Five guides covering everything a CNC machining shop needs to know about AS9100D: certification requirements, building a compliant QMS, understanding every key clause, navigating Rev D changes and audit preparation, and managing nonconformances through effective corrective action.
This series is written for machine shop owners and quality managers pursuing AS9100 registration for the first time, or preparing for surveillance audits. Each guide stands alone, but together they cover the full arc from "what is AS9100D and do we need it" through running a live NCR and closing a corrective action request with verified effectiveness evidence. Guides 3–5 are live now; Guides 1–2 are in progress. See how we apply this for aerospace & defense manufacturers.

What AS9100D covers, who needs it, and the certification pathway — scoping, accreditation bodies, and what aerospace buyers actually check when they ask for AS9100 certification.
Coming soonKey clauses 4–10 translated into shop-floor language: risk-based thinking, organizational context, planning, support, operations, performance evaluation, and improvement — what each one actually requires of a machining shop.
Coming soonQuality policy, document control, process maps, and internal audit protocols for a CNC machining QMS. Covers what AS9100D requires you to document, how to structure your QMS, and how aerospace buyers evaluate supplier quality systems.
Read Guide 3 →Rev D vs Rev C changes, transition gap assessment checklist, internal audit requirements, management review format, and Stage 1/Stage 2 registrar audit preparation for machining shops seeking initial certification or recertification.
