The Globe and Mail reports in its Thursday edition that Boeing said Wednesday it was shaking up the leadership in its commercial airplanes unit after a harrowing episode last month during which a piece fell off a 737 Max 9 jet in flight. A New York Times dispatch to The Globe says that Ed Clark, the head of Boeing's 737 Max program, which includes the Max 9, is leaving immediately. Boeing, which also announced other leadership changes, has been under pressure from regulators, airlines and members of Congress to prove that it is committed to making safe planes. Boeing said in recent weeks that it was overhauling its quality control process, including increased inspections at the factory in Renton, Wash., where Mr. Clark oversaw Max production. The leadership changes are the company's most prominent attempt to show it is holding itself accountable for the Jan. 5 episode that left a fuselage hole in an Alaska Airlines plane. Mr. Clark took over the Max program in 2021 as the company was accelerating production of the plane, which had been banned from flight worldwide for 20 months after two fatal crashes killed 346 people. Katie Ringgold, previously in charge of 737 deliveries, is taking over the Max program.
