(Reuters) - 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.
