NTSB: Missed Inspections Let Storm-Damaged Southwest 737 MAX Fly 44 Times Before Dutch Roll Accident
xCruzo Brief
A National Transportation Safety Board (NTSB) report on a May 2024 crash concludes that storm damage to a Southwest Boeing 737 MAX went undetected for nine days and 44 flights after the aircraft missed a post-storm inspection. The NTSB said severe winds damaged the standby rudder power control unit (PCU) mounting structure and its connection to the vertical stabilizer at Louis Armstrong New Orleans International Airport (MSY) on May 16. No external damage was obvious and no inspection was conducted. The jet later experienced a Dutch roll on May 25 on Southwest flight 746 from Phoenix (PHX) to Oakland (OAK), landing safely. Investigators also cited an incorrectly signed maintenance test in Houston.
