Détails:
The Tu-134 jet was attached to the Voroshilovgrad Higher Military Aviation School of Navigators and operated on a flight from Zhdanov (now Mariupol) to Voroshilovgrad (now Lugansk). The school's commander was on board as a passenger.
Twelve minutes after takeoff, at height of 4200 m, strong oscillations in pitch and a roll occurred. The plane suffered big vertical and lateral loadings and descended to 2750 m. After 38 seconds it disintegrated in mid-air.
During repairs at a military maintenance facility, two wires on the electrical circuit of the back-up yaw damper had been cross-wired. The main yaw-damper performed uneventful. On the accident flight however the plane passed through a zone of strong turbulence. The back-up yaw damper then kicked in, sending wrong commands to the elevator and the ailerons.
