## Key Takeaways For AS9100D Supplier Verification

- AS9100D certification applies to an organization’s quality management system and must match the processes and materials on each PO.
- Scope statements can change or be suspended, so buyers should confirm the current scope in the IAQG OASIS database before releasing a purchase order.
- A complete pre-PO document package includes the AS9100D certificate, quality manual excerpt, AS9102 FAI reports, material certifications with heat-lot traceability and certificates of conformance.
- Aerospace controls such as configuration management, counterfeit part prevention, first article inspection and full traceability must appear as documented, active processes.
- Precision Advanced Manufacturing holds AS9100D and ISO 9001:2015 registrations, maintains ITAR registration and performs multi-axis CNC and Swiss-type machining of titanium and Inconel in-house across its Anaheim, California and Texas locations.

## AS9100D Certification And Organizational Responsibility

AS9100D is the aerospace quality management system standard published by SAE International in 2016, built on ISO 9001:2015 and adding aviation, space and defense requirements such as configuration management, counterfeit part prevention, first article inspection, risk management and traceability. Certification applies to an organization’s quality management system and defines how that organization controls processes that affect product quality.

Certification bodies issue AS9100D certificates to organizations, while individuals receive training or auditor credentials that support the system. Buyers benefit when suppliers distinguish clearly between organizational registration and personal training claims in sales material and proposals.

For related guidance on finding certified suppliers, see [How To Find AS9100 Certified Aerospace Manufacturers](https://precisionam.com/articles/as9100-certified-aerospace-manufacturers-us/?utm_term=as9100d-certified-aerospace-machining&utm_campaign=ai_growth_agent).

### AS9100 vs AS9100D: What The Revision Difference Means

AS9100D is the 2016 revision aligned to ISO 9001:2015. [AS9100 Rev C was superseded when the IAQG aligned the 2016 revision transition with the ISO 9001:2015 transition period ending September 2018](https://nimblemfg.co/2026/06/18/as9100-rev-d-complete-guide), so a supplier that still cites Rev C operates out of compliance with the current standard. AS9100D replaced Rev C and [remains the current certifiable revision](https://resources.utec.co/mh-aerospace-gse/as9100d-to-ia9100-aerospace-tooling-suppliers).

[The successor standard, IA9100, remains a work in progress with a publication target tied to ISO 9001:2026](https://qmslearning.com/blog/ia-9100-rev-e-changes), so AS9100D is the revision buyers should expect to see on today’s certificates. Verification steps should always include a check of the exact revision printed on the certificate, not just a generic reference to AS9100.

## How To Read A Certificate’s Scope Statement

The scope statement on an AS9100D certificate defines what the shop is certified to do. Matching that scope line to the purchase order is the first substantive qualification check for any aerospace machining program.

A scope that covers “machined components for aerospace and defense applications” covers machining work. A scope limited to fabrication, distribution or maintenance does not cover machined titanium or Inconel parts, even when those processes occur at the same address. Scope language that supports machining requirements often includes phrases such as “CNC machining of precision components for aviation, space and defense.”

Language limited to “sheet metal fabrication” or “distribution of aerospace hardware” applies to different activities and does not extend to machined part production. Buyers gain clarity when they compare the scope wording directly against the PO’s processes, materials and end use.

[A multi-site company can hold separate certificates per location, and a certificate issued for one plant does not cover another](https://domesticsuppliers.com/blog/how-to-verify-as9100-in-oasis). Buyers should confirm which specific site a certificate covers before assuming company-wide qualification, then carry that site information into the OASIS registry check that follows.

## How To Verify An AS9100D Certificate In The IAQG OASIS Database

The [IAQG OASIS database](https://oasis.iaqg.org) is the authoritative registry where accredited certification bodies publish AS9100D certificates. [A certificate becomes valid only when it appears in OASIS](https://spilma.com/en/guides/qms-iso-9001-as-9100-iso-13485-tl-9000), because submission forms part of the certification body’s IAQG accreditation requirements. Supplier PDFs show a point in time, while OASIS reflects the certification body’s current record.

1. Search OASIS by the supplier’s full legal name, since certification records are filed under the legal entity.
2. Open the record and confirm the certificate number matches the PDF provided by the supplier.
3. Read the scope statement against the purchase order’s processes and materials.
4. Check the certification status and the most recent audit date.
5. Confirm the surveillance audit falls within the three-year certification cycle and that the certificate remains active.

[OASIS includes a Change Summary view listing companies whose certificates were recently suspended, withdrawn or deleted](https://domesticsuppliers.com/blog/how-to-verify-as9100-in-oasis), which provides a level of transparency that a static PDF cannot match. A suspended or withdrawn status means the shop’s quality management system no longer met the standard’s requirements at the time of the triggering audit. When a supplier record does not appear in OASIS, buyers can request the certificate number and certification body name, then confirm status directly with that body.

## Pre-PO Document Package For AS9100D Machine Shops

A structured pre-PO document package confirms that the shop’s system, processes and records align with aerospace requirements before production begins. Each document in the package supports a specific qualification decision for the work on the purchase order.

- **AS9100D certificate and scope statement** show that the organization holds current certification for the processes and materials on the PO.
- **Quality manual excerpt** explains how the shop controls configuration, risk and nonconformances within its documented quality management system.
- **[AS9102 First Article Inspection reports](https://saemobilus.sae.org/topics/quality-reliability-and-durability/quality-management-systems/quality-audits)** demonstrate that the production process was verified against every drawing characteristic, with material and process accountability documented across all three forms.
- **Material certifications with heat-lot traceability** connect the raw stock to the mill certificate and the finished part, which satisfies AS9100D traceability requirements at the material level.
- **Certificate of conformance** provides the shop’s formal attestation that delivered parts conform to the drawing, specification and purchase order requirements.
- **Inspection reports** supply dimensional evidence with measurement equipment identified and calibration status confirmed.

## Aerospace Controls That Go Beyond ISO 9001

Configuration management, counterfeit part prevention, first article inspection and traceability define the controls that separate aerospace machining environments from ISO 9001-only shops. Buyers gain stronger assurance when they treat each of these controls as a qualification checkpoint.

![Machined metal flanges arranged after finishing and deburring.](https://cdn.aigrowthmarketer.co/1785164177118-60d8e0c39169.webp)**Finishing and deburring are where tolerance becomes function — clean edges, controlled surface finish, and coatings applied and documented to specification.**

- **Configuration management** follows [AS9100D Clause 8.1.2, which requires documented control of drawing revisions, specification changes and material substitutions across the product lifecycle](https://qmslearning.com/blog/as9100-requirements). A compliant shop maintains change control records that allow the as-built configuration to be compared against the as-designed baseline.
- **Counterfeit part prevention** follows [AS9100D Clause 8.1.4, which requires documented processes for approved-source purchasing, incoming verification and quarantine and reporting of suspect parts](https://thestandardsnavigator.com/tag/as5553). For machining and fabrication suppliers, [AS6174 provides the relevant reference for raw material and hardware](https://thestandardsnavigator.com/tag/supplier-flow-down-requirements), while [AS5553 applies when electronic or electromechanical parts are procured or integrated](https://thestandardsnavigator.com/tag/as5553).
- **First article inspection** follows [AS9102 Revision C, which defines three forms covering part number accountability, material and process accountability and characteristic accountability](https://legalclarity.org/as9102-forms-1-2-3-first-article-inspection). A compliant FAI includes material traceability and measured results for every design characteristic on the drawing.
- **Traceability** relies on heat-lot and serial records that reconstruct the part’s history from raw material to shipment, with mill certifications tied to specific shipments and verified at receiving inspection.

### AS9100D vs ISO 9001 For Aerospace Machining

[AS9100D incorporates ISO 9001:2015 in full and adds the aerospace controls above, so an ISO 9001-only shop has no obligation to meet FAI, configuration management or counterfeit part requirements](https://nimblemfg.co/2026/06/18/as9100-rev-d-complete-guide). An ISO 9001 certificate does not satisfy aerospace customer flow-down requirements for flight-critical or defense parts. The gap between the two standards reflects missing documented processes that aerospace primes audit and enforce during supplier oversight.

## What To Look For In A U.S. AS9100D Machining Partner

Effective partner selection mirrors the criteria a quality engineer applies during an audit. The first checks focus on current AS9100D registration with a scope that matches the purchase order and on ITAR registration for defense and space programs.

Once those foundations are in place, buyers can review in-house capabilities such as multi-axis CNC and Swiss-type machining of aerospace-grade materials, integrated fabrication and finishing and the strength of traceability and inspection documentation. Scalability from prototype through full-rate production rounds out the technical and operational review.

Multi-axis CNC machining holds tight tolerances part after part, with full material traceability behind every feature.**

Precision Advanced Manufacturing holds AS9100D and ISO 9001:2015 registrations and maintains ITAR registration. The company performs multi-axis CNC and Swiss-type machining of titanium and Inconel in-house, with integrated precision fabrication, specialty welding, finishing and kitting. Full traceability and inspection documentation support every production step, and operations support prototype development through multi-shift, full-rate production across Anaheim, California and Texas locations.

General production machining shops often coordinate special processes such as anodizing, passivation, plating, heat treatment and finishing through outside suppliers. The buyer must then qualify each processor separately and confirm that flow-down requirements reach every tier. Keeping aerospace-specific capabilities and documentation inside one certified system shortens the traceability chain and lowers the qualification burden.

## Conclusion: Verify First, Then Release The PO

Precision Advanced Manufacturing meets the partner criteria described above, with AS9100D and ISO 9001:2015 registrations, ITAR registration and in-house machining of titanium and Inconel supported by scalable production across Anaheim, California and Texas.

The verification sequence starts with confirming the standard definition and revision, then moves to reading the scope statement against the purchase order and reviewing the OASIS record field by field. Buyers then assemble the pre-PO document package, confirm that aerospace-specific controls operate as documented and apply the partner criteria before committing to any supplier. A certificate on file begins the process, while these verification steps turn “certified” into “ready to receive a purchase order.”
