The invention discloses an auxiliary lifting assembly, an airplane hatch adopting the auxiliary lifting assembly, and an airplane. The auxiliary lifting assembly comprises a limiting stage and an auxiliary lifting mechanism; one end of the auxiliary lifting mechanism is connected with a latch shaft, and can rotate along with the latch shaft; the other end of the auxiliary lifting mechanism is pivoted to the airplane hatch, and is positioned on the limiting stage; the limiting stage is used for limiting the position of the auxiliary lifting mechanism, and the position is the limiting position; when rotating, the latch shaft drives the auxiliary lifting mechanism to move, the auxiliary lifting mechanism is limited by the limiting stage after moving to the limiting position, and a lifting power in the axial direction of the auxiliary lifting mechanism is provided for the latch shaft in the continuous rotation process of the latch shaft; the latch shaft transmits the power to a latch assembly to enable the latch assembly to be suspended in a latch groove. Through the auxiliary lifting component provided by the invention, the latch assembly can be suspended in the latch groove, so that mutual abrasion between a latch and the latch groove is prevented.
