In aircraft leasing Life Limited Parts (LLPs) or Safe Life Items (SLIs) in aircraft are critical engine and airframe components with a predefined operational lifespan. SLI/LLPs are replaced after reaching their specified life limit based on flight hours, cycles, or age to ensure safety. Essentially after a defined period of usage for safety and compliance with aviation regulations the parts become scrap.
As an example as to the importance of Life Limited Parts (LLPs) and Safe Life Items (SLIs) we can focus on the significance and management of LLPs and SLIs in aircraft engines. These components, crucial for safety, have predetermined operational lifespans based on flight cycles, hours, or calendar time.
