Claim:
1. A device for an adjustable flap adjustably mounted on a main wing surface of an airplane wing, the device comprising: at least one adjustment unit configured to adjust the adjustable flap, wherein the at least one adjustment unit has an actuator arranged, on the main wing surface and a kinematic adjustment mechanism running between the actuator and the adjustable flap, wherein the adjustable flap is mechanically coupled with the actuator via the kinematic adjustment mechanism; and at least one damping unit configured to damp a dynamic loading effected by the adjustable flap on the adjustment unit due to a critical malfunction event occurring in a region of the adjustable flap, wherein the at least one damping unit is arranged between the main wing surface and the adjustable flap, wherein the at least one damping unit comprises a passive damper which comprises a damping characteristic configured to effect no substantial damping of an adjustment movement of the adjustable flap under normal flight conditions, but which damps out any suddenly occurring dynamic loading exerted by the adjustable flap onto the adjustment unit, and wherein the damping unit is located at substantially a same wingspan location as the adjustment unit with respect to a wingspan direction of the airplane wing.
