During a daily inspection, what should be wiped with a lint free cloth and hydraulic fluid?

The correct answer highlights the importance of maintaining the hydraulic system's integrity and cleanliness. During a daily inspection of the Super Hornet, hydraulic pistons on all struts should be wiped with a lint-free cloth and hydraulic fluid. This practice serves several purposes: it helps to remove any dirt, debris, or contaminants that could affect the functionality of the hydraulic system, and it ensures that the hydraulic pistons are properly lubricated. Keeping these components clean is essential for the safe operation of the aircraft, as any buildup could hinder the movement of the struts, potentially leading to mechanical failures.

This procedure is particularly important given that hydraulic systems are critical for the control surfaces of the aircraft, landing gear operation, and various other systems. Ensuring that the pistons are clean and adequately lubricated helps to prolong their lifespan and maintain reliable performance.

While wiping the exterior of the aircraft, the cockpit instruments, or the fuel tanks might be part of other inspection tasks, these actions do not specifically address the need for cleanliness and lubrication of critical internal components like the hydraulic pistons, making them less relevant in the context of this question.
