Which type of part has priority for due dates in maintenance?

Life Limited Parts have priority for due dates in maintenance due to their critical role in ensuring the safety and reliability of equipment. These components are subject to strict limitations on their usage based on time, operational cycles, or other factors, which are defined by manufacturers to prevent failures that could result in catastrophic consequences. The life-limited status necessitates that these parts be replaced or serviced before reaching their defined limits, ensuring that they perform effectively throughout their operational lifecycle.

In comparison, while emergency replacement parts and engine components are also important, they do not carry the same stringent replacement requirements tied specifically to time or usage limits. General spare parts, while crucial for maintaining operational efficiency, are managed with more flexibility and do not prioritize due dates in the same way that life limited parts do. Hence, the urgency associated with life limited parts directly influences maintenance scheduling and prioritization.
