How a regional jet survived an upside-down landing at Toronto Pearson International Airport
In short: On February 17, 2025, Delta Connection Flight 4819 crashed upon landing in Toronto, flipping completely over on the runway. Despite the aircraft becoming a total hull loss and a fire breaking out, all 80 people on board survived. Investigators are now analyzing why this routine flight ended in disaster.
The aircraft, a 16-year-old Bombardier CRJ900 operated by Endeavor Air, was arriving from Minneapolis–Saint Paul when it encountered gusty conditions. According to the Transportation Safety Board of Canada's preliminary report, the plane was descending at 1,100 feet per minute—significantly faster than the landing gear's structural limit of 720 feet per minute. Furthermore, the aircraft's airspeed of 136 knots was below the recommended landing speed of 144 knots. These factors, combined with the challenging weather, led to a hard landing that fractured a landing gear component.
Upon the gear's collapse, the right wing detached from the fuselage, causing a fuel spill that ignited. The plane eventually came to rest upside down, facing the opposite direction of its approach. While the incident resulted in 21 injuries, including three critical cases, the rapid evacuation led by the flight attendants was credited by safety experts as a vital factor in the survival of all occupants. All injured passengers were discharged from hospitals within four days of the event.
The investigation, involving over 20 TSB investigators and representatives from the U.S. National Transportation Safety Board and the Federal Aviation Administration, is ongoing. The cockpit voice and flight data recorders were recovered the day after the crash. While Delta Air Lines faced public scrutiny regarding the pilots' experience, the company clarified that both crew members exceeded federal requirements and were fully certified. The flight captain, who was monitoring the landing, had 3,570 total flight hours, while the first officer, who was flying, had 1,422 hours.
This crash joins a rare category of aviation accidents where aircraft have come to rest inverted, such as incidents involving McDonnell Douglas MD-11s. The TSB continues to examine the wreckage and runway conditions to determine the exact sequence of events. In the aftermath, Delta Air Lines provided US$30,000 in compensation to each passenger, emphasizing that the payment did not affect their legal rights.
