Which of the following is true regarding structural hardware installation?

The correct answer emphasizes the importance of matching component specifications when installing structural hardware. This practice is crucial because different hardware components—such as bolts, nuts, and washers—have specific material properties, sizes, and strengths that must align with the requirements of the aircraft structure. Using the correct specifications ensures the hardware can withstand the loads and stresses encountered during operation, thus maintaining the integrity and safety of the aircraft.

In aviation, discrepancies in hardware specifications can lead to serious structural failures. Therefore, following the appropriate guidelines and standards when selecting and installing hardware is vital for reliability and safety. This aspect of installation is not only about adhering to manufacturer's recommendations but also encompasses regulatory compliance and thorough understanding of the aircraft's operational environment.
