First Article Inspection: Definition, Report Template, and Process

First Article Inspection (FAI) is a critical component in the manufacturing process, ensuring that newly produced parts meet the required specifications and standards before mass production begins. This article delves into the definition of FAI, provides a detailed report template, and outlines the essential steps in the FAI process.

Definition of First Article Inspection

First Article Inspection is a quality control process used to verify that the first production part or sample, known as the “first article,” conforms to the design specifications and requirements. This inspection is conducted before the commencement of full-scale production to ensure that the manufacturing process and production equipment are set up correctly. The primary objective of FAI is to identify and rectify any deviations from the design early in the production cycle, thus preventing costly rework or defects in subsequent parts.

What is the Purpose of FAI?

The purpose of FAI is to inspect a sample of the first product produced in a batch to verify that it adheres to the correct specifications and customer requirements. This process helps identify any issues early, ensuring that manufacturing processes are correctly set up and capable of consistently producing parts that meet quality standards.

What Happens If a Parts Passes or Fails the First Article Inspection?

If a component passes the FAI, production resumes, having confirmed that it meets all expectations. However, if a part fails, production halts until the cause of the failure is identified and corrected. Once issues are addressed, a new FAI is conducted to verify if production can restart. This process is crucial in industries such as defense, aerospace, and medical devices, where precision is vital. Specific sectors may have detailed FAI requirements, such as the AS9102 standard, which provides evidence of quality compliance and accountability throughout the supply chain.

What Situations Call for a First Article Inspection?

When starting production of a new part, or when changes are made to an existing part’s design or production process. Full FAIs are required for new parts, new suppliers, or if there has been a production hiatus of three years or more, conducting an FAI is essential to validate the manufacturing process before it resumes. Similarly, any changes in materials, sourcing, manufacturing processes, tools, or production locations necessitate an FAI.

In industries with stringent quality requirements, such as aerospace, defense, and medical devices, an FAI is crucial to verify that all parts meet the exacting standards required for critical applications. An FAI helps to prevent costly production errors and ensures that parts consistently meet quality and performance specifications.

First Article Inspection Report

A First Article Inspection Report (FAIR) is a critical document that confirms a product has been manufactured according to the required specifications. In the aerospace and defense industries, the FAIR must include three specific forms, each serving a distinct purpose:

1. Form One: Part Number Accountability – This form identifies the part being inspected, along with any related sub-assemblies or detail parts.
2. Form Two: Product Accountability – This form outlines all materials, specifications, processes, and functional tests required by the design.
3. Form Three: Characteristic Accountability – This form details each design characteristic of the inspected part, including dimensions, tolerances, and measurements. It also requires a Balloon Drawing, or Bubble Drawing, which supports this form by linking each design characteristic to its corresponding number.

Additional details in the FAIR typically include the part name and number, the name and signature of the inspector, the date of completion, and customer approval. The FAIR ensures that all parts meet design requirements before full production continues.

Tools for First Article Inspection

For effective First Article Inspection (FAI), a range of tools and equipment is used to ensure the parts meet the required specifications and standards. These tools help measure, verify, and document the quality and accuracy of the parts being inspected. Here are some commonly used tools for FAI:

Measurement Tools

Vernier and digital calipers measure internal and external dimensions, as well as depths, while micrometers provide highly accurate measurements of thicknesses and diameters. Height gauges are used to measure vertical dimensions and check heights relative to a reference plane. Dial indicators help detect small variations in dimensions or run-out, ensuring that parts meet the desired specifications.

Inspection Equipment

Coordinate Measuring Machines (CMMs) are crucial for assessing the physical geometrical characteristics of parts. CMMs use probes to touch the part’s surface and obtain precise measurements. Optical comparators project magnified images of parts onto a screen, allowing for comparison with design drawings to inspect dimensional accuracy. Surface plates offer a flat and stable reference surface for measuring and checking flatness. Gage blocks provide precise length standards for calibrating measuring instruments and verifying measurements.

Functional Testing Tools

To ensure parts meet functional requirements, torque wrenches are used to verify that fasteners are tightened to specified values. Pressure testers assess the ability of parts to withstand designated pressures, which is vital for hydraulic or pneumatic components. Electrical testing equipment, such as multimeters and oscilloscopes, is used to check the electrical characteristics and functionality of parts with electrical components.

Visual Inspection Tools

Magnifying glasses aid in examining parts for surface defects and anomalies, while borescopes allow for internal inspections of hard-to-reach areas. High-resolution cameras capture detailed images for thorough visual examination and documentation.

Documentation Tools

FAI report templates standardize the documentation of inspection results, including measurements and test outcomes. Data collection software automates the recording and analysis of inspection data, facilitating accurate and efficient reporting. Calibration certificates are essential for verifying that measurement tools and equipment are calibrated correctly, ensuring the accuracy of the inspection results.

Process of First Article Inspection

The First Article Inspection (FAI) process is a crucial quality assurance step that ensures a product meets design specifications before mass production. Here’s an overview of the FAI process:

1. Review of Design Documentation: This initial step involves thoroughly examining design documents, including engineering drawings, CAD models, and specifications. These documents guide the manufacturing process and identify key inspection requirements, such as critical dimensions and surface finish.
2. Manufacturing of the First Article: After reviewing the design, the first article is manufactured. This step includes setting up machines, calibrating equipment, and arranging tools and materials according to the design specifications.
3. In-depth Inspection of the First Article: The manufactured first article undergoes a detailed inspection. This involves checking dimensions, surface finish, and any special requirements outlined in the design. Inspection tools such as Coordinate Measuring Machines (CMMs) are used to ensure the part meets the specifications.
4. Implementing Corrective Actions: If defects or deviations are found during the inspection, corrective actions are taken. This includes analyzing the causes of defects, adjusting manufacturing processes, and making necessary improvements.
5. Verification and Validation: A second article is produced to verify that the corrective actions were effective. This step includes repeating the inspection process to ensure that the defects have been addressed.
6. Approving for Mass Production: Upon successful verification, the product is approved for mass production. This final step confirms that the manufacturing process is capable of consistently producing parts that meet quality standards.

The FAI process ensures that all aspects of production are thoroughly vetted and optimized, leading to high-quality and reliable products.
