  • 1

    Cabin upholstery materials installed in current standard category airplanes must

    Be at least flame resistant.

  • 2

    On a semi monocoque fuselage, the skin is reinforced by longitudinal structural members called

    Longerons and stringers

  • 3

    A sheet metal repair is to be made using two pieces of 0.0625-inch aluminum riveted together. All rivet holes are drilled for 1/8-inch rivets. The length of the rivets to be used will be

    5/16 inch

  • 4

    A main difference between Lockbolt/Huckbolt tension and shear fasteners (other than their application) is in the

    Number of locking collar grooves

  • 5

    The Dzus turnlock fastener consists of a stud, grommet, and receptacle. The stud length is measured in

    Hundredths of an inch

  • 6

    The classification for fiberglass reinforcement material that has high resistivity and is the most common is

    E-glass

  • 7

    What precaution, if any, should be taken to prevent corrosion inside a repaired metal honeycomb structure?

    Prime the repair with a corrosion inhibitor and seal from the atmosphere.

  • 8

    The installation of Cherrymax and Olympic-Lok rivets is accomplished by utilizing

    A pulling tool:

  • 9

    The length of time that a catalyzed resin will remain in a workable state is called the

    Pot life

  • 10

    Repairing advanced composites using materials and techniques traditionally used for fiberglass repairs is likely to result in

    An unairworthy repair.

  • 11

    Which rivet may be used as received without further treatment?

    2117-Т3

  • 12

    When necessary, what type of cutting fluid is usually acceptable for machining composite laminates?

    Water only

  • 13

    The aluminum alloys used in aircraft construction are usually hardened by which method?

    Heat treatment

  • 14

    Repairs or splices involving stringers on the lower surface of stressed skin metal wings are usually

    Permitted but are normally more critical in reference to strength in tension than similar repairs to the upper surface.

  • 15

    When balsa wood is used to replace a damaged honeycomb core, the plug should be cut so that

    The grain is perpendicular to the skin.

  • 16

    A piece of flat stock that is to be bent to a closed angle of 15° must be bent through an angle of

    165°

  • 17

    Which statement is true regarding a cantilever wing?

    No external bracing is needed.

  • 18

    Mild steel rivets are used for riveting

    Steel parts

  • 19

    Fiberglass damage that extends completely through a laminated sandwich structure

    May be repaired.

  • 20

    Proper prepreg composite lay-up curing is generally accomplished by 1. Applying external heat. 2. Room temperature exposure. 3. Adding a catalyst or curing agent to the resin. 4. Applying pressure.

    1 and 4

  • 21

    When repairing a small hole on a metal stressed skin, the major consideration in the design of the patch should be

    The shear strength of the riveted joint.

  • 22

    How does acoustic emission testing detect defects in composite materials?

    By picking up the 'noise of any deterioration that may be present.

  • 23

    A rivet set used to drive MS20470 rivets should

    Have a slightly greater radius than the rivet head.

  • 24

    Which rivet is used for riveting magnesium alloy structures?

    5056 aluminum

  • 25

    Which of these methods may be used to inspect fiberglass/honeycomb structures for entrapped water? 1. Acoustic emission monitoring 2. X-ray 3. Backlighting

    2 and 3

  • 26

    The purpose of a joggle is to

    Allow clearance for a sheet or an extrusion.

  • 27

    When bending metal, the material on the outside of the curve stretches while the material on the inside of the curve compresses. That part of the material which is not affected by either stress is the

    Neutral line

  • 28

    The general rule for finding the proper rivet diameter is

    Three times the thickness of the thickest sheet.

  • 29

    A piece of sheet metal is bent to a certain radius. The curvature of the bend is referred to as the

    Bend radius

  • 30

    Which rivet is used for riveting nickel-steel alloys?

    Monel

  • 31

    Which part of the 2017-36 aluminum alloy designation indicates the primary alloying agent used in its manufacture?

    2

  • 32

    Superficial scars, scratches, surface abrasion, or rain erosion on fiberglass laminates can generally be repaired by applying

    One or more coats of suitable resin (room-temperature catalyzed) to the surface.

  • 33

    The shop head of a rivet should be

    One and one-half times the diameter of the rivet shank:
