The invention relates to a cover panel for a landing gear for an aircraft with at least one pivotal closable flap 6, 7. According to the invention the at least one flap 6, 7 is attached for swivel movement to the fuselage cell 2 of the aircraft by means of at least one multi-articulated joint 8, 9, 13 wherein the multi-articulated joint 8, 9, 13 is constructed with a number of individual joints seated on a shaft 17, similar to a piano hinge, and a mechanical play increases preferably uniformly starting from a middle individual joint 14 towards the outer individual joints 15, 16. As a result of the mechanical play which increases within the multi-articulated joint 8, 9, 13 from the middle individual joint 14 to the two outer individual joints 15, 16 in the direction of the x-axis or aircraft longitudinal axis, a substantial mechanical isolation of the cover panel from any possible fuselage cell movements is provided. The flap 7 has at least in the area of one side edge an anti-lift security mechanism 26 in order to prevent aerodynamically conditioned flapping and lifting movements of the flap 7 in the direction of the aircraft vertical axis or z-axis.
