What should be inspected regarding vibration absorbers during a preflight check?

• A. Presence of any cracks
• B. Free movement and no fluid leakage
• C. Color and aesthetic condition
• D. Weight and mounting stability

Answer: (B)

During a preflight check, it is essential to inspect vibration absorbers primarily for their free movement and to ensure there is no fluid leakage. Vibration absorbers are critical components that help reduce noise and vibration in machinery and aircraft systems. If these absorbers are functioning correctly, they should allow for free movement without any hindrance, which indicates that they can adequately perform their role in dampening vibrations.

Fluid leakage can indicate a failure in the absorber’s ability to function, as many vibration absorbers utilize fluids to facilitate damping. If there is a leak, the effectiveness of the system could be compromised, leading to increased wear and potential failure of the component or other connected systems. Therefore, ensuring that there is no fluid leakage and confirming that the absorbers can move freely is crucial for maintaining the overall safety and performance of the lifting system.

Other aspects, such as cracks or aesthetic conditions, may be important, but they do not directly affect the operational effectiveness of the vibration absorbers in the same way that movement and fluid integrity do. Checking weight and mounting stability can also be important, but the primary concern during a preflight check is the function and integrity of the absorbers.
