Boeing supplier requirements · Form X31764
It usually arrives as one line in a customer's quality notes — “supplier shall comply with Boeing Form X31764” — with no explanation. X31764 is Boeing's Quality Purchasing Data Requirements for Boeing Commercial Airplanes and Boeing Global Services: ten pages of quality terms added to Boeing's supply contracts, some of which Boeing's suppliers are required to pass on to theirs.
If you are several tiers down, the question is not “what does X31764 say” but “which parts of it are now mine”. This page answers that. Written by a practicing aerospace QMS auditor, from Boeing's published form — paraphrased, not reproduced.
The short version
Look for the words “Flow-down to Supply Chain”. Boeing marks the items its suppliers must pass on. Those are the ones that reach a sub-tier.
The certification requirement is not one of them. X31764 on its own doesn't make a sub-tier get AS9100. Your customer's own terms might.
Four items catch small shops: first article inspections in Net-Inspect, the three-business-day escape notice, approval before moving work, and using Boeing-approved special processors where the spec requires them.
Where it stands: as of 24 September 2026, Boeing's supplier quality page links to the revision dated 5 January 2026. Revisions dated 8 August 2025 and 1 January 2024 are still easy to find through a search engine, and they differ — check the revision date printed on whatever copy you have. Your purchase order decides which revision you are held to.
How it fits together
D6-82479 is Boeing's quality-system requirement: which aerospace standard a supplier must be certified to and what Boeing expects on top. X31764 is the purchasing-data form that invokes it. Section 1 of X31764 requires Boeing's supplier to hold accredited certification under the IAQG scheme — 9100, 9110 or 9120, per the matching D6-82479 appendix — and adds 9103 and 9115 where D6-82479's addenda apply. D6-82479, in turn, tells suppliers to comply with X31764 when the contract calls for it.
The rest of X31764 is general business and production requirements (Section 2), requirements that depend on the work you do (Section 3), and a short section specific to Boeing Global Services spares (Section 4).
If you're a sub-tier
These are the items marked for flow-down in the 5 January 2026 revision. Several apply only if you do that kind of work — a shop that never touches Boeing's digital product definition can ignore that line.
| Item | What it asks, in plain terms |
|---|---|
| 1B | Acceptance authority media — your inspection stamps and e-signatures. Pass the requirement down, and be able to show your people were told that misusing a stamp is a breach of federal regulation |
| 2a | Provide quality and engineering data in English, on the media Boeing specifies, when asked |
| 2h | Get Boeing's written approval before transferring work (Boeing form X35781) |
| 2i | First article inspection to 9102, completed in Net-Inspect, and no shipping until it's done |
| 2j | A FOD prevention program to AS9146 |
| 2k | Excess inventory must trace back to the Boeing order that authorized making it; previously rejected stock needs written permission |
| 2m | Where Boeing specifications require an approved processor, use one from Boeing's approved process sources, D1-4426 |
| 3a | Boeing digital product definition capability approval, D6-51991, if you work from Boeing's models |
| 3b | FAA Form 8130-9 statements of conformity, if you're authorized to complete them |
| 3c | Delegated product release to AS9117, if verification is delegated |
| 3d | Clad aluminum exterior skins inspected to D6-85354, if you supply them |
| 3e | Operator self-verification to AS9162, if you use it |
| 3i | Report a potential or known nonconformance escape within three business days of discovering it |
What does not flow down
Section 1(a) — the requirement to hold accredited AS9100, AS9110 or AS9120 certification — is not marked for flow-down. Neither are corrective-action reporting timelines, source-inspection quality rates, or the 4:1 measurement tolerance ratio. Those bind Boeing's direct supplier.
That matters if you hold ISO 9001 and supply aerospace customers without an AS9100 certificate. X31764 alone does not change that. But two things can: your customer's own purchase-order terms, which can require whatever they like, and D6-82479, which asks your customer to pick its manufacturing sub-tiers on their ability to conform to 9100. Expect to be asked for evidence of a 9100-capable system, certificate or not. More on ISO 9001 shops supplying aerospace →
Where small shops get caught
An AS9102 first article report on paper or in a spreadsheet is not enough. For supply-chain FAIs completed on or after 1 January 2024, X31764 says Forms 1, 2 and 3 are completed in Net-Inspect and made available to Boeing — by you or by your customer. Agree which of you enters it before the first part is cut. And product doesn't ship until the FAI requirements are complete.
The clock starts on the day a potential or known escape is discovered — not when the investigation concludes. That means someone needs the authority to notify on suspicion, and a defined route to your customer. Your customer has the same three days to reach Boeing, so it is reasonable to expect them to want to hear from you sooner.
Transferring work needs Boeing's written approval before it starts, and the requirement flows down. Ask your customer what counts as a transfer for their orders before you move a job to another building, machine cell or subcontractor — not after.
Where a Boeing specification calls for an approved processor — heat treat, plating, NDT and the like — it has to be one listed in D1-4426, and that requirement flows too. The easy way to get this wrong isn't choosing an unapproved processor on purpose. It's a processor whose approval has lapsed, or a one-off substitute when the usual one is backed up.
If it just landed on your desk
How JBird does it
This advice holds however you run your quality system. It is also why JBird keeps the terms you flow to suppliers as one maintained document, with a per-supplier record of how and when it reached them, which is what clause 8.4.3 asks you to be able to show. Acceptance authority media has its own register, and first article inspection has its own record, rather than living in a shared drive.
Common questions
X31764 is Boeing's Quality Purchasing Data Requirements for Boeing Commercial Airplanes and Boeing Global Services. It adds quality requirements to Boeing's supply contracts: certification, acceptance stamps, first article inspection, FOD prevention, approved process sources, nonconformance notification and more. Items marked Flow-down to Supply Chain must be passed on to sub-tier suppliers.
Not by itself. The certification requirement in Section 1 is not one of the items marked for flow-down. Your customer can still require certification in its own purchase order terms, and Boeing's D6-82479 asks your customer to select manufacturing sub-tiers on their ability to conform to 9100. Read your purchase order for what actually applies.
In the revision dated 5 January 2026: acceptance authority media, English-language data, work transfer approval, first article inspection including Net-Inspect, FOD prevention to AS9146, excess inventory traceability, Boeing approved process sources (D1-4426), digital product definition, FAA Form 8130-9, AS9117 delegated release, clad aluminum skins, operator self-verification to AS9162, and nonconformance escape notification.
Within three business days from the day a potential or known escape is discovered. The item is marked for flow-down, so your customer is likely to want to hear from you sooner, since the same clock runs for them.
As of 24 September 2026, Boeing's supplier site links to the revision dated 5 January 2026. Earlier revisions dated 8 August 2025 and 1 January 2024 still circulate online, so check the date on the copy you are reading.

Pilot program
45 modules are already built and working. Pilot organizations get the system at no cost during development, direct input on what gets built next — there is a Report a Problem button on every screen, and it goes to a register we work through — and a migration path when the IA9100 revision lands.
