How frequently should thrust bearing nut checks be conducted after the initial inspection?

The correct frequency for thrust bearing nut checks after the initial inspection is established as every 100 hours. This requirement is rooted in maintenance practices designed to ensure the safety and reliability of aircraft operations. After the initial inspection, conducting these checks at intervals of 100 hours helps to monitor the integrity of the thrust bearing nuts, which play a crucial role in supporting the engine and relating components during operation.

Regular checks at this interval help identify potential issues early, allowing for timely maintenance and preventing more significant problems that could arise from overlooked wear or loosening. This practice is critical, as the thrust bearings undergo substantial stress and loads during flight, making diligent oversight essential for the continued airworthiness of the aircraft.
