NADCAP Special Process Accreditation for Honolulu, HI Manufacturers

NADCAP accreditation certifies the special processes, heat treatment, non-destructive testing, welding, chemical processing, and coatings, that aerospace primes require for flight-critical hardware. On Oahu, where the industrial base is thin, the realistic picture is that local shops handle machining and fabrication while NADCAP-accredited special processes are sourced and routed deliberately, sometimes off-island, so buyers need to understand the qualification and the logistics together.

NADCAPAS9100ISO 9001
NADCAP, the National Aerospace and Defense Contractors Accreditation Program managed by the Performance Review Institute, accredits individual special processes rather than companies as a whole. A facility holds NADCAP accreditation for specific commodities such as heat treating, non-destructive testing, welding, chemical processing, coatings, or non-conventional machining, each audited against detailed industry-consensus checklists. This is fundamentally different from AS9100, which certifies a shop's overall quality system. The process-specific nature is the key thing for an Oahu buyer to internalize. A part that requires precipitation heat treat and fluorescent penetrant inspection needs each of those processes performed by a NADCAP-accredited source for the relevant commodity, and a shop accredited for welding is not thereby accredited for heat treat. When your drawing or specification calls out a special process to NADCAP requirements, that callout points at a specific accreditation that must exist somewhere in the supply chain. Because Honolulu's industrial base is small, the full slate of NADCAP-accredited special processes is generally not available on a single Oahu floor. That does not block local sourcing; it means the special-process steps get routed to accredited processors, frequently on the mainland, under controlled conditions. Understanding which processes your part needs and where they can be accredited is the foundation of a workable Oahu aerospace sourcing plan.

Routing Special Processes When the Island Cannot Do It All

The practical workflow for NADCAP-dependent work on Oahu is a hybrid one. A local AS9100 machining or fabrication shop performs the work it is qualified for, then special processes that require NADCAP accreditation, heat treat, anodize or other coatings, welding qualification, NDT, are sent to accredited processors. Some of those processors are on the mainland, which adds ocean or air freight transit to the routing, so lead time planning has to account for the round trip. Under AS9100 clause 8.4, the prime supplier you contract with remains responsible for controlling these outsourced special processes, including verifying the processor's current NADCAP accreditation for the specific commodity and ensuring the work meets the specification. As a buyer, ask the Honolulu shop to map the full routing for your part: which operations stay on the island, which go off-island, which NADCAP-accredited houses perform them, and how many freight days each leg adds. This transparency separates a serious aerospace supplier from a marginal one. A capable shop manages the special-process supply chain as a normal part of the job and can show you the accreditation status of every processor it uses. A vague answer about where heat treat or NDT happens is a warning sign for flight-critical hardware, where an unaccredited or expired source can void the part's airworthiness.

Verifying Accreditation and the Records You Must Receive

NADCAP accreditation is verifiable through the Performance Review Institute's eAuditNet system, which lists accredited suppliers by commodity and shows current status. For every special-process source in your part's routing, confirm the accreditation covers the exact commodity required and is current, not lapsed. Build this check into supplier qualification, and have the prime Honolulu supplier document the accreditation status of each sub-tier processor it uses. The records that travel with a NADCAP-processed part are non-negotiable. Expect process certifications from each accredited processor documenting that heat treat, coating, welding, or NDT was performed to the specification, along with the supporting data the spec requires, such as hardness results, coating thickness, or inspection reports. These join the material test reports, certificate of conformance, and AS9102 first article inspection report in the part's data package. Keep this documentation, because it is the proof of airworthiness and the only way to reconstruct what happened to a part that is later questioned in service. In Hawaii, where re-sourcing means an ocean transit, a complete and accurate special-process record set is the difference between a quick disposition and a stranded program. Insist that the full package be delivered as a contractual deliverable with the parts.

Frequently Asked Questions

The full range of NADCAP-accredited special processes is generally not available on a single Oahu floor, because Honolulu's industrial base is small and special-process accreditation is expensive to obtain and maintain for processes like heat treat, NDT, welding, chemical processing, and coatings. The realistic picture for an Oahu aerospace buyer is a hybrid one: a local AS9100 machining or fabrication shop performs the work it is qualified for, and NADCAP-dependent special processes are routed to accredited processors, frequently on the mainland, under controlled conditions. This does not prevent local sourcing; it means the special-process steps are managed as part of the routing rather than done in-house. Some individual processes may be available locally depending on demand at any given time, so it is worth asking specific shops what they hold. The key is to verify accreditation through the Performance Review Institute's eAuditNet system for the exact commodity your part requires and to have the prime supplier document the accreditation status of every processor in the chain. Use ManufacturingBase to identify Oahu shops that manage NADCAP routing.
They operate at different levels and aerospace work usually requires both. AS9100 Rev D certifies a shop's overall quality management system, how it controls processes, traceability, configuration, and first article inspection across everything it does. NADCAP accredits individual special processes, such as heat treating, non-destructive testing, welding, chemical processing, or coatings, each audited against detailed industry-consensus checklists for that specific commodity. A shop can be AS9100 certified without holding any NADCAP accreditation, and a NADCAP-accredited processor is accredited only for the specific commodities it was audited for, not for everything. For a flight-critical part, you typically need AS9100 governing the build and traceability and NADCAP accreditation covering any special process the drawing calls out. On Oahu the common arrangement is a local AS9100 machining shop that routes special processes to NADCAP-accredited houses, often off-island, while remaining responsible under AS9100 clause 8.4 for controlling that outsourced work. Map your drawing's requirements carefully, because a callout to a NADCAP special process must be satisfied by an accredited source somewhere in the chain regardless of the shop's AS9100 status.
They can dominate the schedule, so they deserve early attention. When a part requires a NADCAP special process that is not available locally, the operation gets sent to an accredited processor, frequently on the mainland, which adds ocean or air freight transit each way on top of the processing time itself. Ocean transit runs roughly four to six days per direction, so a single off-island heat treat or coating step can add a week or more to the routing, and a part needing multiple special processes routed separately can compound that significantly. The way to manage this is to have the Honolulu shop map the complete routing for your part up front, identifying which operations stay on the island, which go off-island, which accredited houses perform them, and the freight days each leg adds. With that map you can plan realistic delivery dates, decide whether to air freight to compress critical steps, and identify opportunities to batch off-island operations. For urgent sustainment work, this planning is what determines whether local sourcing actually beats sending the whole part to a mainland aerospace shop, so do it before you commit.
Each accredited processor must provide a process certification documenting that the special process, heat treat, coating, welding, NDT, or chemical processing, was performed to the applicable specification, along with the supporting data that specification requires. For heat treat that often means hardness or mechanical property results; for coatings, thickness and adhesion data; for NDT, the inspection report and technique sheet; for welding, the qualified procedure and operator records. These process certifications join the rest of the data package: material test reports traceable by heat or lot, the certificate of conformance, and the AS9102 first article inspection report. Together they constitute the proof of airworthiness for the part. You should also be able to tie each process certification back to a NADCAP-accredited source whose accreditation for that exact commodity was current at the time of processing, verifiable through eAuditNet. Insist that this full package be delivered with the parts as a contractual deliverable. In Hawaii this matters even more, because if a part is later questioned in service, re-sourcing means an ocean transit, and complete records are the only way to disposition the issue quickly rather than scrapping and starting over.
