Southwest jet experiencing ‘Dutch roll’ left outside during severe storm.

A Southwest Airlines jet experienced an unusual “Dutch roll” in flight after undergoing routine maintenance following a strong storm while parked outside. The National Transportation Safety Board has not yet determined when the damage to the aircraft’s tail occurred. The Boeing 737 Max was grounded for over a month but has since resumed flights, with mechanics finding substantial damage in the rudder system.

Dutch roll is a combination of yaw and wingtip movements that can be dangerous, prompting modern planes to have a “yaw damper” to prevent such oscillations. The plane in question had fractures in the metal bracket and ribs holding a backup power control unit to the rudder system. While initial speculation was that the storm damage may have caused the issue, a former airline pilot and safety consultant believes it to be a one-off incident with no direct link to the Max or 737 models.

Southwest Airlines conducted inspections on all its Max jets and new planes, finding no other instances of damage around the rudder power units. The NTSB is continuing its investigation to determine the probable cause of the incident, with Southwest declining to comment on the matter. It may take a year or longer before a definitive conclusion is reached regarding the incident.
