A federal jury has convicted a 62-year-old South Florida man and Russian national on all 12 counts he faced for conspiring to illegally ship nearly $1 million worth of U.S. aircraft parts to Russia and its flagship carrier, Aeroflot. Alexander Mamonov, a former Aeroflot employee who relocated from Russia to South Florida, now faces sentencing on November 20 before U.S. District Judge Kathleen M. Williams in the Southern District of Florida.
Mamonov was found guilty after a federal trial of violating and conspiring to violate the Export Control Reform Act, smuggling goods, conspiracy to commit smuggling, submitting false or misleading export information, and conspiracy to commit money laundering, according to WPEC. Prosecutors said Mamonov conspired to acquire and ship more than $900,000 in aircraft parts to Russia and Aeroflot, and court documents and testimony showed he and co-defendant Ignat Vakorin used the United Arab Emirates and China as false destinations to conceal shipments actually bound for Russia. Federal prosecutors said the pair used false destinations and financial transactions to mask the true endpoint of the goods, and court records indicate Mamonov misled U.S. suppliers about where the parts were actually headed.
The prosecution was led by Assistant U.S. Attorney Sean Paul Cronin of the Southern District of Florida and Justice Department Trial Attorney Brett Ruff, following a joint investigation by the FBI's Miami Field Office and the U.S. Department of Commerce's Bureau of Industry and Security, according to the Tampa Free Press. Vakorin, who was indicted alongside Mamonov in April 2025 for helping orchestrate the illicit shipping routes, remains a fugitive outside the United States and is subject to an international arrest warrant, per CiberCuba.
Officials Warn Against Using South Florida as a Backdoor to Russia
Jason A. Reding Quiñones said a fake destination on a shipping label cannot make American export laws disappear, and added that Russia cannot evade American sanctions and export controls by routing its purchases through South Florida. Roman Rozhavsky said the verdict should serve as a warning to anyone considering smuggling U.S. technology to adversaries.
The case follows the U.S. Department of Commerce's broader tightening of export restrictions after Russia's 2022 invasion of Ukraine. The department issued a Temporary Denial Order barring Aeroflot from receiving U.S.-origin goods, first stripping the carrier of export privileges on April 7, 2022, and renewing that restriction annually through late 2024, according to the Federal Register. As of October 2025, similar Temporary Denial Orders remained active against Ural Airlines, Aeroflot, and Azur Air, according to the Washington Trade & Tariff Letter.
Why Russian Carriers Keep Turning to Illegal U.S. Parts
Western-built aircraft, mostly manufactured by Boeing and Airbus, make up roughly two-thirds of Russia's commercial airline fleet and carry about 90 percent of its total passenger traffic, the Washington Trade & Tariff Letter reports, creating severe pressure on Russian carriers to find replacement parts however they can. That demand has fueled a black market: an analysis of Russian customs data by trade intelligence firm Import Genius found that more than $14.4 million in restricted U.S. aircraft components, including $8.9 million in Boeing equipment, were illegally shipped into Russia during the first eight months after the 2022 invasion, according to Mind.ua.
Mamonov's case is not the first of its kind to emerge from South Florida. In April 2024, Miami-Dade County residents Oleg Patsulya and Vasilii Besedin pleaded guilty to federal export control conspiracy after using a network of Florida, Turkish, and Middle Eastern shell entities to supply Boeing 737 brake systems and other aviation components to Russian carriers. The pattern has continued into this year: Plantation businessman Maxim Larin admitted to smuggling gun parts to Russia after disguising export-controlled firearms components as household goods, pleading guilty in Brooklyn federal court in August.
Steep Penalties Loom at November Sentencing
Criminal violations of the Export Control Reform Act carry statutory penalties of up to 20 years in prison and up to $1 million in fines per count, along with administrative monetary penalties and total denial of export privileges, according to the Bureau of Industry and Security. With Mamonov convicted on all 12 counts, his exposure at the November sentencing could be substantial, though the exact sentence Judge Williams will impose remains unknown. It is also unclear whether authorities will be able to apprehend Vakorin, who remains at large abroad, or identify the specific American suppliers who were misled by the false shipping manifests.
