A method for detecting play in a control surface and associated detection system which is including an aerodynamic control system, the control system including a fixed part, a movable control surface, and two servo-control blocks to cause a movement of the control surface. The method includes a play detection sequence including a command phase and a play detection phase. The command phase includes the asymmetric command of the servo-control blocks and the acquisition of an evolution, during the asymmetric command, of a force variable representative of an antagonistic force exerted in one of the servo-control blocks during the asymmetric command. The play detection phase includes the verification of a play detection condition based on the acquired evolution.
