A support assembly (1) for guiding a flap (42) on an aircraft wing (41) during deployment of the flap is disclosed. The assembly comprises a guide track (2) defining a two-dimensional path, a cylindrical bearing follower (12) having a longitudinal axis constrained so as to follow said path during flap deployment, a shaft (23) extending from the bearing follower and, a spherical bearing coupling an end of the shaft to the bearing follower such that the bearing follower is rotatable relative to the shaft about the longitudinal axis of the bearing follower as it travels along the track. The spherical bearing also enabling rotation of the shaft about its longitudinal axis relative to the bearing follower and rotation of the shaft about a center point of the spherical bearing such that the flap is fret to move in multiple directions.
