MAIN GEAR DOOR
The main gear door is mechanically linked to the main landing gear assembly and moves with the gear during extension and retraction. Each main gear door is attached to the wing structure with two hinges. The main door structure is made from a clad-aluminum alloy sheet. A nylon door brush is installed on the bottom edge of the door to create a seal between the tire and fuselage.
MAIN WHEEL BINS
Each main gear assembly retracts inward into wheel bins that are recessed into the main landing gear bay. The wheel bins isolate the wheels from the main landing gear bays and prevent tire-thrown debris from damaging the equipment located within the main landing gear bay. Each wheel bin contains a single loop overheat detection wire to provide a CAS warning should a wheel overheat. The bins can be removed to allow maintenance personnel access to the main landing gear bay.
MAIN LANDING GEAR UPLOCKS AND DOWNLOCKS
The main landing gear is held in the up-and-locked position by mechanical uplocks. With the gear extended, locking mech-anisms in the side-brace keeps lock the gear in the down position. On the ground, locking pins can be inserted into the side strut actuator.

NOSE LANDING GEAR
The Nose Landing Gear (NLG) consists of a twin wheel forward retracting, cantilever shock strut, and folding drag strut that incorporates a mechanical downlock.
The major sub-assemblies of the NLG are shock strut, retraction actuator, wheel and tire, drag brace and harness assem-blies, hydraulic hoses and taxi/landing lights.
The nose landing gear is actuated by the left hydraulic system and electrically controlled by the proximity sensor system (PSS) which includes the proximity sensor electronic unit (PSEU) and control handle. Normal operation of the landing gear extension and retraction system is initiated by selecting the desired landing gear position, UP or DOWN, using the landing gear control handle mounted on the main instrument panel.
