WASHINGTON, Oct 8 (Reuters) - The Federal Aviation

Administration on Tuesday issued a safety alert to airlines

warning of the potential for limited or jammed rudder movement

on certain Boeing 737 airplanes.

Last week, the National Transportation Safety Board said

more than 40 foreign operators of Boeing 737 airplanes

may be using MAX or 737 Next Generation planes with rudder

components that could pose safety risks.

The board on Sept. 26 issued urgent safety recommendations

and urged the FAA to take action over the potential for a jammed

rudder control system on some 737 airplanes after a February

incident involving a United Airlines flight.
