Abstract One of the main uses of large firefighting/water rescue amphibious aircraft (herein after referred to as AG600 aircraft) is to meet the needs of forest firefighting missions in areas with high fire incidence such as northeast and southwest China. Its firefighting mission system is designed with a 12t water tank. CAAC believes that failure to consider emergency return landing (water) capability in aircraft development may lead to unsafe conditions. From the perspective of safety analysis of the whole aircraft, relevant analysis and evaluation are carried out on the design difficulties in setting emergency water delivery function for the firefighting type of AG600 aircraft, and solutions to improve the safety of the aircraft under failure state are proposed.
