A technician has put a swaged end on a 1/8th cable, and has brought it to you for inspection. The shank diameter should be:

In the context of inspecting a swaged end on a 1/8-inch cable, it is vital to understand the specifications that pertain to cable diameters and the corresponding shank diameters for fittings. For a 1/8-inch cable, the correct shank diameter that is compatible with this size is indeed 0.219 inches.

This measurement is important because it ensures that the swaged fitting properly accommodates the cable and maintains structural integrity under load. When fittings and cables are mismatched in diameter, this can lead to failures during operation, as they may not bear loads effectively or could allow movement that damages the cable or fitting.

The other diameter options provided do not align with standard practices for a 1/8-inch cable. Therefore, understanding the appropriate measurements for swaging and the relationship between cable size and shank diameter is critical for maintaining safety and reliability in aircraft systems.
