An investigation of the causes of the Boeing-737 disaster, flying from Moscow to Perm. Assumptions and guesses. But people are ready to believe rumors and random witnesses more than what representatives of the authorities say. The reason is obvious: when in August 2004 two aircraft of Siberia Airlines exploded, the authorities categorically denied that these were terrorist attacks. But they were. What happened in Perm September 14 - The New Times compared the facts and assumptions
On the early morning of September 14, the inscription hung for a long time on the online score of the Perm airport of Savino: “The flight is delayed”. The Boeing-737-500 aircraft Aeroflotnord Airlines flew out of Sheremetyevo on Sunday at 01.12 Moscow time. Communication with pilots disappeared at 03.10 Moscow time (05.10 local time). Half an hour later, the liner fell to the ground near the residential quarters. All 88 people were killed on board.
Specialists of the Interstate Aviation Committee (IAC) are deciphering on -board - speech and parametric - self -writers, but the results of their work will not be fully earlier than mid -October. There are more questions in this story than answers. In the air, pilots say, one axiom should be remembered: plane crash do not arise for one single reason, most often this is an unlucky coincidence of several negative factors at once.
Questions against answers
The question remains open: when did the fire occurred - in the air or when the plane hit the ground? Was there a fire on board the aircraft before it falls? In the media there was information that the right engine caught fire in the air of the plane. But could the crew not notice this? A red bulb would have blinked, a siren would overtake. “And the plane behaves differently, it immediately crawls towards the refusal of the engine, it requires the crew’s intervention. But if it was, then why didn’t the crew report to the ground? The pilot said that everything was fine, ”says Oleg Smirnov, president of the Civil Aviation Partner Foundation.
In the very first hours of the tragedy, many eyewitnesses appeared who said that they saw a plane burning in the air. Someone claimed that "the clouds were shining." “Yes, of course, they will glow, - explains Oleg Smirnov, - they were low, at an altitude of 240 meters. As a result of the explosion from the collision with the ground, this torch arose (there were several more tons of fuel in the tank), it could highlight the clouds from below. People could see the glare from the flame. "
In addition, when there is a fire in the engine, due to high temperature, the metal begins to melt, ”experts explain. The turbine rotates at great speed, and her shoulder blades break away from their nests and fly, breaking through everything in their path. Theoretically, they can damage the steering, and burners, and some other system. But the crew did not report on the ground about this.
On September 18, the MAC Commission stated that it did not reveal the fire of the engines and the destruction of the aircraft before its collision with the ground. However, some experts doubt it. “I was immediately alerted by the place of fall,” explains Mikhail Markov, deputy leader of the Aeroflot Plus company , who had previously investigated a number of plane crashes. - There was a huge scatter of small elements. The engine can fly away two kilometers from the explosion on the ground, but the trifle does not fly away. Try to throw it out of paper. Why then such a huge scatter? And the second question: where is the epicenter? Where is the pit, where did he crash? And she is not. The guys who were there say that there is no obvious epicenter. ” In other words, it cannot be excluded that the plane exploded in the air.
Without traces
According to official figures, experts did not find traces of explosives in fragments scattered on the ground. “If you make an assumption that the remaining small details of the aircraft is a consequence of the explosion on board, then for this it is necessary to on board at least 10 kg of explosives,” says Vladimir Mikhailov, a former head of the explosive technology unit of the KGB of the USSR . -Information is not enough to draw any conclusions. This is hardly a terrorist attack. Everything is possible. But what if someone just transferred management? After all, there were several respected people aboard. The dispatcher then said that the pilot behaved inappropriately. ”
Inadequate plane
Talking about the inadequate behavior of the commander went after a telephone interview with the first channel of the dispatcher of the Perm airport Irek Bikbov. He said: “I have contacted him to another dispatcher, who controls just on this circle. He did not get in touch with that dispatcher, and the height began to fall sharply. And when the height was about 600, I heard a scream. I shouted to him: "Save 600." He did not answer it, and then after a second I heard a flash. And there, in one of the areas of the city, such an outbreak and glow. I realized that he had already fallen, and quickly began to declare the alarm. He did not have time to report anything. And he behaved inadequately. He did not execute the command. Perhaps something happened, but he did not want to report this. ”
The version that someone outsiders could manage the actions of the pilot is denied by the president of the trade union of the air traffic controllers Sergey Kovalev: "This provides for some actions that are recognized on Earth."
“Now they talk about the inadequate behavior of the pilot. But how was it caused? - argues Oleg Smirnov. - The devices from which he took readings could inadequately behave inadequately, because at that time of the day and in such clouds he could be guided only by the dashboard. Boeing, as a rule, lands in automatic mode. If there were any violations in the automatic system, then she could reduce the plane, even if the crew gave her a command to a set of heights. ”
The commission working at the place of the tragedy established that Boeing flew out of Moscow with a shut -off machine gun, that is, it was impossible to maintain speed in automatic mode. “The traction machine could at some point disconnect and not give gas. And the guys thought he gave. But we don’t know this yet, ”says Mikhail Markov.
Collision
Faced with the ground, the plane scattered into many fragments. The speed of the fall was very high, which one has yet to be found out. “As if it were not a plane, but a car,” says Oleg Smirnov. - This could happen for several reasons. First: the management refused, and the crew cannot do anything about it. Second: this is again automation, which, suppose, itself translated the engines instead of reducing revolutions and capacities to increase, up to the runway. ”
“We ourselves break our heads,” says Rafail Aptukov, vice -president of the flight safety partnership. - There is such a concept of “dumping”. It seems that the plane fell, that is, the angle of attack, for example, did not correspond to speed, the roll of the aircraft could step over the safety line. Why did he get into this situation? Thousands of versions can be. ”
Oleg Smirnov, President of the Civil Aviation Partner Foundation
There is no one to engage in civil aviation, a bacchanalia is going on here, there is no single state unit of its regulation. Now several departments are guided by this: a Ministry of Transport, the Federal Air Transport Agency, Rosaeronavigation, etc. And the seven nannies have a child without eye. No one is personal responsibility. Not a single hairs fall, no one to ask. And now the tragedy is investigating the Ministry of Transport, which means that the Ministry of Transport is investigating itself. In the USA, for example, there is a National Bureau of Flight Security, one of the functions of which is an independent investigation. Its leader is appointed by the President of the United States and reported only to the President and the Senate. Also, our Air Code is absolutely unsuitable, even the expressions are still absolutely Soviet. We do not have a law on airports. There are no heaps of federal aviation rules, which, incidentally, are recommended by IKAO. And the list can be continued. We are engaged in normation in the Ministry of Transport, but for this they do not give a bribe. And who will do this for the salary?
