NTSB Blames Missed Inspections for Southwest Dutch Roll (simpleflying.com)

A Southwest Airlines Boeing 737 MAX flew 44 times with undetected storm damage before experiencing a Dutch roll accident on May 25, 2024. The NTSB determined that high winds in New Orleans damaged the standby rudder power control unit, but maintenance oversights and a flawed inspection test allowed the aircraft to remain in service. Following the incident, Boeing and Southwest established new 65-knot wind thresholds to trigger mandatory inspections.
