## Key Takeaways for Aerospace Sheet Metal Qualification

- AS9100D certification alone does not qualify a supplier. Buyers must verify that certificate scope covers fabrication, finishing and assembly.
- ITAR registration and Nadcap accreditation are separate requirements. Suppliers must state exact status before drawings are released.
- Fragmented supply chains create traceability gaps and delays. Vertically integrated providers reduce handoffs and support aerospace programs more consistently.
- AS9102 first article inspection, material lot traceability and documented quality management support customer audits and FAI reviews.
- Fabcon provides AS9100D-certified, vertically integrated fabrication and assembly from prototype through mid-volume production.

## The Problem: Certification Logos Do Not Equal Qualification

AS9100D is a quality management system certification, not a process approval. A certificate proves nothing about the specific operations being outsourced unless its scope statement names them: fabrication, finishing and assembly. Buyers who qualify on logos rather than scope language typically discover the gap at first article, not at RFQ.

ITAR registration is a separate requirement. There is no government-issued ITAR certification. Manufacturers of defense articles register with the U.S. Department of State Directorate of Defense Trade Controls under 22 CFR Part 122 and [registration confers no export rights](https://ecfr.gov/current/title-22/chapter-I/subchapter-M/part-122). A supplier displaying an ITAR logo has registered only its status with DDTC.

[Nadcap accredits a specific process at a specific site, not a company](https://irecruit.co/insights/nadcap-explained-accreditation-aerospace-special-processes). [A supplier holding AS9100D and no Nadcap accreditation cannot satisfy a purchase-order quality clause that requires Nadcap welding or heat treatment](https://aviationsouk.com/knowledge/aerospace-accreditation-nadcap-as9100-iso-9001).

Fragmented supply chains create a second failure mode. When fabrication, finishing and assembly sit at separate vendors, each handoff introduces scheduling delays, documentation gaps and quality discrepancies that the buyer absorbs. A defensible shortlist rests on four checks: verified scope, a documented first article process, lot-level traceability and a stated ITAR position confirmed before the drawing is released.

## The Solution: Core Requirements for Aerospace Sheet Metal Services

Aerospace sheet metal fabrication services provide precision-formed metal components and assemblies under a documented quality management system. A qualified provider holds AS9100D certification with a scope statement that covers the specific operations being sourced. It conducts first article inspection per AS9102, maintains material certifications and lot traceability to the raw-material heat and states its ITAR registration status before a controlled drawing is released.

In-house laser cutting delivers tight-tolerance blanks with the speed and repeatability that high-mix, infrastructure-grade programs demand.**

Fabcon holds AS9100D and ISO 9001:2015 certifications that support documented quality management and traceability throughout its manufacturing processes. Fabcon is not ITAR-registered. Buyers whose programs require ITAR registration should confirm that requirement before releasing a drawing.

## How to Verify AS9100D Scope and ITAR Registration

[AS9100 certification data is reported by the certification body to the IAQG OASIS database](https://iso9001expert.com/blog/iso-9001-as9100-rev-d-aerospace-adds-quality-management), which aerospace primes use to verify supplier certification status, scope and audit history. [ISO 9001 certificates are generally not tracked in a shared public system](https://iso9001expert.com/blog/iso-9001-as9100-rev-d-aerospace-adds-quality-management). Buyers should read the certificate scope statement and expiry date, confirm the certification body record in OASIS and request a recent redacted AS9102 Form 3 sample to verify that the first article process operates as stated.

ITAR registration requires a separate check. [Under 22 CFR 122.1(a) any person engaged in the United States in the business of manufacturing defense articles must register with DDTC](https://ecfr.gov/current/title-22/chapter-I/subchapter-M/part-122) and [registration must be renewed annually](https://ecfr.gov/current/title-22/chapter-I/subchapter-M/part-122). Registration does not confer export rights or privileges. Buyers should confirm whether ITAR registration applies to a part or program before releasing a drawing to any supplier.

Fabcon is not ITAR-registered. Fabcon AS9100D and ISO 9001:2015 certifications, described above, support documented quality management and traceability. For a detailed review of Fabcon certification posture, see [AS9100 Certified Sheet Metal Fabrication for Aerospace](https://fabcon.com/articles/sheet-metal-fabrication/as9100-certified-sheet-metal-fabrication/?utm_source=ai-growth-agent&utm_term=aerospace-sheet-metal-fabrication-services).

## Prototype vs. Production Runs in Aerospace Sheet Metal

Scope and registration checks establish whether a supplier is eligible. The next question concerns how its process changes between prototype and production. In prototyping, tooling is provisional and the first article establishes the baseline. [AS9102 defines five events that trigger a first article inspection](https://omssoftware.com.au/blog/aerospace-inspection-nadcap-software): [first production of a new part number, a design change affecting form, fit or function, a process or tooling change, a production lapse of typically 24 months and a change of manufacturing source or facility](https://omssoftware.com.au/blog/aerospace-inspection-nadcap-software). Inspection intensity rises with part criticality, and the documentation burden rises with it.

Special processes such as heat treatment, welding and chemical processing are accredited under [Nadcap](https://thestandardsnavigator.com/2026/08/05/nadcap-vs-as9100), while AS9100D governs the quality management system and requires control of those processes. A supplier without Nadcap accreditation for a required special process must either route that work to a Nadcap-accredited sub-tier supplier or disclose the gap before the purchase order is placed.

Fabcon supports prototype through mid-volume production under AS9100D. Fabcon does not hold Nadcap. Programs requiring Nadcap-accredited heat treatment, welding or chemical processing should confirm that requirement before award.

## Materials and Processes to Confirm Before Quoting

Material and process fit determine whether a supplier can support a program without excessive outsourcing. Buyers should confirm the material families a fabricator works with, including aluminum grades such as 2024, 5052 and 6061, stainless steel, titanium and nickel alloys. They should also confirm which processes run in-house versus those routed to sub-tier suppliers. Each outsourced special process adds a handoff, a purchase order and a traceability boundary to manage.

Fabcon in-house capabilities include laser cutting, CNC punching, forming, welding and finishing, plus CNC machining, powder coat, wet paint, screen printing and light electromechanical assembly that includes wiring and component integration. Fabcon does not perform robotic welding and does not offer CARC coating. Material availability and process suitability should be confirmed at quoting for each specific program.

![Powder-coating and material-handling racks on the Fabcon shop floor.](https://cdn.aigrowthmarketer.co/1785163025306-7525a9a10f59.webp)**In-house finishing — powder coat, wet paint, and silkscreen — keeps cosmetic standards consistent and removes a supplier handoff from the build.**

[Agile Metal Fabrication for Mid-Volume High-Mix Programs](https://fabcon.com/articles/contract-manufacturing-agile-production/agile-metal-fabrication-services/?utm_source=ai-growth-agent&utm_term=aerospace-sheet-metal-fabrication-services) covers how Fabcon production cells adapt to evolving bills of materials and mixed-SKU programs.

## Why Integrated Fabrication, Finishing and Assembly Reduce Risk

Integrated fabrication, finishing and assembly reduce risk by limiting vendor handoffs. Each additional vendor in a fabrication program adds a purchase order, a schedule to reconcile and a boundary where traceability can break. A prime contractor can run an exemplary quality system on its own factory floor and still ship a nonconforming assembly if the failure originated upstream in a supplier the prime has never audited directly.

Aerospace total cost of ownership extends well beyond the per-operation quote. It includes transport between suppliers, purchase order volume, supplier management, inspection fees, delays, expedited shipping, scrap and rework and documentation burden. Vendor handoff delays and quality finger-pointing function as qualification criteria, not minor inconveniences.

Fabcon performs fabrication, finishing, CNC machining and light electromechanical assembly under one roof in its 118000-square-foot Santa Ana facility. Regional aerospace sheet metal job shops typically stop at metal and leave coating, wiring and assembly to separate vendors. Large global contract manufacturers offer integration but impose high minimums and long onboarding timelines. Fabcon sits between the two: vertically integrated capability without the rigidity or volume thresholds of a large contract manufacturer.

## Aerospace Sheet Metal Supplier Qualification Checklist

The following checklist supports internal review by a quality engineer or program manager and incorporates capability fit.

1. Verify that the AS9100D certificate scope statement covers the specific operations being sourced and confirm that the certificate is current in the [IAQG OASIS database](https://iaqg.org/oasis).
2. Confirm the supplier AS9102 first article inspection process, including Forms 1, 2 and 3, and request a redacted sample FAIR package.
3. Confirm material certifications and lot traceability. Each material certificate should reference the specific heat or lot incorporated into the inspected article, per [AS9102C Form 2 requirements](https://sae.org/standards/content/as9102).
4. Confirm ITAR registration status against program requirements before releasing a controlled drawing for quotation.
5. Confirm in-house finishing and assembly scope, including powder coat, wet paint, screen printing and electromechanical assembly, and identify any operations routed to sub-tier suppliers.
6. Confirm the prototype-to-production transition plan, including the events that trigger a delta or full FAI.
7. Confirm capacity fit for mid-volume programs and the supplier approach to high-mix, evolving bills of materials.
8. Confirm facility location, single-site versus multi-site scope and audit readiness for a second-party supplier audit.
