Abstract
An airplane jack apparatus for lifting a flat main spring landing gear includes a base that supports a hydraulic jack and an upright member, to which a lift arm is pivotably attached. The lift arm has a rotatable cross member that engages a piston that raises out of the hydraulic jack, and the lift arm has a horizontal lifting portion that engages the ground-facing end of a landing gear. The base of the airplane jack apparatus has wheels to allow the jack to move as the angle of a landing gear changes while being lifted.
