A Southwest jet that did a ‘Dutch roll’ was parked outside during severe storm

SUMMARY

Investigators have disclosed that a Southwest Airlines Boeing 737 Max experienced an unusual "Dutch roll" in flight after being parked outside during severe weather and undergoing routine maintenance. The incident occurred during a flight from Phoenix to Oakland, with pilots noting erratic movements of the rudder pedals at high altitudes. Subsequent inspection revealed significant damage to the aircraft's tail section, specifically around the rudder system. Although the cause of the damage has not yet been pinpointed, initial findings suggest it may have occurred during a thunderstorm where the plane was parked, rather than being linked to the Dutch roll or recent maintenance. Southwest Airlines has since resumed flights of the aircraft after inspections found no similar issues in their fleet. The National Transportation Safety Board continues its investigation to determine the exact cause of the incident, which could take over a year to conclude.
