(CNN) - A worker at the Montgomery Regional Airport in Alabama died Saturday in an incident on the ramp, the Federal Aviation Administration said Saturday.

The Montgomery Regional Airport said in a statement an American Airlines/Piedmont Airlines ground crew employee was “involved in a fatality” around 3 p.m.

“We are saddened to hear about the tragic loss of a team member of the AA/Piedmont Airlines,” said Wade A. Davis, the airport’s executive director. “Our thoughts and prayers are with the family during this difficult time.”

All flights outbound and inbound at the airport have been grounded until further notice, the statement said. An FAA website listed the airport as closed Saturday evening.

The victim was not named, and the circumstances of the death were not immediately released. The FAA and the National Transportation Safety Board will both investigate.

The flight, operated by regional carrier Envoy Air, was scheduled to depart Montgomery for Dallas-Fort Worth Saturday afternoon, according to the flight tracking site FlightAware.com.
