TAM mechanics made a deposition at a CPI of the House, and said that they did work on the maintenance of the A320 that crashed fours days before. That they did have the part that was needed for the right reverser and that it would take three hours to replace it. But it had to be done at night and it would be noisy because the engine would have to work. So he consulted his supervisor who advised him to just lock the right reverser because according to Airbus the plane could fly ten days without it working.
Also the technical guy from National Agency for Civil Aviation (ANAC) said that it was decided internally that planes to land in Congonhas had to have both reversers and that this direction was published in their site. He believed that this was to be followed but for some reason another director of ANAC said that this was not so and TAM said that they followed the Airbus directives, not ANAC. What a mess...
There is nothing peculiar about the acceleration of the other engine. It is only the autothrust trying to maintain the selected speed. As the other engine was put to IDLE, the remaining engine fights the sudden loss of energy, as the autothrottle still remained connected and tried to achieve the selected approach speed.
Before the three wheels touched the ground?
Thanks.
