NADCAP Accredited Special Process Suppliers in Atlanta, GA

NADCAP, the National Aerospace and Defense Contractors Accreditation Program, is administered by the Performance Review Institute and accredits specific special processes against industry-developed audit criteria. It is process-specific, not a blanket company certification. A shop is accredited for, say, heat treating to AMS2750 pyrometry requirements, or for fluorescent penetrant inspection, or for a particular chemical processing line, and each accreditation stands on its own. This specificity is the whole point and the most common source of confusion. A processor in metro Atlanta may proudly hold NADCAP accreditation, but if your part needs a process or commodity outside its accredited scope, that accreditation does not cover your work. The commodities span heat treatment, chemical processing, coatings, nondestructive testing, welding, materials testing, and more, and each is audited separately against the relevant Aerospace Material Specifications and prime requirements. For buyers serving Atlanta's aerospace base, NADCAP is non-negotiable for special processes on flight hardware because the primes mandate it. Lockheed Martin and other defense customers will not accept a special process from a non-accredited source on controlled parts, which is why the local processing base has invested in accreditation across the common aerospace commodities.

NADCAP accreditations are tracked in eAuditNet, the PRI's online system, which is the authoritative place to verify an Atlanta supplier. eAuditNet lets you confirm a supplier holds a current accreditation, the specific commodity and scope, and the accreditation status. Because the program is rigorous, accreditations can be suspended or have findings, so a current, clean status is meaningful. The critical step is matching the accredited scope to your exact requirement. If your part calls out heat treatment to a specific AMS spec, verify the supplier is accredited for that commodity and that its pyrometry conforms to AMS2750, the standard governing furnace temperature uniformity and instrument calibration. For NDT, confirm the specific method, whether penetrant, magnetic particle, ultrasonic, or radiographic, since each is separately accredited and requires certified technicians at the appropriate levels. Red flags include a supplier who references NADCAP generally but cannot point to the specific commodity scope your part needs, an accreditation that is suspended or lapsed in eAuditNet, or a processor whose scope covers a different alloy family or process variant than your specification. In aerospace, close is not good enough; the accredited scope must match the callout on your drawing exactly.

In practice, most NADCAP special processing in Atlanta is not performed by the machine shop building your part but by dedicated processors the shop routes work to. A Marietta-area precision machine shop holding AS9100 will outsource heat treat to an accredited heat-treater, plating to an accredited chemical processor, and NDT to an accredited inspection house, then manage the flowdown so each step is documented and traceable. This creates a chain of responsibility a buyer needs to understand. Your purchase order requirements flow from you to the machine shop, and from the machine shop to its sub-tier processors. The accountability for ensuring each special process is performed by a NADCAP-accredited source on the customer's approved-source list rests with your supplier, but you should verify how it manages that flowdown rather than assuming it is handled. The documentation must follow the part through every step. Expect process certifications that trace heat-treat lots with the associated pyrometry records, NDT reports identifying the method and technician certification level, and plating records showing thickness and process parameters, all referencing your part and purchase order. A break in that documentation chain is a quality escape, regardless of whether each processor was individually accredited.
