FAA AMT (Aviation Maintenance Technician) Airframe Practice Exam

Question: 1 / 1030

How do you check the air charge in a hydraulic accumulator?

Increase the hydraulic pressure and measure

Reduce all hydraulic pressure, then observe the reading on the accumulator air gauge

To check the air charge in a hydraulic accumulator, you need to reduce all hydraulic pressure and then observe the reading on the accumulator air gauge. This is the correct method because reducing all hydraulic pressure ensures that the system is at a safe level for inspection, and observing the reading on the accumulator air gauge allows you to determine the current air charge level without any interference from hydraulic pressure.

Options A, C, and D are incorrect:

A. Increasing the hydraulic pressure and measuring would not accurately give you the air charge in the accumulator as the hydraulic pressure would interfere with the reading.

C. Manually inspecting the physical condition of the accumulator does not specifically provide information about the air charge level.

D. Using a special tool to measure the pressure without reducing hydraulic pressure may lead to inaccurate readings due to the interference of hydraulic pressure.
