Abstract
Aircraft cable harnesses is part of the aircraft Electrical Wiring Interconnect System (EWIS), which are installed at aircraft assembly stage. Cable bundle wirings are the basic platform that allows power delivery and data transfer, and therefore the systems functionalities can be then performed. It is reported by Federal Aviation Administration (FAA) that chafing, bend radius and arching problems caused by improper installations and maintenance contribute much to the aircraft accident. Due to the complexities of modern aircraft with large amount of cable bundles installed, it is difficulty to fast locate those wiring fault. This paper investigates the basic characteristics of the cable harnesses and the fundamental theory of Time Domain Reflectometry (TDR) first. A new model-based approach is proposed to allow fast and more accurate wiring fault location. After that, a handheld TDR cable fault tester is developed for industry use and implemented in this research. The preliminary research result shows its capacity of accurate and time-saving wiring fault location, which is helpful in aircraft assembly line and maintenance stage.
