From the Wikipedia article

Delta Connection Flight 4819 was a scheduled international passenger flight from Minneapolis–Saint Paul International Airport in the United States to Toronto Pearson International Airport in Canada that crashed upon landing on February 17, 2025. The preliminary investigation determined that the aircraft experienced a hard landing that caused a landing gear component to fracture, leading to its collapse and the plane overturning on the runway. The aircraft was a Bombardier CRJ900 regional jet aircraft operated by Endeavor Air, a wholly owned subsidiary of Delta Air Lines. The flight had 80 people on board: 76 passengers and 4 crew members. While all occupants survived, 21 sustained injuries, and the plane was considered a hull loss.

Crash

The aircraft crashed upon landing on Runway 23 in Toronto Pearson International Airport at 2:13 p.m. EST (19:13 UTC) on February 17, 2025. The T-tail and right wing separated and ignited a fire, while the fuselage came to rest slightly off the right side of the runway, upside down, and facing the opposite direction from its landing. A passenger on the plane posted a video to social media showing the evacuation process and the overturned plane. 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. Fire crews sprayed water on the aircraft as a fire had briefly broken out on the fuselage while passengers were still evacuating.

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.

Emergency officials reported that 21 people were injured in the crash, suffering back sprains, head lacerations, and nausea from inhaling aviation fuel fumes. Among them, a child and two adults, a man in his 60s and a woman in her 40s, were critically injured. Three of the injured were transported to hospitals by air ambulance. According to Delta Air Lines, all 21 injured passengers were discharged from hospitals within four days, with the last release occurring on February 20.

Investigation and cause

Investigation

The Transportation Safety Board of Canada (TSB) sent over 20 investigators to begin investigating the crash. 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 Air Lines, and aircraft manufacturer Mitsubishi Aircraft Corporation (which purchased the CRJ programme from Bombardier in 2019). 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 laboratory for further analysis. Two of the airport's runways were closed to allow investigators to examine the wreckage and the runway.

On March 20, the TSB released its preliminary report. They found that 2.6 seconds before touchdown, the aircraft's rapid descent triggered the enhanced ground proximity warning system, which sounded a "sink rate" alert in the cockpit. Just before touchdown, the plane's airspeed was 136 kn and descending at 1100 ft/min. This was slower than the recommended landing speed (VRef) of 144 kn, and the rate of descent exceeded the landing gear's designed limit for absorbing impact, which is 720 ft/min. The weather at the time of the landing included gusty wind conditions. In such a situation, the pilot must keep a speed higher than the normal landing speed and carefully adjust engine power and plane attitude whenever a gust occurs.

As the aircraft's right main landing gear made contact with the runway, a part fractured, which caused the gear to collapse. After the collapse, the wing broke off from the fuselage. The detachment of the wing caused jet fuel to spill from the wing tank, which ignited. The TSB cautioned that the exact sequence of events is still under investigation.
