Part 5/7:
Scheduled maintenance also plays a significant role. After approximately 10,000 flight hours, engines may be completely replaced as part of routine checks and updates to ensure optimal performance. Mature engine designs that have been widely used often have undergone many rounds of updates based on widespread operational data, leading to increased reliability.
The physical process of replacing an aircraft engine requires specialized tools and a trained team. Aircraft are designed with predefined points for engine removal that are similar to how vehicles are lifted using jacks. This systematic approach streamlines replacement and aligns with safety and maintenance regulations that must be strictly followed.
