How many twists per inch should safety wire have?

Safety wire is a critical component used in aviation to secure fasteners and prevent them from loosening due to vibration and dynamic forces. The proper number of twists per inch is essential for ensuring the effectiveness of the wire.

The correct answer indicates that safety wire should have 8 to 10 twists per inch. This range strikes a balance between providing sufficient tension to keep the fastener secure while allowing for flexibility and ease of installation. Too few twists may not create enough friction to hold the fastener securely, while too many twists can make the wire unnecessarily rigid and difficult to manipulate, which can lead to installation errors or failures in securing the component.

This standard is based on industry practices and ensures optimal safety and performance in various aircraft systems. Adhering to these specifications demonstrates an understanding of safe practices in aircraft maintenance and enhances the reliability of the secured components.
