AS9100D Plain-English Clause Guide

AS9100D is written for people who already speak standards. If you run quality at a 15-person machine shop, you need to know what a clause means for your shop, what the auditor will ask to see, and where shops like yours usually get caught.

This 33-page PDF walks through every clause from 4 to 10. For each one you get:

What it asks, in plain words

What auditors check, and how they sample

Evidence to have ready: the records and documents that answer the question

Common small-shop findings

Aerospace additions, marked in their own box so you can see what AS9100D adds on top of ISO 9001

Which NQT kit helps, if you want forms and templates for that clause

It also includes:

How AS9100D is put together, and where things stand in October 2026: the 2024 climate change amendment and the status of the next revision

How certification auditors work

A one-page clause-to-record cross-reference

Where to buy the official standard
