What is the main goal of "Preventive Maintenance"?

The main goal of "Preventive Maintenance" is to detect and correct issues before failures occur. This proactive approach aims to maintain the functionality and safety of aircraft systems by regularly inspecting, servicing, and replacing components as needed. By identifying and addressing potential problems early, preventive maintenance helps in avoiding unexpected breakdowns, costly repairs, and safety hazards, thereby enhancing aircraft reliability and performance.

In the context of aviation maintenance, this practice is critical since it supports the overall safety and airworthiness of aircraft, ensuring that they can perform optimally during operations. Other options, such as performing repairs only after failures occur, are contrary to the essence of preventive maintenance, which is focused on preemptive action rather than reactive measures. Additionally, while ensuring safe operations and training personnel are important aspects of maintenance and operational efficiency, they do not capture the primary preventive aspect of maintenance aimed at issue detection and correction.
