Incident
On an unspecified date, a single-engine airplane operating as flight SU397 from Tyumen to Tavda was approaching Tavda from the south. The aircraft carried 13 passengers and two pilots. At the same time, an Aeroflot PZL-Mielec AN-2TP registered CCCP-44992 had just departed Tavda Airport minutes earlier on a service from Tavda to Tyumen, with 14 people on board. While at an estimated altitude of 175 meters, the two aircraft collided in mid-air.
Weather Conditions
The crew of flight SU397 encountered marginal weather conditions during their approach. Reports indicated rain, limited visibility of 2 km, and low clouds.
Collision and Crash
Following the collision, both aircraft lost control, entered a dive, and crashed in flames in an open field located 18 km south of Tavda. The wreckages were found 392 meters apart. All 29 occupants on both aircraft were killed.
Investigation
The official investigation determined the probable cause of the accident. The in-flight collision was the consequence of a lack of ATC assistance and the fact that both crews were flying under VFR mode in adverse weather conditions.
