After installation, what is a jo-bolt considered to be?

A jo-bolt is considered a permanent part of the aircraft structure after installation. Unlike temporary fasteners that can be easily removed and replaced, jo-bolts are designed to provide a long-lasting and robust connection within the airframe. Their primary function is to secure structural components in a way that can endure the operational stresses encountered during flight. This permanence is crucial for maintaining the integrity and safety of the aircraft.

Understanding the role of jo-bolts within the aircraft's structure emphasizes the importance of proper installation procedures and ongoing maintenance. Since they are intended to remain in place throughout the lifespan of the aircraft, the correct material and torque requirements must be adhered to when they are installed to ensure the reliability of the connection under various operational conditions. This knowledge is vital for anyone working as an Aviation Structural Mechanic, as the safety and performance of the aircraft depend significantly on the integrity of these structural fasteners.
