What is First Article Inspection (FAI)?

FAI is an official design inspection that verifies a manufacturing process that can reliably and repeatedly produce a part or set of parts for mass production.

When a manufacturer begins creating a part, the company has various quality control methods from prototypes to pre-production to ensure a capable process that can produce a part of correct quality.

FAI inspects an actual production unit from a first run to ensure the product design matches the production part through handheld inspection methods, coordinate measure machines (CMM), scanners or a variety of other measurement techniques.

For aerospace and other high-value assets, this can be a single part. For lower value parts like appliances and electronics, this can be a set of parts.

The FAI report reviews the production process, documentation, and tooling, especially, dimensional properties that are not within tolerance and do not meet requirements.

What’s the Purpose of a First Article Inspection?

FAI is important for verifying not only the part but also the ability of the supplier/production team to meet the standards of the manufacturer/customer.

FAI benefits both the customer and supplier by having a structured agreement and communication for setting expectations about process and product from both parties.

In the manufacturing world, limiting defects and taking corrective action earlier in the process than later provides exponential savings in rework, scrap, and the dreaded recall. Every manufacturer’s goal is to have a reliable and repeatable process, and FAI enforces that standard.

Common problems FAI detects:

  • Incorrect or ambiguous product design.
  • Wrong or inconsistent quality of material.
  • Wrong or poor production process (e.g. equipment).
  • Inconsistent quality control.

Who does the First Article Inspection and When is It Required?

In general, suppliers or production team create the FAI report for the customer to review.

FAI is typically required for the following items:

  1. First production run of a new product.
  2. Changes in product: design, materials, and function.
  3. Changes in process: method, tools, location, and inspection criteria.
  4. More than 2 years since the part was produced.

How to Create First Article Inspection Report (FAIR)?

Different industries have different names, standards, and methods to their FAIR:

For simple parts, an FAI report can be short; however, complex parts may be lengthy, technical, and in-depth.

What’s Included in a FAIR?

  1. Guideline for engineering design requirements are verified and documented.
  2. Manufacturing process and part is capable and consistent.
  3. Validation of drawing, tool, and revision accuracy.
  4. Accurate dimensional & other quality properties: Position of holes, distance between edges, diameter and shapes of holes, material, electrical, weight, density, stiffness, color, surface finish, etc.
  5. Clear understanding and communication between purchaser and supplier.

First Article Inspection Report Sample, Form, and Template

AS9102 FAIR (consists of three forms):

  • Form 1: Part number accountability product and associated FAI. Here's where you find general info about the part, the FAI itself, and Bill of Materials (BoM).
  • Form 2: Product accountability - materials, but also special processes, and functional testing.
  • Form 3: Characteristic accountability - characteristic accountability, verification, and compatibility evaluation. Here's Here's where you find all GD&T that is inspected.

First Article Inspection Software

FAIR are usually done in three ways: manually (pen and paper), digitally (2D PDF, Adobe Acrobat, and Microsoft Excel), or with inspection software which uses optical character recognition (OCR) to recognize engineering symbols directly from the drawing to create balloons with unique IDs.

However, those 3 methods are based on 2D drawings and are dependent on a human process, when automatic generation of a FAI, PPAP, or inspection planning can be done through model-based definition (MBD).

MBD First Article Inspection

MBD is a growing industry practice of having the 3D CAD model be the “single source of truth.”

This means the CAD model along with semantic product and manufacturing information (PMI) can drive the FAI report, GD&T, bill of materials, notes, engineering change orders etc. for an improved method of inspection generation and other manual processes that can be automated.

The power of MBD FAI is the human and machine readability factor. With 2D drawings, data is for human consumption which presents two major problems: reliance on human process & interpretation and data that is underutilized.

For example, if a large company with multiple suppliers receive the same drawing, most likely, the company will get back 5 different FAIs with different GD&T interpretations from the suppliers.

MBD FAI coming from the company first establishes the specification of the process and product more explicitly which ensures uniformity between different suppliers.

Also, quality and inspection teams are often viewed as pass/fail departments, yet they have valuable data that can help improve business products and problems.

MBD introduces data back into the ecosystem for improved designs, improved parts, and improved operations done quicker, cheaper, and more efficiently.

MBD FAI Benefits:

  1. Automated: No need for human transcription or interpretation.
  2. Build and optimize a reliable and repeatable process.
  3. Data mapped back to the single source of truth.
  4. Start of the digital transformation from design to manufacturing.
  5. Valuable data to mined for analytics and business insights.
