Head of Boeing's 737 Max program departs, amid problems related to the aircraft

Boeing announced Wednesday that Ed Clark, the leader of U.S. aircraft manufacturer's 737 Max program is leaving the company, amid problems with the craft.

The announcement was made by CEO Stanley Deal, who said Clark's departure was part of a larger leadership change. 

“Ed departs with my, and our, deepest gratitude for his many significant contributions over nearly 18 years of dedicated service to Boeing,” Deal said, according to NBC News. 

The company is facing multiple investigations over problems with the 737 Max craft, starting with a Jan. 5 incident in which a door panel or "plug" on a 737 Max 9 craft for Alaska Airlines became detached midair from the fuselage.
