Tires. The aircraft is equipped with dual 22 x
6.75 x 10, 8 ply rated, tubeless, rim inflation tires on the
main gear. The nose gear is equipped with a single 22 x
6.75 x 10, 8 ply rated, tubeless, rim inflated tire.
k.
Steerable Nose Wheel. The aircraft can be
maneuvered on the ground by the steerable nose wheel
system. Direct linkage from the rudder pedals (fig. 2-7)
to the nose wheel steering linkage allows the nose wheel
to be turned 12° to the left of center or 14° to the right.
When rudder pedal steering is augmented by the main
wheel braking action, the nose wheel can be deflected
up to 480 either side of center. Shock loads which
would normally be transmitted to the rudder pedals are
absorbed by a spring mechanism in the steering linkage.
Retraction of the landing gear automatically centers the
nose wheel and disengages the steering linkage from
the rudder pedals.
I.
Wheel Brake System. The main wheels are
equipped with multiple-disc hydraulic brakes actuated by
master cylinders attached to the rudder pedals at the
pilot's and copilot's position. Braking is permitted from
either set of rudder pedals. Brake fluid is supplied to the
system from the reservoir in the nose compartment.
The toe brake sections of the rudder pedals are
connected to the master cylinders which actuate the
system for the corresponding wheels. No emergency
brake system is provided.
WARNING
Repeated
and
excessive
application of brakes, without
allowing
sufficient
time
for
cooling,
between
applications,
will cause a loss of braking
efficiency,
possible
failure
of
brake or wheel structure, possible
blowout of tires, and in extreme
cases may cause the wheel brake
assembly to be destroyed by fire.

PARKING BRAKE.
Dual parking brake valves are installed below
the cockpit floor. Both valves can be closed
simultaneously by pressing both brake pedals to build up
pressure, then pulling out the handle placarded
PARKING BRAKE, on the left subpanel. Pulling the
handle fully out sets the check valves in the system and
any pressure being applied by the toe brakes is
maintained. Parking brakes are released when the
brake handle is pushed in. The parking brake may be
set from either cockpit position.
CAUTION
Parking brakes shall not be set
during flight.
