The invention belongs to the technical field of aircraft system tests, and particularly relates to an airborne PHM system fault diagnosis function test method. The method comprises the following steps: S1, selecting a test fault sample covering all fault modes which can be diagnosed by an airborne PHM system; s2, for each test fault sample, determining a fault simulation method of the fault sample; s3, giving a specific fault diagnosis qualification criterion for each test fault sample; s4, performing at least one time of fault simulation on each test fault sample according to the fault simulation method, and determining a fault diagnosis result; and S5, giving a test conclusion whether the test is qualified or not based on the fault diagnosis qualification criterion and the fault diagnosis result. The airborne PHM system fault diagnosis function test method provided by the invention can guide the development of the airborne PHM system fault diagnosis function test.
