    • 36 hours

    • 24 hours

    • 12 hours

    Correct Answer
    A. 24 hours
    Explanation
    The correct answer is 24 hours. This is the amount of time you should let the edge sealer dry before painting. Allowing the sealer to dry for 24 hours ensures that it has fully cured and will provide a proper surface for the paint to adhere to. Painting too soon can result in the sealer not being fully dry, causing the paint to not adhere properly and potentially leading to peeling or cracking.

    (403) You need to consider heat requirements for which prevailing torque, self-locking nut locking device?

    • Slotted or beam

    • Nonmetallic insert.

    • Deformed thread type

    • Interrupted thread type

    Correct Answer
    A. Nonmetallic insert.
    Explanation
    The correct answer is Nonmetallic insert. Nonmetallic inserts are commonly used as a locking device for prevailing torque, self-locking nuts. These inserts are made of materials such as nylon or plastic and are designed to provide resistance to vibration and prevent the nut from loosening. They offer good heat resistance and can withstand high temperatures, making them suitable for applications where heat requirements need to be considered. Slotted or beam, deformed thread type, and interrupted thread type are not specifically designed to meet heat requirements for prevailing torque, self-locking nut locking devices.

    (421) The probable cause of excessive burrs while cutting tubing with a tube cutter is

    • The tube cutter was rotated in a clockwise direction

    • The tube cutter was rotated in a counterclockwise direction

    • Too little pressure was applied on the cutting wheel at one time

    • Too much pressure was applied on the cutting wheel at one time.

    Correct Answer
    A. Too much pressure was applied on the cutting wheel at one time.
    Explanation
    Excessive burrs can occur while cutting tubing with a tube cutter if too much pressure is applied on the cutting wheel at one time. Applying excessive pressure can cause the cutting wheel to dig into the tubing, resulting in uneven and jagged cuts. This can lead to the formation of burrs, which are rough edges or protrusions on the cut surface. Therefore, it is important to apply the right amount of pressure while using a tube cutter to ensure clean and smooth cuts without excessive burrs.

    (421) How do you remove foreign material from inside a completed tubing assembly?

    • Flush with water

    • Immersion in water.

    • Blow with compressed air only

    • Flush with a technical order (TO) approved solvent

    Correct Answer
    A. Flush with a technical order (TO) approved solvent
    Explanation
    To remove foreign material from inside a completed tubing assembly, the most appropriate method is to flush it with a technical order (TO) approved solvent. This method ensures that the foreign material is effectively dissolved and removed from the tubing assembly, leaving it clean and free from any contaminants. Flushing with water or immersion in water may not be as effective in removing certain types of foreign material, while blowing with compressed air only may not fully eliminate the contaminants. Therefore, using a TO-approved solvent is the best option for thorough cleaning of the tubing assembly.

    (622) What should you do to an aircraft panel before you fine finish the edges?

    • Alodine the panel.

    • Fit test the panel

    • Prime the panel

    • Paint the panel

    Correct Answer
    A. Fit test the panel
    Explanation
    Before fine finishing the edges of an aircraft panel, it is important to fit test the panel. This involves checking whether the panel fits properly in its designated position and aligns correctly with other components. Fit testing ensures that there are no gaps or misalignments, which could affect the overall integrity and functionality of the aircraft. By performing a fit test, any necessary adjustments or modifications can be made before proceeding with the fine finishing process.

    (625) What do you do if one-part sealant does not go on smoothly, easily, and evenly when applying it to an area?

    • Add thinner

    • Discard the sealant

    • Add more accelerators

    • Whip air into the sealant

    Correct Answer
    A. Discard the sealant
    Explanation
    If the one-part sealant does not go on smoothly, easily, and evenly when applying it to an area, the best course of action would be to discard the sealant. This is because a sealant that does not apply smoothly and evenly may not provide an effective seal or may result in an uneven finish. Adding thinner or more accelerators may alter the composition of the sealant and affect its effectiveness. Whipping air into the sealant may introduce air bubbles and further compromise its performance. Therefore, it is best to discard the sealant and use a new one for optimal results.

    (210) What is an advanced form of Inter-granular corrosion?

    • Fatigue corrosion.

    • Filiform corrosion.

    • Crevice cell corrosion.

    • Exfoliation corrosion.

    Correct Answer
    A. Exfoliation corrosion.
    Explanation
    Exfoliation corrosion is an advanced form of intergranular corrosion. It occurs when corrosion penetrates along the grain boundaries of a metal, causing the grains to separate and peel away from the surface. This type of corrosion is commonly observed in aluminum alloys, where it can lead to severe structural damage. Unlike other forms of intergranular corrosion, exfoliation corrosion typically occurs in materials with a high degree of anisotropy, such as rolled or extruded metals. It is characterized by the formation of layers or sheets that peel away from the metal surface, resembling the peeling of an onion.
