Which of the following elements can lead to the failure of a control cable?

The option indicating that both corrosion and improper tension can lead to the failure of a control cable is correct because both of these factors significantly affect the integrity and functionality of control cables in aircraft systems.

Corrosion is a critical issue as it deteriorates the material properties of the cable, potentially leading to weakened structures that may eventually break under normal operational stresses. Control cables are often made of metal and exposed to various environmental conditions that can promote corrosion, such as moisture, salt, and other corrosive agents. This degradation can result in an inability to transmit control inputs effectively, creating safety risks in flight operations.

Improper tension is another factor that can lead to control cable failure. If the cable is too loose, it may not perform its function effectively, causing imprecise control movements. Conversely, if the cable is too tight, it can create excessive stress on the cable and its connecting hardware, leading to premature wear or snap under load. Ensuring that control cables are maintained at the correct tension is essential for reliable operation and avoiding failures.

While excess lubrication may have an impact on cable operation, it typically does not lead directly to a failure scenario as corrosion and improper tension can. Excess lubrication might cause issues like slippage or difficulty of movement, but it is
