What should be done in case of an uncommanded propeller feather?

In the case of an uncommanded propeller feather, following the emergency procedure checklist is essential for ensuring the safety of the aircraft and its occupants. An uncommanded propeller feather occurs when the propeller blade angle changes to a position that reduces thrust without pilot input, which can significantly impact aircraft performance and control.

The emergency procedure checklist provides a systematic approach to dealing with such critical situations. It includes specific steps to assess the situation, manage the aircraft's altitude and airspeed, and determine the next course of action, such as shutting down the affected engine or preparing for an emergency landing. Adhering to the checklist helps pilots respond effectively and minimize risk, as it is designed based on established protocols for handling emergencies.
