rest
on
the
tail
tie-down
ring.
NOTE
Do
not
apply
pressure
on
the
elevator
or
outboard
stabiliz-
er
surfaces.
When
pushing
on
the
tailcone,
always
apply
pressure
at
a
bulkhead
to
avoid
buckling
the
skin.
To
assist
in•raising
and
holding
the
nose
wheel
off
the
ground,
weight
down
the
tail
by
placing
sand-bags,
or
suitable
weight,
on
each
side
of
the
horizontal
stabilizer,
next
to
the
fuselage.
If
ground
anchors
are
available,
the
tail
should
be
securely
tied
down.
NOTE
Ensure
that
the
nose
will
be
held
off
the
ground
under
all
conditions
by
means
of
suitable

under
weight
supporting
bulkheads
near

LEVELING
Longitudinal
leveling
of
the
airplane
is
accomplished
by
placing
a
level
on
leveling
screws
located
at
stations
94.63
and
132.94
on

to
properly
center
the
bubble
in
the
level.
Corresponding
points
on
both
upper
door

may
be
used
to
level
the
airplane
laterally.
FLYABLE STORAGE
Airplanes
placed
in
non-operational
storage
for
a
maximum
of
30
days
or
those
which
receive
only
intermittent
operational
use
for
the
first
25
hours
are
considered
in
flyable
storage
status.
Every
seventh
day
during
these
periods,
the
propeller
should
be
rotated
by
hand
through
five
revolutions.
This
action
"limbers"
the
oil
and
prevents
any
accumulation
of
corrosion
on
engine
cylinder
walls.
I
WARNING
I
For
maximum
safety,
check
that
the
ignition
switch
is
OFF,
the
throttle
is
closed,
the
mixture
control
is
in
the
idle
cut-off
position,
and
the
airplane
is
secured
before
rotating
the
propeller
by
hand.
Do
not
stand
within
the
arc
of
the
propeller
blades
while
turning
the
propeller.
After
30
days,
the
airplane
should
be
flown
for
30
minutes
or
a
ground
runup
should
be
made
just
long
enough
to
produce
an
oil
temperature
within
the
lower
green
arc
range.
Excessive
ground
runup
should
be
avoided.
