(TORONTO) –Investigators probing Monday afternoon’s Delta Flight 4819 plane crash at Toronto Pearson International Airport are piecing together what caused the dramatic incident, sources told ABC News.
The Delta regional jet — a CRJ 900 aircraft operated by Endeavor Air — originated in Minneapolis. The aircraft was left lying upside-down and ablaze on the snow covered Toronto runway after the crash, with its 76 passengers and four crew evacuated, according to Delta and the Federal Aviation Administration.
Toronto Pearson President and CEO Deborah Flint confirmed there were no fatalities, commending the “heroic and trained professionals” who responded to the crash. There were 22 Canadian citizens among the passengers, Flint said.
Twenty-one passengers were taken to hospitals, and as of Tuesday morning, 19 of them have been released, according to Delta.
Peel Regional Paramedic Services said none of the injuries were considered life-threatening.
Three people suffered critical injuries: one child, a man in his 60s and a woman in her 40s, according to medical transport organization Ornge.
What caused the plane to flip and catch fire was not immediately clear. Sources told ABC News on Monday that the investigation was already underway.
The Transportation Safety Board of Canada will lead the investigation and investigators from the FAA and National Transportation Safety Board are assisting.
The Toronto Airport temporarily stopped flights in the wake of the crash, with departures and arrivals resuming at 5 p.m. ET Monday, the airport said. Two runways remained closed, which Flint said may impact operations.
“Our most pressing priority remains taking care of all customers and Endeavor crew members who were involved,” Delta CEO Ed Bastian said. “We’ll do everything we can to support them and their families in the days ahead, and I know the hearts, thoughts and prayers of the entire Delta community are with them. We are grateful for all the first responders and medical teams who have been caring for them.”
The crash occurred during blowing snow and strong wind gusts in the region. Winds reached 40 mph on the ground and were even stronger several hundred feet in the air.
Toronto Airport Fire Chief Todd Aitken said the runway was dry and there were no crosswind conditions at the time of the crash.
