SYSTEMS DESCRIPTIONS
Each main wheel is equipped with a hydraulically actuated disc-type
brake on the inboard side of the wheel.
Landing gear extension and retraction, wheel well door operation, and
up and down lock operation is accomplished by hydraulic actuators
powered by an electrically-driven hydraulic power pack (see figure 7-8).
The power pack assembly is housed within the control pedestal. Hydraulic
system fluid level may be checked by utilizing the dipstick/filler cap, on
the power pack, behind a snap-out cover panel on the right side of the
control pedestal. The system should be checked at 25-hour intervals. If the
fluid level is at or below the ADD line on the dipstick, hydraulic fluid (MIL-
H-5606) should be added.
Power pack operation is initiated by a landing gear lever, and is turned
off by a pressure switch. Two position-indicator lights are provided to
show landing gear position. The landing gear system is also equipped with
a nose gear safety switch, an emergency extension hand pump, and a gear-
up warning system.
LANDING GEAR LEVER
The landing gear lever, mounted to the left of the engine controls, has
two positions (up labeled GEAR UP and down labeled GEAR DOWN)
which give a mechanical indication of the gear position selected. From
either position, the lever must be pulled out to clear a detent before it can be
repositioned. Moving the lever out of the GEAR DOWN detent will start the
,~, hydraulic power pack and open the gear doors. Positioning the lever in the
GEAR UP position will direct hydraulic pressure to retract the landing
gear. Operation of the landing gear system to extend the gear will not begin
until the landing gear lever is repositioned in the GEAR DOWN detent.
LANDING GEAR POSITION INDICATOR LIGHTS
Two position indicator lights, mounted adjacent to the landing gear
lever, indicate that the gear is either up or down and locked. The lights are
the press-to-test type. The gear-down indicator light (green) has two
positions; with the light pushed in half way (throttle retarded and master
switch on) the gear warning system should be heard intermittently on the
airplane speaker, and with the light pushed full in, it should illuminate.
The gear-up indicator light (amber) has only one test position; with the
light pushed full in, it should illuminate. The indicator lights contain
dimming shutters for night operation.
LANDING GEAR OPERATION
To retract or extend the landing gear, pull out on the gear lever and
move it to the desired position. After the lever is positioned, the
