EMERGENCY LANDING GEAR EXTENSION
In the event the landing gear fails to extend normally, slowling the airplane
below 97 kt (180 km/h) and placing the landing gear lever in the down
position should allow the landing gear to ”free fall” to the down and locked
position, as evidenced by the green gear down lights illuminating. Following
this procedure, should the gear lights indicate that the gear is still not down
and locked, utilize the emergency landing gear control under the L.H. panel
strip to extend the gear.
For this, push on central knob before pulling the lever rearward. For complete
procedures, refer to Section 3 ”
”.
The emergency landing gear control cannot be used to retract the gear,
however, it is necessary to push back this control to retract the landing gear in
a normal way.
LANDING GEAR WARNING SYSTEM
The airplane is equipped with a landing gear warning system designed to
help prevent the pilot from inadvertently making a wheels–up landing. The
system consists of a throttle–actuated microswitch which is electrically
connected to an aural warning unit.
In gear up configuration, when throttle is retarded at approximately
½
inch
(12 mm) of the aft stop (battery switch–breaker ON), the throttle linkage will
actuate on a microswitch which is electrically connected to the gear aural
warning unit.
If the landing gear is retracted (or not down and locked), a continuous tone
will be heard on the alarm loud–speaker. In addition, a microswitch
connected to the wing flap system also sounds a tone when the flaps are
extended beyond 10
°
with the landing gear retracted.
A ”LDG PUMP” amber warning light (if installed) located at advisory panel
L.H. side, illuminates to indicate operation of the hydraulic generator.
