AS9102 Forms Explained: Practical Guide to Forms 1, 2, and 3 for Aerospace Suppliers

AS9102 first article inspection depends on three core forms: Form 1, Form 2, and Form 3. Together, these AS9102 forms document what article was inspected, what materials and processes were used, and whether every required design characteristic was verified.

This article explains what each form is for, what evidence belongs with it, and where aerospace suppliers usually make mistakes that lead to FAIR rejection, rework, or delayed customer approval. The focus is AS9102C, the current version of the AS9102 standard, which was released on June 28, 2023.

A first article inspection is a production part verification process that ensures products meet design specifications and requirements before full-scale production begins. A first article inspection report, often called a FAIR, is the documented report package that shows the work was completed and the requirements were met. In practical terms, the three AS9102 forms and their attachments become the first article inspection fai package submitted to an OEM, Tier-1 customer, or regulated MRO customer.

AS9102 was developed by the International Aerospace Quality Group (IAQG) and is published by SAE International. The standard establishes a consistent, globally recognized framework in the aerospace and defense industries for conducting a First Article Inspection (FAI). Connect 981 supports this work by digitizing AS9102 workflows, but this guide is primarily educational: it is written for suppliers that need to get the documentation right the first time.

Fast Answers: What Each AS9102 Form Is For

• Form 1 is Part Number Accountability. It identifies what part, assembly, or subassembly is being inspected, including part number, revision, drawing identifiers, purchase order information, and linked FAIRs.
• Form 2 is Product Accountability. It documents materials, process specifications, special processes, finishes, and functional tests required by the drawing, model, specifications, or customer contract.
• Form 3 is Characteristic Accountability. It records all product characteristics, including dimensions, tolerances, GD&T, drawing notes, finish callouts, and inspection results.
• The AS9102 standard establishes documentation requirements for the First Article Inspection (FAI) process, which includes three forms: Form 1 for Part Number Accountability, Form 2 for Product Accountability, and Form 3 for Characteristic Accountability.
• The AS9102 standard outlines three forms for documenting the FAI: Form 1 for Part Number Accountability, Form 2 for Product Accountability, and Form 3 for Characteristic Accountability.
• The three forms together provide traceability from the part number to material and process evidence to measured characteristics.
• Incorrect or incomplete information on any one form is a frequent root cause of fair rejection, rework, and delayed approval from aerospace customers.

In aerospace, quality assurance forms serve as a roadmap and birth certificate for manufactured parts, offering critical quality assurance benefits. AS9102 forms also ensure supply chain traceability, traveling with parts to allow investigation of failures by linking them to materials and manufacturing processes used.

AS9102 Form 1 – Part Number Accountability

Form 1 documents what article is being inspected in the first article inspection. That article may be a detail part, an assembly, or a subassembly. Form 1 ties the FAIR to specific part numbers, drawing revisions, model definitions, customer purchase orders, and related lower-level inspections.

Form 1 is the cover sheet of the article inspection report. OEM quality teams and auditors use it to quickly understand what the first article inspection report covers and how the inspected article relates to the engineering definition. If Form 1 is wrong, the customer may not trust the rest of the report.

AS9102C, released on June 28, 2023, is the current version. AS9102B was released on October 6, 2014, and AS9102A was released on January 13, 2004. Current submissions should follow the C layout when AS9102C is required, although legacy FAIRs may still exist in older AS9102A or AS9102B formats.

Typical Form 1 data includes:

Form 1 item

What it controls

Part number and part name

Confirms the article being inspected

Drawing number and drawing revision level

Connects the FAIR to the engineering definition

FAI report number or FAIR identifier

Provides a unique tracking reference

FAI type

Identifies full FAI, partial FAI, or re-inspection scope

Organization name and CAGE code

Identifies the supplier organization

Purchase order number

Links the inspection to the customer contract

FAI completion date

Shows when the inspection was completed

Reviewed and approved fields

Records the responsible person or people for FAIR approval

Nonconformance indication

Identifies whether documented nonconformances are included

Form 1 of AS9102 requires identification of the part and associated sub-assemblies, while Form 2 must account for all material and process specifications, including any special processes and functional testing defined as design requirements. For assemblies, Form 1 should identify the higher-level assembly and list the associated sub assemblies or lower-level parts. If those sub-assemblies have their own first article inspection fai submitted separately, the related FAIR identifiers should be listed or referenced.

Evidence that belongs with Form 1 includes:

• Engineering drawings or model definition matching the part number and revision.
• Bill of material or configuration list for assemblies.
• Applicable change notices, such as ECPs, ECOs, ECNs, or customer-approved deviations.
• Purchase order and contract documents that confirm part number, revision, quantity, and customer requirements.
• Customer approvals when the customer controls the part number, drawing, or revision.

Common Form 1 mistakes include:

• Part number, dash number, or suffix does not match the latest purchase order.
• Drawing revision on Form 1 does not match the attached drawings or model-based definition.
• Part name or drawing number is inconsistent between Form 1 and the engineering package.
• FAI type is marked as full when only partial article inspection was performed after a minor change.
• Partial FAI is selected but the reason for the partial FAI is missing or weak.
• Related lower-level FAIRs are not listed for multi-level assemblies.
• PO or contract number is incomplete, making customer traceability difficult.

In practice, many of these errors are transcription problems. A digital platform like Connect 981 can reduce the risk by auto-populating Form 1 from ERP, MES, and PLM data. The useful control is simple: part number, revision, PO, and drawing information should come from governed source systems rather than being typed repeatedly into spreadsheets.

AS9102 Form 2 – Product Accountability (Materials, Processes, and Functional Tests)

Form 2 documents the article’s material specifications, special processes, finishes, and functional tests. This is often where aerospace suppliers run into the most documentation gaps because the evidence may come from mills, distributors, outside processors, internal test teams, or customer-furnished material records.

Product accountability means proving that all required material, process, and functional test requirements in the drawing, model, specifications, and customer contract have been correctly applied and verified. The form is not just a list of suppliers. It is the bridge between engineering requirements and the actual materials and processes used to produce the article.

Key Form 2 categories usually include:

• Raw material specifications, such as AMS, MIL, EN, ASTM, or customer-specific standards.
• Material type used, including alloy, temper, condition, heat number, lot number, or batch reference.
• Special processes such as heat treat, NDT, shot peen, welding, brazing, anodizing, passivation, coatings, and plating.
• Standard manufacturing processes when they have explicit specification callouts.
• Functional and performance tests, such as proof load, pressure, electrical, torque, leakage, environmental, or operational tests required at the first article inspection stage.

Evidence that belongs with Form 2 includes:

Category

Evidence to attach or reference

Raw materials

Mill certificate or distributor certificate with heat or lot number matching the part or batch

Special processes

Certificate of Conformance, process results, processor name, approval status, and exact specification revision

Functional testing

Test report or results summary tied directly to the FAI unit or lot

Test equipment

Calibration certificate where equipment status must be verified

Customer-furnished material

Records showing receipt, identity, and use of the furnished material

A common example is plating. If the drawing requires a specific plating specification and revision, the Form 2 entry should reference the exact specification and the supplier certificate should show the same requirement. A generic note such as “per customer spec” is not enough. If the drawing requires AMS 2411 Rev E and the certificate references AMS 2411 Rev C, the customer will likely reject the FAIR or require clarification.

AS9102C removed the signature field on Form 2 that existed in AS9102B. One of the significant changes from AS9102B to AS9102C includes the removal of the signature field in Form 2 and Form 3, which has been renumbered as a result. Overall review and approval are handled through the designated approval fields, primarily on Form 1.

Common Form 2 mistakes include:

• Missing material certificate or certificate that lacks heat or lot traceability.
• Outdated specification revision listed on Form 2.
• Processor certificate not traceable to the part number, PO, serial number, or lot.
• Special process provider not approved by the customer where approval is required.
• Functional tests performed but results are not summarized clearly.
• Test results are attached but not tied directly to the first article unit.
• “Per customer spec” notes are used without a document number and revision.
• Confusion about when a special process needs its own FAIR versus when a detailed Certificate of Conformance is sufficient under AS9102C Section 1.3.

Build-to-print parts usually have direct drawing and specification callouts that drive Form 2. Build-to-spec work and repair or overhaul work can be more layered. In MRO environments, Form 2 may need to reflect OEM requirements, maintenance manual requirements, repair scheme requirements, and customer-specific instructions. The constraint is not only whether the process was performed. The supplier must show that the correct requirement was identified and verified.

A connected operations layer like Connect 981 can centralize material certs, special process CofCs, and test reports. That makes Form 2 population faster, but more importantly, it makes audit retrieval practical when a customer asks for evidence months or years later.

AS9102 Form 3 – Characteristic Accountability, Verification, and Compatibility Evaluation

Form 3 is where every design characteristic is listed, ballooned, and matched to actual inspection results for the first article. It is the most detailed part of the first article inspection report and the place where customers often spend the most review time.

Form 3 of AS9102 mandates that all product characteristics, such as dimensions and tolerances, must be documented, and an inspection drawing or model is required to clearly identify these characteristics with uniquely numbered inspection balloons. This includes dimensions, GD&T, datum references, drawing notes, finish callouts, marking requirements, thread requirements, and other characteristics defined by the engineering package.

Suppliers typically use ballooned drawings or annotated 3D models:

• Each design requirement receives a unique balloon or characteristic number.
• The balloon number corresponds to a characteristic number on Form 3.
• The requirement is recorded with the nominal value, tolerance limits, or specification reference.
• The measured result, pass/fail result, or “verified by test” result is entered in the same row.
• Nonconforming results are identified and linked to an NCR, concession, deviation, or customer disposition.

Typical Form 3 row content includes:

Form 3 row item

Purpose

Characteristic number

Ties the row to the ballooned drawing or model

Reference location

Identifies sheet, zone, view, section, model element, or PMI feature

Requirement

Records dimension, tolerance, GD&T symbol, finish, or note

Nominal and tolerance limits

Defines the acceptance range

Result

Shows actual measured value or verified test outcome

Inspection method

Identifies CMM, calipers, thread gage, go/no-go gage, visual inspection, or test method

Nonconformance field

Indicates whether the result failed and links to disposition

Additional data or comments

Provides needed clarification without replacing objective results

The discipline here is coverage. “All characteristics” means more than major dimensions. It includes critical notes, general tolerance requirements, special marking, surface finish, thread callouts, sealant notes, and requirements embedded in digital product definition.

AS9102C removed the per-form signature column from Form 3 as well. The standard now emphasizes clear recording of inspection results and dispositions rather than multiple signature blocks on every form. The signature and approval control is consolidated through the required FAIR review and approval process.

Common Form 3 mistakes include:

• Missing characteristics because drawing notes or flags were not ballooned.
• Combining multiple distinct requirements into one row, making traceability unclear.
• Recording “OK” or “PASS” instead of actual measured values where numeric results are required.
• Using sampling when the customer or AS9102 requires 100 percent verification for the first article inspection fai.
• Failing to update Form 3 after engineering changes between prototype runs and the current FAI run.
• Missing inspection method or tool information.
• Not documenting the source of tolerances derived from general notes, title block tolerances, or company standards.

AS9102C emphasizes the inclusion of verification against digital specifications, such as multi-dimensional CAD files, which was a notable advancement in the standard. For model-based definition, verification evidence may include CMM programs referencing the 3D model, PMI-linked inspection plans, digital clearance checks, or software-based tolerance analysis. The evidence can be digital, but it still must be traceable to each recorded characteristic on Form 3.

Connect 981 can link Form 3 rows directly to inspection plans, in-process checks, CMM output, and defect records. The value is not only fewer keystrokes. The value is maintaining a controlled audit trail from the ballooned requirement to the actual result and any nonconformance disposition.

How the Three AS9102 Forms Work Together in a First Article Inspection Report

A complete first article inspection report includes all three AS9102 forms plus supporting evidence: drawings, models, certs, test reports, calibration records when applicable, and nonconformance records. The report should show that the production run used to create the FAI article was controlled, understood, and capable.

An AS9102 First Article Inspection Report (FAIR) ensures that the production process is stable, repeatable, and capable of conforming to strict safety standards. It is not required for every batch. AS9102 FAIRs are triggered by new parts, design changes, process shifts, new suppliers, or extended inactivity of a part.

The logical flow is straightforward:

• Form 1 defines the part, assembly, or subassembly being inspected and connects the FAIR to related lower-level FAIRs.
• Form 2 proves that all material, process, and functional requirements have been met.
• Form 3 proves that all design characteristics have been verified and recorded.

Each AS9102 form contains universal identifiers for traceability, repeated across forms to facilitate tracking of inspections. These identifiers typically include part number, FAIR identifier, drawing revision, organization data, and other control information that allows the customer to connect the forms into one coherent package.

This structure supports AS9100D Clause 8.5.1.3 on production process verification. AS9102 first article inspection provides a standardized way to demonstrate that the manufacturing process can produce conforming parts across the aviation, space, and defense supply chain.

Aerospace customers use the article inspection report to establish baseline capability, approve suppliers for ongoing production, and support future audits or investigations. When a field issue occurs, the FAIR helps quality and engineering teams trace the article back to its drawings, materials, process certificates, inspection results, and any disposition records.

Digital traceability across all three forms is increasingly expected, especially when organizations work with multi-dimensional CAD models, complex assemblies, and supplier tiers spread across multiple companies. Connect 981 can act as a unified layer between ERP, MES, QMS, PLM, and supplier systems so the data needed for all three forms is consistent, up to date, and available without hunting through emails and shared folders.

Common Supplier Mistakes That Cause AS9102 FAIR Rejection or Rework

Many FAIRs are rejected not because the parts are bad, but because the documentation is incomplete, inconsistent, or not aligned with AS9102C expectations. The product may meet the requirement, but if the evidence is weak, the customer still has a problem.

FAI is typically required when there is a change in design, production process, or when a new supplier is introduced, ensuring that all aspects of the production process are verified. A new or revised part, a tooling change, a process relocation, or a long production gap can all trigger the need to conduct a full or partial FAI before the part moves into full production.

Common rejection themes include:

Configuration and revision control issues

• A previous FAI template is reused and the drawing number or revision is not updated on Form 1.
• The PO calls one drawing revision while the FAIR references another.
• Model-based definition and PDF drawings are not aligned.
• The part number suffix is omitted, which changes the actual configuration being inspected.

Incomplete coverage of requirements

• Ballooning covers dimensions but ignores drawing notes.
• Surface finish, marking, torque, sealant, or packaging requirements are skipped.
• Form 2 lists heat treatment but does not attach the processor certificate.
• Form 3 does not include characteristics derived from general tolerance notes.

Weak traceability

• Material certs are attached but do not show the heat or lot used for the FAI part.
• Special process certs do not reference the part number, PO, serial number, or lot.
• Functional test reports are included but do not identify the FAI unit.
• A contact person is listed, but the responsible organization cannot provide the backup evidence during review.

Poor measurement recording

• “OK” is entered where a numeric measured value is required.
• Inspection methods are missing.
• Nonconforming results are not linked to an NCR or concession.
• Sampling is used without customer approval or without a defined basis.

The impact is predictable: repeated customer feedback loops, additional review time for quality engineers, delayed release into the first production run or ongoing production run, and avoidable pressure on program schedules.

Standardized templates, training, and digital workflows reduce this risk. The goal is not to make the paperwork prettier. The goal is to ensure every required field is completed, every attachment is present, every revision is current, and every result is traceable before submission.

A typical aerospace supplier moving from spreadsheet-based FAIRs to a digital article inspection workflow can use Connect 981 to enforce required fields, compare drawing revision data against ERP and PLM, flag missing certificates, and check that Form 3 balloon counts match recorded rows before the FAIR goes to the customer.

Making AS9102 First Article Inspection Digital and Audit-Ready with Connect 981

The form-by-form discipline matters, but the larger operational problem is data continuity. Aerospace suppliers often manage FAIR evidence across ERP records, MES travelers, QMS nonconformance logs, supplier emails, shared folders, CMM files, and paper inspection sheets. That fragmentation creates risk.

Connect 981 is built as an aerospace operations platform for connected shopfloor execution, supplier collaboration, and compliance-ready documentation. For AS9102 forms, the platform supports:

• Preconfigured templates aligned to AS9102C Forms 1, 2, and 3.
• Automatic population of part, drawing, and revision data from ERP or PLM into Form 1.
• Central repository for material certs, special process CofCs, and test reports feeding Form 2.
• Integration with inspection stations and CMM output to populate Form 3 with measured results.
• Digital work instructions and version control for the routing used to produce the FAI article.
• Defect logging and nonconformance linkage when results are out of tolerance.
• Supplier workflow integration so external processors and sub-tier suppliers provide evidence in a controlled process.

For operations leaders, manufacturing engineers, quality managers, and supply chain teams, the outcome is practical:

• Reduced FAIR cycle time and fewer customer rejections.
• Consistent article inspection practices across factories and suppliers.
• Audit-ready traceability for AS9100, FAA, EASA, ITAR, and customer-specific requirements.
• Better visibility into documentation readiness before a part reaches customer review.
• Faster investigation when a material, process, or inspection issue is identified.

Connect 981 can be used for both production FAIs and MRO-related first article inspections when new repair routes, repairs, or modifications are introduced. The platform’s low- and zero-code workflow builder lets teams adapt AS9102 templates for customer-specific FAIR formats without relying on heavy custom IT projects.

To see how this works in practice, request a demo of Connect 981 and review a live digital AS9102 first article inspection workflow from drawing ballooning through FAIR submission.

Where to Go Next: Broader AS9102 and FAI Resources

This article focused on the three AS9102 forms and the documentation mistakes that commonly create rework. Teams that need broader guidance should also review when FAI is required, how full and partial FAI decisions are made, and what re-inspection triggers apply after a change.

Useful next resources:

• Read a broader What is AS9102 First Article Inspection? guide covering when FAI is required, full vs partial FAI, and re-inspection triggers.
• Use an article inspection checklist for aerospace suppliers to prepare drawings, certs, test reports, and approvals before customer submission.
• Review Connect 981 resources for example AS9102 templates, digital FAIR dashboards, and supplier-ready inspection workflows.
• Verify the current revision before finalizing FAIR templates. AS9102C was released on 2023-06-28, and customer-specific requirements can evolve beyond the baseline standard.
• For the source standard, confirm requirements through SAE International’s AS9102C publication.

Mastering as9102 forms turns first article inspection from a paperwork burden into a repeatable process. With clear documentation, disciplined revision control, and the right digital workflow, suppliers can provide better evidence, reduce customer rework, and support quality and on-time delivery.
