The Federal Aviation Administration (FAA) is investigating a depressurization incident involving a United Airlines Mitsubishi CRJ550. The aircraft, operated by GoJet Airlines on behalf of United Express, was forced to divert to Detroit Metropolitan Wayne County Airport on January 12 due to the issue.
According to the FAA, the flight crew of the CRJ550, registered as N545GJ, experienced depressurization problems while flying from Allentown Lehigh Valley International Airport to Chicago O'Hare International Airport. Flightradar24 data indicated that after departing Pennsylvania and climbing to 40,000 feet, the jet descended rapidly to 10,000 feet within seven minutes and then continued down to 6,000 feet before diverting. Despite the situation, no general emergency signal was sent during the flight. The aircraft landed safely in Detroit at 08:21 local time.
Following its diversion, GoJet Airlines relocated the plane to St. Louis Lambert International Airport later that day. During this transfer flight, it reached an altitude of 34,000 feet. The regional jet had scheduled flights from St. Louis to Washington Dulles International Airport and onward to Ottawa Macdonald-Cartier International Airport.
