What type of gauge must be used to ensure compliance after swaging control cables?

The correct choice involves a go-no-go gauge, which is pivotal in ensuring that control cables are swaged properly. This tool functions in a straightforward manner: it indicates whether the swaged fitting meets the required specifications. A go-no-go gauge typically features two ends or sections marked as "go" and "no-go." When the swaged fitting passes the "go" end, it confirms that the fitting has been swaged correctly and is safe for usage. Conversely, if the fitting does not pass the "go" end or passes the "no-go" end, it indicates a failure in the swaging process, necessitating rework or replacement to ensure safety and compliance with regulatory standards.

Using this type of gauge is particularly important in aviation, where precision is critical for the safe operation of flight controls. The other tools listed, such as digital gauges, pressure gauges, and calipers, serve different purposes. Digital gauges and calipers can measure dimensions but may not specifically indicate whether a swaged fitting is acceptable based on the required specifications. Pressure gauges are not relevant in this context, as they are used to measure fluid or gas pressure rather than the integrity of swaged fittings. Therefore, the go-no-go gauge stands out as the appropriate choice
