ATO CORROSION EXAM QUESTIONS AND
ACCURATE ANSWERS
What is the main purpose of the Paint System? - ANSWER To protect all exposed
surfaces against corrosion and any other forms of deterioration.
What are the Operational Uses for the Paint System? - ANSWER Glare Reduction by flat
coating
Special finishes for reduction of heat absorption
Camouflage and other detection countermeasures
High visibility requirements
Identification markings
What are the tools that apply Paint coating? - ANSWER Brushes
Touch-Up pens
Rollers
Spray Guns
What shall not be done to Natural and Synthetic Rubber? - ANSWER Shall not be Painted
or oiled
To what is Rubber susceptible? - ANSWER Fungus Growth, which can bring about
deterioration of the rubber and corrosion of surrounding metal surfaces.
What shall not be done to depleted Uranium? - ANSWER Abrade or sand
The Environmental Protection Agency (EPA) has set special requirements for using this
, process to be utilized on aircraft surfaces - ANSWER Spray Painting
If the protective finish covering the depleted Uranium is chipped, peeled or otherwise
removed and the dark gray or black depleted Uranium can be seen what should be
done? - ANSWER The part should be returned to the licensee for rework or disposal.
Preferred alternatives for touch-up painting since they produce little paint waste and do
not require solvent clean up. - ANSWER Brush and Rollers
The three general equipment areas that are COMMONLY affected by corrosion are? -
ANSWER Bilge Area
Equipment Bay Area
Engine Compartment
This areas contain all types of avionic equipment and offer numerous locations for the
following to collect: dust, water Hydraulic fluid, metal shavings, trash, loose hardware,
other debris. - ANSWER Bilge Area
Highly prone to corrosion. This is particularly true in rotorcraft and those aircraft
utilizing outside ram air cooling. This area should be periodically inspected by
technicians. - ANSWER Avionics Equipment Bay
Area containing hardware, electrical connectors, terminal boards, junction boxes and
ram air turbine which should be inspected for signs of salt spray contamination and
corrosion. - ANSWER Engine Compartment
Must be removed to facilitate inspection. They are usually the last items to. be inspected
for corrosion damage. - ANSWER Shock Mounts
Two types of batteries found on avionic equipment are? - ANSWER Lead acid
Nickel- Cadmium
