Cyclic abrupt rudder inputs can lead to which outcome?

Cyclic abrupt rudder inputs can lead to structural damage both above and below the maneuvering speed (VA). Maneuvering speed is an important limit in aircraft operation, as it represents the maximum speed at which full deflection of the control surfaces can be accomplished without risking structural damage.

When pilots apply abrupt rudder inputs, especially in high-stress situations or during extreme maneuvers, they can exceed the aircraft's designed limits even at speeds below VA. Rapid changes in yaw can create significant loads on the tail structure and the wings, potentially leading to structural failure. Additionally, at higher speeds (above VA), the risk of structural damage increases dramatically due to the greater forces experienced by the aircraft.

Thus, both scenarios ensure that cyclic abrupt rudder inputs can compromise the structural integrity of the aircraft, confirming that both potential outcomes are indeed correct.
