AS9100 Rev D Aerospace Suppliers Near St. Cloud, MN

AS9100 certificates are tracked in OASIS, the Online Aerospace Supplier Information System maintained by the IAQG. This is the single most useful verification step a buyer can take. Ask the supplier for their OASIS-listed certificate and confirm the status reads active, the certification body is accredited, and the scope covers the processes you are buying. OASIS also shows certificate suspensions, which a lobby plaque never will. The harder verification is special-process flowdown. AS9100 requires the supplier to control special processes, but most machine shops do not perform heat treating, anodizing, chemical processing, or nondestructive testing in-house. They send those to subtier processors. What you must confirm is that the supplier flows your aerospace requirements down to those subtiers and that the subtiers hold NADCAP accreditation for each process. A shop with a clean AS9100 certificate that sends parts to an uncontrolled plating vendor has a gap that will surface at your first prime audit. Ask specifically: who heat treats, who plates or anodizes, who performs penetrant or radiographic inspection, and is each one NADCAP accredited for that process. Then ask to see the flowdown language in the purchase orders the shop issues to those vendors. A supplier that has genuinely operated in aerospace will produce this without friction.

AS9100 Rev D added explicit requirements that distinguish aerospace work from commercial machining, and two matter most to a buyer. The first is configuration management. Your part will revise; the question is whether the shop runs to the exact drawing revision and effectivity you specified or to whatever print they happened to have on file. A real AS9100 system locks revision control so that a part is manufactured and inspected against the released configuration, and frozen planning prevents an operator from quietly improving a process mid-run. The second is counterfeit-part prevention. For machined hardware this centers on raw material provenance. Aerospace alloys such as titanium 6Al-4V, Inconel 718, and aerospace-grade aluminum like 7075-T651 must trace to a legitimate mill with full certification, not to gray-market stock of unknown origin. AS9100 Rev D requires a counterfeit-prevention process, and you should expect mill certs traceable to the heat or lot, with the supplier verifying authenticity rather than assuming it. These controls are why AS9100 work costs more than commercial machining of the same geometry. The metal-cutting may be identical; the documentation, material control, and frozen planning are not. A buyer who understands what they are paying for stops treating an AS9100 quote as overpriced and starts treating it as correctly priced for flyable hardware.

The first-article inspection in aerospace is non-negotiable and follows AS9102. Every characteristic on the drawing is balloned, measured, and recorded on Forms 1, 2, and 3, tying each dimension to the inspection result and the measurement method. For your first build of a part, and on any change that affects form, fit, or function, you should receive a complete AS9102 FAIR before production parts ship. This is the document your own quality system and your prime customer will demand to see. With production lots, require a certificate of conformance, material certifications traceable to the mill, and certs for every special process performed, each tied to the NADCAP-accredited processor that did the work. Where the print calls out nondestructive testing, you need the NDT reports and the inspector's certification level. Where it calls out a coating thickness or hardness, you need the actual measured values, not a statement that the part conforms. Keep these records as a package per lot. Aerospace traceability is retrospective; years after delivery, a prime may need to trace a fielded part back to its heat number, its heat-treat run, and its inspection record. A St. Cloud supplier running a mature AS9100 system already assembles this documentation by default. Your job as a buyer is to require delivery of the full package and to reject any lot that ships without it.
