What is the propeller RPM overspeed limit?

The propeller RPM overspeed limit for the King Air 350 is set at 1768 RPM. This specification is crucial for maintaining the integrity of the propeller and ensuring safe operation of the aircraft. Exceeding this RPM can lead to damaging stress on the propeller blades and associated mechanisms due to the forces generated at higher speeds. For pilots operating the King Air 350, understanding this limit is essential not only for compliance with operational procedures but also for ensuring the safety and longevity of the aircraft's propeller system. The other options represent RPM values that exceed the established limit, which would put the aircraft at risk of mechanical failure if reached during flight.
