25
To secure panels or doors on the aircraft require frequent removal
Purpose of Turn-lock fasteners
26
Types of turn lock fasteners
Camloc, Dzus, airlock, and camloc high stress fastener
27
Has four parts- stud assembly, grommet, receptacle, and retaining ring.
Camloc
28
Has three parts- stud, grommet, and stationary spring. Light duty- Used on box covers, access hole covers and light weight fairings. Heavy duty- Used on cowlings and heavy fairings, and has same construction features as light duty
Dzus
29
Has three parts- Stud, crosspin, and receptacle.
Airlock fastener
30
Has a higher strength, quick release rotating fastener that locks or unlocks by turning the stud a quarter turn.
Camloc high stress fasteners
31
How is size of screws and bolts determined
Diameter, length, and threads per inch
32
Used for the assembly of structural parts. Diameter is measured in sixteenths of an inch if a boat is larger than a quarter of an inch, it is normally sized by fraction
Sizing of screws and bolts
33
Insure the nut and bolt are the same diameter and have the same number of threads per inch
Bolt and screw installation/ removal
34
Used to measure outside diameter or thickness of parts Has a U shaped frame which comes in different sizes Attached to one end is a stationary measuring service called an anvil
Outside micrometer
35
Used to measure inside diameter, such as cylinders. | They are read the same as outside micrometers.
Inside micrometers
36
Used to measure depth of holes or grooves. Sleeve scale is numbered from top to bottom Leaves girl is numbered in the opposite direction of outside micrometers and read in reverse order
Depth micrometers
37
Force or turning effort required to apply attention to a fastener Measured in inch pounds foot pounds and newton meters
Torque
38
Should be half to five eights inch long and bent back and under to prevent it from becoming a safety hazard
Pigtail
39
.020, .032, and .040
Common sizes of safety wire
40
Most positive and satisfactory method
Lock wire/safety wire
41
Two styles of wiring
Double twist and single wire
42
Used to secure castellated nuts, pins, and shafts | Sizing is determined by length and diameter
Cotter pins
43
Consist of two layers of material sandwiching a low density area. The low density area gives the method it’s name.
Honeycomb
44
Consist of three or more layers of resin bonded fiberglass fabric
Solid laminate construction
45
Consist of precision laid strands of resin bonded fiberglass woven material. It’s appearance is similar to the weave on a spool of string.
Filament wound construction
46
How many general message of radome construction are there?
Four
47
Airworthiness of the aircraft could be seriously affected Safety of the aircrew could be seriously affected The enclosed antenna could be destroyed The function of the equipment could be lost or completion of the mission could be impacted
Grade A
48
Would not seriously affect airworthiness or personal safety | The antenna would not be destroyed nor would a loss of function or mission occur
Grade B
49
Solid wall radomes typically used for nose radomes and Doppler navigation radar or windows
Style A
50
Thin wall radomes typically use for electronically warfare antenna covers to save weight when size and frequency permit
Style B
51
Simple sandwich multi layer wall radomes commonly used to overcome the environmental limitations of Style A and B radomes
Style C
52
Complex multilayer wall radome
Style D
53
Three major causes of damage to radomes
Careless handling, in-flight damage, and window deterioration.
54
Fracture occurs when the radome is unable to withstand the impact of raindrops
Rain impact
55
Damage occurs on all radome surfaces exposed to direct impact of raindrops during flight
Rain erosion
56
More severe than rain damage in that the radome Surface is bombarded by a hard ice particles
Hail damage
57
Damage occurs infrequently and results in damage ranging from scorch coatings, delamination, or holes burned completely through the radome wall
Lightning strike
58
Is very rare, but is so devastating to a radome that it demands mention
Foreign object strike
59
Caused by fluid contamination, the use of unauthorized materials, or chemical breakdown caused by exposure to authorize the materials over a long period of time.
Window deterioration
60
Damage to the paint or coating
Class 1
61
Damage that is not deeper than a second ply of cloth or filament
Class 2
62
Damage to the outer skin only
Class 3
63
Damage consist of a home in the outer skin with damage to the core Damage may not exceed 1/2 the thickness of the wall Defined according to the construction style
Class 4
64
Defined according to the construction style
Class 5
65
Master stores to dielectric properties of the part, including skin thickness, pattern distortion, and transmission efficiency.
Step joint method
66
Is only used when specifically authorized by the applicable MIM
Scarf joint method
67
Are explosive when mixed
Epoxy and polyester catalyst
68
What are the 2 constituents of a composite material
Fibers and the matrix
69
Is extensional stiffness of the fibers that allow ______________to replace aluminum or steel as a structural material
Advanced composite materials
70
Has a higher strength to weight ratio the metallic materials The higher strength to weight ratio allows the lighter aircraft to carry payloads longer distances, with better fuel economy.
Advanced composite materials
71
What type of monitoring at a medical facility is required for all composite repair technicians
Respiratory monitoring
72
Preventative maintenance- Corrosion inspections, treatment, and protection systems Corrective maintenance- damage evaluation, classification, and determination if the damage is with in the authorize limits
O level is limited to
73
Corrosion inspections, treatment, and protection systems
preventative maintenance
74
Dammit evaluation, classification, and determination if the damage is within the authorize limits
Corrective maintenance
75
Three matrixes
Epoxy resins, Bismaleimide resins, and polyamide resins
76
Used to manufacture complex con toward parts
