Abstract: A wing flap assembly, in which each flap (1, 2) has its own suspension and drive mechanism (3-6) and in which two adjacent flaps substantially in line with each other have a part (16) connected for movement with one flap and extending between two abutments (18, 19) on the other flap so that, in case of a failure or disturbance in the suspension and drive mechanism of one flap, this flap is limited in movement with respect to the adjacent flap to avoid serious distorsions and other dangerous consequences of such a failure or disturbance. Preferably the part (16) extending between the abutments is a pivoting lever, so connected to one flap that it moves therewith in a plane substantially parallel to the chord plane (8) of the flaps if one flap moves with respect to the other one.
