The verification of lightning protection for the fuel system of transport aircraft is an im-portant part of aircraft airworthiness verification.This article introduces the airworthiness require-ments for lightning protection in fuel systems of transport aircraft and the characteristics of two air-worthiness compliance verification methods.It also introduces the airworthiness compliance test veri-fication process for lightning protection in fuel systems of general transport aircraft.The test require-ments,combustible gas ratio,standard ignition source and other testing equipment for the combustible gas method test of lightning protection were studied,and the verification of combustible gas ignition threshold and the process of combustible gas method test were also proposed that,provides a refer-ence for the development of such test verification.
