FAA Powerplant Written Practice Test

What is the requirement for fuel valves when preparing to remove an engine?

1. They must be left in the open position

2. They must be partially closed

3. They must be fully closed

4. They can be managed remotely without issue

The correct answer is: They must be fully closed

The requirement for fuel valves when preparing to remove an engine is that they must be fully closed. This is a critical safety measure to prevent fuel from leaking or spilling during the engine removal process. When the valves are fully closed, it ensures that there is no potential for fuel flow and helps to mitigate fire hazards associated with fuel exposure. Leaving the fuel valves open, partially closed, or assuming they can be managed remotely could lead to dangerous situations, such as fuel leaks, which not only pose risks for fire but can also contaminate other components and the environment. Ensuring that the valves are properly closed is part of following safe maintenance practices and complying with established protocols for engine removal.
