"Boeing's Quality Control Under Scrutiny: FAA Chief Vows Expansion of Probe"

The FAA has deployed inspectors to Boeing's 737 Max factory to visually inspect aircraft and ensure the manufacturer's quality control system is functioning properly following an incident where a door plug blew out on an Alaska Airlines flight. The FAA is working with Boeing and airlines on inspection instructions for the 737 Max 9's return to service, but the timeline remains uncertain. United Airlines is assuming the planes will remain grounded through the end of January, and Boeing is pausing production lines for safety sessions to address the issue. The FAA is considering potential changes to its oversight of Boeing's production processes.
