The wing flap
system
circuit is
protected
by
a l5-ampere
circuit
breaker,
labeled FLAP,
on
the left side of the switch
and
control
panel.
A
gear
warning
interconnect switch
is
incorporated
in the flap system,
and sounds a warning
horn when
the
flaps are
extended beyond 25o
with
the
landing
gear
retract€d.
LANDING
GEAR
SYSTEM
The landing
gear
is a retractable, tricycle type
with a
steerable
nose
wheel
and
two
main
wheels.
Shock
absorption is
provided
by the
tubular
spring-steel mainlanding
gear
struts andthe
airloilnose
gear
shock
strut.
Each main
gear
wheel is equipped
with
a
hydraulically actuated disc-type
brake on the
inboard side ofeach
wheel.
The
landing
gear
extension, retraction, and main
gear
down
lock
operation
,is
accomplished
by hydraulic actuators
powered
by
an
electrically-driven
hydraulic
porrer pack (see
figureT-7). Ttre
power
pack
is located aft of the
firewall between the
pilot's
and
copilot's rudder
pedals.
The hydraulic system
fluid
level
may be checked by
utilizing the
dip-
stick/-filler cap
located on the top right side of
the
power pack
adjacent
to
the motor mounting
flange. The
system
should be checked at
25-hour
intervals, and anytime
a hydraulic failure
in
the system requires the
use of
the emergency
hand
pump
to
extend
the landing
gear.
If the fluid level
is at
or below
the ADD
line
on
the dipstick; hydraulic
fluid
(MIL-H-5606)
should
be added to maintain
the
level
to
the top of the dipstick'/ filler cap opening.
A
normal
operating
pressure
of
1000 PSI to
1500 PSI is
automatically
rnaintained
in
the
landing
gear
system,
and is sufficient
to
provide
a
positive
up
lock
pressure
on the main Iauding
gear.
The nose
gear
incorporates an over-center
mechanical
linka$e which
provides
a
positive
mechanical up and down
lock. Mechanically-actuated
whedl well
doors
are
provided
for the
nose
gear.
The doors open
whe:n the
nose
gear
extends,
and close when
it retracts.
Power
pack
operation
is
started
and stopped by
a
p.'essure
switch,
and
hydraulic
pressufe
is directed by
the landing
gear
lel'er. T\uo
position
indicator lights
are
provided
to
show
landing
gear position.
The
landing
gear
system
is also eluipped
with a nose
gear
safety
(squat)
switch,
an
emergency extension
hand
pump,
and a
gear-up
warning system.
