A private plane crashed in Brazil's northeastern state of Bahia, killing 14 people, including four children, said Brazilian air force sources.

The twin-engine plane was coming from Sao Paulo and crashed late on Friday about 730 km from Salvador in Bahia state, near a luxury resort.

An air force spokesman said there was no report of survivors. The plane was owned by Roger Wright, owner of financial consulting firm Arsenal Investimentos, who was on board with his wife and two children.

The cause of the crash is still unknown. Air force sources said the plane's black box was found and being analyzed. A spokeswoman at Brazil's National Civil Aviation Agency said the plane, a King Air B350, had been inspected and that its documents were in order.

Brazil had two major plane crashes in 2006 and 2007, raising concerns about the safety of air travel in Latin America's largest country.

In July 2007, all 187 people on board and 12 people on the ground died when a TAM airline Airbus A 320 overshot a runway at Sao Paulo's Congonhas airport.

In September 2006, a Gol airline passenger jet crashed in the Amazon jungle after colliding with a small private plane, all 154 people on board died.
