The 1951 Aradan Aeroflot An-2 crash was an aviation accident that occurred on Saturday, April 21, 1951. An Antonov An-2 aircraft, operated by Aeroflot, on a flight from Kyzyl to Abakan, collided with a mountainside on the Abakan Ridge. All four crew members on board were killed.

Aircraft

[edit]

The Antonov An-2 (registration number CCCP-A2597, serial number 10647307) had been manufactured on January 28, 1951. It was delivered to the airline "Aeroflot" on March 7 of the same year.

Crew

[edit]
  • Captain — Sergey Stepanovich Puzyryov
  • First Officer — Leonid Filippovich Vasilyev
  • Navigator — Vasily Ivanovich Medvedev
  • Flight Engineer — Yuri Lukich Khmelnitsky

Investigation

[edit]

According to the findings of the investigation, the poor organization of the flight and inadequate management of the flight were highlighted as follows:

  • The aircraft was dispatched on a flight from Krasnoyarsk to Kyzyl outside of the schedule. The airports of Abakan and Kyzyl were not notified in time about this flight, its reception, servicing, and the aircraft involved.
  • All four deceased crew members had never flown the Abakan-Kyzyl route before, even as operational passengers.
  • The aircraft was dispatched from Abakan to Kyzyl and back according to a weather forecast that was below the established minimum.
  • Premature termination of communication with the aircraft on the command radio station and failure to use it for flight management within hearing range.
  • Violation by Commander Puzyryov of §§ 84 and 256 NPP-47, resulting in the aircraft, flying in snowfall, potentially icing up (including carburetor icing) and crashing into a mountain during a forced descent with limited visibility. It was also considered that a landslide of rock and snow might have occurred.

Poor meteorological support for the flight was identified due to the following reasons:

  • The weather forecast prepared by the Kyzyl AMSG did not predict wet snow, visibility up to 1 kilometer, and the covering of the Aradan Ridge by clouds.
  • A storm warning from the Olenya Rechka meteorological station was transmitted to the Kyzyl airport's ADS only 39 minutes after it was received via telegraph, preventing the aircraft from returning to the airport.
  • Lack of direct telephone communication between AMSG and the telegraph and poor interaction between the GMB and AMSG of Kyzyl.

Findings in 2009 and 2019

[edit]

In August 2009, blogger Sergey Shishkin and his group filmed the wreckage of CCCP-A2597 at the crash site. The video shows landing gear struts, the engine, and parts of the fuselage. The video was uploaded to YouTube on March 31, 2016, titled “Aradan 2009. 10th day.”

On June 9, 2019, a helicopter piloted by Alexey Kantsedalov discovered the wreckage of CCCP-A2597 at an altitude of 1,850 meters (200 meters from the landing site). Alexey saw the remains of the An-2 and, recognizing the first digits of the registration number, realized it was the very aircraft he had been searching for.

Found the engine number, found the aircraft number. I mapped out a route for myself because I didn't know the exact spot. Yes, the Aviators' Pass, but it's just marked on the map. There are no coordinates, nothing. We flew with my son. We had a flight to Abakan, made a detour to Ergaki. We flew and found this place. We landed there, and by the engine number and the first two digits of the registration number, we were able to identify that it was indeed that aircraft. And then we started looking for the relatives.
