The aviation ladder with the locking mechanism comprises a bearing frame, an auxiliary moving mechanism, a first sleeve, a rotating rod, a second support, a motor, a locking mechanism and a cushion supporting block, the bearing frame is fixedly provided with steps and a first handrail, and the locking mechanism comprises a third groove and an electric telescopic rod. The third groove is formed in one inner wall of the third support, the electric telescopic rod penetrates through the fourth support, the fourth support is rotationally connected to the bottom of the third support, the third support is fixed to the lower end face of a supporting table, and the supporting table is rotationally connected to one side of the bearing frame. According to the aviation ladder with the locking mechanism, the fourth support and the third support can be locked together when an electric telescopic rod is connected into the fourth support in a clamped mode, after the aviation ladder is used, the electric telescopic rod shrinks and leaves the fourth support, and after the fourth support is rotated to be in a horizontal state, the electric telescopic rod extends again and bears the fourth support, so that the fourth support is supported by the electric telescopic rod; and finally, the supporting table is rotated to a vertical state, and storage is convenient.
