An emergency airworthiness directive requires US Boeing 737 operators to adopt new procedures to improve pilots' control following sudden uncommanded rudder movements. The new procedures, to be included in the 737 flight manual, also outline actions to deal with a jammed or restricted rudder. Pilots are advised to lower the nose to increase airspeed, disconnect the autopilot and autothrottle, and to give priority to assuring control of the aircraft rather than to maintaining an assigned altitude.
