On February 17, 2025, Delta Connection Flight 4819, operated by Endeavor Air, experienced a severe landing accident at Toronto Pearson International Airport. The Bombardier CRJ900LR, en route from Minneapolis–Saint Paul International Airport, carried 80 individuals—76 passengers and four crew members. Upon landing, the aircraft flipped and came to rest inverted on the runway. Remarkably, all occupants survived, though 21 sustained injuries, including three critical cases: a child and two adults. Emergency responders promptly transported the injured to local hospitals.



The incident occurred amid challenging weather conditions, with blowing snow and winds gusting up to 64 km/h. The Transportation Safety Board of Canada has initiated an investigation, with assistance from the U.S. National Transportation Safety Board. Preliminary findings indicate that the aircraft's left elevator became jammed in a fully upward position during pre-flight checks, leading to uncontrollable pitch-up movements during landing. This mechanical failure is suspected to have contributed significantly to the accident.

In response to the crash, Toronto Pearson International Airport temporarily suspended operations, diverting incoming flights to nearby airports. The runway remained closed for several hours as investigators examined the scene and retrieved the flight data recorder for analysis. Delta Air Lines has expressed gratitude for the swift actions of the emergency personnel and is cooperating fully with the ongoing investigation.

This event marks the second major aviation incident involving a Bombardier CRJ series aircraft in 2025, following a mid-air collision near Washington Reagan National Airport in late January. The aviation community awaits further details from the investigation to understand the precise causes and to implement measures to prevent similar occurrences in the future.
