Which publication details mandatory replacement times for parts of a turbine engine?

The Engine Manufacturer's service instructions are crucial documents that provide detailed information on the maintenance, operation, and repair of turbine engines. These instructions include specific guidelines for various components, including mandatory replacement times for parts, which are essential for maintaining the engine's safety and efficiency. This information is vital for ensuring compliance with safety regulations and maximizing the engine's service life.

By following the manufacturer’s recommendations outlined in the service instructions, maintenance personnel can effectively manage the lifecycle of engine components, ensuring timely replacements to prevent failures and enhance operational reliability. This is particularly important in aviation, where safety is paramount and compliance with established protocols can save lives.

In contrast, other options do not serve the same purpose. The Airplane Flight Manual primarily focuses on operating procedures and limitations of the aircraft, while logbook records are documentation of maintenance performed but do not specify replacement times. Technical Standard Orders pertain to technical specifications for materials and hardware, not specifically to maintenance schedules for turbine engines.
