Which term describes missing or damaged connector contacts?

The correct answer reflects the need to understand the significance of maintaining the physical components of connectors in aircraft systems. Mechanical integrity specifically refers to the structural soundness and physical condition of components, including connector contacts. When contacts are missing or damaged, it compromises the mechanical integrity, potentially leading to failures in electrical connection and overall system performance.

The other terms relate to different aspects of connectors. Electrical continuity focuses on the flow of electrical current through a circuit; while crucial, it does not specifically address the physical condition of the contacts themselves. Connector reliability pertains to the overall performance and dependability of the connector over time but does not address the specific issue of missing or damaged contacts directly. Wiring integrity encompasses the proper functioning and security of the entire wiring system, but again, does not directly refer to the contacts within connectors. Thus, mechanical integrity is the most appropriate term to describe the state of missing or damaged connector contacts.
