CIIEROKEE WARRIOR
In
jacking
the airplane
for landing
gear
or other service, two hydraulic
jacks
and
a tail stand
should
be
used. At least 250
pounds
of ballast should be
placed
on
the tailstand before
jacking
the airplane. The hydraulic
jacks
are
placed
under the
jack
points
on the
underside
of the wings,
and the
airplane
is
jacked
up until the tail stand can be attached to the tail
skid. After
attaching
the
tail
stand and adding
the
ballast,
the
jacking
can
be continued until the airplane
is at the
desired heieht.
The steering arrns
from
the rudder
pedals
to the nose
gear
are
adjusted at the rudder
pedals
or at the nose
wheel
by turning in or out the tlrreaded rod
end bearings.
Adjustments are
normally made at the forward end of the rods and should be
done in such a
way
that the
nose
wheel is in line with the fore and aft axis of the airplane
when the
rudder
pedals
and rudder are
centered. Alignment of
the nose wheel
can
be
checked
by
pushing
the airplane
back and
forth
with the rudder
centered
to determine that the
plane
follows
a
perfectly
straight line.
The turning arc of the
nose wheel is
30 degrees
either
side
of center and is
factory adjusted
at stops
on the bottom
of
the
forging. The turning radius of the
nose wheel is
l3
feet.
The rudder bar stops should be
carefully adjusted so that
the rudder
bar
reaches
its full
traveljust
after the rudder
hits
its stops.
This
guarantees
that the rudder
will be allowed
to move
through
its full
travel.
PROPELLER
SERVICE
The
spinner
and backing
plate
should be cleaned and
inspected
for
cracks
frequently.
Before each flight the
propeller
should be
inspected for nicks, scratches,
or corrosion.
If found,
they should be repaired as soon as
pssible
by a rated mechanic, since
a nick or scratch
causes
an
area of increased
stress which
can
lead to
serious
cracks or the
loss of a
propeller
tip.
The back
face
of the blades
should
be
painted
when necessary
with flat black
paint
to
retard
glare.
To
prevent
corrosion, all zurfaces
should be cleaned
and waxed
periodically.
