Boeing Co.’s board will add a director with safety expertise and adopt other internal measures under a proposed $237.5 million agreement to settle a shareholder lawsuit that alleged lax board oversight led to the 737 MAX disasters.

According to a proposed settlement filed Friday in Delaware’s Court of Chancery, the plane maker has agreed to add another director to its 12-member board with aviation, engineering or product-safety oversight experience. Boeing also agreed to ensure at least three directors have such expertise. The company earlier this year added to the board a former airline pilot and a former executive from an engine-maker.
