Which of the following is NOT a reason for using Clecos during assembly?

The use of Clecos in aerospace assembly is primarily for temporary fastening and alignment during the assembly process. Clecos are clips that can hold pieces together securely while additional work is carried out, such as drilling or riveting. They are particularly useful for ensuring that components are properly aligned before applying permanent fasteners.

Securing panels temporarily is essential since it allows mechanics to adjust and ensure proper fit before committing to the final assembly process. Clecos also serve as indicators for fully drilled holes by providing a visual cue that a specific area is ready for further fastening operations. Additionally, they facilitate the alignment of components which is crucial to maintain the integrity and design specifications of the assembly.

The key point here is that Clecos are not intended to provide permanent fastening. Their design and function are suited exclusively for temporary applications, making them valuable during the assembly process but inappropriate as a long-term fastening solution. This distinction clarifies why the role of Clecos is limited to temporary assembly tasks rather than serving as a permanent fastening mechanism.
