欧洲民用航空安全局航空发动机适航体系

A survey of airworthiness system of EASA CS-E

针对欧洲民用航空局(EASA)航空发动机适航体系开展初步研究工作,在3个层级划分EASA适航体系的基础上,阐述EASA的航空发动机审定规范CS-E在适航体系中的地位和职责,给出CS-E的逻辑架构和演变历史,着重分析了历次修正案中的被修订条款,并进一步概括出"科技进步,灾难性事故发生,过于苛刻的适航要求,表述错误,国际一致性"5种产生规章修订的因素。

CS-E is the airworthiness standard of aircraft engine in Europe and it is under constant changing to adapt to new safety demands of airworthiness certification. In this paper, starting from the three level division of aero-engine airworthiness system of European Aviation Safety Agency （EASA）, the status and responsibility of CS-E are firstly expounded, and then the logical structure and historical amendments of CS-E are analyzed. In the analysis, the revised regulations in each amendment are particularly focused on and the revised reason of regulation can be generalized into five aspects： development of technology, hazardous accident, overly strict rules or vice versa, unclear definition or explanation, and international uniformity. Thus, this survey provides reference to the development and improvement of airworthiness system in China.
