First Article Inspection Procedure 101: What, When & How

What is First Article Inspection?

First Article Inspection (FAI) is a quality assurance process that verifies whether the first production item – or a sample from the first batch – meets the required product design and customer specifications. It’s the check that happens before a factory scales from one sample to ten thousand units.

Skip it, and a design or process error that would have cost a few hundred dollars to fix in the first sample can turn into a mass-production disaster. If you’ve ever faced 10,000 parts that don’t fit the client’s design, you already know why FAI is non-negotiable.

The First Article Inspection Procedure: How the FAI Process Works in Real Life

The first article inspection process isn’t a random check – it’s a structured workflow designed to catch issues early. Here’s a step-by-step breakdown of how it plays out in a typical manufacturing scenario:

Imagine you’re a supplier producing plastic gears for an automotive client. After finalizing the design, you start the first production run. Before ramping up to 100,000 units, you need to run FAI:

• Select the Sample

Pick a random gear from the first 50 units (not the “very first” one – this ensures it’s representative of the batch).

• Assign Inspection Responsibility

You can do it in-house, but many clients prefer a third-party agent (like AQI Service) for impartiality.

• Run the Full Check

Compare the gear to the client’s design: measure tooth spacing, check plastic hardness, verify color matching, and test if it fits the client’s assembly.

• Document Results

Record every measurement and finding in an FAI report (FAIR) for the client to review.

Industry standards (like AS9100 for aerospace) often require this process to start when 1% to 10% of the order is produced. Why? Because if the first batch has a flaw – say, the gear’s hole is too small – fixing it now costs a few hundred dollars. Fixing it after 100,000 units? Tens of thousands, plus lost trust.

Tips from Experts: The FAI Process is only effective if you don’t cut corners. A common mistake is skipping small characteristics (like surface finish) because they seem “unimportant.” But for a medical device part, even a tiny scratch could lead to regulatory failures – so every detail counts.

Why is First Article Inspection Important?

FAI inspection is a cornerstone of quality control, and following the First Article Inspection Procedure offers both immediate and long-term benefits for production efficiency and product reliability:​

a. Early Issue Detection: Stop Defects Before They Scale

Identifies potential problems before mass production, avoiding costly defects.

A electronics manufacturer once skipped FAI for a new smartphone charger. They produced 50,000 units before realizing the charging port was misaligned – none of them worked with the client’s phones. Reworking all units cost $200,000, and the client delayed payment for 3 months. With FAI, they would have caught the misalignment in the first sample, fixing it for $500.

b. Regulatory Compliance: Avoid Costly Penalties

Minimizes waste and delays, crucial in high-precision industries like aerospace and medical devices.

In the aerospace industry, FAI isn’t optional – it’s required by AS9102. A supplier once failed to conduct FAI for a jet engine component and was fined $150,000 by the FAA. Worse, they lost their contract with a major airline. The first article inspection process ensures you have documentation to prove your parts meet the required standards, keeping regulators happy.

c. Build Trust with Clients

When you share a detailed FAI report with a client, you’re proving you take quality seriously. A furniture supplier we worked with used FAI reports to win a $1 million contract with a retail chain. The client was impressed that every table leg’s length was measured and recorded – showing consistency they couldn’t get from other suppliers.

Types of First Article Inspection: Choose the Right One for Your Project

Two primary types of FAI inspection exist, each following the core procedure but varying in scope:

• 1. Standard / Full First Article Inspection

A comprehensive check of all product characteristics. Required when:​

• A product is manufactured for the first time​
• Significant design, material, or process changes occur​
• A new supplier or facility is used

Example: A toy company launched a new action figure. They did a Full FAI to check every detail: height, paint color, joint flexibility, and safety (no small parts that could choke kids). This ensured the first batch was perfect.

• 2. Partial / Delta First Article Inspection

Focuses only on modified aspects of an existing product. Conducted when:​

• Minor design changes are made​
• Limited adjustments to materials or production steps occur​
• Core functionality of producing parts remains unchanged​

The choice depends on change scope and production risk levels.

Example: A clothing brand changed the zipper color on their jackets from silver to gold. They did a Delta FAI only on the zipper – checking color matching and durability – instead of re-inspecting the entire jacket. This saved time and cost.

Benefits of FAI Inspection

Implementing FAI offers numerous advantages, including:

• Early Error Detection: Identifying and resolving issues before mass production begins.
• Cost Savings: Reducing the need for large-scale rework or recalls.
• Improved Quality: Ensuring that products meet design specifications and quality standards.
• Regulatory Compliance: Meeting industry-specific requirements and standards.
• Enhanced Supplier-Client Relationships: Building trust through transparent quality control processes.

By incorporating FAI into your production workflow, you can achieve greater efficiency, reliability, and customer satisfaction.

Why is the Procedure Necessary?

The First Article Inspection Procedure is required in scenarios where production variables change, impacting part quality:​

• New Partners: New manufacturers may use different materials or processes, requiring verification.​
• After Initial Runs: Confirms first batches meet standards before scaling up.​
• Design Changes: Even minor modifications can affect fit, form, or function.​
• Material/Supplier Shifts: Ensures new inputs meet specifications.​
• Process/Equipment/Location Changes: Maintains consistency amid workflow adjustments.​
• Resuming Production: Reconfirms quality after long pauses.

When to Conduct the FAI Process?

Typically, an FAI will assess one component using a crucial unwritten assumption. The production procedure will be followed precisely for every next item, ensuring that high-quality parts are produced.

Any modification to the part’s design or manufacturing procedure goes against this assumption. Thus, you will need to have a first-article inspection procedure. Here are some lists of conditions that you will need to perform the first article inspection:

1.   After Having A New Contract Manufacturer or Outsource

These manufacturers might have used different raw materials. Besides, the contract manufacturer may have other product manufacturing flows. Hence, the product’s outcome may also differ from the original one. In this case, you must ensure that all the products meet your needs.

2.   After Initial Production Run

You must conduct the first article inspection procedure before manufacturing a new product. It is awful to discover that your product is unsellable after most of your products are produced. So, inspect after the first production run to avoid the waste of defective products and costs.

3.   After A Design Modification

A change in design often results in different product outcomes. You should perform the first article inspection procedure to ensure the new-designed products have zero design errors. A partial FAI is needed if only a small design is modified on the product. It is essential as the design change could impact fit, form, or function.

4.   After A Change In Materials Or Source

If the products have changes in materials or source, the parts’ specifications will differ from the original ones. You must carry out the partial or complete first article inspection procedure to confirm that the materials used meet your criteria.

5.   After A Procedure, Instrument, Or Location Change

You must undertake the first article inspection procedure if your company has recently moved to a new place or you have changed the product’s process flow or instrument. All these changes will also affect the product’s fit, form, and function. Without the first article inspection, you may face the consequences of producing faulty mass products.

6.   After The Last Run Had Ended For A Few Years

You may continue to manufacture the products after you have stopped manufacturing them for certain years. In this situation, you may have some changes in your manufacturing process or even use a new manufacturing instrument. Thus, you must conduct a first-article inspection to continue delivering a good product that satisfies customers.

How to Creat a First Article Inspection Report (FAIR)?

The FAI Report consists of 3 forms, including

• Form 1: Part Number Accountability
• Form 2: Product Accountability
• Form 3: Characteristic Accountability and Balloon Drawing.

Here are the processes of creating a first article inspection report:

Step 1: Prepare In Advance For Your FAI Inspection

Before taking your products for the first article inspection, you must prepare the needed documents. It avoids misunderstandings on the third-party inspection team and allows a smooth inspection process. Some documents that you need to prepare are:

• Engineers’ drawings: It is also called balloon drawings, where your product’s 2D or 3D design is shown along with all the dimensions
• Defining data sets for digital goods: You will need to provide these data sets to ensure the products are aligned with the correct data sets.
• Bill of materials or a list: You must include the materials and their quantity in your documents before starting the FAI Procedure.
• Process Specifications: These involve describing the product, reference standard, performance, and other related product details.
• Manufacturing planning, routing, passenger flow, and work order: These are all production planning and control information. It is needed in the documents so inspectors can control the manufacturing process.
• Information on the source or supplier: The inspector must verify if the supplier or the source is from the right channel.

Step 2: Create An Inspection Plan

Your plan should answer: What will we check? How? What’s acceptable? You will need to create the forms that describe your inspection plan. The process is as follows:

1. Indicate the need that the inspector will examine with a balloon number.
2. Fill out the AS9102 forms, the first of which is for numerical accountability and the second of which is for product accountability. You will find the details for the form on the Bill of Materials and Specifications list.
3. Make a list of the reference positions for the balloon.
4. Make a list of the requirements, which should contain the measuring units and any additional specifications that differ based on tolerances.
5. Make a list of the classes, including crucial, significant, and key criteria, before you finish the inspection plan.

Step 3: Manufacture Products

You may need to verify the factory’s quality management system before the inspection to be more confident in the results. Also, you may employ a third-party inspection company to watch over their procedure. In this step, you may start your production run.

While the product is manufactured,  the entire procedure and inspection findings are documented and recorded. You must remember that the first article is not the first thing produced but rather a randomly chosen item from the first production run.

Common Mistake: Choosing the “perfect” sample instead of a random one. Inspectors will catch this – always pick a sample from the first batch (e.g., 1 out of 50 units) to ensure it’s representative.

During production, document every step: What time was the sample made? Which machine was used? Who operated it? This traceability is key for clients.

Step 4: Obtain Data

The fourth stage is where all procedure data is collected. The parts are inspected based on the inspection plan developed in Step 2. Use calibrated tools (e.g., calipers, microscopes) to measure each characteristic. Write down the exact result (e.g., “4.98mm” instead of “close to 5mm”). If a measurement is out of range, note it as “non-conforming” and explain why (e.g., “hole diameter 4.8mm – mold needs adjustment”).

Step 5: Create The Report

You should enter your measurement results into AS9102 Form 3. In this part, you will need to fill in the following:

• Measured results
• Serial numbers of the measuring equipment used to measure the part.
• Non-conformance information
• Certificate of Conformance (C of C)
• Functional Test Report

Finally, the first article inspection report will consist of the following:

• Form 1: Lists the part number, revision, and supplier info – ensures everyone is on the same page.
• Form 2: Verifies all materials and components match the BOM.
• Form 3: Links each balloon number to its measurement result – this is the “proof” section clients care most about.

Attach supporting documents (e.g., tool calibration certificates, material CoCs) to make the report unassailable.

What if a Product Failed the First Article Inspection?

The first article inspection procedure verifies that everything is as expected before the manufacturing run starts. Suppose the product fails during the first article inspection. In that case, the production will stop, and corrective measures will be developed and implemented.

Failure of the first article inspection will happen when the inspectors find non-conformities, such as flaws, color difficulties, or even functional issues on the product. A pilot run or small initial production batch is carefully manufactured and checked with an FAI once more when production transitions back to the test condition.

Here’s a real example of how to handle it: A medical device supplier’s FAI failed because a plastic part’s thickness was 0.2mm below the requirement. They took these steps:

• Stop Production Immediately: Don’t make more defective parts.
• Find the Root Cause: The injection mold was worn – so it wasn’t pressing the plastic evenly.
• Fix the Issue: They repaired the mold and tested it with a new sample.
• Re-Run FAI: The new sample’s thickness was correct, so they resumed production.
• Update Documentation: They added a “mold inspection” step to their pre-production checklist to avoid repeats.

Pro Tip: Be transparent with your client about the failure. Most clients will appreciate you fixing the issue proactively instead of hiding it.

How to Choose a Third Party First Article Inspection Company(Avoid These Scams!)?

Doing FAI in-house is possible, but third-party companies bring impartiality and expertise – especially for regulated industries. Here’s how to pick a reliable one:

1. Check Industry Certifications

Look for companies certified to AS9102 (aerospace), ISO 9001 (general quality), or ISO 13485 (medical devices). These prove they follow global standards.

2. Ask for Case Studies

A good FAI company will share examples of how they helped clients. For example, “We caught a material defect for an automotive supplier, saving them $100,000 in rework.”

3. Verify On-Site Capabilities

Make sure they can inspect your specific part. If you make tiny electronic components, they need microscopes and precision tools – not just basic calipers.

4. Avoid “Cheap” Companies

A company offering FAI for $50 is likely cutting corners (e.g., skipping characteristics). You’ll pay more in the long run if they miss a defect.
