When selecting hardware for bonding connections to an aircraft structure, which factors should be considered?

Selecting hardware for bonding connections to an aircraft structure involves several critical factors, among which ease of installation, mechanical strength, and current carrying capacity are paramount.

Ease of installation is crucial because bonding connections must be made efficiently and reliably to ensure the aircraft’s systems function properly. Complex or difficult installations can lead to mistakes or insufficient bonding, which may affect the electrical integrity of the aircraft.

Mechanical strength is essential as bonding connections need to withstand various physical stresses during operation. This includes vibration, thermal expansion, and possible impacts. The hardware must maintain a reliable connection without degrading under these conditions, which could lead to an increase in resistance and affect the performance of electrical systems.

Current carrying capacity is also a key consideration. Different electrical components and systems require specific levels of current, and the hardware used must be capable of safely carrying this current without overheating or failing. Insufficient current carrying capacity can pose risks of fire or electrical failure.

In summary, the combination of ease of installation, mechanical strength, and current carrying capacity ensures that the bonding connections are not only functional but also reliable and safe for use in aircraft systems.
