Feb 19 (V7N) – Canadian investigators have begun analyzing the black boxes from the Delta Air Lines regional jet that flipped upside down while landing at Toronto Pearson Airport, injuring 21 people.

The CRJ900 aircraft, operated by Endeavor Air, suffered structural damage upon impact, with parts detaching and a fire igniting, said Ken Webster of the Transportation Safety Board of Canada (TSB). A team of over 20 investigators is working with U.S. and Canadian regulators to determine the cause.

Weather conditions included gusting crosswinds and blowing snow, with flight data showing a flat landing instead of the usual flare maneuver to slow descent. Experts, including U.S. aviation safety analyst John Cox, say it is too early to determine the exact cause.

The 16-year-old CRJ900, built by Bombardier and powered by GE Aerospace engines, carried 80 people. Footage from the crash site shows at least one wing detached from the fuselage.
