Amid a federal investigation into what caused a door plug to blow off a Boeing 737 Max 9 jet in January, a Boeing top official said the company cannot find documents about the door plug and it's likely that such records never existed.
Ziad Ojakli, the executive vice president of government operations at Boeing, said employees looked "extensively" and failed to turn up any paperwork about the "opening and closing of the door plug," he said in a letter to Washington Sen. Maria Cantwell on Friday.
According to Ojakli, Boeing's working hypothesis is that "the documents required by our processes were not created when the door plug was opened."
