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.

Boeing will be back in the hot seat Tuesday as the National Transportation Safety Board holds a hearing to present its findings from an investigation into the terrifying incident in which a door plug blew out of an Alaska Airlines 737 Max.

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.
