A United Airlines Boeing 737-900ER aircraft was forced to return to Chicago O'Hare International Airport (ORD) on July 3, 2024, after experiencing cabin pressurization issues. The incident occurred during a scheduled flight from ORD to San Francisco International Airport (SFO).

The aircraft, performing flight UA 343, had been airborne for about an hour when the crew noticed the pressurization problem. The plane was climbing to FL250 when the issue was detected, prompting the crew to descend to 10,000 feet and return to ORD, landing safely on runway 27C.

The replacement aircraft reached SFO approximately three and a half hours later, completing the journey without further incident. The flight between ORD and SFO typically takes about four hours on a Boeing 737-900ER, according to Flightradar24.com.

The affected aircraft, registered as N69830, is one of United's fleet of 136 Boeing 737-900ERs. This particular jet, delivered in June 2014, is 10.1 years old.

The Federal Aviation Administration (FAA) has announced an investigation into the incident. The FAA stated, "United Airlines Flight 343 returned to and landed safely at Chicago O'Hare International Airport around noon local time on Wednesday, July 3, after the crew reported a pressurization issue. The FAA will investigate."

United Airlines has recently faced increased scrutiny from the FAA due to a series of safety incidents. Earlier this year, the FAA suspended some of United's certification activities and subjected the airline to heightened oversight. In May 2024, United announced it had been cleared by the FAA to resume certification activities, including launching new routes and certifying new aircraft. However, the FAA later clarified that it had not granted approval for network expansion and would require its personnel to be present during United's inspections of newly delivered aircraft.
