THRUSH AIRCRAFT, INC – MODEL S2RHG-T65 TURBO THRUSH
A. Wash all exterior surfaces of the aircraft with plain water and any commercial
soap or detergent. Soap and detergent are organic chemicals, and it is important
that all traces be removed by flushing with plain water.
B. Detach all removable panels from the aircraft. Wash down the rear fuselage aft
of the wing trailing edge. Tube joints, skin bends, and so forth should receive
particular attention. Remove excess moisture after flushing.
C. The forward fuselage and engine section should not be cleaned with water
unless close attention is made to avoid removal of lubricants and to avoid
possible rusting of components and hardware. A general purpose, non-corrosive
cleaning agent is preferred in those areas.
D. Particular attention should be given to the wing center splice fittings and the
attachments of the oil cooler, hopper and engine mount.
E. Hopper cleaning should be accomplished at the end of each working day. A
good commercial detergent should be used and followed by a thorough flush with
water. Leave the hopper door and gate open for thorough drying.
An anti-static type of plastic cleaner, such as Mirror Glaze or equivalent, is recommended
for best cleaning. The side windshields are plastic and should not be cleaned with
gasoline, alcohol, acetone, and lacquer thinner, or window cleaning spray. Those fluids
will soften the plastic and cause crazing. Avoid rubbing the plastic surface with a dry
cloth, as that can cause scratches and build up an electrical charge (static) which will
attract dust particles. If scratches are visible after removing the dust accumulation, finish
the plastic with a quality grade of commercial wax. Apply the wax in a thin, even coat and
carefully buff out with a soft cloth. Do not buff or polish in one area for more than a brief
period of time. The heat generated by rubbing the surface may soften the plastic and
may produce visual distortion.
The middle section of the windshield is safety plate glass for better resistance to
scratching. It is enclosed in an aluminum frame.
Hopper repair may be accomplished in accordance with the instructions contained in
Section 9.
Fuel tank repair may be accomplished in accordance with the instructions contained in
Section 5.
The 24-volt batteries are installed in the engine compartment between the engine and
firewall. Access is gained to the batteries by removal of a cowling. Battery servicing
involves adding distilled water to maintain electrolyte level of 3/16 inch over the
separators, checking the cable connections, and neutralizing or cleaning any spilled
electrolyte or any corrosion. Use bicarbonate of soda and clean water to neutralize
corrosion. Follow with a thorough flushing of clean water and wipe dry. Clean the cable
