Which consequence results when a fly-by-wire flight control hydraulic actuator seal degrades?

💡 Explanation

Uncommanded control surface deflections occur because internal leakage within the actuator allows the flight control surface position to deviate from pilot command, rather than causing increased drag—due to minor changes—or structural fatigue, therefore destabilizing the aircraft.
