What is the significance of using safety wire on fasteners?

• A. It enhances the aesthetic appearance of the aircraft
• B. It connects electrical components
• C. It prevents fasteners from loosening during operation
• D. It reduces the weight of the aircraft

Answer: (C)

Using safety wire on fasteners is crucial in the aviation industry because it serves the primary purpose of preventing fasteners from loosening during operation. In an aircraft, vibrations and dynamic forces can cause fasteners — such as bolts and nuts — to become loose over time. Safety wire is installed in a way that it secures these fasteners tightly and ensures they cannot unintentionally unscrew or move during flight or when the aircraft is in operation. This practice enhances the safety and reliability of the aircraft. If fasteners were to loosen, it could lead to critical components coming undone, potentially resulting in mechanical failure. Therefore, applying safety wire adds an additional layer of security against mechanical failure due to loosened fasteners. The other options do not align with the primary function of safety wire. While aesthetics may have some importance in the overall design of the aircraft, they are not relevant to the functional purpose of safety wire. Connecting electrical components is a different focus altogether and does not relate to fasteners. Reducing the weight of the aircraft is an important consideration in aircraft design, but safety wire is not specifically used for that purpose; rather, it is used for securing fasteners against loosening.
