Mysterious stuff. The wording on this question kind of made me laugh: "Why did the anti-collision system not work at the moment of impact?" If they collided, then it wasn't working before the impact either!

Yep! I am beginning to think that someone or a number of people ****ed up big time somewhere and this was the result.
 
I found a bit more on the story apparentlly the the Legacy was not being tracked on radar and was following his flight plan he had been cleared to fl370 and upon making a turn had descended to fl360 as per flight plan . This info was released after reviewing the radar tapes . I'm going to guess that the radar tapes are possibly from the brasilian air defence radar

INTERESTING! I haven't heard much on this lately.
 
here is another tidbit:

Did Not Notice Legacy's Transponder Was Inactive
An unidentified Brazilian air traffic controller, working at the center responsible for directing traffic in the area where a Gol airlines 737 and a private business jet collided last month, told Newsday controllers had more than an hour to notice the smaller aircraft's transponder wasn't working at the time of the fatal accident that claimed 154 people.

The controller -- who stressed he was not involved in directing the planes involved in the accident -- also says controllers had plenty of time to notice the planes were on a collision course, even without the avoidance equipment.

"It is always our responsibility to maintain the separations," said the controller. "In this case, when you don't know the altitude, it is very dangerous." "I would have preferred to move them laterally, but it is always our responsibility to keep them separated."

As Aero-News reported, authorities have said controllers at two centers -- Brasilia, where the controller interviewed by Newsday works, and Manaus -- had directed the aircraft to the same altitude of 37,000 feet. All onboard the 737 were lost; amazingly, those onboard the bizjet, an Embraer Legacy 600 on a delivery flight to the US, survived after the plane's pilots executed an emergency landing.



Those pilots -- Americans Jan Paladino and Joseph Lepore -- had their passports immediately after the accident, and are still being held in Brazil. The two men say they were operating under control of the Brasilia center.

The Legacy's transponder apparently failed some time before the crash. The failure was not noticed by the pilots, or by controllers.



"Airspace Control [personnel] should have the main responsibility for monitoring and controlling aircraft," said Renato Claudio Costa Pereira, a retired Air Force major general who led the International Civil Aviation Organization for six years until 2003. "Transponders and TCAS [electronic collision avoidance equipment] are to be used as a last resort in any traffic conflict emergency."

A spokesman for the Brazilian Air Force, which oversees all air traffic control operations in the country, declined to comment
 
BINGO!! A Smoking Gun!

There is no reason for these seemingly professional corporate pilots to risk their career by "purposely" turning off their transponder while in A airspace. I'm sorry but I have to say they were the easy scapegoats becuase they came out alive and because they were Americans.....
 
While just rumour, I have it on fairly good source that the Legacy pilots may have been "goofing around". Nothing to back that up, but those are the rumblings at the office.

If true, they are in deep kimchee.

Off the top I find that unlikely...

There was no report of anything unusual happening except their transponder not functioning. - I think radar might of been able to track them "squawkless" and if so would of shown changes in altitude in excess of IFR requirements...
 
Don't know. But with lots of critical equipment "off" seems strange. Folks from our office are involved in investigation. But what I noted above is PURELY rumour.

Their VHF radio was also off. Not sure what that means as there is not an OFF button on the audio control panel for a particular radio that I'm aware of for TSO-C37/C38 equipment installed in Part 25 airplanes. It may be that they were (1) either not monitoring VHF1, VHF2 and/or VHF3 or (2) they were not monitoring proper ATC freq.

Too many plain silly deviations from normal operation to be comprehensible.
 
A search radar should be able to track a primary target meaning the actual reflection of the radar off the aircraft skin rather then the secondary which is the transponder but it depends on so much such as the gains on the radar mti degrades the signal ,atmospherics
But it still boils down to whether the ATC instruction caused the conflict or disobeying the instruction. It is not uncommon to control IMC procedurally or without radar
 
I guess we'll have to wait for the tapes. They still claim they attempted to contact the Legacy airplane four times. We'll see.
 
Seattle Times - World Report Friday November 3, 2006

"The flight recorder transcript from the executive jet involved in Brazil's worst air disaster shows its American pilots were told by air traffic control to fly at the same altitude as a Boeing 737 before the planes collided over the Amazon rainforest, a newspaper reported Thursday.

Pilot Joseph Lepore was told by the tower in Sao Jose' dos Campos to maintain an altitude of 37,000 feet as he flew the jet beyond Brasilia' on a northwest path to Manaus, the Folha de S. Paulo quoted the transcript as saying. That altitude contradicted the pilots' filed flight plan as well as established norms, which reserve odd-numbered altitudes for southbound flights.

The Defense Ministry was not able to confirm the report."

Given that the flight recorder sources from the Audio Control Panel and not from the radios directly, this would seem to indicate that the claims of the controllers attempting to contact the Legacy aircraft are false. The only way to conclusively tell if this were so, would be to obtain the ground recordings too. However, as FBJ noted, it certainly does not look like that scenario is going to play out. It seems highly unlikely that the Legacy pilots would be monitoring ATC, accept and act upon a flight level change, and then cease monitoring the same channel.

This does raise some interesting questions that are likely to be raised in civil courts. ATC controls the airspace and has a primary job of maintaining separation. The airspace has well known and published procedural means of maintaining differing flight levels for airspace users (even/odd flight levels depending upon direction traveled). And pilots are ultimately responsible for the continued safe flight and landing of their aircraft. These roles and responsibilities have often times been challenged in the past.
 
Sorry N-6-0-0-X-L has been translated by the forum to be N600XL.

This information from G1 > Colunistas > Entrelinhas

Control of Air traffic
At 15:51 o'clock (schedule of Brasília), there was the last bilateral contact of N600XL with the Brasília Center. (Freq. 125.05 MHz)
At 15:55 o'clock, N600XL flew over the vertical of VOR of Brasília, maintaining the level of flight 370 and entering in the airway UZ6, without to request or to receive any instruction of the Brasília Center.
At 16:02 o'clock, there was the loss of information of the secondary radar with N600XL, that introduces to the controller, accurately, the altitude information.
Among 15:51 (schedule of Brasília) and 16:26 (schedule of Brasília), there was not any contact attempt, nor on the part of N600XL, nor on the part of the Brasília Center.
At 16:30 o'clock (schedule of Brasília) there was momentary loss (2 minutes) of the contact primary radar with N600XL, that transmits to the controller the geographical position of the aircraft.

Starting from the 16:26 (schedule of Brasília), the BR Center accomplished seven calls:
16:26
16:27
16h30min40
16h30min56
16:32
16:34
16h53min39

At 16:38 o'clock (schedule of Brasília) the Brasília Center lost the contact primary radar definitively with N600XL, until it transfer for the Amazonian Center.
At 16h53min39 (schedule of Brasília), the Brasília Center made the last call, blindly, informing N600XL to call the Amazonian Center, supplying two frequencies: 123.32Mhz and alternative 126.45Mhz.

Flight of N600XL
N600XL, at 16h48min16 o'clock (schedule of Brasília), it began a series of 12 calls to the Brasília Center:
16h48min16
16h48min40
16h49min33
16h50min08
16h50min28
16h50min48
16h51min08
16h51min24
16h51min41
16h52min10
16h52min42
16h52min59

At 16h53min39 o'clock (schedule of Brasília), N600XL got to hear Brasília's Center last call, blindly, guiding to call the Amazonian Center, without getting to copy the frequencies.
At 16h53min57 o'clock (schedule of Brasília), N600XL answered to the Brasília Center asking so that they were repeated the decimals of the first informed frequency, because he didn't get to copy them. The Center didn't receive this message.
After this moment, N600XL accomplished more seven calls to the Brasília Center:
16h54min16
16h54min40
16h55min00
16h55min43
16h56min41
16h56min53
16h55min16
At 16h56min54 o'clock (schedule of Brasília) it happens the collision.

General Considerations
Not happened any loss of contact radar for the Amazonian Center with the flight 1907, until it transfer for the Brasília Center.
There are no request registrations of N600XL to the control organs, to accomplish level change, after having reached the level of flight 370.
There are no registrations of any instruction of the control to N600XL, in the sense that level changes were accomplished, after the last contact bilateral good happened between that aircraft and the Brasília Center.
The aircrafts were, in the airway UZ6, in opposite directions, in the level of flight 370.

The system TCAS (System embarked to avoid Collision in Flight), existent in both aircrafts, it didn't emit any warning of alert of traffic or of instruction for evasive action, for the respective crews, in the sense of avoiding the collision.
There was not manifestation, for none of the crews, regarding a possible previous visual perception of the approach of the aircrafts.
It didn't happen any action attempt or it maneuvers evasive, in agreement with the existent data in the flight tape recorders.
At 16h56min54 o'clock (schedule of Brasília) there was a COLLISION, possibly, between the left wing of N600XL and the left wing of the flight 1907.
The flight 1907, after the collision, was uncontrollable to the pilots, beginning immediate dive until the soil.
The tape recorders of flight data (CVR and DFDR) of the flight 1907 had it operation interrupted to 7887ft of altitude.
After this moment, N600XL accomplished 09 (nine) calls to the Brasília Center:
16h57min47
16h58min09
16h58min47
17h02min40
17h03min11
17h03min41
17h03min50
17h04min03

At 16h59min50 o'clock (schedule of Brasília), approximately three minutes after the collision, the Amazonian Center started to receive information of the secondary radar, with precise altitude needs and identification code allocated N600XL.
At 17h00min30 o'clock (schedule of Brasília), the Amazonian Center accomplished a call to N600XL, without obtaining answer.
At 17h01min22 o'clock (schedule of Brasília) N600XL tried to establish communication with the Amazonian Center, through the Polar 71, requesting coordination to accomplish a landing in Test Field Brig. Veloso.
At 17h02min10 o'clock (schedule of Brasília), the Amazonian Center started to receive information of the secondary radar, originating from of the change of the code transponder of N600XL, for 7700 (EMERGENCY).
At 17h03min11 o'clock (schedule of Brasília) N600XL, after the collision, declared EMERGENCY, without getting communication with the Brasília Center, and it began procedures to accomplish an emergency landing.
The Amazonian Center accomplished more four calls to N600XL, without obtaining answer:
17h10min41
17h10min50
17h11min00
17h12min44

At 17h13min16 o'clock (schedule of Brasília) the Polar 71 established communication with the Amazonian Center declaring the situation of EMERGENCY of N600XL.

Accomplished actions
Recovery of the data of the registrars of flight of N600XL and of the flight 1907.
Interviews and medical examinations with the crew members of Legacy. (02/10)
All requested the data registered by the Control of Air traffic, relative the occurrence. (02/10)
Tests preliminaries of equipments in the Legacy (07/10/06).
Verification of the wreckage of the 737-800, in the place of the accident.
Reading and processing of the data of the flight registrars, of both aircrafts, except the voice registrar (CVR), of the flight 1907, in TSB Ottawa, Canada.
Preliminary analysis of the recordings and transcriptions of the communications between the aircrafts and control organs.
Verification of the equipments of the wreckage of the flight 1907.
Send of the voice registrar (CVR) of the flight 1907 for the Laboratory of TSB, Ottawa, Canada.
Verification of the data, relative the visualization radar, registered by the organs of control of the air space, with works accomplished in the dependences of CINDACTA 1, in Brasília, and in the dependences of CINDACTA 4, in Manaus.

Next actions
Analyses of the equipments of radio and navigation, communication, transponder and TCAS, of the aircrafts, they be accomplished at laboratory.
Interviews with the controllers of Air traffic.
Relative works to the air traffic, they be accomplished in the USA, to invitation of FAA, for analysis, among other subjects, of the norms and prerequisites for American pilots fly in the exterior.
Works and interviews with the operators.

Summarize of the current situation
Collects of data still given no completed and initiate analyses for focal points, among other, related the:
Operation of Transponder and equipments of radio and navigation of the aircraft N600XL;
Knowledge and preparation foreseen the pilots of N600XL, for the accomplishment of the flight in Brazil;
Relative aspects to norms and procedures of the Control of Air traffic, now in use in Brazil and in the world;
Systems and equipments of communications and system of surveillance of the Control of Air traffic.
In the moment, any conclusion will be premature
Recommendations can be emitted, before the final conclusion of the investigation process.
Data factuals and recommendations of flight safety, will be informed to the public.
 
I thought all the transcripts would have been in the language of ATC english with maybe the exception of the crew chat of the GOL that transcript sounds convoluted .

Lepore, Paladino Due In Court In August
Two US pilots and four air traffic controllers were indicted by a Brazilian judge Friday, on manslaughter-related charges stemming from a September 2006 midair collision that killed 154 people onboard a Gol Airlines 737.

The Associated Press reports Judge Murilo Mendes accepted charges made by a federal prosecutor last week. The decision has not been published yet in the official Brazilian newspaper Diario Oficial, according to court spokesman Fabio Paz. When that happens, those indicted will have five days to appeal the charges.

As ANN reported, an Embraer Legacy 600 piloted by Joseph Lepore and Jan Paladino clipped the 737. The bizjet was able to made an emergency landing with its wingtip missing; the 737 crashed into the Amazon jungle following the September 29 accident.

Both pilots have denied any wrongdoing in the accident. The two aircraft collided at 37,000 feet, an altitude normally reserved by ICAO guidelines for eastbound aircraft. Lepore and Paladino were flying on a northwesterly heading, and wouldn't normally have been at that altitude... but Paladino said they were flying at an altitude assigned by ATC, adding, "Air traffic controllers have responsibility to manage that traffic."

"We were compliant with all regulations," Paladino said in a December interview. "We were doing exactly what we were supposed to be doing, and we just experienced, automatically, just a jolt out of nowhere."

Lepore and Paladino were detained in a Rio de Janeiro hotel for over two months following the accident. They were allowed to leave Brazil in December, but not before being charged by police for "endangering air safety." Both men are expected to appear before a Brazilian court for interrogation on August 27.

Air traffic controllers Jomarcelo Fernandes Dos Santos, Lucivando Tiburcio De Alencar, Leandro Jose Santos De Barros and Felipe Santos Dos Reis will appear before the court the next day.



Both pilots and three of the controllers face charges similar to involuntary manslaughter for their alleged roles in the accident, and face 1-3 years in prison if convicted. A fourth controller is charged with the more serious crime of knowingly exposing an aircraft to danger.

Joel Weiss, the attorney for the pilots, stressed the judge's decision Friday "has nothing to do with guilt or innocence," but rather whether or not the prosecutor's allegations should be presented before the court.



"The pilots' conduct was completely competent throughout the flight and cannot be fairly characterized as criminal," Weiss told the AP. "The allegations against the pilots are inaccurate, and the pilots are innocent."

An investigation into the accident is still ongoing
