BOMBARDIER Challenger 601-3A CL-600-2B16 Pilot Training Manual page 377

MAIN LANDING GEAR
The main landing gear consists of a main beam
that is connected to the wing structure, a trail-
ing link with an axle and main wheels, a shock
strut connecting the main beam to the trailing
link, and a hydraulic actuator (Figure 14-4).
The actuator functions as a side brace when the
gear is extended. It also incorporates an inte-
gral downlock mechanism that automatically
engages at extension. It can be unlocked only
with hydraulic pressure on the retract side of
the actuator.
A mechanical uplock engages the gear at
retraction; it is hydraulically unlocked for
gear extension.
Main Landing Gear Doors
When retracted, each main gear is partially en-
closed by a door that is mechanically linked
to the main landing gear and actuated by gear
movement (Figure 14-5).
