American Airlines Mechanic Killed in Accident at Dallas/Fort Worth International Airport (KDFW), Texas

A mechanic who had worked for American Airlines for 30 years died Monday after falling from a jet bridge at Dallas/Fort Worth International Airport.

NBC 5 has learned the mechanic was closing and locking the door on a Boeing 767 at about 10:30 a.m. when he somehow slipped and fell about 14 feet from the jet bridge to the ground below.

The plane, sources said, had just been moved from a maintenance hangar to Gate D30.

Emergency responders with the airport treated and transported the man to a hospital, airport officials said.

Transport Workers Union Local 591 identified the man as aircraft maintenance technician Dave Ostang  and asked for thoughts and prayers for his family.

American Airlines has confirmed the employee's death, but did not confirm his name or specifics about the incident in a statement released to the media Monday.

"We extend our deepest sympathies to our co-worker's family and friends, and our hearts go out to our entire team of DFW airport and maintenance colleagues. Our focus is on taking care of his family and friends during this difficult time,” the airline said in a statement.

A jet bridge is the elevated gangway used by passengers to walk from the terminal to an airplane.
