What is the importance of maintaining proper torque settings on fasteners?

Maintaining proper torque settings on fasteners is crucial for ensuring structural integrity and preventing failures. When fasteners—such as bolts, nuts, or screws—are tightened to the manufacturer's specified torque, they achieve a secure connection that holds components together under various operating conditions, including vibration, temperature fluctuations, and pressure changes.

If fasteners are under-tightened, they may not hold components securely, leading to loosening over time and potential failure of the assembly. On the other hand, over-tightening can cause damage to the fastener or the components being joined, which might result in cracking or deforming materials. Therefore, adhering to torque specifications is essential in aviation maintenance, where safety and reliability are paramount.

This focus on structural integrity directly aligns with the safety standards required in aviation, where any failure due to improper fastener torque could have severe consequences. Proper torque settings ensure that the loads and stresses experienced during operation are appropriately managed, helping avoid accidents and ensuring the longevity of aircraft components.
