1. The primary purpose of an aircraft maintenance technician performing
a pre-flight inspection is to:
A. Identify minor aesthetic issues.
B. Detect conditions that may adversely affect flight safety.
C. Confirm the flight plan with the pilot.
D. Check fuel prices at the airport.
Rationale: A pre-flight inspection is conducted to find conditions that
could compromise safety, not for aesthetics, planning, or fuel
pricing._
2. According to standard maintenance practice, the torque value for
aircraft hardware should be obtained from:
A. The technician’s experience.
B. A generic aviation handbook.
C. The manufacturer’s maintenance manual.
D. The Federal Aviation Regulations Part 91.
Rationale: Torque specifications must be sourced directly from the
aircraft or component manufacturer’s documentation._
,3. An aircraft wood structure showing signs of dry rot should be:
A. Painted to seal the surface.
B. Inspected and repaired according to the manufacturer’s
procedures.
C. Left alone if the aircraft still flies normally.
D. Treated with penetrating oil.
Rationale: Wood rot affects structural integrity and requires
manufacturer-approved repair procedures, not superficial
treatment._
4. When replacing an aircraft tire, which factor is most critical?
A. Tire color.
B. Manufacturer’s country of origin.
C. Correct size and load rating.
D. Price of the tire.
Rationale: The correct tire size and load rating ensure safe operation
under expected loads and speeds._
5. For a reciprocating aircraft engine, the normal operating range of oil
temperature is typically:
A. Below 50°F.
B. Between 180°F and 220°F.
C. Above 300°F constantly.
D. Exactly 250°F.
Rationale: Most aircraft piston engines operate efficiently and safely
with oil temperatures in the 180–220°F range._
6. The most effective method of corrosion prevention on aluminum
aircraft structures is:
A. Covering with cloth.
B. Sandblasting periodically.
C. Proper cleaning, priming, and protective coatings.
, D. Regularly applying saltwater.
Rationale: Corrosion control relies on cleanliness and protective
coatings, not abrasive or corrosive substances._
7. An aircraft spark plug that shows black, sooty deposits on the insulator
most likely indicates:
A. Overly lean mixture.
B. Overly rich mixture.
C. Low engine oil.
D. High engine compression.
Rationale: Black soot on spark plugs is characteristic of a rich fuel/air
mixture._
8. When performing an aircraft annual inspection, what document must
be completed to return the aircraft to service?
A. Pilot’s logbook entry.
B. Maintenance release/Airworthiness approval tag.
C. Fuel receipt.
D. Weather report.
Rationale: An annual inspection must conclude with a properly
executed maintenance release or airworthiness approval tag._
9. Which NDT method is best for detecting surface cracks on metal
aircraft components?
A. Radiographic inspection.
B. Ultrasonic inspection.
C. Dye penetrant inspection.
D. Eddy current inspection.
Rationale: Dye penetrant inspection excels at finding surface cracks
by revealing discontinuities._
10. In aircraft electrical systems, the primary purpose of a circuit
breaker is to:
