A FAI report, commonly known as a First Article Inspection Report (FAIR), is a critical document in manufacturing that certifies that a sample part has been produced and inspected in full accordance with all of the customer's specifications and design requirements.
Understanding First Article Inspection (FAI)
Before delving into the report itself, it's important to understand the underlying process. First Article Inspection (FAI) is a systematic process that encompasses the planning, manufacturing, and verification stages of a product's initial run. It is performed on the first production run of a new part, or when significant changes occur in the design, manufacturing process, or production location. The primary goal of FAI is to confirm that all engineering, design, and specification requirements are fully met before mass production begins.
The Purpose and Significance of a FAIR
The FAIR serves as the official record and certification of this inspection process. It provides objective evidence that all features, dimensions, materials, and processes conform to the agreed-upon standards. This report is essential for:
- Quality Assurance: It ensures that the manufacturing process is capable of consistently producing parts that meet all specified requirements.
- Risk Mitigation: By identifying and rectifying non-conformities early, it prevents costly defects and recalls in large-scale production.
- Compliance: It demonstrates adherence to industry standards and customer contractual obligations, particularly in highly regulated industries such as aerospace, defense, and medical devices.
- Communication: It provides a clear, documented basis for communication between the manufacturer and the customer regarding part conformity.
Key Components of a FAI Report
While the specific format can vary, many industries, particularly aerospace, follow strict guidelines such as the AS9102 Aerospace First Article Inspection Requirement standard for FAI reporting. A typical FAIR is structured to provide comprehensive data, often divided into three main forms or sections:
Form 1: Part Number Accountability
This section identifies the part being inspected, including:
- Part number and revision level
- Part name
- Supplier information
- Customer information
- Reason for FAI (e.g., new part, design change)
Form 2: Product Accountability
This form details the materials and special processes used in manufacturing the part. It includes:
- Raw material specifications and certifications
- Treatments (e.g., heat treatment, surface finish)
- Special processes (e.g., welding, non-destructive testing) and their certifications
Form 3: Characteristic Accountability
This is often the most detailed section, listing all design characteristics that require verification. For each characteristic (e.g., dimension, tolerance, feature):
- Balloon Number/Characteristic Number: Links to a drawing or model.
- Reference Location: Where on the drawing the characteristic is found.
- Requirement: The nominal dimension or specification.
- Tolerance: The allowed deviation.
- Measurement Result: The actual measured value.
- Gage Used: The inspection tool used.
- Accept/Reject Status: Whether the characteristic passed or failed.
When is a FAI Report Required?
A FAIR is typically required in several scenarios to ensure product quality and compliance:
- New Part Introduction: When a new part is being manufactured for the first time.
- Design Changes: Modifications to the part's design that affect fit, form, or function.
- Process Changes: Significant alterations to the manufacturing process, tooling, or equipment.
- Relocation of Manufacturing: Moving production to a new facility or supplier.
- Extended Production Break: After a prolonged period of no production (often 2+ years).
In essence, the FAI report is the definitive proof that the initial production run has successfully validated the manufacturing process against all customer requirements, paving the way for full-scale, compliant production.
