the rear spar and at an auxiliary front spar.
The wing airfoil section is a laminar flow type, NACA659-
415 with the maximum thickness about 40% aft of the leading
edge. This permits the main spar carry-through structure to be
located under the rear seat providing unobstructed cabin floor
space ahead of the rear seat.
LANDING GEAR
The three landing gears use a Cleveland 6.00 x 6 wheel, the
main wheels being provided with Cleveland single disc hydraulic
brake assemblies, No. 30-55. All wheels use 6.00 x 6 four ply
tires with tubes.
The nose gear is steerable through a 44 degree arc by use of
the rudder pedals. A spring device is incorporated in the rudder
pedal torque tube assembly to aid in rudder centering and to
provide rudder trim. The nose gear steering mechanism also in-
corporates a hydraulic shimmy dampener.
The three struts are of the air-oil type, with the normal
extension being 3.25 inches for the nose gear and 4.50 inches
for the main gear.
The standard brake system for the Cherokee consists of a
hand lever and master cylinder which is located below and behind
the left center of the instrument sub-panel. The brake fluid
reservoir is installed on the top left front face of the firewall.
The parking brake is incorporated in the master cylinder and is
actuated by pulling back on the brake lever, depressing the knob
attached to the handle and releasing the brake lever. To release
the parking brake, pull back on the lever to disengage the catch
mechanism and allow the handle to swing forward.
Optional toe brakes are available to supplement the standard
hand lever and parking brake system.
