The fault recording and reporting method

The patent-pending Fault Recording and Reporting Method uses a large amount of diverse information output from various line-replaceable units (LRUs) and other components of the aircraft during a mission through bulk storage on electronic media. After the aircraft lands, the electronic media are removed, accessed by an appropriate apparatus, and presented in a format that can be read with a personal computer (PC). This information provides the user, typically a service technician, with information relating to the aircraft's flight; specifically, various fault indications provided by LRUs and other components. From this information, the service technician can determine whether or not a fault indication recorded during the flight is a legitimate fault requiring removal of the affected LRU or component for further diagnostic testing. The method significantly reduces incidents of no-fault-found (NFF) diagnostic test results and saves labor hours that would otherwise be spent testing properly operating LRUs and components. The method minimizes on-aircraft data interpretations, rendering unnecessary on-board maintenance processors and technicians for LRU troubleshooting.
