LANDING GEAR

The tri-cycle landing gear system is hydraulically actuated and each
landing gear is equipped with a single wheel. The nose landing gear uses
an air/oil shock strut and has a steer-by-wire system that is electrically
controlled and hydraulically actuated. The main landing gear is a
trailing-link design incorporating hydraulically actuated anti-skid brakes.
Landing gear extension/retraction is commanded by moving the landing
gear switch to the UP or the DN position. A ground safety function using
the left main gear WOW switch prevents landing gear switch movement
from the DN position to the UP position.
Main Landing Gear
Each main landing gear (MLG) strut attaches to the wing and retracts
inboard into the wing wheel well. Inboard and outboard gear doors
retract to cover the wheel well opening.
The MLG contains a trunnion, shock strut and trailing link, side brace
actuator, outboard door linkage rod, wheel and tire, brake assembly,
wheel-speed transducer, WOW switch, hydraulic brake tubes including
swivel joints, and an electrical harness. WOW signals are used by
various aircraft systems.
The MLG side-brace actuator has a downlock mechanism to hold the
landing gear in the down position. A downlock sensing device is
installed on the downlock mechanism. The gear is held in the up position
by the inboard door.
