Disappearing time: September 29th, 2006, local time 16: 48. Introduction, courses, aircraft types, airline information, survey. Handling, similar to the accident, briefly introduced that all six crew members on board, 148 passengers and 154 people were killed. This is the most fatal air crash in Brazilian aviation history before the air crash of Tianma Airlines Flight 3054 on July 17, 2007. There were no casualties in the Gracie plane that collided with it. . After September 29th, 2006 14: 36 local time, 1907 took off from Manaus, the capital of Amazon, stopping in Brasilia and ending in Rio de Janeiro. Disappeared from the radar on September 29th, 2006 16: 48 local time. The signal of flight 1907 disappeared from the radar screen of the civil aviation air traffic control center. The last signal of the plane was located in the Amazon rainforest mountain area of Kashimbu, Pará. The passenger plane was originally scheduled to arrive in Brasilia on September 29, 2006 18: 02, but it did not arrive in Brasilia for a long time. After that, Gore Airlines issued a statement confirming that the passenger plane was missing. Discovery of wreckage: At about 9: 00 am local time on September 30, 2006, the Brazilian Air Force found the wreckage of the crashed passenger plane near an Indian tribe in Mato Grosso. This is the second air crash of Boeing 737 in the same airspace. 1989, a 737-200 passenger plane crashed locally with 54 people on board, and 4 1 survived. 1907 is a brand-new Boeing 737-800. It was put into use on September 12, 2006, with only 200 hours flight time until the crash. Boeing 737-800 is a new passenger plane of Boeing Company. Boeing fully considered the requirements of advancement and comfort, and adopted new wings and engines while retaining the traditional front end and fuselage cross section. Legacy N600XL is a super medium-sized commercial airliner developed by Embraer. It is a modified regional aircraft with a maximum passenger capacity of 16 and a value of $25 million. The Legacy 600 that collided this time belongs to the American business jet company Excellence Aviation, and Joseph Leport and Gianpaletino are responsible for the maiden voyage of this jet. Airline Information Brazil Gore Airlines was founded in 200 1 by a family business in Brazil, and was led by Constantino Olivia, who was only 32 years old at that time. Gore Airlines is one of the most successful low-cost airlines in the world. In 2006, CEO Constantino Olivia was awarded the Best Low-cost Airline Leader Award by Aviation Business, an internationally renowned aviation magazine. Gore Airlines is the second largest airline in Brazil, and its domestic market share exceeded 1/4 in the past five years. Like other low-cost airlines, there is no special aircraft maintenance logistics department, and its aircraft is contracted to a third-party maintenance company. Investigation Colonel Sanfino Ferreira is responsible for investigating the accident of Gore Airlines 1907 flight. At the same time that the business jet of Excellence Airlines landed successfully, the tower in Brasilia said that Gore Airlines 1907 flight suddenly disappeared. The missing place happened to be the airspace where the business jet crashed. Rescuers found that until the next morning, the wreckage of flight 1907 was still scattered in the Amazon rainforest area, with a length of more than two kilometers. Inferred from the scattered situation, the plane had disintegrated before falling to the ground. According to the flight data recorder of the black box, the plane was flying normally, suddenly tilted to the left, rolled in the air 1 1 times, and finally disintegrated because it could not bear the pressure. Investigators found that there was a gap on the left wing of the wreckage of the passenger plane, which was obviously cut off. About half of the left wing was cut off by another plane at high altitude, causing the plane to stall and disintegrate. When the investigators retrieved the memory needed by the cockpit recorder, they found that the crew of flight 1907 did not send out a distress signal at the time of the incident, which showed that the incident was sudden and neither plane looked at the other. The crew did not know that they had collided with another passenger plane, and finally they were unable to save the damaged passenger plane that was out of control. Investigators also found that for some reason, two planes were destined to collide because of the same route. After investigation, it was necessary for Gracie N600XL to lower its flying altitude to 36.000 feet in Brasilia, but the investigation found that the plane did not lower to the designated altitude as required, resulting in a collision accident. The flight path of the cause of the accident was set over Brasilia, and the flight altitude of N600XL should be reduced from 37,000 feet to 36,000 feet. However, the controller in charge of ordering the business jet at that time did not order the business jet to descend to the specified height. On the one hand, the altitude instructions in other parts of the world have been manually changed, and the flight altitude instructions displayed in this pc are automatically updated by the computer. The controller is not familiar with computer operation, and the air traffic controller misunderstood the flying height instruction. On the other hand, Gracie's pilot was not familiar with the operation mode of Legacy 600 and turned off the transponder by mistake. The instruments in the control tower are automatically converted into active radar to receive the position of the aircraft. Because the active radar is unreliable, their subsequent records found that the business jet was flying in a dangerous way, but in fact it was flying in a normal way. Handling means that air traffic controllers have insufficient English level, long working hours and are not familiar with computer operation procedures. The air traffic control center has undergone a thorough reform. The captain of the Glazer received a serious warning. Air traffic controllers are accused of murder to varying degrees.
