Boeing replaces head of troubled 737 Max program

Boeing is replacing the head of its 737 Max program, less than two months after a panel blew out on one of the jet models during an Alaska Airlines flight, prompting a federal grounding and heightened scrutiny of the plane maker's operations.

Ed Clark, who held that role, is leaving the company, Boeing Commercial Airplanes CEO Stan Deal said in a note to employees Wednesday. Katie Ringgold will step in as vice president and general manager of the 737 program and the company's Renton, Washington, site, Deal said.

"I am announcing several leadership changes as we continue driving BCA's enhanced focus on ensuring that every airplane we deliver meets or exceeds all quality and safety requirements. Our customers demand, and deserve, nothing less," Deal said.

"Ed departs with my, and our, deepest gratitude for his many significant contributions over nearly 18 years of dedicated service to Boeing," he added.
