Purpose
There are no wheel well doors. The outboard surface of the
outboard wheels have aerodynamic covers over the main
landing gear wheel well.
Location
The wheel well blade seals attach around the wheel openings in
the bottom of the main landing gear wheel well. The seals
attach to the airplane structure with bolts.
Physical Description
The wheel well blade seals consist of series of rubber bladetype
segments. The segments are held in place by a series of
seal retainers.
Functional Description
The wheel well blade seal system supplies an aerodynamic
seal around the outboard tire when the main landing gear
retracts.

General
The main landing gear shock strut uses hydraulic fluid and
compressed dry air or nitrogen to control the shock strut action.
The gas charging valve lets you pressurize the shock strut. The
oil charging valve permits hydraulic servicing of the shock strut.
The gas charging valve is on the inboard side of the main
landing gear shock strut.
The oil charging valve is on the aft side of the main landing gear
shock strut.
See the maintenance manual, servicing, for more information
about servicing the main landing gear shock strut.
Training Information Point
Obey this warning when you deflate the shock strut:
WARNING: CLEAR THE AREA BELOW THE WING BEFORE
YOU DEFLATE THE SHOCK STRUT. IF YOU
DEFLATE THE SHOCK STRUT, THE WING TIP
CAN MOVE DOWN AND CAN CAUSE INJURY TO
PERSONS OR DAMAGE TO EQUIPMENT.
NOTE: Fluid in the shock strut will have bubbles when you
release the pressure. Deflate the shock strut slowly to
prevent the leakage of the fluid through the gas valve.
Obey this warning when you remove the air valve body on the
shock strut:
WARNING: DO NOT REMOVE THE VALVE BODY UNLESS YOU
DEFLATE THE SHOCK STRUT FULLY. THE AIR
PRESSURE CAN BLOW THE VALVE BODY OUT
AND CAUSE INJURY TO PERSONS.

General
The servicing chart is on the left side of the aft bulkhead in the
main landing gear wheel well.
Use BMS 3-32 Type II landing gear shock strut fluid when you
add fluid to the shock strut. BMS 3-32 Type II fluid is a mixture of
MIL-H-5606 hydraulic fluid and additives.
You measure shock strut X dimension from the bottom face of
the outer cylinder to a rectangular raised pad on the upper
surface of the axle.
See the maintenance manual, servicing, for more information
about servicing the main landing gear shock strut.
Training Information Point
Release all air from the shock strut before you add shock strut
fluid.
CAUTION: USE ONLY THE TYPE OF FLUID WHICH IS
SPECIFIED IN THE TASK TO FILL THE SHOCK
STRUT. IF AN INCORRECT FLUID IS USED, IT CAN
CAUSE DAMAGE TO THE SEALS.
NOTE: It is optional to use fluid, MIL-H-5606 or fluid, MIL-PRF-
6083 (NATO C-635) and add lubricant, lubrizol 1395 in a
ratio of 41:1.
CAUTION: CLEAN ALL THE LEAKED HYDRAULIC FLUID
FROM THE TIRES IMMEDIATELY. THE FLUID
CAN CAUSE DAMAGE TO THE TIRES.
