1. What is the primary purpose of the Federal Aviation
Regulations (FARs) Part 43?
a) Governs pilot training requirements
b) Outlines aircraft certification standards
c) Provides rules for maintenance, preventive maintenance,
rebuilding, and alterations
d) Covers air traffic control operations
Rationale: FAR Part 43 specifically details who can perform
maintenance and how it should be documented.
2. Which document must a mechanic review before
performing maintenance on an aircraft? a) FAA Form 337
b) Manufacturer’s maintenance manual
c) Weight and balance report
, d) Logbook endorsement
Rationale: The manufacturer’s maintenance manual contains
procedures and specifications necessary for safe maintenance.
3. What is the function of an aircraft’s altimeter?
a) Measures airspeed
b) Measures altitude above sea level
c) Measures pitch angle
d) Measures rate of climb
Rationale: The altimeter uses static pressure to indicate altitude
above mean sea level.
4. What is the advantage of a truss-type fuselage
construction?
a) Less aerodynamic drag
b) Strong and lightweight structure
c) Simplified pressurization
d) Easier to pressurize
Rationale: Truss-type construction provides strength with
relatively low weight by using a framework of tubes.
5. The camber of a wing refers to:
a) Wing thickness
b) Wing length
, c) Curvature of the wing surface
d) Angle of incidence
Rationale: Camber describes the curvature of the wing, which
affects lift generation.
6. Which type of stress tends to stretch a material?
a) Shear
b) Compression
c) Tension
d) Torsion
Rationale: Tension stress is a pulling force that attempts to
elongate a material.
7. Which part of a turbine engine compresses incoming air?
a) Turbine
b) Combustion chamber
c) Compressor
d) Exhaust
Rationale: The compressor raises the pressure of incoming air
before combustion.
8. What is the purpose of a magneto in a reciprocating
engine?
a) Provide lubrication
, b) Provide ignition spark independent of the aircraft’s
electrical system
c) Control fuel mixture
d) Regulate exhaust gases
Rationale: Magnetos generate electrical current for spark plugs,
ensuring ignition without external power.
9. Which FAR Part governs mechanic certification?
a) Part 91
b) Part 43
c) Part 65
d) Part 147
Rationale: FAR Part 65 covers the certification requirements for
mechanics and repairmen.
10. What is the primary function of a carburetor?
a) Compress air
b) Mix fuel and air in proper ratio for combustion
c) Regulate engine oil
d) Cool the cylinders
Rationale: Carburetors meter fuel and mix it with air for
delivery to cylinders.
11. Which color represents 100LL aviation gasoline?
