plane

The aircraft used on the flight was an Antonov An-12BK from Soviet production that was 40 years and a month old at the time of the accident. The machine was rolled out on March 6, 1968. It had the factory number 88345508 and the model serial number 55-08 . The machine completed its first flight on March 31, 1968, the delivery to Aeroflot with the aircraft registration number CCCP-12957 followed on April 25, 1968. During the Soviet era, the machine was passed on between different local departments of Aeroflot. On May 12, 1981, there was an accident with the machine in Anadyr , and another on December 18, 1992, when the machine rolled over the end of the runway in Norilsk after an aborted start . After that, the machine was stored for some time , also due to the collapse of the Soviet Union , before it was repaired again and put into operation by the local government of Norilsk. The Antonow received its new, Russian registration number RA-12957 and went back into service on November 22, 1995. From December 8, 1995, the aircraft was leased to the Yenisei Meridian airline before it was put into storage on March 23, 1998. From November 25, 1998, the machine was used again by the regional government of Norilsk, before the machine was put into storage again on January 15, 2001. From April 23, 2001, it was back in service. On October 10, 2001, the machine was sold to the leasing company Gals-Inter , which immediately leased it back to the Norilsk government. From August 28, 2001, the aircraft was leased to Kosmos Airlines until the airline put it into storage again on May 24, 2006. On July 20, 2006, it was put into operation again, until another storage followed on April 24, 2008. Only three weeks before the accident, on May 5, 2008, the machine was put into operation at its new owner, Moskovia Airlines. The four-engine transport aircraft was equipped with four turboprop engines of the type Ivchenko AI-20M equipped. At the time of the accident, the machine had a cumulative operating performance of 43,759 operating hours, which accounted for 14,828 take-offs and landings. At the time of the accident, the plane was painted by Kosmos Airlines, only the operator logos had been painted over.

Inmates and cargo

There was a crew of seven on board, and two passengers flew with it. The flight captain Anatoly Stepanowitsch Sereschkin had 14,928 hours of flight experience, the first officer Alexei Nikolayevich Volkov had 11,021 hours. Other inmates included the navigator Oleg Yossifowitsch Sevastianow, the flight mechanic Alexander Wassilijewitsch Pashkow, the radio operators Viktor Serafimowitsch Tjumenzjew and Juri Nikolajewitsch Bogdan, the flight manager Andrej Nikolajewitsch Makarow and the two engineers Yuri Walentisowitsch Tjukenko.

the accident

Freight had been delivered to Chelyabinsk with the machine. The machine was on its return flight to Perm. The aircraft took off from runway 09 at 14:03 UTC. About one minute after take-off, the crew reported smoke in the cockpit. The pilots asked for permission to return to landing on runway 09. During the return flight and the alignment of the machine according to runway 09, smoke increasingly filled the cockpit. The crew also received several false warnings. Then two engines were automatically shut off. The aileron control was lost about 11 kilometers from the destination airport and with it control of the machine. The Antonov hit the ground and burned out.

root cause

A loss of controllability with regard to the roll angle of the machine was found to be the cause of the accident. The loss of control occurred due to the fire-related destruction of the aileron control cables during an emergency approach to the Chelyabinsk airport. The aileron cabling was probably destroyed in the area of ​​the 23rd to 25th stringer of the cargo hold. The reason for the destruction of the cabling system was most likely a considerable heat effect from a control shaft located in this area and its subsequent break under tensile load operation. The heating of the control shaft was probably the result of a fire in the neighboring on-board power supply. This led to smoke development in the cargo hold, an unexpected triggering of alarm systems, a failure of the control systems and the automatic shutdown of two engines. Electrical cable ladders, distributors and other assemblies in the area of ​​the 15th to the 25th stringer, i.e. the ceiling of the hold, were severely affected by the fire, which led to a collision with the floor. Due to the severe fire and fall damage, it was not possible to precisely determine the original source of the fire.
