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.
Overview
- 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.
