On the 28th, the Federal Aviation Administration of the United States requested Boeing to develop a comprehensive action plan within 90 days to address its "systemic quality control issues" in a statement.
The statement states that the plan must include the latest investigation results of the upcoming production line audit and expert review panel report to be released by the Federal Aviation Administration; The plan must include the steps that Boeing will take to improve its "security management system" plan; Boeing must also integrate this plan with its quality management system to ensure that equally strict control and supervision standards are applied to its suppliers, and to establish a measurable and systematic transformation in production quality control.
According to the statement, Federal Aviation Administration Director Mike Whittaker stated after meeting with Boeing President and CEO Dave Calhoun that Boeing must be committed to true and profound improvement, and achieving fundamental change requires sustained efforts from Boeing leadership.
Whittaker also stated, "Boeing must re-examine all aspects of its quality control process and ensure that safety is the company's guiding principle."
Calhoun responded to a statement from the Federal Aviation Administration on the same day, stating that Boeing will develop a comprehensive action plan with measurable standards to respond to the requirements of the Federal Aviation Administration.
On January 5th, an accident occurred shortly after takeoff on an Alaska Airlines Boeing 737 MAX 9 aircraft, with a door stopper on the side of the cabin falling off. After inspection by investigators, it was found that four bolts that were supposed to fix the door plug in place were missing. The accident occurred only about two months after the aircraft was delivered to Alaska Airlines.
