HANDLING, SERVICE & MAINTENANCE
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.
When a requirement exists
to
jack the entire airplane
off
the
ground, or
when wing jack points are used
in the jacking operation,
refer
to
the Maintenance 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
rwill cause the main wheel
to
slide inboard as the wheel is
raised,
tilting the jack. The jack must then
be
lowered
for a second jacking
operation. Do
not
jack both main wheels simultaneously using
the
individual
main gear
jack
pads.
DO NOT APPLY PRESSURE ON
THE ELEVATOR
OR HORIZONTAL STABILIZER SURFACES.
WHEN PUSHING
ON
THE
TAILCONE, ALWAYS
APPLY PRESSURE AT A
BULKHEAD TO AVOID
BUCKLING THE SKIN.
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.
