RIO DE JANEIRO, July 30 (Xinhua) -- Human error is to blame for the worst accident in Brazil's aviation history on July 17, the weekly magazine Veja claimed Monday.
Veja based its report on sources that allegedly have had access to the contents of the black box flight data recorder and the cockpit voice recorder. The contents of recorders currently remain under wraps by the Brazilian Air Force.
The sources revealed that the pilots incorrectly adjusted the levers that control the thrust reversal system, causing the engines to work in different directions. This meant that while theleft engine helped the plane slow down, the right one forced it to accelerate.
That could explain why the airplane swerved to the left as it approached the runway's end at Congonhas International Airport, in Sao Paulo.
The analysis of the fight recorders, carried out by the U.S. National Transportation Safety organization, showed that the plane did not skid on the runway flooded with rainwater, and the undercarriage brakes worked when it landed, said the report.
Brazil's Air Force would not confirm the report by Veja, which contradicts previous explanations of the causes of the disaster.
Following the accident, local press and some analysts blamed the recently resurfaced runway for the tragedy. The grooving service, which prevents planes from skidding on rainy days, had still not been completed by the time of the crash.
