Delta Connection Flight 4819 was a scheduled international passenger flight from Minneapolis–Saint Paul International Airport, United States, that crashed and overturned on the runway when landing at Toronto Pearson International Airport, Canada, on a routine flight on February 17, 2025. The aircraft was a Bombardier CRJ900 regional jet aircraft operated by Endeavor Air, a wholly owned subsidiary of Delta Air Lines.^[a]

The flight had 80 people on board, consisting of 76 passengers and 4 crew members. All passengers and crew survived, but 21 injuries were reported.

The aircraft involved was a 16-year-old Bombardier CRJ900LR, assembled in 2008 and powered by two General Electric CF34-8C5 turbofan engines. It bore the Manufacturer's serial number 15194 and was registered as N932XJ.^[1][2]

The CRJ900LR is a variant of the CRJ900 series of regional jets produced by Bombardier, modified to operate longer-range flights enabled by a higher maximum takeoff weight (MTOW) as compared to the base variant of the CRJ900, a jet commonly used to operate short- to medium-haul regional flights.^[3][4][5] Delta configures the CRJ900 with seating for up to 76 passengers.^[6]

The crash was the second hull loss involving a Bombardier CRJ-700 series aircraft in 2025, following the Potomac River mid-air collision near Washington Reagan National Airport in late January.^[7]

The flight had 80 people on board, four crew members and a full load of 76 passengers, of whom, 22 were Canadian nationals.^[8] The crew comprised a captain, a first officer, and two flight attendants.^[9]

Delta said the pilots were experienced and familiar with flying in wintry conditions.^[10]

At the time of the crash, there was blowing snow following a winter storm the previous weekend, with winds out of the west at 51 kilometres per hour (32 mph; 28 kn), gusting up to 64 kilometres per hour (40 mph; 35 kn) and a temperature of about −8.6 °C (16.5 °F) were present at the airport.^[11][12][13]

Before the crash, air traffic controllers warned the pilots of a possible air flow bump along the approach during landing.^[14]

The aircraft crashed upon landing at the threshold of Runway 23 in Toronto Pearson International Airport at 2:13 p.m. EST (19:13 UTC), the tailfin and one wing separated and ignited a fire,^[15] while the fuselage came to rest slightly off the right side of the runway, upside down, and facing the opposite direction from its landing.^[16][17] A passenger on the plane posted a video to social media showing the evacuation process and the overturned plane.^[18]

Video taken from an aircraft awaiting takeoff showed Flight 4819 slamming into the ground as it landed, bouncing and sliding forward in a roll to the right. The airplane's right wing sheared off before it came to rest on its back with flames emerging from the fuselage.^[19] Other videos show the inverted plane with its right wing missing and its vertical fin torn off.^[15] Smoke was seen from the fuselage.^[20]

Aviation safety experts said that the flight attendants and the design of the aircraft played an important role in the relative safety of the passengers in the crash. Videos shared online showed the flight attendants working to quickly evacuate everyone from the aircraft.^[21]

Emergency officials reported that 21 people were injured in the crash,^[18][22][23] suffering back sprains, head lacerations, and nausea from inhaling aviation fuel fumes.^[24] Among them, a child and two adults—a man in his 60s and a woman in her 40s—were in critical condition,^[25][26] though none of the injuries were life-threatening.^[27] Three of the injured were transported to hospitals via air ambulance.^[14] According to Delta Airlines, all 21 injured passengers were discharged from hospitals within four days, with the last release occurring on February 20.^[22]

The airport halted all take-offs and landings until 5:00 p.m. EST, when the airport resumed departing and arriving traffic.^[8][18] Montréal–Trudeau International Airport, Ottawa Macdonald–Cartier International Airport and John C. Munro Hamilton International Airport began accepting diverted flights following the incident.^[13][28][29] Delta Air Lines offered US$30,000 in compensation to each passenger aboard the plane, adding that the offer had "no strings attached" and did not affect their future legal rights.^[30]

The Transportation Safety Board of Canada (TSB) sent over 20 investigators to begin looking into the crash.^[16] To support the investigation, representatives were sent from Transport Canada, the U.S. National Transportation Safety Board, the U.S. Federal Aviation Administration, Endeavor Air, Delta Airlines, and aircraft manufacturer Mitsubishi Aircraft Corporation (which purchased the CRJ programme from Bombardier in 2019).^{[2][16][14][31]} On February 18, investigators said they had retrieved the cockpit voice recorder and the flight data recorder (also known as the "black boxes") and sent them to a TSB lab for further analysis.^[16][32] Two of the airport's runways were closed to allow investigators to examine the wreckage and the runway.^[16][33]
