AS9102 Form 2 Product Accountability: The Materials, Special Processes, and Functional Testing Evidence That Has to Survive a Customer Reviewer

The First Article Inspection package leaves the supplier on a Tuesday. By Friday it comes back, and the rejection note from the customer SQE does not mention a single dimension on Form 3. The Form 1 signed cleanly. The drawing balloons reconciled to Form 3 one for one. The kickback is on Form 2. The chromate conversion source is not on the prime's approved processor list, the heat treat cert is for AMS 2759/4 but the drawing calls AMS 2759/2, and the material cert is for the bar stock heat that the supplier ordered for the next lot, not the bar stock heat that machined into the FAI part. Three lines on Form 2 just bought the supplier a partial FAI re-accomplishment and a six week slip on the qualification schedule.

This is the part of AS9102 that aerospace SQEs get wrong most often, and not because the form is hard to fill out. Form 2 is where the supply chain gets audited. Every material, every special process, every functional test on the drawing has to map to a supplier, a specification revision, and a cert number that the customer can pull and verify. The form is small. The evidence behind every cell is most of the FAI binder.

This post walks Form 2 from a reviewer's seat. What each cell is asking for under AS9102 Rev C, what the customer expects to see attached, the four kickback patterns that drive most of the rework, the NADCAP cross check that catches the most common gap, and a pre submission QA pass a supplier quality lead can run in an afternoon.

Where Form 2 Sits in the AS9102 Family

AS9102 Rev C, the active revision of the IAQG First Article Inspection standard, structures the FAI binder around three forms. Form 1 is Part Number Accountability and carries the top level identification, the FAI scope, and the signature block. Form 3 is Characteristic Accountability, the dimension by dimension verification of every drawing balloon. Form 1, Form 2, and Form 3 fit together as a single record, and the standard expects internal consistency across all three. Reviewers walk the three forms in sequence, and a discrepancy between them is a finding.

Form 2 sits between Form 1 and Form 3. Its job is to account for everything the drawing calls out that is not a dimension. Material specifications, special process specifications, and functional test specifications all live on Form 2. The cert evidence that proves the supplier met each spec lives behind Form 2 in the binder. Where Form 3 answers the question "did the supplier produce the geometry on the drawing," Form 2 answers the question "did the supplier produce that geometry out of the right material, with the right special processing, validated through the right functional tests, and can the customer trace the supply chain that did it."

A reviewer who is short on time will scan Form 1, walk Form 3 against the drawing balloons, and then spend the bulk of the review on Form 2 and the attached certs. The reason is simple. Form 3 has thousands of dimensions where a reviewer scans for outliers. Form 2 has on the order of ten to thirty lines, and each line is a high consequence accountability statement that a Stage 2 customer audit will probe. If the supplier got Form 3 wrong, the part is out of spec and the binder is rejected. If the supplier got Form 2 wrong, the supplier's quality system is in question, and that triggers a different kind of follow up.

What Form 2 Has to Carry Under AS9102 Rev C

Form 2 is organized into three required sections. The IAQG annex defines the field set, the AS9102 Rev C body text defines what each field has to carry, and customer flow downs commonly add fields beyond the IAQG floor.

The Materials Section

Every material called out on the drawing has to appear on Form 2 with the following fields populated:

• Material or process name as the drawing identifies it. "Aluminum 7075 T651 plate per AMS QQ A 250/12" is the kind of full callout a reviewer expects to see, not "Al 7075."
• Specification number including any revision suffix the drawing requires. AMS QQ A 250/12 Rev N is a different acceptance posture than Rev M. Cite the revision the drawing names, not the supplier's preferred revision.
• Code identification for any customer specific or proprietary material code. Boeing D6, Lockheed STM, Pratt PWA, Rolls Royce MSRR, and equivalent prime specific codes carry their own revision rules. If the drawing cites a prime code, the prime code revision is the controlling reference.
• Supplier (source) that produced the material. Not the supplier the FAI supplier bought it from in the distribution chain. The mill that produced the heat. The forge that produced the forging. The casting house that poured the cast. The Form 2 reviewer needs to walk from drawing callout to the source that actually performed the controlling process.
• Customer approval verification (if required by the customer flow down). Many prime customers require that the material source be on the prime's approved processor list and that the supplier cite the prime approval number, not just the AS9100 certification.
• Certificate of conformance number for the cert attached behind Form 2 in the binder.

Every line in the Materials section ties back to a material cert in the binder. The cert has to carry the heat lot or batch identifier that traces to the actual material that went into the FAI part. A material cert that lists a different heat than the heat the supplier consumed is not a defense. It is a fresh finding.

The Special Processes Section

Special processes are the operations on the drawing where the property of the finished part cannot be fully verified by inspection of the part itself. Heat treat, plating, anodizing, passivating, chemical conversion coating, painting, welding, brazing, nondestructive testing, and many surface treatments fall into this category. The drawing calls out a specification. The supplier has to demonstrate the operation was performed by a source approved to that specification.

Every special process called out on the drawing has to appear on Form 2 with:

• Process name as the drawing identifies it, with the customer or industry specification number and revision.
• Code identification if a prime customer specific process code applies.
• Supplier (source) that performed the operation. For most aerospace prime customers, this source has to be NADCAP certified for the specific commodity and to the specific specification the drawing names. NADCAP certification is not a blanket aerospace approval. A processor certified under NADCAP AC7102 for heat treat is approved for the heat treat commodity, but the scope statement on the certification specifies which alloy categories and which specifications the processor is approved to perform. A processor certified for AMS H 6875 carbon steel quench and temper is not by default approved for AMS 2759/2 aluminum solution heat treat. The Form 2 reviewer will cross check the cited source against the NADCAP eAuditNet database and confirm the scope statement covers the drawing specification.
• Customer approval verification for primes that maintain their own approved processor lists in addition to NADCAP. Boeing, Lockheed Martin, Pratt and Whitney, GE Aviation, Honeywell, Rolls Royce, Spirit AeroSystems, and the major engine and structures primes commonly require explicit prime approval, not just NADCAP. The approval number gets cited on Form 2.
• Certificate of conformance number for the cert attached in the binder. The cert has to show the lot or batch traceability that ties to the FAI part, the specification and revision actually performed, and the supplier's NADCAP and prime approval status at the time of the operation.

The Special Processes section is the source of more Form 2 rejections than the Materials section and the Functional Tests section combined.

The Functional Testing Section

Functional tests on the drawing are the acceptance tests that prove the finished part meets a performance requirement that goes beyond dimensional inspection. Pressure test, leak test, electrical continuity test, hardness test, conductivity test, tensile pull test on a sample bar, fatigue test on a sample bar, salt spray test on a coupon, and ultrasonic test of an internal feature all qualify. The drawing calls out the test specification and the acceptance criterion. The supplier has to demonstrate the test was performed against the cited revision, in an accredited or customer approved facility, with results documented.

Every functional test called out on the drawing has to appear on Form 2 with:

• Test name as the drawing identifies it, with the test specification number and revision.
• Acceptance criterion the drawing cites, exactly as cited. "Burst pressure 1500 psi minimum per ASTM B 962 paragraph 9.3" is the kind of full criterion citation reviewers expect.
• Supplier (source) that performed the test. For tests performed in house, the supplier is the FAI supplier and the supplier's accreditation status applies. For tests performed at a customer approved lab, the lab is the source and the lab's A2LA or equivalent accreditation status applies. NADCAP also maintains a test laboratory accreditation (AC7101) that some prime customers require in addition to A2LA.
• Certificate of conformance number for the test report attached behind Form 2.
• Test results numerical where the criterion is numerical. "Pass" is not an acceptable result for a numerical criterion. Cite the measured value.

The Functional Testing section is the smallest of the three sections by line count on most drawings, and it is the section most likely to be filled out from the test report rather than from the drawing. That order of operations is backward. The drawing calls the requirement. The test report is the evidence. The supplier has to enter the drawing requirement into Form 2 first and confirm the test report meets it, not enter what the lab reported and assume the drawing accepts it.

The Notes Section

The IAQG Form 2 annex includes a Notes field at the bottom of the form. Customer flow downs commonly require the supplier to use the Notes field to call out exceptions, additional traceability statements, customer waivers in effect, or qualifier statements about the cert evidence. Use it. The Notes field is one of the cheapest places to head off a clarification request from the reviewer, and a reviewer who reads a clear Notes statement on Form 2 is a reviewer who closes the form without sending an email back.

The Four Kickback Patterns That Drive Most Form 2 Rework

Across the FAI binders that come back from customer review, the rejections cluster into four patterns. A pre submission QA pass that explicitly checks for each one closes the bulk of the rework loop.

Pattern One: Material Cert Traceability Breaks at the Heat Lot

The Materials section cites a cert number. The cert is attached in the binder. The cert lists the supplier and the specification. The cert lists a heat number. The heat number on the cert is not the heat number that went into the FAI part. This is the most common Materials rejection and it almost always traces to a stock pull mistake on the shop floor. The supplier ordered material against the FAI program, the warehouse pulled from a different lot already on the shelf, the operator did not record the actual heat used, and the FAI cert is the most recent cert on file rather than the cert for the lot consumed. The fix is operational: lot control on the actual stock pulled for the FAI part, recorded at the time of cut. The Form 2 reviewer has no way to know about the floor process. They just see a heat number mismatch and reject the form.

Pattern Two: NADCAP Scope Does Not Cover the Specification

The Special Processes section cites a NADCAP approved source. The eAuditNet record confirms the source is NADCAP certified. The scope statement on the certification does not include the specification the drawing requires. AMS 2750 pyrometry is required for the heat treat process the drawing names, the source is NADCAP certified for AMS 2750 heat treat, but the supplier's drawing specification is AMS H 6875 and the NADCAP audit was performed against AMS 2759/4. These are different controlling specifications. The reviewer checks the scope and the form is returned.

The fix is supplier qualification, not Form 2. The supplier quality team has to maintain an approved special process supplier list that maps each drawing specification to a source whose NADCAP scope covers that specification, and the list has to be checked against eAuditNet before the order is placed, not after the cert comes back. This pattern is also why prime customer specific approved processor lists matter beyond NADCAP. The prime has already done this cross check and curated the list. Buying off the prime's list short circuits the scope problem.

Pattern Three: Cert Cited, Cert Missing or Wrong Cert

The Form 2 line cites a cert number. The reviewer flips to the cert section of the binder and the cert is not there, or a different cert is there with a different number, or the cert that is there does not cite the same specification revision Form 2 cites. This is the lowest hanging Form 2 reject and the most embarrassing one for the supplier. The fix is a literal cross check before binder submission. Read each Form 2 line, locate the cert in the binder, confirm the cert number matches, confirm the specification revision matches, confirm the supplier on the cert matches the source on Form 2. The exercise takes thirty minutes for most parts. Skipping it costs three weeks. The PPAP 18 elements checklist has the same pattern for automotive PPAP Element 7 Control Plan attachments. The discipline is the same.

Pattern Four: Functional Test Result Reported in the Wrong Units or Against the Wrong Acceptance Criterion

The Functional Testing section cites a test specification and a numerical criterion. The lab report reports the result in different units, against a different revision of the specification, or against an internal acceptance criterion that the lab uses for its standard customers rather than the criterion the drawing cites. Hardness reported as Brinell on the cert when the drawing called Rockwell C, conductivity reported as percent IACS on the cert when the drawing called megasiemens per meter, tensile reported per ASTM E8 Rev 21 on the cert when the drawing called Rev 16, all of these clear the lab's internal review and fail Form 2 reconciliation. The fix is upstream of Form 2. The supplier's test order to the lab has to specify the drawing revision, the controlling specification revision, the units, and the acceptance criterion verbatim from the drawing. The lab report then comes back in a form that reconciles to Form 2 without conversion.

The NADCAP and Prime Approval Cross Check

For aerospace primes, the Special Processes section of Form 2 is where the supply chain audit happens at FAI time. Every special process source has to be checked against both NADCAP scope and the prime customer's approved processor list, if the prime maintains one. The cross check is a five step exercise per source:

1. Pull the drawing specification and the specification revision the drawing requires. If the drawing references a prime specific code, also pull the controlling industry specification the prime code maps to.
2. Pull the NADCAP certificate for the proposed source from eAuditNet. Read the scope statement. Confirm the commodity, the alloy or material category, and the specifications listed cover the drawing requirement at the cited revision.
3. Pull the prime's approved processor list, if applicable. Confirm the proposed source is listed for the relevant commodity and for the program or part family. Some prime lists are program scoped and some are commodity scoped. The list scope matters.
4. Confirm the proposed source's NADCAP certification is in force on the date the operation will be performed. NADCAP certifications expire. A source whose cert lapsed between the order date and the operation date does not satisfy the AS9100 Clause 8.4.3 requirement for controlled external sources.
5. Document the cross check in the supplier qualification record so the Form 2 cert reference is supported by an internal approval record that predates the order.

A supplier quality team running this discipline upstream of every FAI is doing the work the customer would otherwise do at FAI review. The form passes on first read because the cross check already happened.

Form 2 Triggers for Partial FAI Re-accomplishment

Form 2 changes are one of the most common drivers of partial FAI re-accomplishment under AS9102 Clause 4. The standard names a lapse in production over a two year period as a re-accomplishment trigger, but the more frequent trigger in practice is a supply chain change that invalidates a Form 2 entry. The four Form 2 triggers worth tracking explicitly:

• Source change. A change in the supplier performing a material or special process operation triggers a partial FAI against the affected Form 2 line, with new cert evidence attached. The original FAI does not carry over the new source.
• Specification revision change. A new revision of a material, special process, or test specification, when the drawing pulls the new revision, triggers a partial FAI for the affected Form 2 line. The old cert was against the old revision.
• NADCAP or prime approval lapse. A source whose approval lapsed between the original FAI and the next production run requires a partial FAI on the next run, performed against a currently approved source.
• Drawing change that adds or removes a material, special process, or functional test. Any change that adds a new Form 2 line triggers a partial FAI for the added line. Any change that removes a Form 2 line triggers a Form 2 reissue to drop the obsolete line, even if no partial is required.

The discipline is the same as for dimensional changes. Identify the affected lines, scope the partial to the affected lines, document the impact analysis, and produce the partial Form 2 with cert evidence for the changed lines. The original FAI carries forward for unaffected lines.

The Pre Submission QA Pass on Form 2

A supplier quality lead can clear most Form 2 rejections with a thirty minute review pass before the binder leaves the building. The pass walks the form in this order:

1. Read every drawing callout the FAI scope covers. Material specifications in the title block, special process notes in the general notes block, functional test callouts on the body of the drawing, balloon notes that call additional specifications. Build a list. Every entry on the list has to appear on Form 2.
2. Walk Form 2 line by line and confirm each line traces to a drawing callout. Lines that do not trace get removed or moved to the Notes section as supporting evidence. Lines that should be there and are not get added.
3. For every Form 2 line, locate the cert in the binder. Confirm the cert number cited on Form 2 matches the cert in the binder, the specification and revision on the cert match the drawing, the supplier on the cert matches the source on Form 2, and any lot or heat traceability on the cert ties to the FAI part.
4. For every special process line, run the NADCAP scope cross check against eAuditNet for the source, and check the prime approved processor list if applicable. Confirm the source approval is in force on the date of operation.
5. For every functional test line, confirm the lab report reports the result in the units the drawing requires, against the revision the drawing cites, against the acceptance criterion the drawing cites.
6. Read the Notes section. Add any exceptions, qualifier statements, or customer waivers that would otherwise generate a clarification email from the reviewer.
7. Confirm Form 2 reconciles to Form 1. The FAI scope identified on Form 1 has to match the lines on Form 2. If Form 1 scopes the FAI to a single sub assembly, Form 2 lines have to cover only the materials, special processes, and tests relevant to that sub assembly.

A team that runs this pass against every FAI binder before submission catches most Form 2 rejections internally. A team that does not run it absorbs the rework loop on the back end.

Where Form 2 Becomes Tractable at Scale

Form 2 work is fundamentally accounting work. The drawing carries the requirements, the supply chain produces the evidence, and Form 2 reconciles the two. The work compounds at scale, because a multi part FAI program with shared material specs and shared special process sources can either run the cross check once and reuse it, or run it per part and absorb the duplication.

The Package module was built to keep Form 2 evidence tied to the part, the drawing revision, and the supplier qualification record so the cross check does not get rerun by hand for every FAI. Material certs, NADCAP scope confirmations, prime approval records, and functional test acceptance criteria all live against the source and the specification, and the FAI Form 2 pulls from those records rather than from the operator's memory. The same evidence stack supports PPAP for automotive customers running the same parts, where Form 2 evidence maps to PPAP Element 1 Design Records, PPAP Element 7 Control Plan supplier callouts, and PPAP Element 13 Material Test Results.

For the drawing side of the work, the same automated feature extraction that reads dimensions from the drawing for Form 3 also reads material specs from the title block, special process notes from the general notes, and functional test callouts from the body of the drawing. Blueprint Intelligence returns the drawing callouts as structured records, and the FAI process matches each callout to a Form 2 line and a cert. The error mode of the manual process, missing a callout buried in a balloon note or a sheet two general note, falls out.

For the upstream supplier qualification work, the same supplier records that feed supplier quality evaluation and the AS9100 Clause 8.4.3 audit evidence feed Form 2 source citations directly. The supplier qualification record and the Form 2 line are reading from the same source of truth.

Bottom Line

AS9102 Form 2 is small in size and large in consequence. Three sections, on the order of ten to thirty lines, and behind each line a cert that has to survive a customer reviewer flipping back to the cert section of the binder and walking the trace. The four kickback patterns, material cert heat lot mismatch, NADCAP scope mismatch, missing or wrong cert in the binder, and functional test reported in the wrong units or against the wrong revision, account for most of the Form 2 rework cycles in aerospace supply chains. Each is fixable by a discipline that lives upstream of the form. Lot control on the floor, approved processor list curated against NADCAP scope, a thirty minute pre submission QA pass against the binder, and a test order to the lab that cites the drawing requirement verbatim.

Form 2 is also the FAI form that connects most directly to the rest of the quality system. The supplier qualification records feed Form 2 sources. The NADCAP scope cross check feeds AS9100 Clause 8.4.3 control of externally provided processes. The functional test acceptance criterion cross check feeds AS9100 Clause 8.5.1.3 verification of validation activities. A supplier whose Form 2 passes on first read every time is a supplier whose quality system is working at the supply chain layer. A supplier whose Form 2 keeps coming back has a supply chain layer problem masquerading as an FAI problem. The fix is at the supply chain layer, not the form.

For the broader FAI structure, see how Form 1, Form 2, and Form 3 fit together under AS9102 Rev C and characteristic accountability on Form 3. For the trigger logic that drives partial FAI when a Form 2 line changes, see AS9102 partial FAI re-accomplishment. For aerospace suppliers also running PPAP on the same parts, FAI vs PPAP walks the reconciliation. For the audit clauses that sit behind Form 2 in an AS9100 system, AS9100 clause by clause audit readiness walks the evidence the certification body looks for. For the parent audit checklist, the AS9100 internal audit checklist covers the internal audit cadence that catches Form 2 gaps before the customer sees them.
