"Boeing's Record-Keeping Woes: NTSB Investigates 737 MAX 9 and Alaska Airlines Incidents"

Boeing states that it has not found any documents detailing the removal of a key part during the production of a 737 MAX 9 that failed during a mid-air emergency, leading to criticism from the NTSB for lack of cooperation and failure to disclose documents and employee names. The incident prompted the FAA to ground the MAX 9, halt production rate increases, and order Boeing to address systemic quality-control issues. Boeing claims it was not aware of any complaints about lack of collaboration and is committed to cooperating fully with the NTSB's investigation.
