AIR CRASH INVESTIGATIONS FAILING BRAKES The Crash of TAM Linhas Aereas Flight JJ3054

Book excerpt: On 17 July 2007, at 17:19 local time, an Airbus A-320, operated as flight JJ3054 by TAM Linhas Aéreas, was on its way from Porto Alegre, Brazil, for a domestic flight to Congonhas Airport in São Paulo city, São Paulo State, Brazil. During the landing, at 18:54 local time, the aircraft veered to the left, overran the left edge of the runway, collided with a building, and with a fuel service station. All persons on board - six crewmembers, and 181 passengers - perished. The crash also caused 12 fatalities on the ground. The runway had recently been resurfaced, but it did not yet have water-channeling grooves cut into it to reduce the danger of hydroplaning, making landing during rain a dangerous endeavour. Flight Data Recorder information showed that immediately prior to touchdown, both thrust levers were in CL (or "climb") position, with engine power being governed by the flight computer's autothrottle system.
