Q

were available in two styles, hollow shank pull-through and self-plugging types. Used for repairing light aircraft.

A

FRICTION-LOCK RIVETS

29
Q

Designed to prevent the center stem of a rivet from falling out as a result of the vibration. Permanently locks the stem into place and vibration cannot shake it loose.

A

MECHANICAL-LOCK RIVETS

30
Q

Used as structural replacements for solid shank rivets.

A

HUCK-LOCKS

31
Q

Center stem is locked into place with a lock ring. High shear and bearing strengths.

A

CHERRYLOCKS

32
Q

Ring slips down the stem and locks the center stem to the outer shell.

A

OLYMPIC LOCKS

33
Q

Economical to use and strong enough to replace solid shank rivets, size for size.

A

CHERRYMAX

34
Q

RIVETS Used by aerospace industry

A

HI-SHEAR RIVETS

35
Q

Uses either a rivet gun or squeeze riveter

A

HAND RIVETING

36
Q

When there are a large number of easily accessible rivets to be installed, a compression, or squeeze riveter can be used.

A

COMPRESSION RIVETING

37
Q

Drives most rivets used in aircraft construction.

A

GUN RIVETING

38
Q

Has a pulling stem on which a pneumatic installation gun fits.

A

PULL-TYPE LOCKBOLT

39
Q

Placed into a blind hole and an installation gun is placed over the pulling stem.

A

BLIND-TYPE LOCKBOLT

40
Q

Installed in places where there is not enough room to use the standard pulling tool.

A

STUMP-TYPE LOCKBOLTS

41
Q

Straight shank with standard threads. To install a Hi-Lok, the hole is first drilled with an interference fit.

A

HI-LOKS

42
Q

Similar to the Hi-Lok except it is made from lighter materials and has a shorter transition from the threaded section to the shank.

A

HI-LITES

43
Q

Combines two titanium alloys which are bonded together to form a strong structural fastener.

A

CHERRYBUCKS

44
Q

Strongest special fastener used in aircraft construction.

A

TAPER-LOK

45
Q

High-strength structural fasteners used in close-tolerance holes where strength requirements are high.

A

JO-BOLTS

46
Q

are usually installed in interference fit holes. Use clearance fit holes if one or more of the structural members to be attached are made of steel, stainless steel, and titanium.

A

PIN FASTENERS

47
Q

All nuts must have some sort of locking device to prevent them from loosening and falling off. Many nuts are held on a bolt by passing a ______ ______ through a hole in the bolt shank and through slots.

A

COTTER PIN

48
Q

Locks onto a bolt on its own

A

SELF-LOCKING

49
Q

Relies on either a cotter pin, check nut, or lock washer to hold it in place.

A

NON- SELF LOCKING

50
Q

Uses a single piece of wire that passes through the hole in the turnbuckle’s center

A

SINGLE WRAP

51
Q

Single piece of wire, spiraled around the turnbuckle buckle and passes through the center hole twice

A

SINGLE WRAP SPIRAL

52
Q

Two single wrap safeties, one in each direction

A

DOUBLE WRAP

53
Q

Two single wrap spirals, one in each direction

A

DOUBLE WRAP SPIRAL

54
Q

Used in place of safety wire to safety turnbuckles if the turnbuckle hardware is drilled to accommodate this type of clip.

A

SAFETY CLIPS

55
Q

have replaced copper. However, it is not flexible and more difficult to bend and flare without cracking.

A

Aluminum-alloy and corrosion-resistant steel

56
Q

is used in areas that are subject to physical damage from dirt, debris, and corrosion caused by moisture, exhaust fumes, and salt air. Such areas include flap wells and external brake lines.

A

CORROSSION-RESISTANT STEEL

57
Q

Always cut it approximately 10 longer than the tube being replaced as a margin of safety for minor variations in bending.

A

TUBE CUTTING

58
Q

When duplicating these lines, you must be able to produce bends that are 75% of the original tube diameter and free of kinks.

A

TUBE BENDING

59
Q

Secures lines which are subject to vibration.

A

RUBBER CUSHIONED CLAPMS

60
Q

Used in areas that are not subject to vibration and typically consists of a metal band formed into a circle.

A

PLAIN CLAPMS

61
Q

Have an electrical lead that is connected to the aircraft structure to ground a tube.

A

BONDED CLAPMS

62
Q

Consists of an inner liner covered with layers of reinforcement to provide strength, and an outer cover to protect from physical damage.

A

FLEXIBLE FLUID LINES

63
Q

Form of synthetic rubber that is abrasion resistant and used with petroleum-based fluids

A

NEOPRENE

64
Q

Synthetic rubber compound that is also used to carry petroleum-based products.

A

BUNA-N

65
Q

Synthetic rubber compound made from petroleum raw materials and breaks down if used with petroleum products.

A

BUTYL

66
Q

Compatible with nearly every liquid used.

A

TEFLON

67
Q

Made of cotton, rayon, polyester fabric, carbon-steel wire, or a stainless steel wire braid.

A

REINFORCEMENT LAYERS

68
Q

Made of rubber-impregnated fabric or stainless steel braid to protect the hose from physical damage.
