Document type: 

The goal of this document is to provide the basis for a structured process to identify, analyze and resolve NFF issues. The NFF issues include providing guidance for decision making pertinent to the root causes of NFF, enabling action in an early stage of the component repair cycle, reducing costs involved with units unnecessarily removed from an aircraft (e.g. maintenance practices, operational factors, training, documentation etc.), highlighting the need for addressing the causes of NFF through component and system design, addressing the development/improvement of maintenance processes, and providing a framework for the interaction between the different domains for the users of this document (listed below) to implement their own strategies.
