On Friday, November 1, 1974, an Antonov An-2 single-engine biplane and an Mil Mi-8 helicopter collided near Surgut airport, killing all 38 people on board both aircraft.[1]

Aircraft involved

The An-2 serial number 1G132-21 was registered USSR-70766 and was certified for operation on November 4, 1971. The airframe had a total operating time of 2,591 flight hours with 3,477 landings.[2]

The Mi-8T serial number 3771 was registered USSR-25686 and was certified on June 8, 1973. The total operating time of the helicopter was 1,298 hours with 3,416 landings.[2]

Accident

The An-2 was operating as flight 662, a passenger service from Khanty-Mansiysk to Surgut and departed at 11:36 Moscow time with 2 crew members and 12 passengers. At 12:54, the Mi-8 took off from Surgut airport, despite the fact that the weather conditions were below its meteorological minimum. The An-2 was approaching Surgut airport on a heading of 253 degrees in instrument meteorological conditions conditions, then turned to a heading of 73 degrees to land. The helicopter was leaving the airport on a heading of 220 degrees and at 12:56:36 (14:56:36 local time), approximately 4.5 km southwest of Surgut airport at an altitude of 150 meters the aircraft collided.[2]

Investigation

The main cause of the accident was the unsatisfactory management of the air traffic zone of Surgut airport. In the conditions of poor visibility, approach procedures were violated and dispatchers released and received aircraft despite the fact that meteorological minimums for these types were not met. A contributing factor was the lack of control over the movement of aircraft by radar and poor radio communication.[2]
