EXAM DOESN'T POINT FLAW IN TRANSPONDER OF LEGACY
...reinforces the lifted up suspicions soon after the tragedy that the apparel would have been turned off by the American pilots, although unaware, for inobservance of procedures or for 'to test' the jet, making maneuvers.
The military say that the breakdown in a transponder is acceptable. For technicians of the Aeronautics, the disconnection of the transponder is still the cause number one of the collision.
I think this is a good clip of what the 'US pilot support contingent' are concerned about.
To raise up again the demonstrated false (via FDR and CVR data) allegation that the Legacy was maneuvering or 'testing performance' is unbelievable.
The fact that this and a series of other demonstrated false acusations were made by Brazilian officials speaks to poor investigative practice. It also probably kicked off the whole criminalisation thing.
If the NTSB or AAIB said "Pilot A was performing unauthorised maneuvers in contravention to his clearance prior to (collision, crash, some other bad thing)", I would expect a crimianal investigation to be launched and charges to be brought. It is a disappointment (and hopefully only releated to the specific individuals involved rather than the Brazilian Government in general) that just such serious allegations were made without any substance - in a situation where a few weeks of investigation would have demonstrated the lack of fact surounding these allegations.
It is also very worrying if the "technicians of the Aeronautics" believe that the failure of the transponder is the primary cause of the accident - This would indicate that Brazilian ATC is a fail dangerous system! And one that doesn't appear to be reliable in detecting this critical failure!
