Introduction: Removals of equipment from service for reasonsthat cannot be verified by the maintenance process (shop orelsewhere) are a significant burden for aircraft operators. Thisphenomenon is commonly referred to as No Fault Found (NFF).
Many other industry guidelines have been created in the pastaddressing NFF. NFF is often perceived as a shop-only problem or anindividual component reliability problem. This is not true. NFFsolutions require an inter-disciplinary effort to identify the truecauses and implement successful solutions.
This document describes the most common sources of NFF andprovides guidance to develop appropriate solutions. The sources ofNFF are spread throughout the following four domains:
•Design/Production
•Flight operations
•Line operations
•Shop operations
This report provides a holistic view of the NFF problem based onthe above domains and the following categories:
•Documentation
•Communication
•Training
•Testing
•System/Components design
Complete elimination of NFF is not a realistic expectation.However, a structured approach will help toward minimizing theeffects of NFF.
