Emergency landing of another plane after receiving alert of door opening, United Airlines told this

An official from United Airlines stated that the emergency landing this afternoon was done out of caution to address a potential mechanical issue. The representative did not clarify if the problem was because of the open door. According to a spokesman for the Tampa airport, the pilots had stated as much when they asked for the landing.

Less than a week has passed since a serious problem occurred on an Alaska Airlines Boeing 737 Max 9 when an emergency door opened as the aircraft was travelling from Portland, Oregon, to Honolulu, Hawaii. At 16,000 feet, the door broke out, causing a sizable hole in the side of the aircraft and a sharp loss in air pressure for the occupants.

Six members of the crew and 171 passengers were on Alaska Airlines Flight 1282. Thankfully, no passengers were gravely hurt in the plane's emergency landing at Seattle-Tacoma International Airport. Before all Boeing 737 Max 9 aircraft resume flying, the Federal Aviation Administration (FAA) has requested an inspection of the cabin door exit plugs, door components, and fasteners.

United Airlines and Alaska Airlines are the only two US carriers that operate this model of aircraft. Both airlines have reported finding loose hardware on some of their Max 9 aircraft.
