Investigation Summary
The accident was initiated by a 'map shift' error where the aircraft's navigation system was displaced by approximately 4 km, leading to an unstable approach. During the subsequent go-around, the crew failed to realize that the autopilot had disconnected upon the activation of the Take-Off/Go-Around (TOGA) mode. The high engine thrust created a significant pitch-up moment, reaching 25 degrees. As airspeed decayed, the captain, likely suffering from a somatogravic illusion in the dark, overcast conditions, pushed the yoke forward aggressively. This resulted in a -75 degree nosedive. The investigation highlighted systemic failures in Russian aviation oversight, including the revelation that Captain Salikhov had never received proper primary flight training and had transitioned from a navigator role using fraudulent credentials.
Final Conclusions
The Interstate Aviation Committee (IAC) concluded the crash was caused by systemic deficiencies in safety management and regulatory oversight, which allowed an unqualified crew to operate the flight. The immediate cause was the crew's failure to recognize the autopilot disconnection and their subsequent inability to recover from a nose-up upset, leading to spatial disorientation and a fatal dive. Contributory factors included the crew's lack of English proficiency, which hindered their ability to understand training manuals, and the accumulation of fatigue due to violations of work and rest schedules.

Crew Experience
Captain
Former navigator; license obtained via falsified documents. Had 527 hours as Pilot-in-Command on type.
First Officer
Former aircraft mechanic and flight engineer.
Systems & Failure Modes
Inertial Reference System (IRS)
Experienced a 'map shift' error of 4 km, leading to the initial navigational deviation.
Autopilot
Disconnected automatically when the TOGA switch was pressed, a fact the crew failed to notice.
Elevator Controls
Subject to an alternative opinion by one investigator who suggested a possible mechanical malfunction, though this was not supported by the majority of the commission.
Interesting Facts
- 01The captain had previously served as a navigator and the first officer as a flight engineer and aircraft mechanic.
- 02The aircraft impacted the ground between the runway and the main taxiway, approximately 1,850 meters past the runway 29 threshold.
- 03One of the passengers was the son of the President of the Republic of Tatarstan.
- 04The captain's pilot certificate was found to have been issued based on falsified documents.
- 05The aircraft (MSN 24785/1882) was 23 years old and had previously been operated by several airlines including Air France and Uganda Airlines.
Safety Actions & Advisories
Revocation of Air Operator Certificate
Russia's Federal Air Transport Agency revoked Tatarstan Airlines' operating certificate in December 2013 following the accident.
Pilot Certification Audit
The accident led to a massive audit of Russian pilot licenses, resulting in the revocation of hundreds of certificates found to be fraudulent or improperly issued.
Criminal Prosecution of Airline Officials
In 2019, the Investigative Committee of Russia completed its criminal probe, leading to the sentencing of airline officials for their roles in the systemic safety failures that allowed the unqualified crew to fly.
Temporary Suspension of Boeing 737 Certificates
In November 2015, the Interstate Aviation Committee (IAC) briefly suspended the flying certificates of all Boeing 737s in Russia due to a dispute with Rosaviatsiya regarding elevator control safety.
Known Controversies & Unanswered Questions
Elevator Malfunction Theory
Reference ↗A member of the IAC commission filed an alternative opinion claiming the investigation ignored a possible mechanical failure of the elevator controls, though the official report maintained pilot error was the cause.
