Should a lockwire be reused if it has been installed and then removed?

Lockwire, also known as safety wire, is designed for single-use to ensure the integrity and reliability of mechanical connections in aviation and aerospace applications. When lockwire is installed, it undergoes a level of stress and deformation that can compromise its structural integrity. Once removed, even if it appears to be in good condition, it may have microfractures or other damage not visible to the naked eye, which could lead to failure when reused.

Using new lockwire provides assurance that it will effectively prevent loosening of fasteners in critical applications. This practice enhances safety and reliability, particularly in high-stress environments such as aerospace assemblies, where failure of a component can have serious consequences. The best practice is to always use new lockwire to ensure the utmost safety and compliance with industry standards.
