An aircraft flight control disconnect mechanism between the pilot and co-pilot controls, including a pair of concentrically positioned opposed circular jaws, each jaw having either mating tapered teeth or mating tapered openings, which when the jaws are axially separated, disconnects one pilot control from the other and a rotating control sleeve concentrically aligned with and rotatably attached to one of said jaws, the sleeve including a helical cam slot surrounding a fixed roller whereby rotation of the control sleeve moves the said connected jaw toward or away from the adjacent jaw so that the two jaws are free to rotate independent of each other.
