The fairing arrangement (28) comprises a first fairing portion (32) on a win g (10) and a second fairing portion (34) on an aileron (12) which is mounted o n and angularly displaceable with respect to the wing. The fairing arrangement protrudes (28) outwardly of the aerodynamic profile S of the wing to cover part of an actuating device for the aileron. Parts of the first and second fairing portions (32, 34) are arranged to overlap each other to form a seal (45), one of said overlap parts defines an oblique sealing surface (44) whic h lies substantially in the direction of the path of movement of the aileron (12) over the normal operational range of movement of the aileron. The overl ap parts (32, 34) of the first and second fairing portions overlap each other over a normal operational range of the aileron (12) to form the seal (45) bu t do not overlap to form a seal over the remainder of the range in one of the directions of movement of the control surface.
