Objective:

A formal process to verify that a new or changed production process can produce a part that complies with all engineering design specifications and requirements.

How it’s used:

One or more initial parts from the first production run are meticulously measured and inspected against all drawing characteristics, specifications, and other requirements. The results are documented in an FAI report.

Pros

Verifies that the production process is capable of producing conforming parts; Identifies any discrepancies between design and actual part before full production; Provides objective evidence of conformity.

Cons

Can be time-consuming and costly, especially for complex parts with many characteristics; Requires precise measurement equipment and skilled inspectors; Only inspects a sample from the first run, ongoing process control is still needed.

Categories:

Manufacturing, Quality

Best for:

Validating that a manufacturing process is set up correctly and can produce parts to the required specifications, typically for new products or after significant process/design changes.

First Article Inspection (FAI) methodology is commonly utilized in aerospace, automotive, and electronics industries, where precision and adherence to specifications are paramount due to safety and regulatory standards. In these sectors, FAI is typically initiated during the pre-production phase when a new part or system is introduced, particularly after any significant design or process alterations. Key participants in the FAI process include design engineers, quality assurance teams, and manufacturing personnel, who collectively ensure that the initial samples align with the technical drawings and specifications. This methodology can prove particularly beneficial in validating automated manufacturing processes, as it identifies potential issues before mass production begins, thus reducing the risk of costly recalls or reworks. The FAI report serves as a comprehensive documentation that provides traceability for production decisions and can also be a requirement for compliance with industry standards like AS9102 for aerospace components. For organizations that prioritize continuous improvement, FAI is a preventative measure that promotes efficiency by highlighting discrepancies early on. Furthermore, its implementation can support design verification and facilitate communication across interdisciplinary teams, ensuring that all stakeholders have a clear and shared understanding of product specifications and quality requirements before full-scale production commences.

Key steps of this methodology

Identify all drawing characteristics, specifications, and requirements for the part.
Measure initial parts from the first production run against the identified specifications.
Inspect the parts for any non-conformances or discrepancies.
Document all measurements and inspection results in the FAI report.
Review and analyze the FAI report for compliance with specifications.
Implement corrective actions if any non-conformances are found.
Validate the manufacturing process based on FAI results before full-scale production.

Pro Tips

Implement a risk-based approach by prioritizing the inspection of characteristics that are most likely to affect product functionality or compliance.
Utilize advanced measurement technologies, such as laser scanning or high-resolution imaging, to increase accuracy and reduce measurement variability.
Conduct a cross-functional review of the FAI findings with design, manufacturing, and quality teams to enhance collaborative problem-solving and corrective actions.
