PPAP vs FAI is a comparison of defined review processes, not two interchangeable names for a sample measurement sheet. PPAP means Production Part Approval Process; FAI means First Article Inspection. For an aluminum-part order, confirm the applicable customer requirements before agreeing what the supplier must submit.
Both labels need their governing procedure, product identity and decision scope. A report can contain useful measurements while leaving required records or approval unresolved. Start with three checks: what process applies, what evidence is being submitted, and who authorizes the next step.
Separate these three statements
- “We received a report” describes receipt.
- “We reviewed the stated requirements” describes a scoped review.
- “The authorized customer approved the next step” requires the actual decision record.
1. PPAP vs FAI: confirm the requirement before quoting
AIAG’s public PPAP overview describes the process in terms of consistently meeting engineering design records and specifications during an actual production run at production rates. That description goes beyond the existence of one measured sample.
IAQG’s public 9102 overview describes standardized FAI process and documentation requirements for product verification. It identifies aviation, space and defense as the primary development context, while noting possible use in other sectors.
Those public descriptions introduce the subjects. They do not provide the complete requirements, forms or submission rules for your order. Obtain the applicable customer procedure and approved standard edition through the responsible quality team.
If a request says “FAI or PPAP report,” ask the customer to resolve the intended deliverable before supplier pricing. Name the governing process and document references rather than assume the two alternatives carry the same work.
Ask whether the customer requires one process, both, or a separately defined general sample review. Do not decide applicability from the customer’s industry name alone. Keep the agreed requirement attached to the actual order and part revision.
SAE’s public AS9102C scope states that its FAI requirements supplement customer and applicable statutory and regulatory requirements. A standard reference therefore does not remove the need to identify the customer’s requirements.
2. Compare the actual evidence package
For a PPAP vs FAI review, write the requested deliverables beside their controlling requirements. Keep the part identity, revision and represented manufacturing condition visible. A file named “approval report” does not establish its contents or scope.
Have the customer and supplier identify which records are required, who provides them and how they are submitted. State which entries are available, incomplete or awaiting a decision. Avoid treating an attractive dimension table as the whole package.
For a cutting-stage aluminum sample, distinguish the sawn blank from the final machined or finished part. Identify which requirements exist at the submitted stage and which remain downstream. The final drawing and the inspected stage should not silently be treated as the same condition.
Our first article inspection record guide organizes a general sample review around identity, requirements, manufacturing route, material evidence, results and disposition. It is a preparation guide; it does not replace an order’s formal requirements.
Inspection results still need their context
Ask which item each result belongs to, which feature was evaluated and which requirement governs its assessment. Keep the relevant method, units and supporting reference visible to the reviewer.
If the agreed submission needs evidence beyond dimensions, record those items explicitly. The responsible quality team should determine the appropriate records and acceptance basis. Do not manufacture a missing result or relabel an unresolved item as “not applicable” without the required authority.
For PPAP, retain the actual production-process evidence required by the customer. For FAI, retain the agreed first-article evidence and its governing scope. The purpose of this comparison is to locate the required records, rather than invent a universal shared checklist.
3. Identify the decision and what it allows next
When comparing PPAP vs FAI, keep evidence and disposition as separate entries. Ask who has authority to review the submission, who records the decision and what the decision permits. A supplier’s completion statement and the customer’s recorded disposition are different documents.
Retain the decision with the exact part, revision and submission identity. If an open item remains, identify its owner and the required resolution. Use the applicable customer process for proposed deviations rather than silently alter the drawing or scope.
An invented submission with an unresolved stage
Imagine aluminum part A17, revision C. The supplier sends dimensions for a cut blank and labels the file “approved sample.” The purchaser has requested a review of the finished component, including a later operation that has not yet been documented.
The fictional file may be useful evidence about the blank. Its label does not settle the final-part requirement or establish that the requested approval process is complete. The reviewer needs the missing stage and the authorized decision.
| Known in the example | Still to resolve |
|---|---|
| Blank dimensions received | Which submitted stage do they support? |
| Later operation required | Where is its required evidence? |
| File labelled approved | Who recorded the actual disposition? |
This is an original document-review example. It gives no actual measurement, accepted part, PPAP approval or FAI compliance claim.
Before the next delivery stage, request the recorded customer instruction where the applicable process requires it. Keep any permitted scope or conditions attached to that instruction. Do not infer unrestricted production or shipment permission from a sample photograph.
Write PPAP vs FAI requirements into the supplier comparison
Use a short order summary: governing procedure, part and revision, supplied stage, requested deliverables, review authority and required decision before the next step. Ask each supplier to confirm its included scope and identify exclusions.
Keep the work owners visible where more than one supplier is involved. A cutting supplier, machining supplier and final assembly owner may provide different records. Have the responsible quality team define how those records connect to the requested submission.
If the part, revision or manufacturing arrangement changes, ask which requirement governs the review of that change. Record the answer before carrying an older decision into the revised order. This article supplies no universal resubmission trigger or waiver.
PPAP vs FAI buyer questions
Can a dimensional report automatically replace PPAP?
Confirm the actual customer-required process and package. Report receipt alone is not a recorded approval.
Is every general sample review an AS9102 FAI?
No. Identify the agreed procedure and scope. A familiar report name does not establish compliance.
Does a formal submission label prove JiurunCut certification?
No. Ask for the actual applicable evidence and offered deliverables. This guide makes no certification claim.
State the cutting-stage evidence you need
Send JiurunCut the aluminum drawing, cut lengths and quantities, together with the applicable review requirements. Ask which cutting-stage records can be supplied for the proposal and keep formal customer approval responsibilities explicit.
