The invention relates to the technical field of mechanical structures, in particular to a light helicopter fuselage which comprises a shell, a fuselage truss is arranged in the shell, and a fuel tank is mounted in the fuselage truss; engine cabin doors are arranged on the two sides of the shell; a fairing is detachably installed at the bottom of the shell in a clamped mode; and a tail beam is arranged at the rear end of the shell. The fairing comprises a front fairing body and a rear fairing body, and the front fairing body and the rear fairing body are fixed to the bottom of the shell through arranged lock catches. According to the light helicopter fuselage, the fairing is detachably arranged at the bottom of the shell, so that the fairing can be conveniently disassembled to overhaul a fuel tank, an engine and other parts installed in the shell, meanwhile, the overall stability of the shell is improved through the fuselage truss, and external protection can be provided for the fuel tank.
