A method for lifting a wing of an aircraft. A plurality of lifting assemblies is attached to a mounting ring supporting the wing. A first plurality of base assemblies is attached to a plurality of fittings connected to the fuselage of the aircraft. The plurality of lifting assemblies is moved away from the first plurality of base assemblies using a plurality of biasing systems correspondingly attached to the plurality of lifting assemblies, the moving causing the mounting ring to move away from the fuselage. The first plurality of base assemblies is removed. A second plurality of base assemblies is attached to the plurality of fittings. Thereafter, moving the plurality of lifting assemblies away from the second plurality of base assemblies using the plurality of biasing systems is repeated, the repeating moving causing the mounting ring to move away from the fuselage to the first height.

Wing lift system capability expansion

A method and apparatus may be present for moving a wing. A plurality of lifting assemblies may be attached to a first plurality of channels in a ring associated with the wing of an aircraft. A plurality of base assemblies may be attached to a plurality of fittings with a second plurality of channels associated with a fuselage of the aircraft. The plurality of lifting assemblies may be moved away from the plurality of base assemblies using a plurality of biasing systems such that the ring may move away from the fuselage.
