NTSB conducting new interviews with Boeing on 737 MAX 9 door plug probe

The NTSB is conducting a new round of interviews with Boeing and FAA personnel this week in its probe of the January Alaska Airlines 737 MAX 9 in-flight emergency. NTSB Chair Jennifer Homendy on Wednesday said investigators were back at the 737 plant in Renton, Washington, this week for more interviews. "We are looking at other instances where a door plug was opened and closed to make sure that those records are available," Homendy said at a U.S. Senate hearing, saying investigators want to make sure those other instances were documented. Boeing, whose shares fell 2% on Wednesday, declined to comment on the interviews. Last month, Boeing said it believed that required documents detailing the removal of the door plug in the Alaska Airlines plane involved in the emergency were never created. Homendy said on Wednesday that Boeing and investigators still do not know the personnel who worked on the Alaska Boeing 737 MAX 9 that suffered the emergency. "This work occurred in September. They move a lot of planes through that factory," Homendy said. "The biggest concern is missing records." At issue is the process not the individuals, she said. "This isn't a gotcha on anybody," Homendy said, adding the NTSB has still been unable to interview the door plug team manager, who has been on sick leave.<br/>
