AFAB 115 Final Study Guide Latest 2025 Fully Solved
What does the aircraft structures basic construction consists of? - Answers The fuselage, wings,
empennage, landing gear, and powerplants.
What should the bearing strength of the sheet metal and the shear strength of the rivet be? - Answers
relatively equal
True or False: the shear strength of the rivet must be greater than the bearing strength of the sheet
metal - Answers True
What are the parts of an aircraft structure designed to carry loads and or stresses called? - Answers
structural members
What is a spar? - Answers The wings principle structural member
What are the Ailerons, Rudder, and Elevator? - Answers The three Primary flight Control Surfaces of an
aircraft
What are the three secondary control surfaces? - Answers The Slats, Spoilers, and Flaps.
What are the purposes of Slats and Flaps? - Answers To increase the camber of a wing, and increase lift
at slower speeds
What is the purpose of spoilers? - Answers To slow the aircraft and disrupt the lift of an airfoil.
What are structural supports that are under the aircraft skin? - Answers Longerons, bulkheads, and
stringers
True or False: Longerons do not run the entire length of the aircraft fuselage. - Answers False.
(They do run the entire length)
What are are tension, compression, torsion, shear, and bending? - Answers The five major stresses that
act on an aircraft
What is strength? - Answers The ability of a material to withstand forces, which tend to deform it in any
direction, and the ability of that material to resist stress without breaking
What is shear strength? - Answers The point at which a materials would fail under shear force
What is ductility? - Answers The property of a metal, which permits it to be permanently drawn, bent, or
twisted into various shape without breaking
What is the ability of a material to resist the forces that tend to damage it at the point of applied load
called? - Answers bearing strength
, What does a metal which can be hammered, rolled, or pressed, into various shapes without cracking,
breaking, or having some other detrimental effect have? - Answers A high malleability
What is brittleness? - Answers The property of a metal, which allows little bending, or deformation
without shattering
What is the point at which load would cause an initial indication of a permanent distortion called? -
Answers yield strength
True or false: Tensile strength is measured by the resistance of a material to a force that would tend to
pull it apart. - Answers True
True or false: The property of metal to return to its natural shape is called ductility. - Answers False
(It is called elasticity)
What is The outer covering of an aircraft called? - Answers The skin
What is an example of the bearing strength of a joint being insufficient? - Answers If a bolt were
installed in a hole that was too large, and the head was pulled through the material when torque was
applied
What is a non flammable, chromic acid based coating chemical? - Answers Alodine 1201
What does Alodine 1201 produce? - Answers A chrome conversion coating on aluminum and its alloys
What color is applied Alodine? - Answers gold or tan
What does Applied Alodine do? - Answers It becomes part of the aluminum surface
What does Alodine create? - Answers A chrome conversion coating that allows for both paint adhesion
and corrosion resistance
What is the Alodine Application process? - Answers Clean the part with an approved solvent solution,
water rinse the part after solvent clean, place the part into the Alodine for a specified time, remove the
part and water rinse, allow the part to air dry.
True or false: Material used on aircraft, for the replacement or reinforcement of damage, should always
be weaker material than the original material. - Answers False
(It should never be weaker)
What is an example of negligible damage? - Answers Small dents, scratches, cracks, or holes that can be
sanded or hammered out or repaired without the use of additional material
