Investigation Summary
The aircraft arrived at Sochi from Chkalovsky Airport for a refueling stop before its final leg to Syria. Investigation into the pre-flight phase revealed that Captain Roman Volkov exhibited signs of disorientation even before takeoff, reportedly experiencing difficulty with taxiing and identifying the correct runway. At 05:27 local time, the flight departed Runway 24 into the darkness over the Black Sea. Approximately 70 seconds into the flight, the aircraft began a series of erratic maneuvers. The investigation revealed that the Captain likely experienced a somatogravic illusion, a form of spatial disorientation where the physical sensations of acceleration are misinterpreted as a pitch-up attitude. In response to this false sensation, the pilot pushed the control column forward while the aircraft was still in a climb. This action, combined with a lack of effective monitoring by the other crew members, caused the aircraft to descend rapidly and impact the water at a high speed and steep bank angle.
Final Conclusions
The Russian Ministry of Defence concluded that the crash was caused by the pilot's spatial disorientation (human factors). The crew failed to maintain situational awareness during a night departure over water, a condition known to lack external visual references. No evidence of technical malfunction, fire, or external interference (terrorism) was found. The aircraft's weight and balance were within limits, and the fuel quality was confirmed to be satisfactory.

Airframe & Maintenance
Crew Experience
Captain
Roman Volkov, 35 years old. Reported to have over 3,000 flight hours.
Systems & Failure Modes
Flaps/Slats Control
Early reports suggested a possible retraction error or asymmetry, but this was later superseded by findings of pilot disorientation.
Flight Data Recorder
Located in the tail section, the FDR provided critical data showing the pilot's nose-down inputs during the climb.
Interesting Facts

Safety Actions & Advisories
Tu-154 Fleet Grounding
The Russian military temporarily grounded all Tu-154 aircraft following the crash until the initial investigation ruled out a systemic technical failure.
Spatial Disorientation Training
Recommendations were made to enhance training for military pilots regarding the risks of somatogravic illusions during night takeoffs over featureless terrain or water.
