CommutAir Flight 4933
CommutAir Flight 4933 (operating as United Express Flight 4933) was a domestic regional flight operating from Newark, New Jersey, to Presque Isle, Maine, in the United States. The flight was operated by CommutAir under the United Express brand. On March 4, 2019, the Embraer EMB-145XR operating the flight touched down in a snow-covered grassy area to the right of the runway at Presque Isle International Airport, injuring three aircraft occupants and substantially damaging the aircraft. The accident was attributed to confirmation bias which prompted the flight crew to continue descending even though they could not see the runway due to snow; poor decision-making by the captain, fatigue of the first officer, and problems with the airport's instrument landing system were identified as contributing factors. Background Aircraft The aircraft was a 14-year-old Embraer EMB-145XR first delivered to ExpressJet in October 2004, for Continental Express. From June 2007 to October 2008, the aircraft was operating for Delta Connection before operating once again for Continental Express until October 2010 when it commenced operations for United Express. In August 2016, the aircraft was transferred to CommutAir. Crew The aircraft had three crew members (two pilots and a flight attendant). The captain was 40-years-old and
