J. Michael Luttig, the former general counsel of Boeing until last May, who most recently was tasked with overseeing legal issues related to the 737 Max aircraft accidents of Lion Air Flight 610 and Ethiopian Airlines Flight 302, announced that he will retire after the CEO was forced out earlier this week.

“It has been an honor to serve as Boeing’s general counsel and as counselor and senior advisor to the Boeing board of directors,” Luttig, 65, said in a statement released Thursday.
