Incident Overview
A group of seven PZL-Mielec AN-2 aircraft were being transferred from Urgench, Uzbekistan, to Myashkovo, with intermediate stops in Uralsk and Penza. The aircraft carried mechanics and crew members. En route from Uralsk to Penza, while cruising at an altitude of 500 meters, two of the aircraft, registered CCCP-28938 and CCCP-32112, entered a cloudy area with light rain. They collided, then entered a dive and crashed in flames 350 meters further, coming to rest 25 meters from each other. Both aircraft were totally destroyed, and all 10 occupants were killed.
Flight Conditions
The aircraft were operating under visual flight rules (VFR) in adverse weather conditions. The exact time of day was not specified in the source.
Probable Cause
According to the official investigation, the probable cause was poor flight preparation and planning, as all crew and the people in charge of the mission failed to analyze weather conditions en route. The collision occurred while both crews were flying under VFR mode in adverse weather conditions.
