Russia's Interstate Aviation Committee (MAK) opened an investigation into the accident. A separate criminal investigation was opened to investigate allegations of breaching transport and fire safety rules. Both flight recorders were recovered and analysed. Russia's Ministry of Emergency Situations stated that the initial investigations pointed towards an electrical short circuit being the cause of the fire, which started in the central area of the fuselage, ahead of the rear-mounted engines.
