Investigation Summary
The aircraft, a Brazilian manufactured Embraer Legacy 600, was operating a domestic flight from Moscow to Saint Petersburg. Flight tracking data indicated the jet reached an altitude of 28,000 feet before experiencing erratic altitude excursions starting at 15:19 UTC. The aircraft climbed to 30,100 feet, descended to 27,500 feet, and climbed again to 29,300 feet before a final, rapid descent. Eyewitness video captured the aircraft descending in a flat spin, trailing smoke, with one wing and the tail assembly visibly detached from the fuselage. Debris was found at three distinct sites, including a wing found 3km from the main fuselage, confirming an in-flight structural failure. While the Russian Investigative Committee launched a criminal case into violations of air safety rules, the investigation was marked by a lack of international cooperation. Russia declined an offer of assistance from Brazil's CENIPA, citing the domestic nature of the flight. In October 2023, President Vladimir Putin suggested that hand grenade fragments were found in the bodies of the victims and implied that the explosion may have been caused by the occupants themselves, though no formal civil aviation report was released to substantiate these claims.
Final Conclusions
The investigation remains under the jurisdiction of the Investigative Committee of Russia. As of late 2023, no final accident report has been published. The Russian Interstate Aviation Committee (IAC) is not leading the probe, and international observers have not been granted access to the evidence. The preliminary findings released by Russian officials suggest an internal explosion, but the specific mechanism and intent remain officially unconfirmed.
