Incident Overview
On final approach to Chardzhou Airport, a Yakovlev Yak-40 experienced a loss of control at an altitude of 30-40 meters. The aircraft banked left, lost height, and crashed onto several dachas located in the approach path. The impact resulted in substantial damage to the aircraft, rendering it beyond repair. Despite the severity of the accident, all 35 occupants survived. The flight engineer sustained injuries. No injuries were reported on the ground.
Sequence of Events
The aircraft was on a standard approach when, at low altitude, it suddenly banked left and descended uncontrollably. The descent continued until the airplane struck multiple residential structures (dachas) situated beneath the approach path. The collision destroyed the aircraft and damaged the buildings.
Investigation Findings
The official investigation determined that the loss of control occurred due to wake turbulence generated by a Mil-Mi 6 helicopter that had been operating ahead of the Yak-40. The controller responsible for managing approaches failed to maintain the required minimum separation between the helicopter and the following aircraft. Additionally, poor organization of air traffic control (ATC) services in Turkmenistan was cited as a contributing factor.
Aftermath
Emergency services responded to the crash site. All occupants were accounted for, with only the flight engineer needing medical attention for injuries. The aircraft was a total loss. The dachas involved sustained damage but no casualties occurred on the ground.
