This checklist groups the usual flowdown items so purchase orders are complete before they go out. **Sections:** #### How to use the checklist **Body:** Walk through the groups for a typical PO or for your standard terms and conditions. Tick each item that is covered and note where it lives, for example PO text, attached quality clauses or a quality agreement. Items marked critical are the ones that cause audit findings or escaped nonconformances most often. Export the ticked list as evidence of your flowdown review. #### Why flowdowns matter **Body:** Your customer's requirements pass down to you, and you must pass the relevant ones down to the people who make, process or test product for you. An unflowed special process approval requirement, for instance, can lead to parts processed at an unapproved source and a costly rework or escape. #### Where flowdown text lives in the ERP **Body:** Good practice is to hold standard quality clauses as controlled text blocks in the ERP and attach them by supplier category or part risk. That avoids buyers retyping requirements. Keep a revision history, since the clause version in force at order time may matter later. #### Common mistakes **Body:** Citing a specification without its revision, relying on a generic terms page that the supplier never acknowledged, and failing to flow to sub-tier providers are typical. Regulatory clauses should be reviewed by your contracts or legal team. **Cta:** We can help check POs against flowdown rules inside your ERP and flag missing clauses before release. **Faq:** #### Is this the full AS9100 8.4.3 list? **Answer:** It is a practical interpretation. The licensed standard lists the information to communicate. Add customer and program specific items on top. #### Do I need a quality agreement as well as a PO? **Answer:** Not always, but many organizations use a quality agreement for recurring suppliers and reference it on POs. Either route can satisfy the requirement if requirements are clear. #### Which items are mandatory? **Answer:** Mandatory items depend on the contract and standard. The critical flags show items that commonly drive findings, not a legal definition. #### Who should review regulatory clauses? **Answer:** Contracts or legal staff. Export control and government clauses have legal consequences and should not be improvised by buyers. ## Search terms AS9100 flowdown checklist, aerospace purchase order flowdown, AS9100 8.4.3 information for external providers, supplier flowdown requirements, aerospace PO clauses checklist, DFARS flowdown checklist --- Talk to an engineer: https://netray.co/contact?intent=erp_ai | Machine catalog: https://netray.co/agent/catalog.json
