Boeing is implementing changes to its quality control processes following an incident where a 737 Max 9 jet lost part of its body during an Alaska Airlines flight. The company will conduct additional inspections at its own factory and at the facility of a key supplier, Spirit AeroSystems. They will also invite airlines to conduct more inspections of the manufacturing process. An outside party will review the quality control program and suggest improvements. The Federal Aviation Administration has grounded all Max 9 planes and will expand its scrutiny of Boeing. The company is also inspecting the installation of door plugs at Spirit AeroSystems and has increased the number of quality inspectors by 20%. CEO Stan Deal emphasized the importance of adhering to the company's quality control standards.
