A lever used to control engine speed was in the wrong position when a Brazilian plane crashed last month and likely was a major cause of the country’s worst air accident, according to flight recorder transcripts published by a newspaper on Wednesday. An Airbus A320 operated by Brazilian carrier TAM Linhas Aereas barrelled off the runway upon landing at Congonhas airport in Sao Paulo on July 17, crashed into a cargo terminal and burst into flames. All 187 people aboard and at least 12 more on the ground were killed. Data from the flight recorder suggests that the thrust lever for one of the turbines was in “accelerate” position, Folha de Sao Paulo newspaper reported.
