1. Which statement best describes the purpose of the FAA Aviation
Maintenance Technician (AMT) General knowledge examination in the
overall mechanic certification process?
A. It evaluates only the applicant’s ability to perform engine overhaul
procedures before any other testing is permitted.
B. It establishes foundational knowledge common to both the Airframe and
Powerplant ratings, which is tested before the applicable rating
examinations.
C. It replaces the oral and practical examinations for applicants graduating
from an FAA-approved AMT school.
D. It is required only for applicants seeking an Inspection Authorization
rather than an Airframe or Powerplant rating.
Answer: B
The General examination evaluates foundational subjects common to both
mechanic ratings, and the FAA requires the General knowledge test before
the Airframe and/or Powerplant knowledge tests. Applicants must
subsequently complete the applicable oral and practical examinations.
, 2. An aviation maintenance technician is using the relationship between
mass, acceleration, and force to determine the force required to
accelerate an aircraft component. Which equation correctly expresses
Newton’s second law?
A. F = m/a
B. F = a/m
C. F = ma
D. F = m + a
Answer: C
Newton’s second law states that force equals mass multiplied by
acceleration, expressed as F = ma. This relationship is fundamental to
understanding aircraft motion, structural loads, and mechanical systems.
3. A technician needs to determine the area of a rectangular inspection
panel measuring 8 inches by 15 inches. What is the area of the panel?
A. 23 square inches
B. 46 square inches
C. 120 square inches
D. 240 square inches
Answer: C
The area of a rectangle is calculated by multiplying length by width.
Therefore, 8 × 15 = 120 square inches.
4. An aircraft maintenance technician must determine the volume of a
cylindrical component. Which mathematical relationship should be
used when the cylinder has radius r and height h?
A. V = πr²h
B. V = 2πrh
C. V = πrh²
D. V = r²/h
,Answer: A
The volume of a cylinder is calculated as V = πr²h. Correct identification of
geometric relationships is important when calculating capacities,
dimensions, and material requirements during maintenance.
5. A force of 50 pounds is applied to a wrench 2 feet from the center of
rotation. What torque is produced about the center of rotation?
A. 25 foot-pounds
B. 50 foot-pounds
C. 100 foot-pounds
D. 200 foot-pounds
Answer: C
Torque equals force multiplied by the perpendicular moment arm.
Therefore, 50 pounds × 2 feet produces 100 foot-pounds of torque.
6. A mechanic is converting a measurement from decimal inches to a
fractional inch measurement. What is 0.75 inch expressed as a
common fraction?
A. 1/4 inch
B. 1/2 inch
C. 3/4 inch
D. 7/8 inch
Answer: C
The decimal 0.75 is equivalent to 75/100, which reduces to 3/4. Accurate
conversion between decimal and fractional measurements is important
when using aircraft drawings and precision measuring instruments.
7. When interpreting an aircraft drawing, what is the primary purpose of
a dimension line?
, A. To identify the material composition of a component
B. To indicate a measured distance or size
C. To show the direction of electrical current
D. To identify the inspection interval for the component
Answer: B
Dimension lines communicate the size or distance represented on an
engineering drawing. They allow the technician to determine the required
dimensions of parts and features accurately.
8. A technician is examining an aircraft drawing and encounters a
sectional view. What is the primary purpose of a sectional view?
A. To display only the external finish of a component
B. To show the internal features of an object that may otherwise be hidden
C. To identify the weight and balance limitations of the aircraft
D. To show only electrical wiring connections
Answer: B
A sectional view represents an object as though a portion has been cut
away, allowing internal construction and features to be clearly shown.
9. Which material property describes a material’s ability to resist
permanent deformation when subjected to an applied load?
A. Elasticity
B. Hardness
C. Density
D. Conductivity
Answer: A
Elasticity is the ability of a material to return toward its original shape
after the applied load is removed, provided the elastic limit has not been
exceeded.
