When
parking the airplane,
head
into the wind
and
set
the parking

In

as
outlined
in
the
following
paragraph.
TIE-DOWN
Proper tie-down procedure
is the
best
precaution against
damage
to
the parked airplane by gusty
or strong
winds. To tie-down the airplane
securely,
proceed
as
follows:
1.
Set
the parking brake
and
install
the control wheel lock.
2.
Install
a
surface control lock over the
fin
and rudder.
3. Tie sufficiently strong
ropes
or
chains
(700 pounds tensile
strength)
to
the wing,
tail,
and nose
tie-down
fittings
and secure
each
rope or chain to
a
ramp tie-down.
4.
Install
a
pitot
tube
cover.
JACKING
When
a
requirement
exists
to
jackthe entire airplane
off the
ground,
or
when
wing jack points
are used
in
the jacking operation, refer to the
Service Manual
for
specific procedures
and
equipment required.
Individual main
gear may
be
jacked by using the jack
pad
which is
incorporated in
the
main landing gear strut
step
bracket.
When
using
the
individual
gear strut jack
pad,
flexibility
of
the gear strut
will
cause
the
main
wheel to
slide inboard
as
the
wheel is raised,
tilting
the
j
ack.
The
j
ack
must
then
be
lowered
for
a
second
jacking operation.
Do
not
jack
both
main
wheels simultaneously using the
individual main
gear
jack
pads.
If
nose
gear
maintenance
is
required,
the nose
wheel
may
be
raised
off
the ground by pressing down on
a
tailcone bulkhead, just forward
of
the
horizontal stabilizer,
and
allowing
the
tail
to 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.
