- Landing gear
The airplane is equipped with electro-hydraulically actuated, fully retractable tricycle
landing gear.
Each landing gear is equipped with one wheel and an oil-air shock absorber
integrated in the strut.
Main landing gears
swivel on two ball joints installed on wing spars. Each landing
gear retracts toward airplane centerline. The operation is accomplished by a hydraulic
actuating cylinder which also provides up and down locking.
Nose gear
swivels on two ball joints installed on a tubular steel mount frame. Its
operation is accomplished by a hydraulic actuating cylinder which also provides up
and down locking. The nose wheel is steerable. It is connected to pedals through a
spring rod and is provided with a shimmy damper. In UP position, nose wheel is
automatically disconnected.
Actuating cylinders
have a locking device integrated at both ends. This device
maintains landing gear in up or down position.
Landing gear doors
, two on the nose gear, two on each main landing gear, are driven
and kept in UP position by the landing gear itself.
All doors are mechanically kept in down position.
Hydraulic pressure
Hydraulic pressure
required for landing gear operation is provided :
-
during normal operation, by an electro-hydraulic generator with integrated
reservoir,
-
during emergency extension operation by a hand pump supplied with an
auxiliary reservoir.
Landing gear lever
- see figure 7.5.1
LANDING GEAR lever, located on LANDING GEAR panel at the bottom of instrument
panel left part, is accomplished by an electric selector actuated through a lever ending
with a knob representing a wheel. Operation is carried out by pulling on lever and by
putting it in the desired UP (retracted) or DN (extended) position. This selector controls
hydraulic generator.
