(cold engine). Fill to MAX or MAX HOT (hot engine).
Check oil filler cap for damaged
preformed packing, general condition and locking.
Ensure that oil filler cap is correctly
prevent loss of oil and possible engine
Install and secure oil filler cap.
Check for any oil leaks.
2-95. SERVICING THE HYDRAUL IC SYSTEM.
Remove brake reservoir cap and fill
reservoir to washer on dipstick with hydraulic fluid.
Install brake reservoir cap.
Servicing Hydraulic Landing Gear System.
retraction system consists of maintaining the correct
fluid level and maintaining the correct accumulator
precharge. The accumulator is located in the reservoir
access area and is charged to 800 50 PSI using
bottled nitrogen. A charging gage is mounted on the
accumulator. A reservoir, located just inboard of the left
nacelle and forward of the main spar, has a lid with a
dipstick attached marked FLUID TEMP 0° F, 50° F,
100° F. Add MIL-H-5606 hydraulic fluid (consumable
materials list) as required to fill the system, corrected for
2-96. INFLATING TIRES.
Inflate tires as follows:
Inflate nose wheel tires to a pressure
between 55 and 60 PSI.
Inflate main wheel tires to a pressure
between 73 and 77 PSI.
2-97. SERVICING THE CHEMICAL TOILET.
The toilet should be seviced during routine ground
maintenance of the aircraft following every usage.
The waste storage container should be removed,
emptied, its disposable plastic liner replaced, and the
container replaced in the toilet cabinet. Toilet paper,
waste container plastic liners, and dry chemical
deodorant packets should also be resupplied within the
toilet cabinet as needed.
Servicing the air conditioning system consists of
checking and maintaining the correct refrigerant level,
compressor oil level, belt tension and condition, system
leak detection, and replacement of the evaporator air
filters. It is imperative that maintenance of the air
conditioning system, except for filter replacement, be
accomplished only by qualified refrigerant system
Do not apply anti-icing, deicing, and
defrosting fluid to exposed aircraft
surfaces if snow is expected. Melting
snow will dilute the defrosting fluid
and form a slush mixture which will
freeze in place and become difficult to
The aircraft is protected in subfreezing weather by
spraying the surfaces (to be covered with protective
covers) with defrosting fluid. Spraying defrosting fluid
on aircraft surfaces before installing protective covers
will permit protective covers to be removed with a
minimum of sticking. To prevent freezing rain and snow
from blowing under protective covers and diluting the
fluid, ensure that protective covers are fitted tightly. As
a deicing measure, keep exposed aircraft surface wet
with fluid for protection against frost.
Use undiluted anti-icing, deicing, and defrosting
fluid (MIL-A-8243) to treat aircraft surfaces for protection
against freezing rain and frost. Spray aircraft surface
sufficiently to wet area, but without excessive drainage.
A fine spray is recommended to prevent waste. Use
diluted, hot fluid to remove ice accumulations.
Remove frost or ice accumulations from
aircraft surfaces by spraying with diluted anti-icing,
deicing, and defrosting fluid mixed in accordance with
