SECTION V
LANDING GEAR AND BRAKE SYSTEM
GENERAL
The landing gear incorporated on the CH2000 is a fixed, tricycle type of gear, fitted with three
500-5 wheels (or optional 600-6 main gear wheels), using four ply tires with tubes. The nose gear
is steerable through the rudder pedals. The fixed cam automatically centers the nose wheel and
rudder in the shock extended position. (See Fig. 9) The main gear shock absorber is a mono leaf
metal spring. The two main gear wheels are equipped with single disc hydraulic brake assemblies
which are actuated by the brake pedals connected to the brake master cylinders located forward of
the rudder pedals. The brake fluid reservoirs are an integral part of the pilot side master
cylinders.
INSPECTION OF WHEELS:
When removing the wheel(s) perform Table 1 inspections “Landing Gear Group” #3, 6, 8, and 14
or annually, whichever comes first. There is no set inspection interval period for this between
inspection annuals.
REPLACEMENT OF NOSE GEAR - Fig. 9
1. Remove upper and lower engine cowl.
2. Hoist the airplane. (See Section II)
3. Remove the upper stop plate.
4. Disconnect the steering.
5. Remove the shock ring from the forward upper support.
6. Remove the lower front bearing.
7. Remove the whole nose gear assembly.
REINSTALL the nose gear assembly in reverse order of removal. Safety all connections.
Note: If for any reason the steering rod length was changed, the alignment of the nose wheel must
be checked as follows:
ALIGNMENT OF NOSE GEAR
1. Hoist the airplane. (See Section II)
2. Locate the center line of the fuselage directly behind the nose wheel assembly and
attach a plumb bob, also attach a plumb bob to the tail skid. Using the two plumb bobs
as a guide, snap a chalk line, extending several feet beyond each bob on the ground.
3. Stand in front of the nose wheel and orient the tire with the chalk line. Sight along the
center rib of the tire.
4. Adjust both rod ends at the end of the nose gear steering rod assemblies to align the
cockpit rudder pedals. Do not attempt to make the adjustment by means of one rod
end but divide the adjustment between the two rod ends. A 3/8” (10mm) minimum
thread engagement must be maintained.
5. Check the nose gear steering for travel by measuring the maximum deflection each side
from the center of the chalk line. (Fig. 18)
