AIRPLANE CLEANING AND CARE
PAINTED SURFACES
The painted exterior surfaces of your new airplane require an initial
curing period which may be as long as 90 days after the finish ;s applied.
During this curing period some precautions should be taken to avoid damag-
___ ing the finish or interfering with the curing process. The finish should
be cleaned only by washing with clean water and mild soap, followed by a
rinse water and drying with cloths or a chamois. Do not use polish or wax,
which would exclude air from the surface, during this gO-day curing period.
Do not rub or buff the finish and avoid flying through rain, hail or sleet.
To hel p prevent development of carras; on, pa rti eula rl y fil ifonn corro-
sion, the airplane should be spray washed at least every two or three weeks
(especially in warm, damp and salty environments), and waxed with a good
grade of water repellent wax to help keep water from accumulating in skin
joints and around countersinks. A heavier coating of wax on the leading
edges of the wing and tail (on airplanes without deice boots) and On the
engine nose cap and propeller spinner, will help reduce abrasions encoun-
tered in these areas.
PROPELLER
Pref1 ight inspection of propeller blades for nicks and wiping them
occasionally with an oily cloth to clean off grass and bug stains will
assure long, trouble-free service. It is vital that small nicks on the
propeller, particularly near the tips and on the leading edges, are dressed
out as soon as possible since these nicks produce stress concentrations,
and if ignored, may result in cracks. Never use an alkaline cleaner on the
blades; remove grease and dirt with Stoddard solvent.
LANDING GEAR
Cessna Dealer's mechanics have been trained in the proper adjustment
and rigging procedures of the landing gear system. To assure trouble-free
gear operation, have your Cessna Dealer check the gear regularly and make
any necessary adjustments. Only properly trained mechanics should attempt
to repair or adjust the landing gear components and system.
DEICE BOOTS
The optional deice boots have a special, electrically conductive coat-
ing to bleed-off static charges which cause radio interference and may
perforate the boots. Fueling and other servicing operations should be done
carefully, to avoid damaging this conductive coating or tearing the boots.
To prolong the life of surface and propeller deice boots, they should
be washed and serviced on a regular basis. Keep the boots clean and free
from oil, grease and other sol vents which cause rubber to swell and deteri-
orate. Outlined below are recommended cleaning and servicing procedures.
r------f(iC:AA:U'UTnlooN'\N!------..
Use only the following instructions when cleaning
boots. Disregard instructions which recommend
petroleum base liquids (Methyl-Ethyl-Ketone, non-
leaded
gasoline, etc.) which can ham! the boot
material.
