Faulty Cabin Lighting Wiring Alleged in Falcon 50s

A proposed AD calls for inspections to detect improperly installed wiring for optional cabin lighting that could cause fires in Falcon 50s. The FAA, which cited no incidents attributed to the alleged problem, said the wiring may be directly connected to the battery bus instead of through a dedicated circuit breaker. In this configuration, an electrical current continues to be generated after the electrical system is switched off, according to the agency. The directive would cover 175 U.S.-registered Falcon 50s (S/N 2 through 270).
