In a startling turn of events, United Airlines has discovered loose bolts on the door plugs of its Boeing 737 MAX 9 aircraft, causing further concerns about the safety of these planes. After Alaska Airlines recently experienced a harrowing incident in which a door plug blew off mid-flight, leaving a sizable hole in the cabin, United Airlines took immediate action to inspect their own fleet of planes. The Federal Aviation Administration (FAA) subsequently grounded approximately 171 Boeing 737 MAX 9 aircraft over the weekend.
According to United Airlines, inspections identified issues with the installation of door plugs, including bolts that required additional tightening. This revelation has raised questions about the manufacturing and maintenance processes of these aircraft models. However, the exact number of planes affected by this issue has not been disclosed.
