First article inspection (FAI) is a formal verification performed on a production-representative sample from the first production run—not necessarily the very first unit —to confirm it matches customer specifications, engineering drawings, and purchase order (PO) quality clauses. In practice, the sample is randomly selected from the initial lot and measured against defined design characteristics using calibrated equipment.
FAI acts as a checkpoint within the broader quality management system (ISO 9001/AS9100), confirming that the manufacturing process can produce conforming parts before full-scale production begins.
It typically precedes and supports other product inspection stages and control plans. Two core scopes exist: Full (standard) FAI for new parts, new suppliers/facilities, or long production lapses; and Partial/Delta FAI when only specific characteristics or processes change.
Primary users include aerospace & defense (AS9102-driven), automotive (within APQP/PPAP), medical devices (ISO 13485), electronics/electrical, precision machining, and molded plastics, where GD&T, special processes, and traceability are critical. FAI pauses production for review; pass results allow release, while fails trigger root cause, corrective actions, and a re-inspection.
What is the first article inspection (FAI)?
FAI is a formal verification that a manufacturing process consistently produces parts conforming to design intent by comparing a production-representative unit’s dimensional, material, functional, and visual characteristics to engineering documentation and contract specifications.
Reference documents include drawings/CAD (DPD), BOM, applicable specifications, and PO quality clauses; measurement results are logged with gage traceability, documented tolerances, and units.
FAI validates the process, not full process capability; it creates objective records and clear accountability through a First Article Inspection Report (FAIR) used for acceptance and traceability, including part number accountability, materials/product accountability, and characteristic accountability mapped to a ballooned drawing.
By understanding how FAI verifies each design and process detail, you can better see why its implementation offers measurable benefits across quality, cost, and compliance
What are the benefits of first article inspection?
FAI reduces defects and rework, verifies manufacturability, and strengthens customer confidence before full-rate production. There are 10 advantages:
- Reduce scrap/rework by catching dimensional, material, and functional deviations early in the production run.
- Validate manufacturing process setup and s pecial processes (e.g., heat treat, anodize) against specifications.
- Ensure compliance with customer/industry standards (e.g., AS9102, ISO 13485) and contract requirements.
- Provide traceability via FAIR, ballooned drawings, gage IDs, and work-order/serial linkages.
- Accelerate customer or source-inspector approval and release to production.
- Confirm measurement system integrity (calibration due dates, resolution adequacy, measurement system analysis needs).
- Identify design ambiguities and enable DFM feedback before mass production.
- Mitigate supply risk when changing materials, tools, suppliers, or manufacturing locations.
- Support audits and long-term record retention obligations (multi-decade in the aerospace industry).
- Enable digital-thread usage (CAD-integrated ballooning, automated data capture, searchable process flow diagrams).
When should a first article inspection be performed?
Perform an FAI at initial production of a new or revised part and whenever fit, form, or function could be impacted. Start with the broad triggers: new product introduction; engineering change (revision/part number); process change that shifts manufacturing capability (e.g., 4-axis CNC to Swiss lathe, laser cutting to stamping—requiring a Full FAI); material or specification change; tooling/equipment change or refurbishment; supplier or manufacturing facility transfer; resuming production after a significant lapse (commonly ≥2 years); explicit customer request; or other risk-based cues in your quality control plan.
Timing matters: in regulated sectors, FAI typically executes after the first production run has begun, sampling randomly from the first batch to prevent scale-up issues. Many aerospace programs position FAI very early—when roughly 1–10% of the order is produced—to catch systemic problems before cost and schedule escalate. When only specific characteristics or processes changed, conduct a Delta (Partial) FAI; otherwise, complete a Full FAI to re-establish the baseline and protect downstream lots in the supply chain.
What types of first article inspection are there?
First article inspection types align to risk and scope, ensuring your inspection process fits the situation. Full (standard) FAI covers all characteristics for new parts, new suppliers or facilities, or after long gaps; Partial/Delta FAI limits checks to changed characteristics or processes while confirming no unintended side effects.
Piece-part/Component FAI focuses on a single detailed component, while Assembly FAI validates assembled items and links back to component FAIRs for vertical traceability. Interim FAI is time-boxed between milestones to de-risk ramp-up on high-risk features.
Selection hinges on whether change affects fit-form-function, special processes, or interfaces. For assemblies, the FAIR must reference sub-assemblies and list each subcomponent FAIR number and serial (if serialized). These approaches are routine and often contractual in aerospace/defense (AS9102), frequently embedded within APQP/PPAP in automotive, and used for verification under ISO 13485 in medical devices—all reinforcing quality assurance, documentation control, and compliance across industries.
Full (standard) first article inspection
A Full FAI is a comprehensive verification of all design characteristics and applicable material/process/functional requirements for a new item, supplier, or facility—or after long production gaps (often ≥2 years).
In context, it establishes the production baseline for your process, becomes the reference for future Partial/Delta FAIs, and is frequently mandated in aerospace industry standards and purchase orders. It validates readiness before run-at-rate, PPAP elements, or broader capability studies, and it anchors your inspection plan and downstream quality control. The Full FAI FAIR captures part number accountability, materials and special processes, and characteristic accountability with GD&T results, gage IDs, and calibration dates mapped to the balloon drawing.
Partial first article inspection
A Partial FAI is a scoped verification that targets only the affected characteristics or processes—such as a coating specification update, fixture change, or minor design revision—while checking that interfacing features still meet design specifications. In context, it is the practical tool to confirm conformity after controlled design changes without re-measuring every unchanged feature. The report must clearly cross-reference the original Full FAIR, enumerate differences by revision delta and balloon IDs, and include any supporting certs or process inspection evidence tied to the change record.
Delta first article inspection
A Delta FAI is a Partial FAI explicitly tied to a change notice or ECN. Its purpose is to show conformity of all changed features and continued conformity of any dependent or linked characteristics. Fit/context: the FAIR should include a delta table comparing original vs current requirements, list updated specs/tolerances, and highlight changed balloons. The inspector records measurement results, gage/method, and pass/fail for each changed characteristic, maintaining traceability to the prior FAIR and the engineering drawing revision.
Piece-part/component FAI
A component FAI verifies a single detailed part—the building block for assemblies. The FAIR includes raw material properties records (mill CoCs, heat/lot), full dimensional record with gage traceability, and special process certificates (e.g., plating, anodize) as required by the product specifications. This level anchors part design requirements and sets clean interfaces for later assembly FAI linkages, reducing ambiguity when you scale to production batches or multi-supplier programs.
Assembly FAI
An Assembly FAI verifies a built item with a BOM and interfaces. AS9102 Form 1 (Part Number Accountability) lists subcomponents, any serials, and links each to its subcomponent FAIR number, ensuring vertical accountability and compatibility across the build. Measurement and functional checks address assembly-level features, markings, and specified tests. This linkage preserves the digital thread through components, work orders, and sub-assemblies, enabling efficient audits and change impact analysis.
Interim first article inspection
An Interim FAI is a time-boxed verification used between milestones—after tool refurbishment, process relocation, or prior to full FAIR—to de-risk ramp-up. It concentrates on high-risk CTQs, confirming that targeted characteristics and special processes are stable while you prepare the broader process report and evidence package for the next Full or Partial FAIR.
What is measured in a first article inspection?
All toleranced characteristics and specified attributes of the part or assembly are measured or verified against design requirements. This includes variable dimensions—linear sizes, diameters, profiles, and positions with GD&T per ANSI Y14.5—as well as drawing notes, surface finish, material properties (hardness, tensile), markings/labeling, special processes, and any functional tests required by the engineering drawing or contract. Each line item records the measurement method, Gage ID, calibration status and due date, and confirms resolution at roughly one-tenth of the tolerance. For grouped features (e.g., profile or position arrays), you may report min/max statistics if within tolerance; otherwise, list non-conformances individually with NCR references. Typical metrology includes fixed or portable CMMs, optical scanners, and calibrated hand tools (calipers, micrometers), with portable options for large components. Where available, DPD/CAD provides the nominal reference so measurements can align cleanly to model-based features in your inspection plan.
What is not measured in a first article inspection?
Basic dimensions (boxed) are not measured; they are theoretically exact and feed GD&T controls, so they carry no direct tolerance. FAI also does not quantify process capability—no Cp/Cpk or run-at-rate—unless a program specifically requires it. Avoid inventing ad-hoc tolerances for basics; instead, evaluate the controlled GD&T features (e.g., position, profile). Approval “golden” samples are not substitutes for FAI because they may not be production-representative; aesthetic checks are included only when the customer requirements specify them. Treat FAI as a conformity snapshot and process validation step within the quality management system, not a guarantee of defect-free mass production. Misreading its purpose can create risk by masking measurement system gaps or process flow instabilities that only appear under sustained load.
How many pieces are required for a first article inspection?
Programs commonly inspect 1–5 pieces; 3–5 is typical for confidence, and 1 may be used when parts are rare or costly. All samples must be production-representative and randomly selected from the first run. Some customers or industries define specific sample counts or timing—for example, initiating checks when roughly 1–10% of an order has been produced in certain aerospace workflows—to reduce the chance of scaling defects. Customers may independently verify a subset to align measurement methods; any discrepancies prompt method alignment, tooling or process adjustments, or drawing clarification. The key is balancing cost, schedule, and assurance: enough parts to confirm repeatability without delaying the production run or exhausting limited material, while preserving the integrity of your FAIR and the path to approval.
How should you prepare for a first article inspection?
Preparation consolidates requirements, plans the inspection, confirms metrology capability, and readies production-representative samples; 8 steps are included.
1) Define scope and triggers
Identify Full vs Partial/Delta based on change impact to fit-form-function, materials, or processes.
2) Assemble the technical data package
Collect drawings/CAD (DPD), BOM, specs, PO clauses, prior FAIRs, and customer templates.
3) Balloon the drawing and pre-build the characteristics table
Create unique balloon IDs for every requirement and map them to spec/tolerance/units.
4) Plan acceptance and sampling
Set attribute vs variable checks, sample size, timing (first batch), and inspection plan routing.
5) Verify gage calibration and environment
Confirm calibration due dates, gage resolution (~1/10 tolerance), and environmental controls.
6) Run the first production using final conditions
Use final materials, tooling, and routings; tag FAI parts and segregate them.
7) Stage FAIR templates and approvals
Prepare AS9102 Forms 1–3, sign-off routing, and schedule any source inspector.
8) Coordinate stakeholders
Align buyer, engineers, and QA on non-conformance handling and data-retention expectations.
What is material verification in FAI and why does it matter?
Material verification confirms that raw materials conform to the specified grade/standard via certificates of conformance (CoC) and, where required, chemical and mechanical tests, maintaining heat/lot traceability. Typical CoC fields include mill name, material grade, reference standard (e.g., ASTM), form/dimensions, heat lot number, quantity covered, actual chemistry, mechanical results (yield, tensile, hardness), and country of origin. Each record must tie to the specific lot used in the FAI part and to the work order on AS9102 Form 2. Applications span metals (hardness/tensile), plastics (resin specs and certifications), electronics (RoHS/lead-free declarations), and special processes (e.g., plating hardness/adhesion). Robust material verification prevents substitutions, supports compliance during audits, and secures the digital thread from raw stock to final product quality.
What happens during a first article inspection?
An authorized inspector measures and verifies all specified characteristics on a production-representative sample using calibrated metrology, records results against tolerances, and issues a FAIR for review and approval. The inspector follows a checklist derived from the ballooned drawing, then uses CMMs (fixed/portable), 3D scanners, micrometers, calipers, multimeters, or scrape testers as applicable. Each line captures requirement, actual value, method, Gage ID, calibration due date, and pass/fail. Any non-conformances are documented with disposition and proposed corrective actions. Production stays paused until disposition is complete; passing results permit continuation to the next quality step, while failing results trigger containment, root-cause analysis, corrective action, and a re-FAI (full or delta as appropriate). The approved FAIR becomes your baseline for subsequent lots and process monitoring.
What are the stages of a first article inspection?
FAI flows from need identification through approval and release:
- Define FAI need (full vs partial).
- Conduct first production run under final conditions.

When might a first article inspection be unnecessary?
FAI may be unnecessary for low-risk, low-cost consumer goods or mature parts produced by a proven supplier with stable production processes and robust quality control, where DUPRO and final inspections are sufficient. In some contexts, clients choose a pilot run—tens to hundreds of units—to demonstrate capability in place of an FAI, but regulated sectors (notably aerospace/defense) typically require FAI by contract. If you pursue a waiver, make it explicit, document the risk mitigation plan, and confirm alternate verification such as enhanced in-process checks or short-interval audits. Remember: skipping FAI increases exposure to scale-up defects that can ripple through the supply chain, inflate costs, and endanger delivery schedules.
What should an FAI inspection plan include?
The plan must trace every requirement to a verifiable check with method, gage, tolerance, and acceptance criteria. Start with a ballooned drawing assigning unique IDs to all dimensions, notes, and GD&T callouts. Build a characteristics table mapping balloon ID → specification, tolerance, and units; define the measurement method, Gage ID, and calibration due date for each line. Specify sampling and timing (first batch of the first run), attribute vs variable checks, special processes, and any functional tests. Include the nonconformance disposition flow, signature blocks, and clear data-retention identifiers so auditors can confirm completeness years later. A strong plan reduces ambiguity, shortens review time, and smooths source approval.
What are the outputs and documentation from an FAI?
Outputs center on the FAIR package plus supporting artifacts. You’ll compile AS9102 Forms 1–3 with signatures and dates; ballooned drawings; dimensional records with Gage IDs and calibration due dates; raw material records (CoCs/heat lots); special process certificates; and any functional test procedures/results. Where applicable, include DPD/semantic GD&T evidence and calibration certificates for critical gages. Some customers also require a measurement-system traceability matrix and specified data-retention periods (multi-year—often decades in aerospace). For assemblies, stress cross-linking: assembly FAIRs must reference each component FAIR, part number, and serial to maintain vertical traceability. This documentation underpins audits, streamlines change control, and protects schedules during source buy-off.
What is a First Article Inspection Report (FAIR)?
A FAIR is the documented evidence that the first article conforms to customer requirements and design specifications. In aerospace/defense, it follows AS9102 and comprises three forms: Part Number Accountability (Form 1), Product Accountability for materials, special processes, and functional tests (Form 2), and Characteristic Accountability showing measurements versus requirements (Form 3), each linked to the ballooned drawing. The FAIR is the artifact used for acceptance, audits, and long-term traceability across the supply chain and manufacturing process.
What is included in the Raw Material Record?
This section proves conformance and traceability of raw materials used in the FAI part. Capture mill name, material grade, reference standard number, form/dimensions, heat/lot, quantity covered, actual chemistry, mechanical test results, and country of origin. Tie the record to the specific work order/serial used during the FAI, and include any special-process certs (e.g., plating, heat treat) when material properties are altered. These fields support product accountability, auditability, and quick containment if a deviation is found in later lots.
What is included in the Dimensional Record?
This is the line-by-line tabulation of attribute and variable characteristics with the requirement, actual result, and pass/fail. Record the method and Gage ID (with calibration due date), and confirm gage resolution is adequate for the tolerance. For grouped features (profiles/positions), note any min/max reporting rules and list non-conformances with NCR IDs. The record must map cleanly to balloon IDs and drawing zones, preserving compatibility with CMM or scanner datasets and supporting measurement results imports from metrology software.
What are AS9102 standard forms?
AS9102 prescribes three standardized forms to capture part accountability, material/process/test accountability, and characteristic accountability. The forms distinguish required, conditionally required, and optional fields to ensure completeness and comparability across the aerospace supply chain. Consistent use improves review efficiency, reduces transcription errors, and strengthens compliance with aerospace industry standards.
What is AS9102 Form 1 (Part Number Accountability)?
Form 1 is the top-level ledger for the FAI item. It links part numbers, revisions/ECNs, work orders/jobs, configuration baselines, and—if an assembly—each subcomponent part number and any serial numbers. It also lists the FAIR number for each subcomponent, ensuring vertical traceability from components through the assembly.
What is AS9102 Form 2 (Product Accountability: Materials, Special Processes, and Functional Testing)?
Form 2 records all raw materials and special processes, including specification numbers, supplier approvals or codes, and any functional testing performed with procedure identifiers and results. When customers require approved special-process suppliers, Form 2 demonstrates that compliance and approvals are in place before release.
What is AS9102 Form 3 (Characteristic Accountability, Verification, and Compatibility Evaluation)?
Form 3 lists every design characteristic (balloon ID with sheet/zone), the requirement (nominal/tolerance), the measurement result, method, Gage ID, and Pass/Fail. It anchors verification to the ballooned drawing and, when applicable, to DPD/semantic GD&T features consumed by metrology software. All non-conforming characteristics reference NCRs for transparent disposition.
What is a ballooned drawing in FAI?
A ballooned drawing (or CAD view) assigns a unique ID to each design characteristic so requirements map one-to-one to Form 3 line items. Modern tools can automate ballooning via CAD/DPD or OCR, extracting dimensions, notes, and GD&T callouts into a characteristics table. Complete balloon coverage prevents missed requirements and simplifies source inspector review.
What change documentation is required for FAI?
Include ECNs, revision histories, route changes, supplier/location moves, and any waivers/deviations. For Partial/Delta FAIs, add a delta table mapping changed balloon IDs and specs versus the original FAIR, with clear references to superseded requirements.
What approval and release documentation result from FAI?
Close with internal QA sign-off, customer approval, and—if applicable—source inspector buy-off. Issue release notices to production, update control plans if needed, and archive the full FAIR package per contract (e.g., long-term retention in aerospace). These records support future audits and rapid problem resolution.
How do you create a first article inspection report (FAIR)?
Overview: FAIR creation compiles accountability, measurements, and evidence in the AS9102 structure; 7 steps are included.
- Prepare Forms 1–3 shells and filenames.
- Enter part number accountability and configuration data.
- Attach material, special-process, and functional-test records.
- Import dimensional data (CMM/hand tools) and map to balloon IDs.
- Flag non-conformances and capture corrective actions.
- Collect signatures/approvals, including any source inspector.
- Export/retain per contract (PDF plus native data, searchable by part/customer/gage ID).
Who is responsible for performing a first article inspection?
The supplier/manufacturer is typically responsible for conducting FAI. Execution may be performed by in-house QA, an authorized second party, or an independent third party with appropriate metrology and CMMs. Customers and source inspectors may witness or approve the FAIR; in aerospace programs, AS9102-compliant FAIRs are often required, with flow-down to sub-tier processors for special processes. Clear roles, documented procedures, and access to calibrated equipment keep quality assurance tight and customer expectations aligned.
Which industries use first article inspection and for what applications?
FAI is prevalent where precision, safety, and traceability are paramount. There are 7 applications:
- Aerospace & defense — AS9102 compliance for safety-critical flight hardware.
- Automotive — Embedded within APQP/PPAP for high-volume tooling and design changes.
- Medical devices — ISO 13485 documentation for device files and verification of biocompatibility-relevant features.
- Electronics/Electrical — Connector interfaces, dielectric and functional tests.
- Precision machining — Tight-tolerance components with advanced GD&T controls.
- Plastics/Injection molding — Tooling validation, resin changes, and process stabilization.
- Energy/Industrial equipment — Rotating components and pressure parts requiring materials testing and traceability.
How is FAI applied in aerospace?
Aerospace programs usually mandate AS9102 FAIRs (Forms 1–3), supplier flow-down to sub-tiers, and frequent source inspector buy-off. Expect long data-retention periods and strict model-based controls under ASME Y14.41 and OEM DPD rules. Structured FAIRs, complete balloons, and calibrated gage records speed approvals and reduce risk during critical hardware releases.
How is FAI applied in automotive?
In automotive, FAI activity lives inside APQP/PPAP. Dimensional results and gage studies support a broader PPAP evidence set—control plans, PFMEA, process flows, and capability at quoted rate. While FAI confirms conformance of initial pieces, PPAP demonstrates sustained capability across production batches.
How is FAI applied in medical devices?
Under ISO 13485, FAI supports design control and the device master record by verifying materials, biocompatibility-relevant features, and functional tests defined in the product design and risk files. Documentation discipline and traceability protect patients and facilitate regulatory inspections.
How does first article inspection compare with PPAP?
FAI is a subset of PPAP focused on part conformance and accountability for a small sample (often one part), while PPAP is a broader production part approval process that proves the production system at rate with multiple parts and extensive documentation. FAI concentrates on measurements against design and customer specifications; PPAP adds control plans, PFMEA, process flows, gage R&R, and capability studies. Typical sample sizes differ (FAI 1–5 vs PPAP tens–hundreds). Objectives differ as well: FAI validates readiness, PPAP demonstrates sustained capability at the quoted volume. Deliverables differ: FAIR vs a PPAP packet with the recognized elements (up to 18). Both reduce risk and protect the supply chain, but PPAP is the wider umbrella.
| Factor | FAI | PPAP |
| Primary goal | Conformity of first article | Production-process approval at rate |
| Sample size | 1–5 pieces | Tens–hundreds |
| Scope | Dimensional/material/functional vs design | Above + control plans, PFMEA, process flows, gage R&R, capability |
| Core output | FAIR (AS9102 Forms 1–3 + evidence) | PPAP packet (up to 18 elements) |
| Typical use | Aerospace, medical, precision machining | Automotive; increasingly adapted in aerospace via 9145 |
What is the difference between FAI and FAIR?
FAI is the inspection process/event that verifies a production-representative unit against design and contract requirements; FAIR is the document set (AS9102 Forms 1–3 with attachments) that records the objective evidence. The FAIR is used for acceptance, audits, and traceability, while the FAI itself is the hands-on measurement and verification step within your quality control system.
What software and technology support first article inspection?
Tools fall into four groups: CAD-integrated ballooning (automatic ID/OCR), FAIR generators/templates, CMM/optical scanner software that imports results to Form 3, and certificate/document management that links subcomponent FAIRs and enforces long-term retention. Selection criteria include speed of ballooning, quality plan generation, CMM/optical data import, CoC storage, subcomponent FAIR linking, searchability by part/customer/Gage ID, and retention periods (multi-decade for aerospace). Automation reduces transcription errors, preserves the digital thread and semantic GD&T, and accelerates source buy-off—especially when paired with portable metrology for large goods.
What is a ballooning tool and how does it integrate with CAD?
Ballooning tools overlay unique IDs on drawings or 3D models and map each design characteristic to a characteristics table. Strong integration supports DPD and semantic GD&T, allowing metrology software to consume features directly and maintain associativity through the FAIR workflow. This alignment improves inspection plan creation, process flow, and audit clarity.
How do CAD-integrated inspection tools streamline FAIR creation?
They eliminate manual transcription, import measured data straight into Form 3, and maintain traceability from model feature → balloon ID → measurement result. OCR or model-based extraction speeds setup, reduces data-entry errors, and ensures compatibility across CMMs, scanners, and hand-tool records.
How is automation used for ballooned drawing reporting?
Automation parses drawings/models to auto-number characteristics, build the characteristics table, and pre-populate required or conditionally required fields. CMM programs—fixed or portable—can be auto-generated to measure those features and feed results back into the FAIR, tightening quality assurance and shortening review cycles.
What is the short history of first article inspection?
FAI traces to mid-20th-century aerospace/defense procurement, where verification before mass production was essential for safety and mission success. As formal quality systems matured—MIL/Q frameworks and the ISO 9000 family—procurements increasingly required documented conformance of an initial article before scale. The International Aerospace Quality Group (IAQG) harmonized expectations, and SAE AS9102 codified aerospace FAI requirements and FAIR forms, with modern revisions maintained by IAQG/SAE. Meanwhile, the automotive industry developed a parallel but broader framework (APQP/PPAP) to approve high-volume production processes. In 2016, AS/EN/JISQ 9145 introduced APQP/PPAP concepts into aerospace, aligning terminology and expectations. The DPD era accelerated change: ASME Y14.41 and OEM specifications (e.g., Boeing model-based rules) drove model-based definition and traceability that now permeate ballooning tools, CMM workflows, and long-term documentation practices across complex supply chains.
What are the common limitations and challenges of first article inspection?
FAI can be time-consuming, is sometimes misread as proof of capability, and may expose measurement-system weaknesses. There are 10 disadvantages:
- Do not assume zero defects post-FAI—process drift can occur.
- Do not equate FAI with capability; Cp/Cpk and run-at-rate are not proven.
- Do not overlook measurement uncertainty; edge-of-tolerance results can mislead.
- Do not ignore gage suitability (resolution, calibration, traceability gaps).
- Do not under-resource documentation—manual FAIRs are error-prone.
- Do not allow scope creep (e.g., measuring basic dimensions).
- Do not delay alignment on methods; buyer/supplier disagreement wastes time.
- Do not expect stable processes from a single first-run setup.
- Do not underestimate cost/schedule impact (metrology time, source buy-off).
- Do not weaken assembly-to-component linkage; missing cross-references hurt audits.
What legal and regulatory requirements apply to FAI, and how do standards vary globally?
Contractual and industry standards define FAI form and rigor: AS9102 in aerospace/defense; APQP/PPAP in automotive; ISO 13485 expectations for medical devices; and ISO 9001 linkages for QMS integration. AS9102 prescribes three FAIR forms and supplier flow-down; automotive adds broader evidence—control plans, PFMEA, and capability—around the initial article. Medical devices require alignment with the device file and documented verification of materials and functional characteristics. Local OEM specs (notably DPD controls) and regulatory rules add further requirements, especially for export controls and data-retention windows.
How do FAI standards differ across global markets?
Definitive: aerospace supply chains converge on AS9102 FAIRs, automotive on APQP/PPAP, and medical on ISO 13485, each with unique document sets and approval expectations. Some regions or OEMs require source inspector buy-off and explicit approvals for special processes. Model-based definition and DPD rules are increasingly universal, improving traceability and reducing ambiguity across borders.
How much does the first article inspection cost?
Indicative ranges vary by region and complexity. Many suppliers charge USD $75–$300+ per FAIR for paperwork only, while independent on-site FAIs are often billed per man-day (around USD ~$299/day in major Asia hubs, plus travel). In the U.S., inspection personnel compensation (often ~$25–$27/hour) influences shop rates for metrology time. There are 10 cost factors:
- Part complexity/feature count.
- Required sample size (1 vs 3–5).
- Metrology method (hand tools vs CMM/optical scan) and programming time.
- FAIR format (AS9102 vs custom) and data entry effort.
- Special processes and functional tests.
- On-site vs off-site, travel, and logistics.
- Urgency/expedites and re-FAIs after fails.
- Supplier documentation maturity (CoCs, DPD controls).
- Source inspector presence and buy-off time.
- Data retention/archival and language/translation needs.
How do you select a first article inspection service provider?
Overview: selection balances competence, accreditation, tooling, and responsiveness; 7 steps are included.
- Verify certifications/accreditations (AS9100/ISO 9001; ISO 13485 where relevant; AS9102 FAIR competency).
- Assess case studies and sector experience with similar tolerances/materials.
- Confirm metrology capability (CMM volume, scanners, DPD handling, electrical tests).
- Check data security/retention and searchability (by part/customer/gage ID).
- Benchmark pricing/TOC across multiple quotes.
- Check references and sample FAIRs.
- Review contract terms (scope, re-FAI triggers, IP/confidentiality).
How do you verify certifications and accreditations?
Definitive: require current certificates and scope statements, then verify them on issuer databases. Confirm staff competency with AS9102 FAIRs and any regulatory-specific needs (e.g., medical). Check calibration accreditation of in-house labs or third-party certs and the ability to manage DPD/export-controlled data when applicable.
How do you evaluate track record and reputation?
Definitive: demand references and examples of resolved non-conformances and successful source buy-offs. Review sample FAIRs for completeness and clarity, and look for strong on-time performance on prior FAIs with similar processes and materials.
How do you assess technical capability and scope?
Definitive: match metrology/tooling and software to your features—CMM volume, probing vs scanning, GD&T complexity, and electrical/functional tests. Confirm they can import your CAD/DPD and export FAIRs into your templates without losing balloon mapping.
How do you benchmark pricing and total cost of ownership?
Definitive: compare man-day rates, per-FAIR fees, travel, and re-FAI costs across 3–5 quotes; consider schedule risk, source buy-off support, and data retention. Avoid low “paper-only” offers that skip real metrology.
How do you use referrals and references effectively?
Definitive: prioritize referrals from programs with similar tolerances, materials, and standards. Ask referees about responsiveness during NCRs, thoroughness of corrective actions, and clarity of documentation.
What contract terms and liabilities should you review?
Definitive: specify scope (full vs partial), deliverables (AS9102 forms, digital datasets), acceptance criteria, confidentiality/IP of CAD/DPD, liability for missed defects, re-FAI triggers, and data retention; include an escalation path for disputes.
How do you ensure quality in FAI service delivery?
Definitive: require a documented FAI procedure, internal audits, and example FAIRs. Confirm calibration controls and competency records, and mandate timely NCR communication with tracked corrective actions and closure evidence.
How do you gain source inspector buy-off?
Overview: preparation, professionalism, and automation smooth approvals; 7 steps are included.
- Pre-agree scope, templates, and acceptance criteria.
- Provide a clean, complete FAIR package.
- Stage calibrated gages and show traceability.
- Demonstrate DPD/balloon mapping and measurement results integrity.
- Be ready with containment and corrective action plans.
- Run an efficient, respectful review flow on site.
- Document buy-off and capture lessons learned for next time.
How do you train your team for effective first article inspections?
Overview: training covers standards, metrology, and documentation; 6 steps are included.
- Standards familiarization (AS9102/PPAP).
- GD&T proficiency for inspectors and engineers.
- Gage handling and calibration awareness.
- CAD/DPD and ballooning tools practice.
- FAIR data entry, review, and sign-off routines.
- Mock FAIs with feedback loops and scenario-based drills.
What challenges arise when adapting FAI to small-scale or low-volume production?
Definitive: cost/time overhead and metrology access are proportionally high. Mitigate by scoping partial FAIs to real risk, using shared or portable CMMs, and right-sizing documentation while preserving traceability and accountability. Align with the buyer on evidence expectations so you maintain quality without stalling a short production batch.
What future trends will impact first article inspection?
Definitive: model-based definition with semantic GD&T, integrated digital threads, automated ballooning/OCR, and portable/non-contact metrology will speed FAIs and strengthen traceability. Expect broader adoption of aerospace APQP/PPAP practices, bringing consistent process flow and risk tools to complex hardware. Long-term, secure data retention and analytics—linking measurement results across lots and suppliers—will guide quality control strategies and risk mitigation earlier in the lifecycle.
What happens if a component passes or fails the first article inspection?
Definitive: Pass → production resumes and the FAIR becomes the baseline; Fail → production stops, root cause/corrective action occurs, and a new FAI (full or delta) confirms resolution. Common fail modes include wrong or low-quality material, mis-set processing equipment, and dimensional or surface finish nonconformities. Transparent communication with your customer, documented CAPA, and clean resubmission protect relationships and prevent recurrence—keeping your manufacturing process on schedule and your product quality predictable.
Conclusion
FAI is an early, documented gate that protects schedule and cost by proving conformance and validating your manufacturing process before scale. When you pair CAD-integrated ballooning, disciplined gage controls, and complete FAIR packages with clear buyer–supplier collaboration, you shorten approval time, reduce defects, and preserve the digital thread for future audits and changes. Use FAI as your first, focused checkpoint—then flow those lessons into control plans, SPC, and continuous improvement across the entire production run.
