INTRODUCTION
This comprehensive assessment is designed to evaluate the knowledge and skills required for an
Aircraft Maintenance Technician. It covers foundational theory, applied professional knowledge,
and technical concepts essential for safe and efficient aircraft maintenance. The exam assesses
regulatory compliance, ethical standards, and practical decision-making through multiple-choice
and scenario-based questions. Emphasis is placed on real-world application, critical thinking, and
professional judgment. Candidates are expected to demonstrate a thorough understanding of
inspection procedures, troubleshooting techniques, and the responsibilities inherent in
maintaining airworthiness. This practice exam serves as a tool to prepare for certification by
simulating the format and rigor of the actual examination.
SECTION ONE – QUESTIONS 1–100
1. Which federal regulation establishes the requirements for the certification of repair
stations?
A. 14 CFR Part 43
B. 14 CFR Part 65
C. 14 CFR Part 145
,🟢 D. 14 CFR Part 147
🔴 Explanation: 14 CFR Part 147 outlines the requirements for aviation maintenance technician
schools, not repair stations. Part 145 specifically governs the certification and operation of
repair stations.
2. What is the primary purpose of a torque wrench?
A. To measure the length of a bolt
B. To apply a specific rotational force to a fastener
C. To loosen over-tightened nuts
D. To measure the diameter of a rivet
🟢 Correct answer: B
🔴 Explanation: A torque wrench is a precision tool used to apply a specific amount of
rotational force (torque) to a fastener, ensuring it is tightened to the manufacturer's
specifications without being over- or under-tightened.
3. A mechanic discovers a crack in a critical wing spar. According to ethical standards, what
is the first action they should take?
A. Attempt to repair the crack using a doubler patch
B. Document the crack and continue with the next task
C. Ground the aircraft and report the finding to a supervisor
D. Order a replacement spar and schedule the repair for the next shift
🟢 Correct answer: C
🔴 Explanation: The discovery of a crack in a critical structural component is an airworthiness
concern. The ethical and professional responsibility of a mechanic is to immediately ground the
aircraft and report the discrepancy to the appropriate authority to prevent an unsafe condition.
4. Which type of corrosion is characterized by a white, powdery deposit on aluminum
surfaces?
A. Galvanic corrosion
B. Pitting corrosion
C. Intergranular corrosion
🟢 D. Surface corrosion
🔴 Explanation: Surface corrosion on aluminum typically appears as a white, powdery deposit.
Galvanic corrosion occurs between dissimilar metals, pitting is localized and deep, and
intergranular corrosion attacks the grain boundaries within the metal.
,5. What is the function of a magneto in an aircraft engine?
A. To charge the battery
B. To provide a high-voltage spark to the spark plugs
C. To regulate the fuel-air mixture
D. To cool the engine cylinders
🟢 Correct answer: B
🔴 Explanation: A magneto is an engine-driven electrical generator that produces high-voltage
pulses to fire the spark plugs. It operates independently of the aircraft's electrical system,
making it a reliable ignition source.
6. When performing a 100-hour inspection, what documentation must be completed?
A. A logbook entry signed by the pilot
B. A maintenance record entry signed by the mechanic
C. A verbal report to the FAA
D. A flight plan
🟢 Correct answer: B
🔴 Explanation: After a 100-hour inspection, the mechanic performing the inspection must
make a maintenance record entry containing the inspection details, the date, and their
signature and certificate number.
7. What is the primary safety hazard associated with lithium-ion batteries installed in
aircraft?
A. They are too heavy
B. They can experience thermal runaway
C. They are difficult to recycle
D. They have a short shelf life
🟢 Correct answer: B
🔴 Explanation: Lithium-ion batteries can undergo thermal runaway, a condition where an
internal short circuit or overcharging leads to a rapid increase in temperature and pressure,
potentially causing a fire or explosion.
8. Which document provides the FAA-approved instructions for maintaining an aircraft in an
airworthy condition?
A. The Pilot's Operating Handbook (POH)
B. The Type Certificate Data Sheet (TCDS)
C. The manufacturer's maintenance manual
, D. The Airworthiness Directive (AD) summary
🟢 Correct answer: C
🔴 Explanation: The manufacturer's maintenance manual provides the FAA-approved
procedures and specifications necessary to maintain the aircraft in an airworthy condition. The
POH is for operations, and the TCDS defines the type design.
9. A mechanic is asked to sign off an annual inspection on an aircraft they have not
personally inspected. What is the correct response?
A. Sign the logbook since a coworker performed the inspection
B. Refuse to sign and explain the legal and ethical violation
C. Sign the logbook but note the coworker's name
D. Sign the logbook under the supervisor's supervision
🟢 Correct answer: B
🔴 Explanation: It is a violation of Federal Aviation Regulations and professional ethics to sign
off on maintenance or an inspection that you did not personally perform. The mechanic must
refuse and explain the legal requirement for a personal inspection.
10. What is the purpose of an Airworthiness Directive (AD)?
A. To provide recommended maintenance intervals
B. To mandate corrective actions for unsafe conditions
C. To certify an aircraft's design
D. To outline pilot training requirements
🟢 Correct answer: B
🔴 Explanation: An Airworthiness Directive is a legally enforceable rule issued by the FAA to
correct an unsafe condition found in a type-certificated product. Compliance is mandatory.
11. Which material is commonly used for aircraft firewalls due to its heat resistance?
A. Aluminum alloy
B. Titanium
C. Stainless steel
D. Magnesium
🟢 Correct answer: C
🔴 Explanation: Stainless steel is commonly used for firewalls because it can withstand high
temperatures and is resistant to corrosion, providing a barrier between the engine
compartment and the cockpit.
