At least six people died and a youngster was injured in two air accidents in Brazil over the past 24 hours, authorities of the western state of Mato Grosso and the southern state of Santa Catarina reported Saturday.

The first crash, in which four people were killed, occurred Friday afternoon in the mountainous region of Chapada dos Guimaraes, at 65 kilometers (40 miles) from Cuiaba, the capital of Mato Grosso, a state bordering on Bolivia, municipal firefighters said.

Aboard the twin-engine plane, the pilot and copilot were flying two engineers of the Mato Grosso Transport Secretariat who had supervised paving works in Confresa, at 1,160 kilometers (720 miles) from Cuiaba, and lost control of the aircraft while approaching the regional capital.

In a similar accident on the coast of Santa Caterina state bordering on Argentina, a single-engine plane went down in the sea on Saturday near the beach of Taquarinhas in the city of Camboriu.

According to state police, flying in the aircraft were the pilot, an adult and an 11-year-old boy, who was the only survivor and who was hospitalized but without serious injuries. EFE
