How often should you inspect thrust bearing nuts on new or overhauled engines?

Thrust bearing nuts on new or overhauled engines should be inspected every 150 hours of operation. This inspection frequency is established to ensure that the engine maintains its integrity and performance during operation. Regular checks are vital, particularly after overhaul, to catch any potential issues early that may arise from the settling of engine components or from the stress placed on these parts during initial operations.

Maintaining a consistent inspection schedule helps to prolong the life of the engine and ensures safety. The 150-hour interval strikes a balance between frequency and practicality, allowing for timely checks while not overburdening maintenance schedules. Other intervals, such as every 50, 100, or 200 hours, do not align with industry standards and best practices developed for monitoring thrust bearing conditions effectively.
