    (414) The type of self-sealing valves installed in the H–60 fuel lines to contain the fuel in case of a helicopter crash or malfunction is

    • Inertia.

    • Impact.

    • Shutoff.

    • Breakaway.

    Correct Answer
    A. Breakaway.
    Explanation
    Breakaway valves are installed in the fuel lines of H-60 helicopters to contain the fuel in case of a crash or malfunction. These valves are designed to break away or disconnect from the fuel lines when a certain force or pressure is applied. This helps to prevent fuel leakage and reduce the risk of fire or explosion in the event of an accident. The breakaway feature allows the valves to separate easily, sealing off the fuel and preventing it from escaping.

    (418) In comparison to other aircraft systems, troubleshooting the fuel system is more difficult because

    • The fuel system is more complex.

    • You must work with a team of mechanics.

    • The mechanical components are hard to access.

    • Schematics in the technical orders are hard to interpret.

    Correct Answer
    A. The mechanical components are hard to access.
    Explanation
    The correct answer is that the mechanical components are hard to access. This means that when troubleshooting the fuel system, it is more difficult because the parts of the system that need to be inspected or repaired are not easily reachable. This can make it challenging for mechanics to identify and fix any issues with the fuel system.

    (421) To perform continuity and voltage checks on H–60 electrical systems, you would use

    • A test light.

    • A multimeter.

    • A jumper wire.

    • An electrodialysis meter.

    Correct Answer
    A. A multimeter.
    Explanation
    A multimeter is a versatile tool that can be used to perform continuity and voltage checks on electrical systems. It can measure voltage, current, and resistance, making it suitable for testing the continuity of electrical connections and checking the voltage levels in the H-60 electrical systems. A test light can also be used for continuity checks, but it may not provide accurate voltage readings. A jumper wire is used to bypass a component or connection temporarily, and an electrodialysis meter is not relevant to performing continuity and voltage checks.

    (424) A main rotor (MR) blade on an H–60 is allowed to move about its axis for pitch changes by the

    • Elastomeric bearing.

    • Hydraulic dampers.

    • Hub sleeve.

    • Blade grip.

    Correct Answer
    A. Elastomeric bearing.
    Explanation
    The correct answer is elastomeric bearing. An elastomeric bearing allows the main rotor blade on an H-60 to move about its axis for pitch changes. Elastomeric bearings are made of a rubber-like material that provides flexibility and dampens vibrations, allowing for smooth and controlled movement of the rotor blade. Hydraulic dampers, hub sleeve, and blade grip are not responsible for pitch changes in this context.
