True or False: A good use of lockwire is indicated by how much wire is left beyond the fastener after trimming.

Lockwire, also known as safety wire, is a critical component in aerospace maintenance to prevent fasteners from loosening due to vibration and movement. The correct use of lockwire involves ensuring that it is not only twisted properly but also trimmed appropriately to provide the necessary security without the risk of interference or damage.

When using lockwire, the amount of wire left beyond the fastener after trimming is a critical consideration. Ideally, there should be a small amount of wire left after trimming to ensure that the lockwire is securing the fastener effectively. If too little wire is left, it may compromise the effectiveness of the safety feature, while too much excess wire could create a safety hazard by getting entangled in moving parts or causing damage.

Thus, a good use of lockwire is indeed indicated by how much wire is left beyond the fastener after trimming, as this reflects proper installation techniques and attention to detail in maintaining the integrity of the assembly.
