Abstract:The least risk bomb location (LRBL) is the last protective screen for civil aviation safety when meeting the terrorism surprise attack with bomb. LRBL has important meaning for the safety of civil aircraft. For the current situation of civil aircraft LRBL work, there is less of detailed and clear design ways in our country. According to the suggestions from AC25.7956 and engineering design experience, the verification method of FAR 25.795(c)(1) compliance about LRBL is investigated systematically for the first time. On the one hand, through the developing of the LRBL airworthiness compliance work, we can make clear the equipment arrangement ways around the LRBL and corresponding safety analysis ways, which can strengthen the operational method of system safety analysis work. On the other hand, through the developing of aircraft structure safety analysis due to the explosive at LRBL, we can get the airworthiness compliance verification method about structure design around LRBL. This research builds verification system for compliance of FAR25.795(c)(1) about LRBL, and offers detailed and operational design ways for improving the product safety and airworthiness.
