7.13 LANDING GEAR
Three landing gear use Parker 6.00 x 6 wheels. Each main gear are equipped
with a single hydraulically operated external caliper & disc brake assembly. All
three wheels use 6.00 x 6, four-ply rating, Type HI tires with tubes.
A spring device is incorporated in the rudder pedal torque tube assembly
to provide rudder trim. By using the rudder pedals and brakes, the nose gear is
steerable through a 20 degree arc each side of center. A shimmy dampener is also
included in the nose gear.
The three struts are of the air-oil type, with a normal extension of 3.25
inches for the nose gear and 4.50 inches for the main gear.
The brake system consists of dual toe brakes attached to the rudder pedals
and a hand brake lever located below, behind, and to the left of the throttle
quadrant. The toe and hand brakes have their own master brake cylinders, but
they share a common reservoir. The brake fluid reservoir is installed on the
•
top left front face of the firewall. The parking brake is incorporated in to the
hand lever master cylinder and is actuated by pulling back on the brake lever,
depressing the knob attached to the left side of the handle, and releasing the hand
brake lever. To release the parking brake, pull back on the hand brake lever to
disengage the catch mechanism and allow the handle to swing forward (refer to
Figure 7-1) .
