Card 1
Question: What types of micrometer calipers?
Answer: Outside micrometer, inside micrometer, depth micrometer, and thread micrometer.
Card 2
Question: How often should torque wrenches be calibrated according to the content?
Answer: Depending on the tool, between 6 months to 12 months.
Card 3
Question: Where would an aircraft operator find approved inspection programs in addition to 100-hour and annual inspections?
Answer: In the aircraft manufacturer's maintenance manual and the Instruction for Continued Airworthiness (ICA).
Card 4
Question: Why must a steel part be magnetized both circularly and longitudinally during magnetic particle inspection?
Answer: To detect faults that extend across (transverse) as well as lengthwise within the part.
Card 5
Question: Which nondestructive method is suitable for detecting surface cracks in aluminum castings and forgings?
Answer: Dye Penetrant Inspection (DPI) or Fluorescent Penetrant Inspection (Zyglo/FPI).
Card 6
Question: Briefly, what are the key steps when performing a dye-penetrant inspection?
Answer: Thoroughly clean the metal surface, dry completely, apply penetrant, remove penetrant from the surface, dry the part, apply developer, then inspect an
Card 7
Question: Summarize the procedure for performing a magnetic particle inspection.
Answer: Thoroughly clean all grease, oil, and dirt from the magnetic metal part (iron or steel), magnetize the part, then apply ferromagnetic particles (liqui
Card 8
Question: Which inspection method is most appropriate for checking a nonferrous metal part for intergranular corrosion?
Answer: Eddy current inspection method.
Card 9
Question: Which inspection method is most appropriate for checking the internal structure of an airplane wing for corrosion?
Answer: X-ray inspection.
Card 10
Question: Why must engine parts inspected by the magnetic particle method be completely demagnetized afterward?
Answer: If not completely demagnetized, they will attract steel particles produced by engine wear, causing damage to bearing surfaces.
