To
extend
and lock
the
gears
in the
event
of hydraulic failure,
it is
necessary
only
to
relieve the
hydraulic
pressure.
Emergency
gear
extension
must
not
be
attempted
at
airspeeds
in
excess
of 85
KIAS. An
emergency gear
extension
knob,
located
directly
beneath
the
gear
selector
switch is
provided
for
this
purpose
Pulling this knob
releases
the
hydraulic
pressure
holding
the
gear
in the
up
position
and
allows
the
gear
to
fall
free.
During
normal
operation,
this
knob is
covered
by
a
guard
to
prevent
inadvertent extension
of
the
gear.
Before
pulling the
emergency
gear
extension
knob, place
the
landing
gear
selector
switch
in
the
"DOWN"
position
to
prevent
the
pump
from
trying
to
raise
the
gear.
If
the
emergency
gear
knob
has
been
pulled
out
to
lower
the
gear
by
gravity,
due
to
a gear
system
malfunction,
leave
the
control
in its
extended
position
until
the
airplane
has been
put
on
jacks
to
check
the
proper
function
of
the
landing
gears
hydraulic and
electrical
systems.
See
Aircraft
Service
Manual
for
proper
landing
gear
system
check
out
procedures.
If
the
airplane
is
being used for training
purposes
or a
pilot
check
out
mission,
and
the
emergency gear
extension
has
been
pulled
out,
it
may
be
pushed
in
again
when
desired
if
there
has
not
been
any
apparent
malfunction
of
the
landing
gear
system.
