What maintenance actions are typically performed on the propeller of the Pilatus PC-12 NG?

The maintenance actions for the propeller of the Pilatus PC-12 NG primarily include regular inspections and overhauls in accordance with the manufacturer's guidelines. These are critical for ensuring the propeller's operational integrity and performance. Regular inspections help identify any wear or damage that may have occurred since the last check, while overhauls are necessary to address any significant issues and refresh the propeller to safe operational status. Following manufacturer guidelines is essential in aviation, as these documents provide specific protocols and intervals for maintenance based on extensive testing and regulatory standards, ensuring both safety and performance.

Other options indicate lesser or incorrect maintenance practices. For instance, complete replacement every 1000 hours would be unnecessarily excessive and not in line with standard practices, as most propellers can last much longer with proper maintenance. Only doing oil changes without additional inspections does not adequately address the various stressors and potential wear that a propeller can experience. Visual checks before every flight are important but are only a part of the overall maintenance strategy and should not replace the need for comprehensive inspections and overhauls.
