FAA REPAIRMAN CERTIFICATE LIGHT-SPORT AIRCRAFT (LSA) INSPECTION
AIRPLANE EXAM 2026
DOCUMENT OVERVIEW
• This comprehensive study guide contains 200 practice questions designed to
prepare candidates for the FAA Repairman Certificate LSA Inspection exam,
covering all critical inspection and maintenance procedures, airworthiness
standards, and regulatory requirements.
• Master the material by reviewing each question's detailed rationale, focusing on
areas where you struggle, and using this as a reference guide during practical
inspections and annual compliance checks.
EXAMINATION QUESTIONS
QUESTION 1
Before conducting any inspection on a light-sport aircraft, what is the primary
regulatory document that an LSA repairman must consult?
A) The aircraft manufacturer's service bulletins
B) The Federal Aviation Regulations Part 43
C) The aircraft's current insurance policy
D) The local airport authority's guidelines
E) The pilot's operating handbook alone
CORRECT ANSWER: B) The Federal Aviation Regulations Part 43
,Rationale: Part 43 of the Federal Aviation Regulations establishes the general
operating rules for the maintenance, preventive maintenance, rebuilding, and
alteration of aircraft. Every LSA repairman must use Part 43 as the foundational
regulatory document before conducting any inspection or maintenance task. This
regulation provides the framework for what can and cannot be performed and
under what conditions.
QUESTION 2
Which of the following best describes the primary purpose of a 100-hour
inspection on light-sport aircraft?
A) To replace all fluids and filters regardless of condition
B) To identify and correct any defects that would render the aircraft unairworthy
C) To document maintenance history for resale purposes only
D) To comply with manufacturer's warranty requirements
E) To reduce insurance premiums for the aircraft owner
CORRECT ANSWER: B) To identify and correct any defects that would
render the aircraft unairworthy
Rationale: The 100-hour inspection is a comprehensive examination designed to
discover any defects or conditions that might affect airworthiness. The goal is not
merely routine replacement but thorough evaluation and correction of any issues
found. This differs from an annual inspection primarily in scope and allowed
maintenance personnel (can be performed by repair stations or appropriately
certified technicians).
QUESTION 3
What is the minimum acceptable depth of tread on an aircraft tire before it
must be replaced?
A) 1/32 inch
,B) 2/32 inch
C) 3/32 inch
D) 4/32 inch
E) 5/32 inch
CORRECT ANSWER: B) 2/32 inch
Rationale: According to TSO standards and general aviation maintenance practices,
aircraft tires must be replaced when tread depth reaches 2/32 inch. This minimum
ensures adequate safety margin and braking efficiency, particularly during wet
weather operations. Tires worn below this limit pose a safety hazard and reduce
braking performance.
QUESTION 4
During a visual inspection of an aluminum fuselage, you notice a small area of
white powdery corrosion. What is this condition commonly called?
A) Intergranular corrosion
B) White corrosion or exfoliation
C) Stress corrosion cracking
D) Galvanic corrosion
E) Pitting corrosion
CORRECT ANSWER: B) White corrosion or exfoliation
Rationale: White powdery corrosion on aluminum is typically white corrosion or
exfoliation. This occurs when aluminum oxidizes and forms a white oxide layer.
Exfoliation corrosion specifically affects the grain boundaries beneath the surface,
causing layering and flaking. While it appears superficial, it can indicate deeper
structural problems if extensive.
QUESTION 5
, What is the correct procedure for checking the magnetic compass deviation
on an LSA before flight?
A) Align the aircraft with magnetic north on the runway
B) Fly the aircraft in specific magnetic directions and compare compass readings
with gyroscopic heading
C) Place the aircraft on a compass rose and record headings at 90-degree intervals
D) Verify the compass is securely mounted in the instrument panel
E) Calculate deviation using the magnetic declination map
CORRECT ANSWER: C) Place the aircraft on a compass rose and record
headings at 90-degree intervals
Rationale: The proper procedure for checking compass deviation involves
positioning the aircraft on a compass rose (a large marked circle at the airport) and
recording compass readings at 0°, 90°, 180°, and 270° magnetic headings. This
method allows for accurate determination of deviation caused by the aircraft's
magnetic field and electrical systems. Any significant deviation requires
compensation.
QUESTION 6
Which inspection method is most effective for detecting internal corrosion
within hollow aircraft structural members?
A) Visual inspection with a flashlight
B) Eddy current inspection
C) Ultrasonic thickness testing
D) Tap testing with a small hammer
E) Borescope inspection with documentation
CORRECT ANSWER: E) Borescope inspection with documentation
