A parliamentary commission investigating last month’s plane crash in Sao Paolo made public preliminary results of the examination, pointing the finger at an engine throttle and spoilers that failed to respond to the pilots commands.

On July 17, a TAM Linhas Aereas Airbus A320 skidded of Sao Paulo's Congonhas airport runway while trying to land, crossed a crowded highway and crashed into a depot of the airport and another building. All passengers and crew members were killed after the aircraft bursted into flames,  making the accident Brazil’s worst air accident in history.

Based on data present on the plane’s flight recorder data, investigators said human error can be ruled out due to the faulty braking equipment.

“It is irresponsible to say it was pilot error. ... All the standard landing procedures were carried out. It is premature to say the pilots were responsible,” spokesman of the investigating panel Marco Maia said.

It is supposed that the computer failed to respond when pilots began the landing procedure, TAM acknowledging that one of the reverse thrusters wasn’t working properly.

Another factor initially blamed for the tragic accident was the short runway recently re-opened at Congonhas airport that didn’t have grooves, essential features that permit the water from rainfall to drain quickly.

“The runway had a smaller influence. It may have contributed, but was not the dominant factor,” Maia said referring to the supposed cause.

The pilots tried to land on a “wet and slippery” runway, as the local traffic controllers informed them. But without functional spoilers and throttle, the pilots found it very hard to follow standard procedure that eventually proved to be useless.

The final words said inside the cockpit were also made public by the commission, people hearing the copilot desperately shouting “Look at that! Decelerate, decelerate, decelerate!”

His colleague’s response being “I can't, I can't!” right before a terrifying “Oh God, oh God!” ended the dramatic conversation.

Scandals and turmoil have been ravaging Brazil’s aviation after a Boeing 737 crashed into the Amazon region last September, killing 154 persons.
