The Yakolev Yak-40 departed from Rostov-on-Don Airport at 12:47 Moscow time and proceeded on the route to Kerch. The air traffic controller in charge of the Western section of Krasnodar had been working for more than six hours by 13:30:44, the time the Yak-40 entered his sector of airspace while at an altitude of . After receiving confirmation from the controller the Yak-40 continued the flight path and reported passing the Novodmitrievskaya non-directional beacon at 13:34 and remained at an altitude of 5,700 metres. After passing that point the flight was supposed to decrease altitude in accordance with the flight plan, but the controller was busy managing other flights so he let the flight continue on to the Gelenjik-Kerch part of the route at the 5,700-meter altitude. At 13:43 the Yak-40 reported passing Gelendzhik and stated its altitude to be 5,700 metres, to which the controller responded by granting it permission to proceed with the Anapa transverse but yet again forgot to instruct the aircraft to change altitude. The Antonov An-24 took off from Donetsk Airport at 12:56 for its flight to Sochi. At 13:32, the crew reported entering the Western section of Krasnodar on the Primorsko-Akhtarsk route at an altitude of 5,700 meters, which was the same altitude as the Yak-40 in that section of airspace. The controller responded by permitting the An-24 to proceed to Anapa and keep the current altitude, then gave permission for the aircraft to continue on to Dzhubga without changing altitude. At 13:51:05 Moscow time, the An-24 and Yak-40 collided in the air at an altitude of 5,700 meters, severing the tail sections of both aircraft. Both aircraft broke apart in mid-air and the wreckage fell into the Black Sea. All 70 people in the two aircraft were killed in the accident. The wreckage of the An-24 and the tail section of the Yak-40 were found in the Black Sea at a depth of . Most of the dead from the An-24 were recovered from the water but no bodies from the Yak-40 were found nor was the fuselage of the Yak-40 recovered.Causes
The cause of the accident was determined mostly from radio and ground communications. The primary cause of the accident was described as a violation of the rules for maintaining separation between aircraft by the air traffic controller. Secondary causes of the accident were failure of both crews to remain sufficiently alert and a lack of appropriate situational analysis leading up to the accident.References
