Boeing and the FAA have improved training and processes since 2024 incident, according to the NTSB, but board officials said both organizations need to better identify manufacturing risks.

After a year and half of investigating, the top U.S. aviation investigator formally determined that Boeing and its chief regulator were to blame for the Alaska Airlines blowout.

Boeing failed to provide adequate training, guidance and oversight to prevent a mid-air cabin panel blowout of a new 737 MAX 9 flight in January 2024 that spun the plane maker into a major crisis, the National Transportation Safety Board said on Tuesday (June 24).
