The Chicago-based aircraft maker said Arthur Collins Jr., chairman of the committee that sets executive compensation, and Susan Schwab won''t stand for reelection at Boeing''s annual shareholder meeting in April.

Boeing directors and executives were named in a shareholder lawsuit filed in a Delaware court that alleges the board failed to properly oversee management during engineering problems with the 737 Max. The plane was grounded for 20 months after two crashes that killed 346 people. The crisis has cost Boeing billions.

Last month, former KPMG CEO Lynne Doughtie replaced Caroline Kennedy, daughter of President John F. Kennedy, on the board. In 2020, two new directors joined, and the board created a safety committee. The year before that, CEO Dennis Muilenburg was ousted and replaced by David Calhoun, who had been board chairman.

Collins is a former CEO of medical-device maker Medtronic Inc. Schwab was U.S. trade representative under President George W. Bush.

Boeing did not announce nominees to replace them.
