What is the purpose of the Hydraulic Fluid Contamination Analysis?

• A. Aids in determining fluid containment level
• B. Maintains fluid purity on Class 5 aircraft and Class 3 GSE
• C. Provides information on materials and procedures to prevent corrosion
• D. Detects leaks in the hydraulic system

Answer: (A)

The main idea is to determine how dirty the hydraulic fluid is, so you can gauge the cleanliness level of the fluid and the potential risk to hydraulic components. By analyzing contaminants, technicians can quantify the contamination level, which tells you whether the fluid is still within acceptable limits or if it needs filtration, replacement, or a flushing action to prevent wear and damage to pumps, valves, and actuators. This information also helps pinpoint when and how to address contamination sources to keep the system reliable.

The other options don’t fit the purpose because this analysis isn’t about maintaining purity on specific aircraft or ground support equipment as a routine, it doesn’t focus on materials and procedures to prevent corrosion, and it isn’t a method for detecting leaks in the hydraulic system.
