In the aftermath of the incident, which caused no injuries, the Federal Aviation Administration grounded the MAX 9 for several weeks in January, barred Boeing from increasing the MAX production rate and ordered Boeing to develop a comprehensive plan to address "systemic quality-control issues" within 90 days. Boeing's letter said, "It appears from our records this list was requested from us for the first time on Saturday, March 2, by email, and the request was discussed by Boeing and the NTSB on Monday." Homendy said on Wednesday the NTSB had been trying for two months to identify the specific MAX 9 production shift and employees, adding the board had told key lawmakers about its request for employee names during a Feb. 6 meeting.
