The importance of the aircraft electrical system fault detection is also growing because of mounting equipment and aircraft demand has increased significantly to an increase in facility that use electricity as large and modernize. This paper began to solve the case of an actual defect in the electrical system BPP that occurred in the Boeing 737-200 aircraft, developed in the 1960s and produced in 1982. In the process of supplying power through an external power station on the ground, a circuit breaker installed in the cockpit to protect the aircraft was opened, making it impossible to use external power on the ground. In this paper, reliability test procedures applied to aircraft design and existing maintenance procedures, such as BIT and automatic test equipment utilization, were studied to detect and resolve electrical system defects. A plan was established and implemented, and the test results were verified through an aircraft ground-mounted inspection.
