Abstract

The airworthiness compliance method of civil aircraft engine life-limited parts is investigated, according to the needs of type forensics for civil high bypass ratio turbofan engine in China. Engine life-limited parts are rotor and major static structural parts whose primary failure is likely to result in a hazardous engine effect. Typically, engine life-limited parts include, but are not limited to, disks, spacers, hubs, shafts, high-pressure casings, and non-redundant mount components. The safety goals for the airworthiness requirement of aircraft engine life-limited parts in European and American are analyzed. The airworthiness compliance requirement for the life evaluation of engine life-limited parts in AC33.70-1 and AMC515 are analyzed and interpreted. The key process and method of aircraft engine life-limited part airworthiness conformity test are given. The model of safe life prediction for life-limited parts is founded. The proposed method provides an important reference for making airworthiness guide for aircraft engine life-limited parts.
