    When operating a borescope, what part of the borescope illuminates the interior of the area you’re inspecting?

    • Control unit.

    • Light guide tube.

    • Distal tip light guides.

    • Bending section lever.

    Correct Answer
    A. Distal tip light guides.
    Explanation
    The distal tip light guides of a borescope are responsible for illuminating the interior of the area being inspected. These light guides transmit light from the control unit to the distal tip of the borescope, allowing for better visibility and inspection of the area. The control unit and bending section lever are not directly involved in illuminating the interior, while the light guide tube serves as a pathway for the light to travel through.

    Do not use self-locking nuts on

    • Areas near engine inspection points.

    • Engine accessories.

    • Control pulleys.

    • Engine joints.

    Correct Answer
    A. Engine joints.
    Explanation
    Self-locking nuts should not be used on engine joints because they can cause excessive stress and damage to the joint. Engine joints require a certain level of flexibility and movement to accommodate the vibrations and thermal expansion that occur during engine operation. Self-locking nuts, which are designed to prevent loosening, can restrict this movement and lead to premature failure of the joint. Therefore, it is important to use alternative fastening methods that allow for the necessary flexibility and movement in engine joints.

    Which nuts should never be used in areas where the temperature exceeds 250ï‚°F?

    • Plain nuts.

    • Wing nuts.

    • Metallic self-locking nuts.

    • Nonmetallic self-locking nuts.

    Correct Answer
    A. Nonmetallic self-locking nuts.
    Explanation
    Nonmetallic self-locking nuts should never be used in areas where the temperature exceeds 250ï‚°F because they are not designed to withstand high temperatures. The nonmetallic material used in these nuts can melt or degrade at high temperatures, compromising their ability to securely fasten and lock in place. This can lead to loosening or failure of the nuts, posing a safety risk in high-temperature environments. Therefore, it is important to use alternative nuts, such as metallic self-locking nuts, that are specifically designed to withstand higher temperatures.

    Engines inactive for over 180 days must have what accomplished?

    • Motor the engine to circulate the oil.

    • Inspect reservoirs to ensure they are full.

    • Visually inspect compressor for corrosion.

    • Preservation run and fuel system preservation.

    Correct Answer
    A. Preservation run and fuel system preservation.
    Explanation
    Engines that have been inactive for over 180 days need to have a preservation run and fuel system preservation accomplished. This means that the engine should be run for a specific period of time to prevent any damage or deterioration, and the fuel system should be properly preserved to ensure its functionality when the engine is needed again. This process helps to maintain the engine's performance and prevent any potential issues that may arise from long periods of inactivity.

    When metal is attacked by chemical corrosion, it will start

    • Deep within the metal.

    • On the surface of the metal.

    • Throughout the metal all at once.

    • Just under the surface of the metal.

    Correct Answer
    A. On the surface of the metal.
    Explanation
    When metal is attacked by chemical corrosion, it typically starts on the surface of the metal. This is because the surface of the metal is exposed to the external environment, which may contain corrosive agents such as moisture, oxygen, or acids. These corrosive agents react with the metal surface, leading to the formation of corrosion products. Over time, the corrosion may penetrate deeper into the metal, but it usually initiates on the surface.
