TEXT
[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.
[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.
Fig 14-1 landing gear system
[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.
