The last issue of Aeromagazine is out. www.aeromagazine.com.br

It mentions the TAM accident two times.

1. One saying that AB sent a note (AIT 4) with considerations about Flight 3054 from TAM saying that there were nothing abnormal about the plane. But now some information in the AIT 4 are being contested by pilots and security especialists. AB states that "manual actions for plain breaking started 11 seconds after touchdown". However analysis of FDR show that the pilots applied maximum breaking only 5 seconds after touching down. In the final text of the AIT 4 they say that " the data of the recordings DFDR and CVR donīt show evidence of malfunction in the airplane". But sources cinnected to the investigation said that the information only refers to the state of the black boxes of the airplane and not to all systems.

2.The TLs. There is a enigma of the TLs of autothrust. According to FDR the right motor had the reverser blocked and presented a peak of potency seconds before touch down and after that deccelerates a little but remained accelerating while the reverser of the left motor was applied. However the TL of the right motor was not in the Climb position and instead was half the way betwenn Idle and Climb (22.5 degrees). The suspition problems with the software were at work became more important after the pilot Marco Aurelio Incerti from TAM who piloted the plane on the day of the accident said that he did not follow the recommendation of AB for landing with one reverse locked out. He said that when he landed he went into reverse with motor 1 and he left the TL on motor 2 on Idle. CENIPA os also investigating a voice in the cockpit that was not in the transcript saying that the "TL doesnīt move, it is jammed".
