After the crash, rescue workers and fishermen helped the survivors to shore, Reverol said on state television.
A 62-year-old woman died in the accident, the country's civil aviation agency said in a statement. The five survivors, including a boy and the pilot, were brought ashore in boats and treated at a hospital, said Gen. Francisco Paz Fleitas, president of the National Civil Aviation Institute.
The plane had been flying from Puerto Ordaz to Venezuela's Margarita Island when it went down.
