2. Component Location
__________________
The MLG (Ref. 32-11-00) is in the wing between the rear spar and gear rib 5 at zones 730 and 740. They support the aircraft on the ground and absorb loads during landing, take off and taxi.
3. System Description
__________________
The MLG includes these parts:
-
a MLG shock absorber
-
a side stay assembly which includes a lock stay
-
a retraction actuator
-electrical and hydraulic dressings
-a torque-link damper.
The MLG legs have twin wheels, each wheel has a multi-disc brake unit (Ref. 32-40-00).

Operation/Control and Indicating
________________________________
The extension and retraction system (Ref. 32-30-00):
-extends and retracts the landing gear
- opens and closes the related doors (Ref. 32-12-00).
Proximity sensors on the MLG and the MLG doors give position data to the Landing Gear Control and Interface Unit (LGCIU).
Each MLG has three doors (Ref. 32-12-00):

_____________________________________
1. General
_______
The main landing gear (MLG) has two leg assemblies. The MLG legs, each with a twin-wheel assembly, are installed in the wings. They retract inboard into bays in the fuselage. The MLG supports the aircraft on the ground and (through the shock absorbers in the legs) absorbs the loads during landing, take-off and taxiing. When an MLG is extended, a side-stay assembly prevents sideways movement of the MLG and helps keep it extended.
