First Article Inspection (FAI): Ensuring Quality in Manufacturing

In today’s fast-paced manufacturing world, First Article Inspection (FAI) is a crucial quality control process that ensures production consistency and compliance with industry standards. By verifying that every part in a batch meets design specifications, FAI helps minimize defects, reduce costs, and maintain reliability across aerospace, automotive, medical, electronics, and other high-precision industries. This article provides a comprehensive guide on the importance, process, benefits, challenges, and future trends of FAI.

What is First Article Inspection (FAI)?

First Article Inspection (FAI) is a quality assurance process where a sample product from an initial production run is thoroughly inspected against its design specifications, engineering drawings, and industry standards.

Objectives of FAI

• Verify that the manufacturing process can consistently produce parts according to design specifications.
• Identify any process inefficiencies or defects before full-scale production.
• Ensure compliance with customer requirements and industry regulations.
• Reduce the risk of costly rework, recalls, or non-conformance issues.

FAI acts as an early warning system, catching errors before they become expensive problems.

Evolution of First Article Inspection

Historical Background

The origins of FAI date back to World War II, when the need for precision in aerospace and defense manufacturing led to the development of strict inspection protocols. Early FAI was a manual process, relying heavily on visual inspections, calipers, and paper-based records.

The Impact of Technology

Over time, digital advancements have transformed FAI:

• 1980s-1990s: Introduction of Coordinate Measuring Machines (CMMs) for automated inspections.
• 2000s: Adoption of Computer-Aided Design (CAD) and Computer-Aided Manufacturing (CAM).
• Present Day: Integration of Artificial Intelligence (AI), 3D scanning, and IoT-based smart inspection systems for faster and more accurate

Why is First Article Inspection Crucial?

Ensuring Compliance

FAI ensures that every manufactured part complies with:

• Customer specifications
• Engineering drawings
• Regulatory standards(AS9102 for aerospace, ISO 13485 for medical devices, PPAP for automotive)

Preventing Defects and Quality Issues

By catching defects early, FAI helps:

• Avoid costly rework
• Prevent production downtime
• Improve efficiency and reduce waste

Enhancing Customer Satisfaction

Companies using FAI experience fewer product recalls and higher customer confidence, leading to long-term business relationships.

When is a First Article Inspection Required?

FAI is necessary under several conditions:

Scenario	Reason for FAI
New product introduction	Ensures the product meets specifications before mass production.
Design changes	Verifies that modifications have not affected quality.
New supplier or production facility	Ensures consistency across different locations.
Production pause (over 2 years)	Ensures process stability before restarting production.
Industry regulations	Aerospace, medical, and automotive industries require FAI for compliance.

First Article Inspection Process

Gather the Necessary Documents

Before starting the inspection, it’s important to have all the required paperwork ready, including:

• Engineering Drawings– Detailed blueprints of the part, including dimensions and tolerances.
• Material Certifications– Proof that the raw materials meet the required specifications.
• Process Documentation– A record of how the part is made, including machining, welding, coating, or any other process.
• Inspection Plan– A checklist of what needs to be measured and tested.

💡 Tip: Keeping everything organized makes the inspection process faster and smoother.

Select the Sample Part

The first part (or sometimes a few parts) from the production batch is chosen for inspection. This part should be made using the same equipment, tools, materials, and processes planned for full production.

Why? Because if there’s an issue, fixing it now is much easier than dealing with hundreds of defective parts later.

Perform the Inspection

This is where the real testing happens. Inspectors check the physical, dimensional, and functional aspects of the part to ensure it matches the design.

• Dimensional Inspection– Using tools like calipers, micrometers, and Coordinate Measuring Machines (CMMs) to measure size, shape, and tolerances.
• Material & Component Check– Verifying that the correct materials were used and that they meet industry standards.
• Surface & Finish Inspection– Checking for smoothness, coatings, and any cosmetic defects.
• Functional Testing– Ensuring the part works as intended, especially in industries like aerospace and medical devices.

💡 Tip: Advanced tools like 3D scanners and optical comparators can speed up the inspection process and improve accuracy.

Document the Findings

All inspection results are recorded in a First Article Inspection Report (FAIR), which includes:

• The part’s measured values compared to the design specs.
• Any deviations or defects
• The inspection methods and tools
• Approval or rejection based on compliance with standards.

This documentation is critical because it serves as proof that the product meets requirements and can be used for future reference.

Address Any Issues

If the part passes inspection, production can continue with confidence.

If the part fails, the manufacturer must:

• Identify the root cause of the problem (wrong material, incorrect machining, etc.).
• Make corrections to the process or design.
• Conduct a new inspection to confirm that the issue is resolved.

💡 Tip: Fixing a problem before mass production saves time and money while ensuring better product quality.

Final Approval & Production Release

Once everything checks out, the FAI is approved by the quality control team or customer, and full-scale production can begin.

This final approval means that the manufacturing process is reliable and will continue to produce high-quality parts that meet the required standards.

Why This Process Matters?

• Reduces manufacturing defects by catching issues early.
• Saves money by preventing costly rework or recalls.
• Ensures compliance with industry standards (AS9102 for aerospace, ISO 13485 for medical, etc.).
• Builds customer trust by proving quality from the start.

By following these steps, manufacturers can avoid major production headaches and ensure that every part meets expectations before large-scale manufacturing begins.

Who Performs First Article Inspections?

First Article Inspections (FAI) aren’t just done by one person—they require a team effort involving different experts who specialize in quality, engineering, and manufacturing. Depending on the industry and the complexity of the part, multiple people may be involved to ensure every detail is checked before full production begins.

Let’s take a look at the key players in an FAI process:

Quality Control (QC) Inspectors – The Detail-Oriented Experts

These are the people who perform the actual inspection, using specialized tools to measure and test the part. They check dimensions, materials, finishes, and functional aspects, making sure everything matches the design specifications.

💡 Think of them as the “final gatekeepers” before a part goes into full production.

✔ What they do:

• Measure the part’s dimensions with calipers, micrometers, and CMM machines.
• Check for cosmetic defects, surface finishes, and coatings.
• Ensure the material used is correct (based on certifications and tests).
• Record all findings in the First Article Inspection Report (FAIR).

✔ Where they work:

• In manufacturing companies(automotive, aerospace, medical devices, etc.).
• At third-party inspection companies hired by manufacturers or customers.

Quality Assurance (QA) Engineers – The Compliance Experts

While QC inspectors focus on measuring parts, QA engineers take a big-picture approach. They ensure that the entire inspection process follows industry standards and that the right documentation is in place.

💡 They make sure everything is done “by the book” and meets industry regulations.

✔ What they do:

• Review FAI reports to ensure accuracy and completeness.
• Ensure compliance with standards like AS9102 (aerospace), ISO 13485 (medical), and PPAP (automotive).
• Work with production teams to correct any issues found during inspection.
• Approve or reject the FAI based on the results.

✔ Where they work:

• In manufacturing facilities that produce high-precision parts.
• At supplier quality control teams in aerospace, defense, and medical industries.

Manufacturing Engineers – The Problem-Solvers

Manufacturing engineers are responsible for how a part is made. If an FAI fails, they are the ones who analyze and fix the production process to ensure that future batches meet specifications.

💡 They are like “troubleshooters” who solve problems in the production line.

✔ What they do:

• Analyze manufacturing methods to find potential errors or inefficiencies.
• Work with machinists and production teams to adjust equipment, tools, or materials.
• Implement process improvements to prevent defects in future production runs.
• Provide technical guidance to quality teams on design and machining processes.

✔ Where they work:

• In CNC machining shops, injection molding facilities, and die-casting factories.
• At aerospace, automotive, and electronics manufacturers.

Supplier Quality Engineers (SQEs) – The Supplier Checkers

If a company outsources parts to another manufacturer, Supplier Quality Engineers step in to ensure those parts meet required quality standards before they arrive at the production facility.

💡 They work between the manufacturer and supplier to avoid production delays and defects.

✔ What they do:

• Inspect suppliers’ FAI reports to ensure the parts meet design requirements.
• Conduct on-site supplier audits to review their quality control processes.
• Approve or reject shipments based on FAI results.
• Work with suppliers to fix issues before production scales up.

✔ Where they work:

• In companies that rely on external suppliers for critical parts.
• At automotive, aerospace, and medical device manufacturers.

Third-Party Inspection Services – The Independent Verifiers

Sometimes, companies hire outside experts to perform FAIs, especially when dealing with high-value or high-risk parts. These independent inspectors provide an unbiased review of the part’s quality.

💡 Think of them as “quality consultants” who ensure fairness and compliance.

✔ What they do:

• Perform FAI inspections for clients who don’t have in-house quality teams.
• Use advanced inspection tools like 3D scanners, CMMs, and X-ray machines.
• Provide detailed inspection reports and recommendations.
• Help manufacturers meet industry standards and avoid compliance issues.

✔ Where they work:

• At specialized testing and certification companies.
• In industries where third-party verification is required, like aerospace, defense, and medical devices.

Types of First Article Inspections

First Article Inspection (FAI) isn’t a one-size-fits-all process. Depending on the product, industry, and production changes, different types of FAIs are used to ensure quality and accuracy before full production begins. Some FAIs are full-scale inspections, while others focus only on specific parts or modifications.

Let’s break down the different types of FAIs and when they are needed.

Full First Article Inspection – The “Complete Check”

A Full First Article Inspection is the most thorough and detailed type. It’s done when a brand-new part is being manufactured for the first time or when a product has gone through major design changes.

💡 Think of this as a “fresh start” inspection, where everything is checked from top to bottom.

✔ When is it needed?

• When a company starts making a new product.
• After big design changes(e.g., switching materials, redesigning critical features).
• When switching to a new factory or supplier.
• After a long production break(typically two years or more).

✔ What does it check?

• Every dimension, feature, and material.
• Manufacturing processes and equipment setup.
• Surface finish, coatings, and special treatments.
• Functional testing to ensure the part works as expected.

🛠 Example: An aerospace company making a new aircraft component would require a Full FAI to check every detail before approving mass production.

Partial First Article Inspection – The “Targeted Check”

A Partial FAI focuses only on specific changes made to a product or process, rather than inspecting everything from scratch. It’s used when minor design tweaks occur, but most of the part remains unchanged.

💡 Think of this as a “spot check” that saves time and effort while ensuring new changes are correct.

✔ When is it needed?

• When only a few dimensions or features have changed.
• If a new tool or machine is being used to make the part.
• When a supplier updates a manufacturing process.

✔ What does it check?

• Only the changed or affected areas.
• Any new materials or coatings.
• Updated process steps that could impact quality.

🛠 Example: If an automotive manufacturer changes the shape of a car door handle slightly, they would perform a Partial FAI to check just that feature instead of rechecking the entire door assembly.

Delta First Article Inspection – The “Change Confirmation”

A Delta FAI is similar to a Partial FAI but is more specific to engineering changes. If a part has already passed a Full FAI but later needs small updates, a Delta FAI ensures those updates don’t cause problems.

💡 Think of this as a “quick double-check” after small adjustments.

✔ When is it needed?

• After design tweaks that affect only a small part of the component.
• When engineering revisions change how the part is made.
• If new regulatory or customer requirements apply to the part.

✔ What does it check?

• Only the features impacted by the design change.
• The effect of changes on overall part functionality.
• Updated drawings and process documentation.

🛠 Example: A medical device company modifies the thickness of a plastic casing. A Delta FAI checks the new thickness but skips testing the electronic parts inside, since they haven’t changed.

Piece Part / Component FAI – The “Individual Part Check”

A Piece Part FAI focuses on one single component before it’s assembled into a larger product. This is essential when different suppliers provide different parts for an assembly, ensuring everything fits together perfectly.

💡 Think of this as inspecting “each puzzle piece” before putting the whole puzzle together.

✔ When is it needed?

• When a supplier delivers key components(e.g., fasteners, brackets, gears).
• Before assembling multiple parts into a final product.
• To ensure supplier compliance with specifications.

✔ What does it check?

• The dimensions, material, and finish of the individual part.
• Whether the part matches the CAD model or engineering drawings.
• If it will fit and function properly in the final assembly.

🛠 Example: A laptop manufacturer orders metal hinges from one supplier and plastic casings from another. A Piece Part FAI ensures each component meets the design specs before assembly.

Assembly FAI – The “Final Fit Check”

An Assembly FAI ensures that all individual components work together correctly in the final assembled product. Even if every part passes inspection on its own, they still need to be checked as a complete unit to avoid assembly issues.

💡 Think of this as a “test run” before the product hits full-scale production.

✔ When is it needed?

• After assembling multiple components into a finished product.
• To confirm proper fit, alignment, and function.
• When working with tight tolerances or moving parts.

✔ What does it check?

• Dimensional accuracy of the full assembly.
• Interaction between moving parts(e.g., hinges, gears, sliding mechanisms).
• Whether the product functions correctly when fully assembled.

🛠 Example: A company producing mechanical watches performs an Assembly FAI to ensure gears, springs, and hands fit and work together without friction or misalignment.

Interim First Article Inspection – The “Ongoing Check”

An Interim FAI is used when a company produces parts continuously over a long period and wants to check quality at regular intervals instead of just once at the start.

💡 Think of this as a “quality health check” to make sure everything stays on track over time.

✔ When is it needed?

• During long-term production runs(months or years).
• To catch any gradual shifts in quality before they become big problems.
• When a new batch of raw material is introduced into production.

✔ What does it check?

• Key dimensions and performance metrics at set time intervals.
• Consistency of materials and machining processes.
• Whether the production line is still meeting quality standards.

🛠 Example: A defense contractor making aircraft fasteners for 10 years may conduct an Interim FAI every 12 months to ensure that quality remains consistent.

FAI Tools & Methods

Tool/Method	Purpose
CMM (Coordinate Measuring Machine)	Measures 3D geometries with high precision.
3D Scanning	Captures complex shapes and fine details.
Optical Comparators	Magnifies part features for measurement.
Hardness Testers	Evaluates material durability.

First Article Inspection Report (FAIR)

FAIR is like a quality passport for a product. It documents all the important details from an initial production run, ensuring that a part meets all the required design, material, and performance specifications before full-scale production begins.

Let’s break down what a FAIR includes, why it’s important, and how it helps manufacturers avoid costly mistakes.

What’s in a First Article Inspection Report (FAIR)?

A FAIR is more than just a simple checklist. It’s a comprehensive document that provides a clear record of inspection results, showing that the first manufactured parts match the approved design.

A typical FAIR consists of three main sections, based on the AS9102 aerospace standard:

Part Number Accountability

🔹 What it covers:

• The part name and number(so you know exactly what’s being inspected).
• Drawing numbers and revisions(to ensure the latest design is used).
• The FAI report number(for easy tracking).
• Whether this is a full, partial, or re-inspection.

🔹 Why it matters:
This section makes sure everyone is on the same page about what part is being checked and that the correct design version is being used.

Product Accountability

🔹 What it covers:

• Materials and coatings
• Raw material certifications(proving that the material meets quality standards).
• Subassemblies or related components(if the part is part of a bigger system).
• Special processes(like heat treatment, anodizing, or welding).

🔹 Why it matters:
This section ensures that the right materials and treatments were used, preventing defects or failures due to incorrect material choices.

Characteristic Accountability & Inspection Results

🔹 What it covers:

• Every critical dimension(measured and compared to the design specs).
• Surface finishes and other key features.
• Inspection equipment used(calipers, micrometers, CMMs, etc.).
• Pass/fail results for each measurement.

🔹 Why it matters:
This section proves that the part meets all design tolerances and quality standards. If something doesn’t match up, it’s flagged so corrections can be made before mass production.

Why Is a FAIR Important?

A FAIR isn’t just paperwork—it’s a critical quality control tool that helps manufacturers avoid costly mistakes.

✅ Prevents production issues: Catching design or manufacturing problems early means fewer defects and less rework later.

✅ Ensures consistency: The report acts as a reference for all future production, ensuring that each batch matches the first approved part.

✅ Reduces risk: For industries like aerospace, medical, and automotive, where precision is everything, a FAIR ensures that every part meets strict safety and performance standards.

✅ Simplifies compliance: Many industries require a FAIR to prove compliance with ISO, AS9100, or other regulatory standards.

✅ Builds customer confidence: When clients see a detailed FAIR, they know they’re getting a high-quality, well-documented product.

How Is a FAIR Created?

Creating a FAIR requires careful inspection, documentation, and verification. Here’s a step-by-step look at the process:

1️⃣ Collect Engineering Drawings & Specs – Ensure you have the latest design revisions.
2️⃣ Identify Inspection Requirements – Decide what features and tolerances need checking.
3️⃣ Inspect the First Produced Part – Measure all critical dimensions, materials, and processes.
4️⃣ Document the Results – Record all measurements and material data in the FAIR.
5️⃣ Review & Approve – The quality team verifies the report before submitting it to the customer.

Is One Piece Enough for FAI?

In most cases, yes—only one piece is required for First Article Inspection. This single part is chosen from the first production run and is used to verify that the manufacturing process is capable of producing parts that meet design specifications and quality standards.

However, this one part isn’t just any random sample. It must be:
✅ Fully representative of the entire batch.
✅ Made using the actual production process (not a prototype or a test run).
✅ Checked against every critical dimension and requirement on the engineering drawing.

If that one inspected piece meets all requirements, then the rest of the batch is good to go for full-scale production.

When Are More Pieces Required?

While one part is the standard, there are situations where multiple pieces need to be inspected:

🔹 Customer or Industry Requirements
Some industries, like aerospace, medical, and defense, have stricter quality standards. For example:

• Aerospace (AS9102 standard)→ Typically one piece is inspected, but some customers may require more.
• Automotive (PPAP process)→ May require multiple samples to confirm process stability.
• Medical devices (ISO 13485)→ Can require extensive testing on several pieces.

If the client specifies that more than one part must be inspected, you must follow their requirements.

🔹 Complex Parts with Tight Tolerances
If a part has extremely precise measurements or complex features, inspecting just one piece might not be enough. In these cases, manufacturers may:

• Inspect a few extra pieces to confirm process stability.
• Use statistical sampling methods to check consistency.

🔹 New Manufacturing Process or Material
If a new material or process is being used for the first time, inspecting more than one part helps ensure consistency before mass production.

🔹 Production Issues or Past Failures
If a manufacturer has had problems with quality in the past, a customer may request FAI on multiple parts to verify improvements.

What Happens if a Product Fails FAI?

A failed FAI isn’t the end of the world, but it does mean there’s a problem that needs to be fixed before full production can move forward. Let’s break down what happens next in simple terms.

Step 1: Stop & Investigate the Issue

The moment a part fails FAI, the production process is paused to prevent more defective parts from being made. The quality team and engineers will work together to find out what went wrong.

Some common reasons for failure include:
❌ Incorrect dimensions – The part doesn’t match the blueprint.
❌ Material issues – The wrong material was used, or the material didn’t meet specifications.
❌ Manufacturing errors – A machine setting was incorrect, causing defects.
❌ Assembly mistakes – Parts weren’t put together correctly.

The goal here is to pinpoint the exact problem before moving forward.

Step 2: Root Cause Analysis (Finding the Problem)

Once the issue is identified, a Root Cause Analysis (RCA) is performed. This helps answer key questions:
🔍 Was the failure due to machine settings, human error, or faulty material?
🔍 Is it a one-time issue, or will it affect the entire production batch?
🔍 Has this problem happened before?

Some tools used to find the root cause include:
🛠 Fishbone diagrams – Helps identify multiple possible causes.
🛠 5 Whys analysis – Repeatedly asking “Why?” to trace the problem back to its source.
🛠 Failure mode and effects analysis (FMEA) – Assesses how the failure could impact the final product.

Step 3: Implement Corrective Actions (Fixing the Problem)

Once the root cause is identified, the next step is to fix the issue and prevent it from happening again. This may involve:

🔧 Adjusting machine settings – If the dimensions were off, recalibrating the machine can solve the issue.
🔧 Training operators – If human error was the cause, providing better training might be necessary.
🔧 Changing materials – If the wrong material was used, switching to the correct one ensures compliance.
🔧 Updating design specs – Sometimes, the design itself may need slight modifications to improve manufacturability.

Any corrections made are documented so that similar issues can be avoided in future production runs.

Step 4: Re-Inspection (Double-Checking the Fixes)

After the problem is fixed, the FAI process is repeated to confirm that the corrected part now meets all requirements. This means:

✅ Inspecting the part again using the same FAI process.
✅ Running additional tests if necessary.
✅ Ensuring that all corrections have successfully eliminated the defect.

If the part passes this time, production can continue as planned.

If the part fails again, the process loops back to Step 1, and a deeper investigation is conducted.

Step 5: Reporting & Documentation

Once the issue is resolved and the part passes inspection, the First Article Inspection Report (FAIR) is updated to document:
📄 The failure details.
📄 The root cause.
📄 The corrective actions taken.
📄 The results of the re-inspection.

This documentation helps keep track of quality improvements and serves as a reference for future production runs.

What Happens If the Problem Persists?

If a part continues to fail FAI even after multiple fixes, it could mean:
⚠ The design is flawed → The engineering team may need to revise the blueprint.
⚠ The manufacturing process is unsuitable → A different production method might be needed.
⚠ Supplier issues → If outsourced materials or components are failing, a new supplier may be required.

In such cases, discussions between engineers, quality teams, and customers are necessary to determine the best course of action.
