What publication contains the mandatory replacement time for turbine engine parts?

The correct choice is the Engine Manufacturer's Maintenance Manual, as it serves as the authoritative source for maintenance practices specific to a particular engine model. This manual is published by the engine manufacturer and outlines critical maintenance information, including specifications for mandatory replacement times for various turbine engine parts.

Unlike other options, such as the FAA Maintenance Handbook, which provides general guidelines and practices, and the Aircraft Performance Manual, which focuses on the aircraft's operational capabilities and performance metrics, the Engine Manufacturer's Maintenance Manual is specifically designed to address the unique requirements and recommendations for maintaining a specific engine type. Similarly, the Engine Regulations Handbook covers broader regulatory requirements but does not typically provide the detailed and specific replacement times that are essential for safe and effective engine maintenance.

The Engine Manufacturer's Maintenance Manual is tailored to ensure compliance with safety and operational standards set by the manufacturer, thereby safeguarding the performance and reliability of the engine throughout its lifecycle.
