Investigation Summary
The flight departed Baku for Grozny and was cruising when the crew declared an emergency, reporting to air traffic control that the aircraft had become uncontrollable. They initiated a diversion to the nearest suitable airport, Aktau in Kazakhstan. During the emergency approach, the aircraft impacted the ground twice, coming to rest approximately 1.5 km from the runway threshold. The fuselage broke into two main sections, and a post-crash fire erupted. Emergency services responded, but there were numerous fatalities. An investigation was immediately launched by Kazakhstan's Ministry of Transport, with participation from Azerbaijan's Interstate Aviation Committee (IAC) and Brazilian authorities.
Final Conclusions
The investigation is being conducted by the Ministry of Transport of Kazakhstan with the participation of the Interstate Aviation Committee (IAC). The final report has not yet been released. The flight data and cockpit voice recorders were recovered in good condition and are being analyzed to determine the sequence of events and the root cause of the loss of control.

Systems & Failure Modes
Fly-by-Wire (FBW) Flight Controls
The Embraer E190 utilizes a FBW system where pilot inputs are sent as electronic signals to flight control computers, which then command actuators to move the control surfaces. A failure in this complex system is a key focus of the investigation due to the crew's report of an uncontrollable aircraft.
Flight Recorders (Black Boxes)
The CVR and FDR were recovered from the wreckage. Their data is critical for investigators to reconstruct the flight's final moments, understand the nature of the control failure, and analyze the crew's actions.
Emergency Diversion
The crew correctly identified a critical in-flight issue and initiated a diversion to the nearest suitable airport, a standard emergency procedure. The investigation will examine the decision-making process during the diversion.
