从事故角度浅谈飞机结构设计理念及规章

On the source of aircraft structure design regulations from the perspective of accident

2017年交通部发布了《CCAR121大型飞机公共航空运输承运人运行合格审定规则》R5版本,其中维修体系的主要变动为附件J:持续适航和安全改进,民航局审定司同时发布/修订了8个相应咨询通告。其中重点规章为《AC-121-FS-2018-71修理和改装的损伤容限检查要求》。通过民航史上关键事故,介绍并阐述规章和咨询通告中"安全寿命"、"损伤安全"和最终发展为"损伤容限"的历史及落实到附件J和咨询通告的相应条款,为业内人员提供借鉴,加深对于飞机结构安全设计理念和规章理解。

In 2017,the Ministry of Transport issued the R5 version of the CCAR121 Large Aircraft Public Air Transport Carrier Operational Certification Rules.The main changes in the maintenance system exist in Annex J:Continuous Airworthiness and Safety Improvement.Department of Aircraft Airworthiness Certification of Civil Aviation Administration of China also issued or revised 8 corresponding advisory notices.Among them,the "Injury Tolerance Inspection Requirements for AC-121-FS-2018-71 Repair and Modification" is the key one.This paper introduces and expounds the history of "safely life", "damage safely" and the final development of "damage tolerance" in regulations and advisory notices through key accidents in civil aviation history,and partially implements the corresponding provisions of Annex J and advisory circulars,which could provide reference for the designers and the professional personnel and deepen the understanding of the aircraft structural safety design concept.
