Question 1
During a routine airframe inspection, why is it essential to consult the
manufacturer's maintenance manual before beginning any structural repair
procedure?
A. To reduce paperwork requirements after maintenance is complete
B. To ensure approved repair methods, materials, and inspection criteria are
followed correctly
C. To eliminate the need for a final inspection by certificated personnel
D. To substitute FAA regulations with company maintenance procedures
Correct Answer: B
Rationale: Manufacturer maintenance manuals provide FAA-approved
procedures, materials, dimensions, and inspection standards. Following
them helps maintain aircraft airworthiness. Options A, C, and D incorrectly
describe documentation or regulatory responsibilities.
Question 2
Which aluminum alloy designation is most commonly selected for aircraft
structural components because of its excellent strength-to-weight ratio?
,A. 1100 aluminum alloy
B. 2024 aluminum alloy
C. 3003 aluminum alloy
D. 5052 aluminum alloy
Correct Answer: B
Rationale: 2024 aluminum alloy is widely used in aircraft structures because
it provides high strength while maintaining relatively low weight. The other
alloys are generally chosen for corrosion resistance or formability rather
than primary structural strength.
Question 3
When inspecting a riveted aircraft skin panel, which condition should be
considered the strongest indication that further corrective maintenance is
necessary?
A. Uniform paint discoloration around fasteners
B. Loose or smoking rivets indicating movement between joined materials
C. Minor surface scratches within allowable limits
D. Normal manufacturing marks on the aluminum surface
Correct Answer: B
Rationale: Smoking rivets produce dark streaks caused by movement and
fretting between components, indicating looseness or structural issues
requiring repair. The remaining conditions generally do not automatically
require corrective maintenance.
Question 4
,Why must corrosion be removed from an aircraft structure as soon as it is
discovered during a scheduled inspection?
A. Corrosion improves electrical bonding between components
B. Corrosion weakens structural integrity and can spread if left untreated
C. Corrosion only affects aircraft appearance and resale value
D. Corrosion always disappears after repainting the affected area
Correct Answer: B
Rationale: Corrosion reduces material strength, accelerates deterioration,
and may eventually lead to structural failure. Prompt treatment prevents
additional damage and restores protective finishes.
Question 5
Which measuring instrument provides the greatest accuracy when
determining the diameter of a precision aircraft fastener?
A. Steel ruler
B. Tape measure
C. Vernier caliper or micrometer
D. Combination square
Correct Answer: C
Rationale: Vernier calipers and micrometers provide precise dimensional
measurements needed for aircraft maintenance. Rulers and tape measures
lack the required accuracy for precision fasteners.
Question 6
, When replacing a damaged solid rivet in an aircraft skin, what should be the
mechanic's primary concern before installing the replacement rivet?
A. Matching the aircraft paint color
B. Selecting the correct rivet material, diameter, and length specified by
approved data
C. Installing the longest available rivet for additional strength
D. Using adhesive instead of proper rivet installation procedures
Correct Answer: B
Rationale: Proper rivet size and material ensure the repaired joint meets
structural requirements. Oversized rivets, adhesives, or cosmetic
considerations cannot replace approved installation methods.
Question 7
What is the principal purpose of installing inspection panels on an aircraft
airframe during the manufacturing process?
A. To improve cabin insulation
B. To allow convenient access for inspection, maintenance, and repairs
C. To increase aircraft cruising speed
D. To strengthen the fuselage against bending loads
Correct Answer: B
Rationale: Inspection panels provide maintenance access to internal
components while minimizing unnecessary structural disassembly. They are
not intended to improve speed or structural strength.
