A method for inspecting a gas turbine engine using a maintenance tool includes assembling a plurality of rail segments of a rail system of the maintenance tool within a core air flowpath of the gas turbine engine. The gas turbine engine includes a compressor section, a combustion section, and a turbine section together defining at least in part the core air flowpath. The method also includes moving a maintenance head of the maintenance tool along the plurality of rail segments of the rail system to perform maintenance operations within the core air flowpath of the gas turbine engine. 一种用于使用维护工具检查燃气涡轮发动机的方法包括在燃气涡轮发动机的核心空气流动路径内组装维护工具的轨道系统的多个轨道段。燃气涡轮发动机包括压缩机区段，燃烧区段和涡轮区段，它们一起至少部分地限定核心空气流动路径。该方法还包括沿着轨道系统的多个轨道段移动维护工具的维护头部，以在燃气涡轮发动机的核心空气流动路径内执行维护操作。
