During a preflight check, what should be inspected about flexible hydraulic hoses?

During a preflight check, it is crucial to inspect the flexible hydraulic hoses for proper tension between fittings. Ensuring there is no slack between fittings is significant because slack can lead to increased wear or movement that might damage the hoses or compromise the hydraulic system's integrity. If the hoses have slack, it may increase the risk of them rubbing against other components, which can create leaks or complete failure of the hydraulic systems during operation.

Assessing the proper installation of hydraulic hoses is essential for safety and reliability. A tightly secured hose will maintain the necessary pressure within the system and function correctly without risk of disconnecting or sustaining damage. This attention to detail is paramount in maintaining operational readiness and ensuring the safety of the aircraft.
