Abstract：A fault diagnosis method based on hierarchical SDG model is presented for aero engine fuel system which fault is difficult to diagnose because of its less sample. Based on the SDG method,a hierarchical strategy is adopted to reduce the search space of the fault source. According to the intrinsic link between the measured nodes forward search,to determine whether it is a compatible branch,to obtain a set of alternative fault sources. Sample illustrates the effectiveness of the method.
