通过分析燃油箱可燃性适航条款的历次修改，对当前适航条款进行梳理，总结出符合性验证的思路，同时对比了欧美适航当局对该条款要求的异同，有助于把握正确的燃油箱可燃性研究方向，利于项目和型号设计的工作开展。

Through analyzing previous amendments of airworthiness regulations about fuel tank flammability, flammability requirements of current airworthiness regulations are researched and airworthiness compliance approaches are concluded，meanwhile the different views between U.S. and Europe authorities on this requirement are compared, which will help to develop researches of the fuel tank flammability in the correct direction, and contribute to the achievement of project and model design.
