FAA AMT (Aviation Maintenance Technician) Airframe Practice Exam

Question: 1 / 1030

Why is the main fuel strainer located at the lowest point in the fuel system?

To facilitate easy maintenance

To trap any small amount of water that may be present in the fuel system

The main fuel strainer is located at the lowest point in the fuel system because water is heavier than fuel and therefore will settle at the bottom. By having the strainer at the lowest point, any water in the fuel system will be properly trapped and prevented from reaching the engine. Option A is incorrect because while easy maintenance may be a benefit, it is not the primary reason for the location of the strainer. Option C is incorrect because fuel flow can still occur even if the strainer is not at the lowest point. Option D is incorrect because the location is not solely for the convenience of pilots, but rather for the safety and effectiveness of the fuel system.
