How many inches should the end of the twisted wire protrude beyond the center of the first bolt when cutting lockwire?

The correct answer indicates that the end of the twisted wire should protrude two inches beyond the center of the first bolt when cutting lockwire. This length is necessary for several reasons, particularly in ensuring a proper grip and securing fasteners effectively. A two-inch tail provides enough wire to secure without excessive slack, which can lead to failure in securing components due to vibration or movement in high-performance applications.

Moreover, having an adequate length helps in the twist and securing the wire around the bolt heads properly. It allows for adjustments and ensures that the tail can be maintained in a way that it does not interfere with any moving parts or create potential hazards. A tail that is too short may not provide adequate securing, while a longer tail might complicate the installation or create clutter, which is not ideal in aerospace applications where precision and reliability are paramount.
