Florida, United States: A former Aeroflot employee, Alexander Mamonov, 62, was convicted on all 12 counts for his role in a scheme to illegally export more than $900,000 worth of U.S.-origin aircraft parts to Russia and Russian state-owned airline PJSC Aeroflot, the U.S. Department of Justice said on August 28, 2026.
The conviction followed a federal jury trial in the Southern District of Florida on August 27. Mamonov was found guilty of charges including conspiracy to violate the Export Control Reform Act (ECRA), illegally exporting items subject to ECRA, conspiracy to commit smuggling, smuggling goods, submitting false or misleading export information and conspiracy to commit money laundering. U.S. District Court Judge Kathleen M. Williams scheduled Mamonov’s sentencing for November 20, 2026.
According to court documents and testimony cited by the DOJ, Mamonov was a former Aeroflot employee who relocated from Russia to South Florida. He allegedly worked with Ignat Vakorin from Russia after the U.S. tightened export restrictions on Russia following its further invasion of Ukraine in early 2022. Vakorin was also indicted in April 2025 and remains a fugitive.
The DOJ said Mamonov and Vakorin obtained aircraft parts from U.S. suppliers and arranged for them to be shipped to Russia and Aeroflot despite U.S. restrictions. The pair allegedly misled U.S. suppliers about the actual destinations, claiming that the parts were being sent to countries including the United Arab Emirates and China rather than Russia.
The scheme involved aircraft parts worth more than $900,000. 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 prohibiting Aeroflot from receiving U.S.-origin goods.
Assistant Attorney General for National Security John A. Eisenberg said the verdict demonstrated the U.S. government’s commitment to enforcing export controls.
“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,” Eisenberg said. “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.”
FBI Assistant Director Roman Rozhavsky of the Counterintelligence and Espionage Division said Mamonov had exported nearly $1 million in aviation parts by lying to U.S. suppliers about their destination.
“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,” Rozhavsky said. “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.”
U.S. Attorney Jason A. Reding Quiñones for the Southern District of Florida said the scheme attempted to circumvent U.S. sanctions and export controls by routing purchases through South Florida.
“Russia cannot evade American sanctions and export controls by routing its purchases through South Florida,” Quiñones said. “You cannot put a fake destination on a shipping label and make American export laws disappear.”
He added that Mamonov had conspired to secretly funnel nearly $1 million in American aircraft parts to Russia and Aeroflot while using false destinations and financial transactions to conceal the operation.
“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,” Quiñones said. “Yesterday, 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 charged by indictment in April 2025 alongside Ignat Vakorin of Russia. Vakorin remains a fugitive in wanted status.
The case was investigated by the FBI Miami Field Office with assistance from the U.S. Department of Commerce’s Bureau of Industry and Security (BIS). Assistant U.S. Attorney Sean Paul Cronin of the Southern District of Florida and Trial Attorney Brett Ruff of the Justice Department’s National Security Division’s Counterintelligence and Export Control Section are prosecuting the case.
The U.S. Department of Justice published the press release on Friday, August 28, 2026, under Press Release No. 26-995. The release was issued by the Office of Public Affairs and categorized under National Security.
