ARINC 672:2008 PDF Download

The ARINC 672:2008 standard aims to provide a structured process for identifying, analyzing, and resolving NFF issues. NFF refers to situations where a component is removed and inspected but no fault or defect is found. The document emphasizes the importance of addressing the root causes of NFF, including maintenance practices, operational factors, training, and documentation.

The standard acknowledges that NFF issues result in unnecessary costs, such as the removal of units from an aircraft without a valid reason. It highlights the need for early action in the component repair cycle to minimize these costs. Additionally, the document emphasizes the importance of addressing the causes of NFF through component and system design, as well as the development and improvement of maintenance processes.
