NTSB issues urgent safety recommendations on Boeing 737 rudder after Newark incident

The National Transportation Safety Board on Thursday issued urgent safety recommendations about the potential for a jammed rudder control system on some Boeing 737 airplanes after a February incident involving a United Airlines flight. The NTSB is investigating an incident in which the rudder pedals on a United Boeing 737 MAX 8 were "stuck" in the neutral position during a landing at Newark. United said the rudder control parts at issue were in use in only nine of its 737 aircraft originally built for other airlines.
