Abstract：The control system of adjustable cone can ensure proper airflow into the engine. The adjustable cone often has a certain deviation from its position during external field maintenance，clearing the fault of the adjustable cone can shorten the time of maintenance. Taking the adjustable cone extension fault as the entry point，analyzing the working process of the adjustable cone，finding out the common faults of the adjustable cone，according to the composition of the adjustable cone，check the cause of the failure one by one. clarifying the troubleshooting ideas，summarizing the rules of troubleshooting，and providing reference for such faults.
Keywords：adjustable cone；inlet；engine
