technician qualifications, and certificates of conformance tying each operation to the accredited source and specification. If any of those are missing or vague, the chain has a gap. The buyers who avoid program-delaying surprises are the ones who verify the full special-process chain before release rather than discovering a missing NADCAP scope during source inspection or first article.
Frequently Asked Questions
NADCAP accredits special processes, operations whose results cannot be fully verified by inspecting the finished part, against industry-consensus technical requirements, while AS9100 certifies a supplier's overall quality management system without auditing the technical adequacy of those specific processes. Special processes include heat treating, chemical processing, coatings and plating, welding and brazing, nondestructive testing, and chemical milling. You cannot measure your way to confidence that a heat treat achieved the correct metallurgical structure or that an anodize coating has uniform thickness and adhesion, so these operations carry latent failure risk that surfaces only in service. NADCAP, administered by the Performance Review Institute, audits the furnace surveys, plating baths, welder and NDT technician qualifications, and process controls behind these operations against checklists developed with aerospace primes and OEMs. The two credentials work together: AS9100 governs the shop, NADCAP governs the process. For a Fort Lauderdale buyer, verifying a machine shop's AS9100 while ignoring whether its outside heat treater or plater holds NADCAP leaves the riskiest operations on the part entirely unverified.
Use eAuditNet, the database maintained by the Performance Review Institute, which tracks all NADCAP accreditations. It is more granular than most certification databases: NADCAP accredits by specific process commodity, Heat Treating, Chemical Processing, Coatings, Welding, Nondestructive Testing, and others, and within each commodity by specific processes and even specific specifications. That granularity is essential to use correctly. A processor accredited for penetrant nondestructive testing is not automatically accredited for radiographic inspection, and a heat treater accredited for one aluminum process may not hold accreditation for the specific alloy or specification your part requires. When you look up a Fort Lauderdale-area supplier in eAuditNet, match the accreditation scope to the exact process and specification called out on your drawing rather than the general commodity. Confirm the accreditation is current, and check for merit status, NADCAP grants extended accreditation intervals to processors with strong audit histories, which is a useful quality indicator. Because the local accredited pool is narrower than the general machining base, some special processes will route to accredited providers elsewhere in Florida or the Southeast.
Because the special processes that NADCAP covers are exactly the operations where defects are hardest to detect and most likely to cause in-service failures, and they are almost always subcontracted rather than performed in-house. A capable Fort Lauderdale machine shop with valid AS9100 will send heat treat, coating, or NDT to outside processors, and those processors must hold the relevant NADCAP accreditation for the work to be acceptable to a prime. The most common failure pattern is a buyer who verifies the machine shop's AS9100 through OASIS, feels covered, and never confirms the special processors' accreditations. If the heat treater lacks NADCAP scope for the specific process, or the plating certs don't trace to an accredited source, the entire part can be deemed nonconforming even though the machining was perfect. The risk concentrates in the chain because each handoff is a place where documentation, accreditation scope, or specification flowdown can break. Verifying the full special-process chain before release, not at source inspection, is what separates buyers who avoid program delays from those who discover the gap too late.
Proper flowdown is the discipline that keeps the special-process chain intact. The prime's requirements, AS9100, ITAR where applicable, NADCAP accreditation for each special process, and the specific process specifications, must flow through your machine shop to every subcontracted special processor, because a break anywhere can render the part nonconforming even if each shop did good work. Practically, your purchase order to the machine shop should explicitly require that special processes be performed by NADCAP-accredited sources to the called-out specifications and that the certifications flow back with the parts. Ask the shop for its approved supplier list and confirm the listed special processors hold current eAuditNet accreditation for the relevant commodity and specification. A mature Fort Lauderdale aerospace shop manages this flowdown routinely and can show the chain at quote time. The returned documentation should let you trace each special process: heat treat charts or furnace records, plating certifications with thickness data, NDT reports with technician qualifications, and certificates of conformance tying each operation to the accredited source and specification. Missing or vague records signal a gap in the chain.
