An aircraft wing assembly typically includes control surfaces such as flaps. The support mechanism for a flap may include a guide called a cam plate 11, arranged to support a roller. An assembly tool 13 for positioning the cam plate comprises a main body 14 having a sleeve 15 at one end portion and a protrusion 16 at the other end. The sleeve incorporates a cavity adapted to receive the cam plate. The sleeve has a datum surface. Points on this datum surface are spaced from the tip of the protrusion by respective predetermined amounts. In-use, with the cam plate located in the sleeve cavity, the tool is moved until the protrusion touches a surface 12 of the rib, such that the datum surface is spaced a predetermined distance from the tip of the protrusion and at a predetermined orientation. Use of this tool automatically brings the cam plate into a required position for fitting to the wing assembly where ordinarily accurate positioning of the cam plate 11 during assembly of an aircraft wing can be problematic due to tolerance stack up.
