No fatalities, 23 injured passengers on Delta flight

Passengers struggled with seat belts due to inversion

March 20 (Reuters) - A safety warning system went off in

a Delta Air Lines ( DAL ) regional jet before it landed and

flipped belly-up at Canada's largest airport in February,

indicating a fast rate of descent, the country's Transportation

Safety Board (TSB) said on Thursday in a preliminary report on

the accident.

Despite nearly two dozen injured passengers, none of the 80

people died on board flight DL4819, a CRJ900 jet operated by

Delta's Endeavor Air subsidiary from Minneapolis-St. Paul

International Airport.

Video capturing the plane turning over after landing and missing

its right wing at Canada's largest airport had circulated widely

on social media. Several recent high-profile air crashes have

been cited by some U.S. airline CEOs as contributing factors to

dampening domestic travel demand.

"Some passengers had difficulty releasing the buckles on

their safety belts due to being inverted," the report said.

"Some of the injuries sustained by the passengers occurred when

they unbuckled their safety belts and fell to the ceiling. The

TSB is not aware of any safety belt or seat failures occurring

during the accident."

The TSB's preliminary report into the February 17 incident

at Toronto's Pearson Airport also provided details on

the experience of crew members

. The jet's captain had worked for Endeavor Air since 2007

and had 3,570 hours of total flight time while the first officer

had had 1,422 hours of total flight time.
