The utility model belongs to the field of overall aerodynamic configuration design, and particularly relates to an oil supply feeler lever fairing. Curved surface front-end rectification is adopted inan existing oil-supply feeler lever cross-flow hood, installation of an oil-supply monitoring system camera and floodlight plain glass is inconvenient, the curved surface glass needs to be arranged,and the graphic processing difficulty of the camera is increased. The utility model provides an oil supply feeler lever fairing in order to reduce interference resistance and meet the installation requirements of an oil supply monitoring system camera and a floodlight at the same time. The device comprises an upper fairing and a lower fairing which are integrated, an oil supply feeler lever is contained in the upper fairing, and the outlet direction is parallel to the symmetry plane of an airplane and inclines downwards by 3 degrees; the front end of the lower fairing comprises a left inclinedface and a right inclined face, the forefront ends of the left inclined face and the right inclined face are provided with smooth transition faces, one of the camera and the floodlight is installed on the left inclined face, and the other one of the camera and the floodlight is installed on the right inclined face. Finished product installation requirements and pneumatic and flight quality requirements are effectively considered.
