STABILIZER ABRASION BOOT CARE

If the airplane is equipped with stabilizer abrasion boots, keep them
clean and free from oil and grease, which can swell the rubber. Wash
them with mild soap and water, using Form Tech AC cleaner or naphtha
to remove stubborn grease. Do not scrub the boots and be sure to wipe
off all solvent before it dries. Boots with loosened edges or small tears
must be repaired. Your Cessna Authorized Service Facility has the
proper material and knowledge how to do this correctly.

PROPELLER CARE

Always conduct a preflight inspection and occasionally wipe the blades
with a cloth dampened with oil to clean off grass and bug stains,
minimize corrosion, and assure a longer blade life. Waxing the blades
with an automotive type paste wax on a regular basis will further
minimize corrosion. Damaged or blistered paint must be repainted.
During the preflight inspection, check the blades for nicks, gouges,
scratches, corrosion pits, etc., the propeller hub for evidence of grease
and oil leaks, and the propeller spinner for condition and security.
Repair of small nicks and scratches may be performed by qualified
mechanics in accordance with procedures specified in FAA Advisory
Circular 43.13-1A. However, whenever a significant amount of metal is
removed, or in the case of previously reworked blades that may be at or
near minimum width and thickness limits, the appropriate Hartzell
Service Manual must be consulted to determine if minimum allowable
blade width and thickness limits have been exceeded. If these limits are
exceeded, blade replacement is required. After filing and polishing, the
damaged area must be inspected by the dye penetrant method to verify
that all damage has been removed and the blade is not cracked. The
area should then be reprotected by localized application of chemical
film per MIL-C-5541 (e.g., Alodine) and repainted as necessary. Large
nicks or scratches or other damage involving such things as bent
blades, balance, diameter reduction, etc. must be corrected by an FAA
approved propeller repair station.
