2.26 Upholstery and interior
Keeping the upholstery and interior clean prolongs upholstery fabric and interior trim life. To clean
the interior, proceed as follows:
a. Brush or vacuum clean the upholstery and carpet to remove dust and dirt.
b. Clean upholstery with a sponge moistened with fresh water
c. Wipe plastic trim with a damp cloth.
d. Oil spots and stains may be cleaned using household spot removers, sparingly. Before using any
solvent, read the instructions on the container and test it on an obscure place in the fabric to be
cleaned. Never saturate the fabric with volatile solvent; it may damage the padding and backing
material. Scrape sticky material from the fabric with a dull knife, then spot clean the area.
2.27 Propeller
Wash hub and blades with a soft cloth and water (and with a mild detergent if necessary), then
dry thoroughly.
2.28 Wheels
The wheels should be washed periodically and examined for corrosion, cracks and dents in the
wheel halves or hubs. If defects are found, remove and repair in accordance with Section 5. Discard
cracked wheel hubs and install new parts.
2.29 Lubrication
The A240 has been designed to have as few lubrication points as possible. For areas that do require
lubrication, regular grease should be used. The following list details the areas that will require occasional
lubrication.
a. wing main bolts
b. wing folding mechanism hinge
c. wing flap push-pull rods connection and hinges
d. stabilizer mounting bolts
e. all control surface hinges in general
f. undercarriage bearing and movable holder
Caution
Particular care should be given to electrical equipment before cleaning. Solvent
should not be allowed to enter magnetos, starter, alternator, voltage regulator and
the like. Hence, these components should be protected before saturating the engine
with solvent. Any fuel, oil and air openings should be covered before washing the
engine with solvent. Caustic cleaning solutions should not be used. After cleaning
engine re-lubricate all control arms and moving parts.
Caution
Do not use gasoline, alcohol, benzene, acetone, or laquer thinner. These solvents
will soften and damage the propeller finish.
Caution
Do not lubricate pulleys and bushings of control surface cables and rods. When
changing wheels it is recommended to lubricate wheel axles before reassembling to
prevent them from corrosion and keep wheel changing easier.
