FAA Issues Safety Alert for Boeing 737 Rudder Malfunction

The alert follows investigations into potential rudder jams affecting certain Boeing 737 models, urging pilots to review response procedures.

The FAA has issued a safety alert warning about potential rudder movement restrictions on some Boeing 737 aircraft, including the 737 Max and Next Generation models.
The alert comes after a February incident where a United Airlines 737 experienced jammed rudder pedals during landing, prompting an NTSB investigation.
Investigations revealed that moisture accumulation in actuators, due to improperly assembled sealed bearings, can freeze and limit rudder movement.
Over 353 affected actuators have been identified, impacting both U.S. and international operators, with Boeing working under regulatory oversight to address the issue.
The FAA advises pilots to follow Boeing's non-normal checklist for jammed controls and will notify international aviation agencies about the rudder actuator concerns.
