Abstract: A case-based fault diagnosis expert system project is presented, in which the knowledge is described by production rule and programmed by a method of sub-space dividing, and the knowledge expressing, the inferring mechanism and the self-recognition system are all case-based. The blackboard approach is used while reasoning. A case-based helicopter fault diagnosis expert system designed and realized as above has been used for helicopters of some type, which adjusts to the current demands of the helicopters maintaining and should be widely used in the helicopter fault diagnosis
