GROUND CONTROL
NOSE GEAR STEERING
Nose gear steering system consists of a steering horn on the nose gear leg linked to the rudder
pedals by push- pull tubes. Rudder pedal action steers the nose wheel. Gear retraction relieves
the rudder control system of its nose wheel steering and centers wheel to permit retraction into
the nose wheel well. Minimum turning radius on the ground is 40 feet (12.0 m) to the right and 48
feet (14.4 m) to the left. Adjustable steering stops have been incorporated on nose gear leg as-
sembly.
The nose wheel must not be swivelled beyond 11
left or 13
right of center. To
exceed these limits may cause structural damage.
-CAUTION-
TAXIING AND GROUND HANDLING
The aircraft can be easily taxied with minimum use of brakes. Minimum turning radius is 40 ft.
(12.0 m) right & 48 ft. (14.4 m) left, without use of brakes. A MANUAL towbar is provided to
ground handle aircraft. Care must be used to not swivel nose wheel beyond 13
right or 11
left
from center. Adjustable steering stops are incorporated on nose gear leg assembly.
Exceeding steering swivel angle limits may cause structural damage.
-CAUTION-
LANDING GEAR
CONSTRUCTION
Landing gear legs are constructed of chrome- molybdenum tubular steel, heat- treated for
greater strength and wear resistance. Main gear leg attaching points pivot in bearing surfaces on
forward and stub spars. The nose gear mounts on cabin tubular steel frame. Rubber discs in all
gear leg assemblies absorb shock of taxiing and landing.
RETRACTION SYSTEM
Landing gear is electrically retracted and extended. The landing gear switch operates a landing
gear actuator relay. Pull wheel- shaped knob out and move it to upper détente to raise landing
gear. An Airspeed Safety Relay, connected to the airspeed indicator, is incorporated into the
Garmin G1000 system and alerts the pilot to prevent landing gear retraction while on the ground
and until a safe takeoff speed (approximately 70
5 KTS) is reached. A properly rigged up- limit
switch will stop landing gear in its retracted position. Move control knob to its lower détente to
lower landing gear. A properly rigged down- limit switch will stop landing gear actuating motor
when proper force has been exerted to hold landing gear in the down- and- locked position.
Bungee springs pre- load the retraction mechanism in an over center position to assist in holding
landing gear down. A landing gear safety by- pass switch override is provided, next to the gear
switch, to allow the landing gear to retract for maintenance purposes. Depress and hold this
switch to manually by- pass airspeed safety relay and allow landing gear to retract. The electrical
extension or retraction system will not operate if the manual extension lever is not properly posi-
tioned down (refer to Emergency Extension System section).
Never rely on airspeed safety relay to keep landing gear down during taxi, takeoff
or landing. Always make certain that landing gear switch is in down position during
these operations.
-CAUTION-
WHEEL BRAKES
Main gear wheels incorporate self-adjusting, disc-type, dual puck, hydraulic brakes. The pilot’s
rudder pedals have individual toe-actuated brake cylinders linked to the rudder pedals. Depress-
