'Mechanical flaw didn't cause Brazil plane crash'

Mechanical failure did not contribute to last month's crash of an Airbus A320 in Sao Paulo, a senior executive with the aircraft manufacturer said Thursday. Testifying before Brazil's congress, the Airbus executive said the flight data recorders of the ill-fated plane did not show any flaws that would have prevented the aircraft from operating normally. On July 17, TAM flight 3054 sped down the runway at Congonhas airport, Brazil's busiest, jumped a major highway and slammed into an air cargo building, killing all 187 people aboard and 12 people on the ground in Brazil's deadliest air disaster.
