Servicing procedures contained in this
Section are confined to those maintenance
actions that occur with routine frequency
and require a reasonably short period of
time to accomplish.
and maintenance of aircraft systems and
components that require less frequent
attention are contained in the appropriate
sections of this manual.

HYDRAULIC SYSTEM

Reference Section 3
The hydraulic system consists of two
master brake cylinders and the necessary
hydraulic lines connecting the master
cylinders to the wheel brake cylinders.
Applying toe pressure to the rudder pedal
actuates the corresponding
cylinder, which in turn actuates the brake
caliper piston. Refer to Section Six for
brake servicing procedures.

Reference Section 4
The oils that are specified for the
lubrication system can be found in the
applicable engine Maintenance Manual. It
is recommended for all turbo aircraft that
the oil be changed every 400 hours. The
oil system contains 9 U.S. quarts.

The unfeathering pump draws oil
from the engine oil tank to actuate
the propeller.

the reduction gear box, not the
engine oil tank. If the unfeathering
pump has been operated prior to
checking the oil level in the tank,
pump the oil out of the gearbox and
into the oil tank by turning the

experience some
overboard through the vent.
The contents of the oil tank should be
checked within 10 minutes of the engine
shutdown. To do so, proceed as follows:
a. Unlock the filler cap and dipstick from
the filler neck on the oil tank.
CAUTION
Do not mix brands or types of oil,
since their chemical structures
may make them incompatible. If
different brands or types of oil
become mixed, drain and flush
the system and refill with new oil.
b. Check the oil tank contents against the
markings on the dipstick. Service as
required.
c. Compensate for the pitch attitude of
the aircraft to avoid over or under
servicing.
