1. Which aircraft structural component primarily absorbs the loads
imposed during landing?
A. Fuselage skin
B. Wing spars
C. Landing gear
D. Control surfaces
Rationale: The landing gear is specifically designed to absorb and
dissipate the impact and operational loads encountered during
takeoff, landing, and taxiing. Shock struts, tires, and associated
structural members protect the airframe from excessive stress.
2. What is the purpose of aircraft stringers?
A. To secure flight controls
B. To provide longitudinal strength to the fuselage
,C. To support landing gear retraction
D. To attach wing ribs
Rationale: Stringers are longitudinal structural members that
reinforce the fuselage and help maintain its shape while distributing
loads along the aircraft body. They increase rigidity and resistance to
bending.
3. Which type of rivet is commonly used in aircraft structural repair?
A. Wood screw
B. Sheet metal screw
C. Solid shank rivet
D. Machine bolt
Rationale: Solid shank rivets are widely used in aircraft structures
because of their high shear strength and reliability. They are especially
common in stressed skin aluminum structures.
4. What is the primary purpose of a wing rib?
A. To secure the engine mount
B. To maintain the airfoil shape of the wing
C. To attach landing gear
D. To support the fuselage
,Rationale: Wing ribs provide the contour and aerodynamic shape of
the wing while transferring aerodynamic loads to spars and other
structural components.
5. Which material is most commonly used in modern aircraft skin
construction?
A. Cast iron
B. Magnesium only
C. Aluminum alloy
D. Brass
Rationale: Aluminum alloys are widely used because they provide an
excellent balance of strength, lightweight characteristics, corrosion
resistance, and workability.
6. What is the purpose of a bulkhead in aircraft construction?
A. To cool the engine
B. To provide structural support and divide sections of the fuselage
C. To operate control surfaces
D. To hold fuel tanks in place
Rationale: Bulkheads are structural partitions that strengthen the
fuselage, maintain shape, and separate compartments such as cargo,
cabin, and pressure sections.
, 7. Which corrosion type appears as a white or gray powder on
aluminum surfaces?
A. Stress corrosion
B. Galvanic corrosion
C. Fretting corrosion
D. Surface corrosion
Rationale: Surface corrosion on aluminum often appears as a white or
gray powdery deposit caused by oxidation due to moisture and
environmental exposure.
8. What tool is commonly used to measure rivet diameter?
A. Torque wrench
B. Protractor
C. Micrometer
D. Allen wrench
Rationale: A micrometer provides precise measurements of small
dimensions such as rivet diameters and material thicknesses, making
it essential for aircraft maintenance.
9. Which nondestructive inspection method uses magnetic particles?
A. Ultrasonic inspection
B. Dye penetrant inspection
