Fourteen people on a small jet died when the plane crashed in Brazil's northern Amazonas state on Saturday, the state's governor said.
The accident took place in the Barcelos province, some 400 km (248 miles) from the state capital, Manaus.
"I deeply regret the death of the 12 passengers and two crew members who were victims of the plane crash in Barcelos on Saturday," said Wilson Lima, Governor of Amazonas state on X, formerly known as Twitter.
The Brazilian Air Force (FAB) said in a statement that investigators from the Accident Investigation and Prevention Center (CENIPA) had been called in to begin an investigation into the reasons for the crash of the small aircraft, an Embraer Bandeirante with the registration PT-SOG.
In an interview with O Globo newspaper, Governor Lima said that the bodies had already been removed from the aircraft and that the victims were Brazilian tourists.
Lima also added that the region faces heavy rainfall and the most likely cause of the accident was an error in the route taken at the time of landing.
