The deicing system on the leading edge of the tail for a plane is used in the form of pneumatic mechanical method, in which deicing boot is installed at the protection area of the leading edge of the tail. The leading edge of the tail is made of double metal skin and fiber-glass reinforced composite laminate ribs. In this paper, a new installation method of deicing boot on the leading edge of the tail is introduced through improvement of the installation method of the deicing boot and confirming the structural arrangement in the leading edge of the tail The structure is simple and good in manufacture. It can meet the requirements of maintenance and interchange for the structure of the leading edge, and also meet the installation and maintenance requirements of the deicing system.
