FAA AMT (Aviation Maintenance Technician) Airframe Practice Exam

The most common method of attaching a pin or socket to an individual wire in an MS electrical connector is by crimping. Crimping provides a secure and reliable connection between the wire and the pin/socket without the need for additional heat application like soldering or welding, making it a preferred method in aviation maintenance. Soldering involves melting a metal alloy to join the wire and pin/socket, which is not ideal for this application. Welding, commonly used for metal parts, is not suitable for delicate electrical connections. Gluing may not provide the necessary mechanical strength and conductivity required for electrical connections. Therefore, crimping is the correct and most commonly used method for this purpose.
