(1) the landing gear consists of two main gear and a nose gear. The main gear are located inboard of each engine, aft of the rear wing spar. The nose gear is located below the aft bulkhead of the flight compartment. Braking is provided by four brake assemblies, one mounted on each main gear wheel. Landing gear control and indication components located in the flight compartment include: the landing gear selector lever and indication lights, manual extension handles, parking brake lever and indicator, nose gear steering control wheel, antiskid control switch and inoperative indicator, and the autobrake control switch and disarm indicator.
起落架包括兩個主起落架和一個前起落架。主起落架位于每臺發動機內側，翼尾梁后部。前起落架位于駕駛艙后壓力隔板下方。剎車系統由四個剎車組件組成，一個安裝在每個主起落架艙。起落架控制及指示組件安裝在駕駛艙，包括：起落架選擇手柄和指示燈，人工釋放手柄，停留剎車手柄及指示器，前輪控制器，防滑控制開關及無效指示器，及自動剎車控制及解除預位控制。
(2) The landing gear is hydraulically actuated to extend and retract by means of a landing gear selector lever located on the center instrument panel (P2-2).when the selector lever is placed in the UP position, all three gear retract. Each main gear retracts into the fuselage. The nose gear retracts into the nose wheel well. When the selector lever is placed in the DOWN position, all three gear extend. The OFF position is the normal cruise mode and all landing gear are locked up and depressurized. A solenoid lock system restricts the selector lever to the UP position when the airplane is on the ground .

起落架借助于位于中央控制面板 P2-2的起落架選擇手柄通過液壓作動進行起落架收放操作。當起落架控制手柄置于“ UP”位時，三個起落架收起。各主起落架收起到機身內；前起落架收起到前輪艙。當控制手柄置于“ DOWN”位時，三個起落架放下。置于“ OFF”位為正常巡航模式，起落架鎖好并釋壓。當飛機在地面時，一個電磁鎖系統限定控制手柄在“ UP”位。

(3) Six lights located above the landing gear selector lever provide indication and warning for the landing gear. A green light is illuminated when the respective gear is down and locked .the red light is illuminated when the landing gear is in transit or the landing gear lever and the landing gear do not agree. The red lights also serve as warning lights when the airplane is in a possible landing configuration and the gear is not down and locked.
