Boeing Co. said Dec. 26 that J. Michael Luttig, counselor and senior advisor to the company's board, will retire by the end of 2019.

Since May 2019, Luttig has been managing legal matters stemming from two fatal crashes involving Boeing's 737 MAX airplane, which is indefinitely grounded around the world. The company will suspend production of the model beginning January 2020.

Luttig previously served as Boeing's general counsel.

Luttig's retirement comes a few days after the Boeing board ousted CEO Dennis Muilenburg in a bid to restore public confidence in the company, which has struggled to cope with the fallout of the 737 MAX grounding.
