A Florida resident and Russian national, Alexander Mamonov, 62, was convicted on all charges following a jury trial related to a scheme to illegally export aircraft parts from the United States to Russia and the state-owned Russian airline, PJSC Aeroflot.
“This guilty verdict – on all counts – shows the United States government’s resolute commitment to upholding our export-control laws and to prosecuting those who violate them,” said Assistant Attorney General for National Security John A. Eisenberg. “The National Security Division and our U.S. Attorney’s Offices and law enforcement partners will continue to safeguard U.S.-controlled items from being exported unlawfully.”
“Mamonov illegally exported nearly one million dollars of aviation parts to Russia by lying to U.S. suppliers about their destination, and this conviction on all counts holds him accountable,” said Assistant Director Roman Rozhavsky of the FBI’s Counterintelligence and Espionage Division. “The FBI and its partners will continue to prioritize the enforcement of export laws and sanctions to defend the homeland. Let this verdict serve as a warning to anyone considering smuggling U.S. technology to our adversaries.”
“Russia cannot evade American sanctions and export controls by routing its purchases through South Florida,” said U.S. Attorney Jason A. Reding Quiñones for the Southern District of Florida. “You cannot put a fake destination on a shipping label and make American export laws disappear. This defendant conspired to secretly funnel nearly $1 million in American aircraft parts to Russia and Aeroflot, then used false destinations and financial transactions to conceal what he was doing. A federal jury held him accountable on every count. We will continue to aggressively pursue those who use our district, our financial system, or American businesses to undermine U.S. national security.”
Mamonov was convicted in the Southern District of Florida of 12 counts related to that scheme, including conspiracy to violate the Export Control Reform Act (ECRA), illegal export of items subject to ECRA, conspiracy to commit smuggling, smuggling of goods, submitting false or misleading export information, and conspiracy to commit money laundering. U.S. District Court Judge Kathleen M. Williams scheduled sentencing for Nov. 20.
The defendant was charged by indictment in April 2025, alongside Ignat Vakorin of Russia. Vakorin remains a fugitive in wanted status.
Following Russia’s further invasion of Ukraine in early 2022, the U.S. Department of Commerce increased restrictions on exports to Russia and issued a temporary denial order barring Aeroflot from receiving U.S.-origin goods. According to court documents and testimony, Mamonov is a former Aeroflot employee who relocated from Russia to South Florida. After the U.S. Department of Commerce increased restrictions on Russian exports, Mamonov conspired with Vakorin to acquire and illegally ship over $900,000 in aircraft parts to Russia and to Aeroflot. Mamonov and Vakorin misled U.S. suppliers into believing the parts were being sent to other destinations, such as the United Arab Emirates and China.
This case was investigated by the FBI Miami Field Office with assistance from the U.S. Department of Commerce’s Bureau of Industry and Security.
