MODEL 560 OPERATING INFORMATION
AIRPLANE CLEANING AND CARE
PAINTED SURFACES
The exterior of a new airplane is painted with a polyurethane two-component topcoat which, unlike
early coatings, does not require exposure to air for complete cure to occur. The care required by the finish
will not change as the paint ages.
The finish should be cleaned only by washing with clean water and mild soap, followed by rinse water
and drying with a soft cloth or chamois.
Minimize flying through rain, hail or sleet.
To help prevent development of corrosion, particularly filiform corrosion, 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 edge, on the vertical tail and on the engine nose
cones helps to reduce abrasions encountered in these areas.
Polyurethane topcoats are designed with UV inhibitors to slow the degradation caused by exposure.
The inhibitors concentrate near the surface of the coating during the initial stages of cure. Care must be
taken during any buffing, polishing, or power waxing so that this surface layer is disturbed only to the
smallest extent necessary. With special care, however, buffing, polishing or power waxing is acceptable.
Wax products containing silicones should be avoided as they contribute to the buildup of P-static, especially
if the surface is well buffed to produce a shine.
DEICE BOOTS
The deice boots on the horizontal stabilizer leading edges have a special electrically conductive
coating 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 deice boots, they should be washed and serviced on a regular basis.
Keep the boots clean and free from oil, grease and other solvents which cause rubber to swell and
deteriorate. Outlined below are recommended cleaning and servicing procedures.
CAUTION
USE ONLY THE FOLLOWING INSTRUCTIONS WHEN CLEANING BOOTS.
DISREGARD INSTRUCTIONS WHICH RECOMMEND PETROLEUM BASE LIQUIDS
(METHYL-ETHYL-KETONE, NONLEADED GASOLINE, ETC.) WHICH CAN HARM
THE BOOT MATERIAL.
Clean the boots with mild soap and water, then rinse thoroughly with clean water.
NOTE
Isopropyl alcohol can be used to remove grime which cannot be removed using soap.
If isopropyl alcohol is used for cleaning, wash area with mild soap and water, then
rinse thoroughly with clean water.
To possibly improve the service life of deice boots and to reduce the adhesion of ice, it is
recommended that the deice boots be treated with AGE MASTER Number 1 and ICEX.
AGE MASTER Number 1, used to protect the rubber against deterioration from ozone, sunlight,
weathering, oxidation and pollution, and ICEX, used to help retard ice adhesion and for keeping deice boots
looking new longer, are both products of and recommended by B.F. Goodrich.
