The Aeroflot export case led to the conviction of Alexander Mamonov, a 62-year-old Russian national living in Florida, on all counts following a jury trial over a scheme to illegally ship U.S. aircraft parts to Russia and state-owned carrier PJSC Aeroflot, according to federal officials.
Assistant Attorney General for National Security John A. Eisenberg said the verdict underscores the government’s commitment to enforcing export-control laws. He noted that the National Security Division, U.S. Attorney’s Offices, and law enforcement partners will continue to protect U.S.-controlled items from unlawful exports.
FBI Counterintelligence and Espionage Division Assistant Director Roman Rozhavsky said Mamonov exported nearly one million dollars in aviation components to Russia by deceiving U.S. suppliers about the parts’ destination. He said the FBI and its partners will prioritize enforcement of export rules and sanctions.
U.S. Attorney Jason A. Reding Quiñones for the Southern District of Florida said Russia cannot sidestep sanctions and export controls by routing shipments through South Florida. He said the defendant secretly funneled nearly $1 million in aircraft parts to Russia and Aeroflot and concealed the activity with false destinations and financial transactions. A federal jury found him guilty on every count.
Mamonov was convicted in the Southern District of Florida on 12 counts, including conspiracy to violate the Export Control Reform Act, illegal export of items subject to that law, conspiracy to commit smuggling, smuggling of goods, submitting false or misleading export information, and conspiracy to commit money laundering. U.S. District Judge Kathleen M. Williams set sentencing for Nov. 20.
Prosecutors said a federal grand jury indicted Mamonov in April 2025 along with Russian national Ignat Vakorin, who remains a fugitive.
Developments in the Aeroflot export case
According to court filings and testimony, after Russia expanded its invasion of Ukraine in early 2022, the Commerce Department tightened export restrictions on Russia and issued a temporary denial order prohibiting Aeroflot from receiving U.S.-origin goods. Mamonov, a former Aeroflot employee who moved from Russia to South Florida, conspired with Vakorin to procure and unlawfully ship more than $900,000 in aircraft parts to Russia and to Aeroflot. Officials said they misled U.S. suppliers by claiming the parts were destined for locations such as the United Arab Emirates and China.
The FBI’s Miami Field Office led the investigation with assistance from the Commerce Department’s Bureau of Industry and Security.
Assistant U.S. Attorney Sean Paul Cronin for the Southern District of Florida and Trial Attorney Brett Ruff of the National Security Division’s Counterintelligence and Export Control Section are prosecuting the case.
