FAA AMT (Aviation Maintenance Technician) Airframe Practice Exam

In the installation of aircraft wiring, what should be accomplished?

1. Locating the bundle below flammable fluid lines and loosely clamping to structure

2. Locate the bundle above flammable fluid lines and loosely clamping to structure

3. Locating the bundle below flammable fluid lines and securely clamping to structure

4. Locate the bundle above flammable fluid lines and securely clamp to structure

The correct answer is: Locate the bundle above flammable fluid lines and securely clamp to structure

When installing aircraft wiring, it is crucial to ensure the safety of the aircraft. By locating the wiring bundle above flammable fluid lines, it helps to minimize the risk of potential leaks or spills causing damage to the wiring. Additionally, securely clamping the wiring to the aircraft structure ensures that it remains in place during flight and does not experience unnecessary movement or vibrations that could lead to wear and potential electrical issues. Option A is incorrect as locating the bundle below flammable fluid lines could expose the wiring to potential hazards in the event of a leak or spill. Option B is incorrect as loosely clamping the wiring to the structure may result in movement during flight, which could lead to chafing or other issues. Option C is incorrect as securely clamping the wiring below flammable fluid lines could still expose the wiring to potential risks in case of a fluid leak.
