Fire protection performance is one of the most important capabilities for aircraft engine, since the result may be hazardous in the case of a fire condition. According to fire protection regulation CCAR 33.17 of China Civil Aviation Regulations, fire-proof tests of a specific pipeline, a fuel tank and a fuel filter assembly were carried out. Test conditions include inlet fluid temperature, fluid pressure, fluid volume flow, fire temperature and heat flux density. The average flame temperature during the fire tests is 2000 degrees Fahrenheit, the heat flux density is 116kW/m2±10kW/m2 and the distance from burner exhaust to the test area is 100mm in these fire tests. Fire test of pipe passed, but the fire test of oil tank failed because of the failure of the oil circulation system and the melting of plastic pipe material in the ventilation pipe separately. The first fire test of the fuel filter failed because of design defect of one oil drainage path, but after design change of the oil drainage path, the second one succeeded. Based on the fire protection tests and results analysis, three essential factors of fire protection performance and type certification were presented: 1. Volume of medium retained in test parts; 2. Mass flow of medium; 3. Pressure in the test parts cavity.
