What happened
During the final approach phase at Chardzhou Airport, a Yak-40 was flying at an altitude of approximately 30 to 40 meters when the aircraft experienced a left bank. This maneuver led to a rapid loss of altitude, causing the plane to strike several datchas situated along the approach path. While the impact resulted in the aircraft being destroyed beyond repair, all 35 occupants on board survived the incident. One injury was reported involving the flight engineer, though no individuals on the ground sustained any harm.
Findings
Investigations into the accident concluded that the loss of control during short final was triggered by wake turbulence. This turbulence was generated by a Mil-Mi 6 helicopter that had been flying ahead of the aircraft. The investigation identified that the air traffic controller managing the approaches did not maintain the required minimum separation between the helicopter and the Yak-40. Additionally, systemic issues regarding the organization of air traffic control services in Turkmenistan were noted as a contributing factor to the event.
