What is the primary function of safety wire in aviation maintenance?

The primary function of safety wire in aviation maintenance is to secure fasteners and prevent them from loosening. In the aviation industry, ensuring that components remain securely fastened during operation is crucial for safety and reliability. Safety wire is used to create a secure connection between fasteners, adding an additional layer of security. When fasteners are tightened, safety wire is threaded through the heads of the fasteners and twisted to hold them in place effectively.

This process counters any chance of loosening that can occur due to vibrations or rotational forces experienced in flight. By employing safety wire, maintenance personnel enhance the integrity of the assembly, ensuring that critical components remain secure and function as intended throughout the aircraft's operational life.
