Question 1

three classification of damage

Answer 1

negligible, repairable, non-repairable

Question 2

is damaged that may be corrected by a simple procedure with no restrictions on flight operations

Answer 2

negligible

Question 3

is damaged to the skin, bond, or core that places restrictions on the aircraft or part

Answer 3

repairable

Question 4

is damaged beyond established repair limits

Answer 4

non-repairable

Question 5

defect on the outer surface that does not involve damage to the structural reinforcing fibers

Answer 5

cosmetic defects

Question 6

often caused by chipping or scratching during handling

Answer 6

cosmetic defects

Question 7

occurs when foreign object strike the part

Answer 7

impact damage

Question 8

is a defect on the outer surface that does not involve damage to the structural reinforcing fibers

Answer 8

impact damage

Question 9

most common cause of impact damage

Answer 9

careless handling during transportation or storage, or standing parts on their edge without adequate protection

Question 10

is a separation of fabric layers of a material in a laminate

Answer 10

delamination

Question 11

delamination occurs as a result of several causes like?

Answer 11

impact, moisture in the fabric, lightning strikes

Question 12

another type of delamination

Answer 12

unbond or disbond

Question 13

occurs when the skin of the sandwich structure becomes separated from the core

Answer 13

disbond / unbond

Question 14

can occur in advanced composite structures just as in metallic ones

Answer 14

cracks

Question 15

may occur from impact damage, over-torquing fasteners, or as a result of fastener pull-through. holes filled in the wrong location, wrong size, wrong number of holes can also be classified as this.

Answer 15

hole damage

Question 16

are not easily detected however, they could lead to extensive damage

Answer 16

tiny holes

Question 17

types of damage

Answer 17

cosmetic defects, impact damage, delamination, cracks, hole damage

Question 18

used to detect cracks, surface irregularities, and surface defects such as delamination and blistering

Answer 18

visual inspections

Question 19

one of the most important tools used to detect internal flaws or delamination

Answer 19

coin tap test

Question 20

uses a high frequency sound wave as a means of detecting flaws in a part by beaming a high frequency wave response, delamination, flaws, or other condition are detected

Answer 20

ultrasonic inspections

Question 21

is time versus amplitude display read from left to right

Answer 21

a-scan

Question 22

takes a cross-sectional view of the material being tested and used as an oscilloscope screen to compare the sample

Answer 22

b-scan

Question 23

imaging shows the shape, size, and location of the damage, but does not show the depth

Answer 23

c-scan

Question 24

locates flaws by temperature variations at the surface of a damaged part. heat is applied to the part then the temperature gradients are measured using an infrared camera or film

Answer 24

thermography

Question 25

it calls for the suspected part to be heated and then photographed using a laser light source and a special infrared camera film system

Answer 25

laser holography

Question 26

used to detect disbands or water in honeycomb and impact damage

Answer 26

laser holography

Question 27

used to detect cracks that cannot be visually detected, both internally and externally

Answer 27

radiography

Question 28

useful in detecting the extent of the damage that cannot be visually detected

Answer 28

radiography

Question 29

used to determine whether the resins have reached their proper strength such as the barcol tester

Answer 29

hardness testing

Question 30

used successfully for detecting cracks in metallic surfaces, however, it should not be used with advance composite because if it is allowed to sit on the surface, the wicking action of the fibers may take the dye penetrant and would no longer bond the new material

Answer 30

dye-penetrant

Question 31

types of inspections

Answer 31

visual inspection, coin tap test, ultrasonic inspection, thermography, laser holography, radiography, hardness testing, dye-penetrant

Question 32

a superficial, non-structural filler is used to restore a surface to keep fluids out until a more permanent repair is made

Answer 32

cosmetic repair

Question 33

this type of repair will not regain any strength and is used only where strength is unimportant.

Answer 33

cosmetic repair

Question 34

this type of repair can be effective in limited instances, where the delamination is restricted to one ply.

Answer 34

resin injection

Question 35

quick and cheap repair

Answer 35

resin injection

Question 36

this type of repair can hope to slow the spread of delamination and is generally considered a temporary measure

Answer 36

resin injection

Question 37

this type of repair can gain some strength

Answer 37

semi-structural plug/patch

Question 38

mechanically-fastened plug and patch repair can be especially effective where thick solid laminated are used, since they take the bolt loads well

Answer 38

semi-structural plug/patch

Question 39

Full structural repairs using bolted doublers can be used in heavily loaded solid laminates. This is often the only practical means of repairing such structures.

Answer 39

structural mechanically-fastened doubler

Question 40

often used to perform repairs to lightly loaded thin laminate structures

Answer 40

structural bonded external doubler

Question 41

this type of repair is especially common using wet lay-up materials

Answer 41

structural bonded external doubler

Question 42

This repair restores full structural properties by forming a joint between the prepared repair area and the repair patch

Answer 42

structural flush repair

Question 43

made by replacing each ply of the composite laminate that has been removed from the damage area

Answer 43

structural flush repair

Question 44

types of repair

Answer 44

cosmetic repair, resin injection, semi-structural plug/patch, structural mechanically-fastened doubler, structural bonded external doubler, structural flush repair
