The Sikorsky UH-60 crashed into a marsh near Leesburg International Airport, about 35 miles (56 km) northwest of Orlando, around 4 p.m. EDT (2000 GMT) on Tuesday, the Federal Aviation Administration said in a statement on Wednesday.
The Leesburg Fire Department, which responded to the crash, confirmed one death, but said it had not located any survivors.
“The crash appears to be a total loss,” the department said on Facebook (NASDAQ:FB) on Tuesday evening, adding that it had gotten the fire under control.
The posting included a picture showing a plume of black smoke coming from vegetation beyond a taxiway of the airport.
The National Transportation Safety Administration said in a statement that it was sending investigators to the scene.
