An airline worker in Texas was killed by being sucked into the engine of a taxiing Delt Airbus A319 at San Antonio airport.
The worker's employers say an initial investigation shows the incident was unrelated to safety procedures, but it is not yet clear how it happened. An investigation is also being carried out by a government agency.
The National Transportation Safety Board is "in the information gathering process at this point," in connection with Delta Airlines. Delta stated that it was 'heartbroken by the loss of an "aviation family member's life. Our hearts and full support are with their family, friends and loved ones during this difficult time."
BBC reports that officials have not yet named the employee of Unifi Aviation, which Delta Air Lines contracts for ground crew operations, and that the company claims that "From our initial investigation, this incident was unrelated to Unifi's operational processes, safety procedures and policies."
On Wednesday, regional airline Piedmont was fined $15,625 by the Occupational Safety and Health Administration (OSHA) for the death of a ground crew worker six-months earlier in a similar incident in Alabama.
"Proper training and enforcement of safety procedures could have prevented this tragedy," OSHA said.
