Flashcards in Aircraft Painting And Finishing Deck (28):
1

What are the two types of dope used for fabric finishes

Nitrate and butyrate

2

What finishing defect is the result of a paint room temperature that is too warm

Pinholes or blisters

3

What causes dope to blush and how can it be prevented

High humidity, moisture in the spray system, or application over a damp surface can be eliminated by heating the room to decrease humidity or by using a blush retarding thinner to increase the drying time

4

What factor cause spray paint sags and runs

Poor surface preparation or paint sprayed on too thickly

5

What components or parts of the airframe must be protected from damage when using paint stripper/ remover

Windshields and windows, plastics, composites, synthetic rubber, and fabrics

6

What is the function of zinc-chromate primer

Prevent corrosion and provide a good bond between the metal and the topcoats

7

Name several common types of paint used on aircraft

Zinc-chromate and wash primers, synthetic enamels, acrylic lacquer, and polyurethane

8

What health and safety precaution must be observed when used the toxic solvents and thinners that are part of modern finishing systems

Respirators and mask must be worn when spraying finishes

9

What causes orange peel

Incorrect spray setting, incorrect air pressure, incorrect paint viscosity, and holding the gun too far from work

10

What regulation governs the application of the registration number to aircraft registered in USA

FAR Part 45

11

Other than appearance what is another reason for touching up painted surfaces

Reduce or eliminate corrosion problems

12

What reference should be used to determine if a control surface must be checked or rebalanced after

The manufactures service manual

13

What are the three most commonly used method of applying paint

Dipping, brushing, and spraying

14

What is the effect on paint finishes if too much drier is added to the paint

The paint film will be brittle and tend to crack and peel

15

What paint system may be used with epoxy topcoats

Any paint system in good condition

16

Where are the registration marks required to be placed on a fixed wing aircraft

On a vertical tail surface or on the side of the fuselage

17

What is the generally required dimensions of the registration numbers on the side of a fixed wing aircraft

12 inches and 2/3rds wide as they are high. They must be solid letters and spacing no less than a quarter inch apart

18

Does a rejuvenator restore strength to the fabric

No,it only restores resilience to the finish

19

What causes pinholes in a finish

Excessive atomizing air on the spray gun

20

What safety precaution must be observed when sweeping a paint room that has dried dope or lacquer overspray on the floor

The floor must be wet down with water before it is swept. Static electricity from dry sweeping can cause a fire

21

Why is butyrate dope safer to use than nitrate dope

It is much less flammable

22

What is the purpose in using fungalsidal dope when finishing aircraft fabric

To keep fabric from rooting

23

What are the three types of dope used for aircraft finishes

Clear dope , semi- pignitive dope, and pigmentive dope

24

What would happen if dope was used over paint or enamel

It would have the tendency to lift and remove the paint or enamel

25

What is used to thin zinc chromate primer

Toluene

26

Which federal regulation prescribes the size and location requirements for aircraft identification numbers

FAR Part 45

27

What is the appearance of a blushing paint finish

Chalky or cloudy

28

What causes blushing in a dope finish

Too high humidity
