| Abstract: | A turboshaft engine often occurred oil leakage from exhaust nozzle during development. A fault tree was set based on principle analysis of oil system. It analyzed each possible causes of leakage. Combined with methods as disassembly inspection and component measuring on related parts and oil pump, the failure cause is located. The solving solution was set aimed at the failure cause. |
