What actions should be taken if a hydraulic stationary connection has a static leak?

When there is a static leak in a hydraulic stationary connection, the best course of action is to notify maintenance to repair it. Hydraulic systems are critical for the safe operation of aircraft, as they control essential functions such as flight control surfaces, landing gear, and brakes. A leak indicates that there is a failure in the system that could lead to a loss of hydraulic fluid, potentially compromising the aircraft's operational safety.

Addressing the leak promptly through maintenance ensures that the root cause is identified and properly fixed, thereby preventing further issues or operational risks. This approach aligns with best practices in aviation safety, as it prioritizes thorough repair over temporary fixes or neglect of the problem.

Other options, such as replacing the fluid, sealing the connection with tape, or ignoring a small leak, do not provide a long-term solution and can further endanger the aircraft's performance and safety. It's essential that such issues are handled professionally to maintain the integrity of the hydraulic system.
