(5) Tie a sufficiently strong rope or chain (700 pounds tensile strength)
to the tie-down ring on each boom and secure each rope to a common
ramp tie-down.
NOTE
In areas where heavy snow accumulations occur,
additional precautions should be taken when storing
the airplane outside. A heavy accumulation of snow
on
the stabilizer can cause the tail section to rotate
downward, resulting in damage to the fins. Proper
nose gear tie-down and a simple tail support attached
to one of the boom tie-down rings will protect against
such damage.
(6) Install a pUot tube cover.
WINDSHIELD- WINDOWS.
The plastic windshield and windows should be cleaned with an aircraft
windshield cleaner. Apply the cleaner sparingly with soft cloths, and rub
with moderate pressure until all dirt, oil scum and bug stains are removed.
Allow the cleaner to dry, then wipe it off with soft flannel cloths.
If a windshield cleaner is not available, the plastic can be cleaned with
soft
cloths moistened with Stoddard solvent to remove oil and grease.
NOTE
Never use gasoline, benzine, alcohol, acetone, carbon
tetrachloride, fire extinguisher or anti-ice flUid, lacquer
thinner or glass cleaner to clean the plastic. These ma-
terials will attack the plastic and may cause it to craze.
Follow by carefully washing with a mild detergent and plenty of water.
Rinse thoroughly, then dry with a clean moist chamois. Do not rub the
plastic with a dry cloth since this builds up an electrostatic charge which
attracts dust. Waxing with a good commercial wax will finish the clean-
ing job. A thin, even coat of wax, polished out by hand with clean soft flan-
nel cloths, will fill in minor scratches and help prevent further scratching.
Do not use a canvas cover on the windshield unless freezing rain or
sleet is anticipated since the cover may scratch the plastic surface.
PAINTED SURFACES.
The painted exterior surfaces of your new Cessna have a durable,
long lasting finish and, under normal conditions, require no polishing or
buffing. Approximately 15 days are required for the paint to cure com-
pletely; in most cases, the curing period will have been completed prior
to delivery of the airplane. In the event that polishing or buffing is re-
quired within the curing period, it is recommended that the work be done
by
someone experienced in handling uncured paint. Any Cessna Dealer
can accomplish this work.
Generally, the painted surfaces can be kept bright by washing with
water and mild soap, followed by a rinse with water and drying with cloths
or a chamois. Harsh or abrasive soaps or detergents which cause cor-
rosion or make scratches should never be used. Remove stubborn oil
and grease with a cloth moistened with Stoddard solvent.
Waxing is unnecessary to keep the painted surfaces bright. However,
if desired, the airplane may be waxed with a good automotive wax. A
heavier coating of wax on the leading edges of the wings and tail and on
the engine nose cap and propeller spinner will help reduce the abrasion
encountered in these areas.
When the airplane is parked outside in cold climates and it is neces-
sary to remove ice before flight, care should be taken to protect the paint-
ed surfaces during ice removal with chemical liquids. A 50-50 solution of
isopropyl alcohol and water will satisfactorily remove ice accumulations
without damaging the paint. A solution with more than 50% alcohol is
harmful and should be avoided. While applying the de-icing solution, keep
it away from the windshield and cabin windows since the alcohol will at-
tack the plastic and may cause it to craze.
PROPELLER CARE.
Preflight inspection of propeller blades for nicks, and wiping them
occasionally with an oily cloth to clean off grass and bug stains will as-
sure long, trouble-free service. Small nicks on the propellers, particu-
larly near the tips and on the leading edges, should be dressed out as soon
as possible since these nicks produce stress concentrations, and if ig-
nored, may result in cracks. Never use an alkaline cleaner on the blades;
remOve grease and dirt with carbon tetrachloride or Stoddard solvent.
