民机结构适航限制项目制定方法的探讨

Study of Airworthiness Limitation Items Establishment for Commercial Aircraft Structures

按破坏是否对飞机安全必需的结构完整性产生影响,对潜在的适航限制项目候选项进行分类。给出通过计算候选项目的寿命得到检查门槛值和重复检查间隔的方法,以及基于检查门槛值、重复检查间隔确定结构适航限制项目的原则。

The potential airworthiness limitation items candidates are identified according to the failure impact that could affect the structural integrity necessary for the safety of the aircraft. The airworthiness limitation items selection criterion is established based on the inspection threshold and repeat inspection interval, whose determining approach is derived from the calculated service life of the structural candidates.
