Where is breakage most likely to occur in control cable wires?

• A. At the control stick
• B. Where cables pass over pulleys
• C. Near the connection points
• D. At the inspection holes

Answer: (B)

Breakage in control cable wires is most likely to occur where the cables pass over pulleys. This area is critical because the cables experience significant bending and friction as they navigate the pulleys, which can lead to wear and tear over time. The repetitive motion can create stress points and increase the likelihood of fraying or breaking. In contrast, while breakage can happen at the control stick, near connection points, or at inspection holes, these areas generally do not undergo the same degree of mechanical stress and movement as the sections that go over pulleys. The pulleys introduce a combination of tension and friction that significantly contributes to the deterioration of the cables, making this location more prone to failure compared to the others. Thus, proper maintenance and regular inspections of the pulleys and the cables they support are essential for ensuring system reliability and safety.
