Quick summary
A federal jury in Miami convicted Alexander Mamonov, a 62-year-old Russian national living in Florida, on all 12 counts in a scheme to illegally export U.S. aircraft parts worth roughly $1 million to Aeroflot in violation of post-2022 export controls. The August 28, 2026 verdict, confirmed in a U.S. Department of Justice press release, covers charges including conspiracy to violate the Export Control Reform Act, smuggling, false export filings, and money-laundering conspiracy.
Co-defendant Ignat Vakorin, also a Russian national, remains a fugitive. Sentencing is set for November 20, 2026, before Judge Kathleen M. Williams in the Southern District of Florida.
The verdict arrived four years into the U.S. government’s sustained effort to keep Western aviation technology out of Russian hands. Mamonov, a former Aeroflot employee, purchased aircraft components from American suppliers and arranged their shipment through intermediary addresses in the United Arab Emirates and China — paperwork designed to hide that the parts were ultimately bound for Russia’s state-owned carrier.
It did not work. The FBI Miami Field Office, with assistance from the U.S. Department of Commerce’s Bureau of Industry and Security, tracked the scheme and built the case that a jury unanimously accepted on August 28.
The practical consequence for Mamonov: conviction on a dozen federal charges, with sentencing scheduled for late 2026. His co-defendant, Ignat Vakorin, was indicted alongside him in April 2025 and has not been apprehended. The case number is 25-cr-20174.
For airlines, maintenance firms, and parts brokers operating anywhere near Russia-adjacent supply chains, the message from U.S. Attorney Jason A. Reding Quiñones was direct: routing purchases through South Florida or listing false shipping destinations does not dissolve U.S. export-law obligations. Assistant Attorney General for National Security John A. Eisenberg added that the verdict reflects the government’s commitment to prosecuting these violations and protecting U.S.-controlled items from unlawful diversion.
How the scheme worked — and why the charges stack up
Mamonov’s indictment covered six distinct legal theories, each targeting a different layer of the operation. Conspiracy to violate the Export Control Reform Act and the underlying illegal export charges address the core act of moving controlled goods without authorization. The smuggling counts cover the physical movement of goods under false pretenses. False export information charges target the fraudulent shipping documents. Money-laundering conspiracy addresses how proceeds from the scheme were handled.
Stacking charges this way is deliberate federal prosecution strategy — each count carries its own sentencing exposure, and conviction on all 12 leaves the judge with significant discretion at the November 20 hearing.
The Bureau of Industry and Security placed Aeroflot under a Temporary Denial Order on April 7, 2022 — weeks after Russia’s full-scale invasion of Ukraine — barring the airline from any transaction involving items subject to the Export Administration Regulations. That order has been renewed annually, with extensions confirmed in 2023, 2024, and 2025, making clear that BIS treats aviation sanctions as a long-term constraint rather than a temporary measure. Mamonov’s alleged conduct occurred entirely within this restricted period.
| Charge category | Specific count(s) | Governing law |
|---|---|---|
| Export control violations | Conspiracy + illegal export | Export Control Reform Act (ECRA) |
| Smuggling | Conspiracy + smuggling of goods | 18 U.S.C. § 554 |
| False export information | Submitting false/misleading data | Export Administration Regulations |
| Money laundering | Conspiracy to commit money laundering | 18 U.S.C. § 1956 |
| Scheme value | ~$1 million in U.S.-origin aircraft parts | Aeroflot as alleged end-user |

Why Russian carriers keep trying — and why it keeps failing
Aeroflot is not alone in facing these restrictions. BIS has issued Temporary Denial Orders against at least four other Russian carriers — Azur Air, UTair, Rossiya, and Aviastar — since 2022, effectively cutting entire fleets off from U.S.-origin components, not just individual shipments. The BIS enforcement actions against Russian airlines represent a coordinated administrative campaign running in parallel with criminal prosecutions like this one.
The underlying pressure driving schemes like Mamonov’s is straightforward. Russian carriers still operate significant numbers of Airbus and Boeing aircraft — jets engineered around a continuous supply of Western-sourced parts. Without those parts, airlines face a choice between cannibalizing grounded aircraft, sourcing from non-U.S. supply chains, or finding covert channels. The conviction demonstrates what the third option costs.
Transshipment through the UAE and China is not incidental. Both countries host dense trading and logistics networks that can obscure ultimate recipients, and U.S. authorities have made clear they scrutinize shipments routed through either jurisdiction when sanctioned actors are plausibly in the background. Routing paperwork through a Dubai or Shanghai intermediary does not shift jurisdiction — U.S. export law follows the origin of the goods, not the address on the shipping label.
Steps for compliance teams and affected travelers
The Mamonov conviction raises the legal floor for anyone in the aircraft-parts supply chain with Russia-adjacent exposure — and the DOJ has signaled it is actively looking for similar schemes.
- Parts suppliers and brokers: Review end-user documentation for any transaction where the ultimate destination is unclear. A UAE or Chinese intermediary address is not sufficient due diligence if the goods are U.S.-origin and the supply chain touches Russia. The DOJ and BIS have published guidance on red flags for diversion — consult it before approving Russia-adjacent orders.
- MROs and leasing firms: Verify that no counterparty in your supply chain is subject to a current BIS Temporary Denial Order. Aeroflot’s TDO has been renewed continuously since April 2022; transacting with a TDO-listed entity, even unknowingly, creates criminal exposure.
- Travelers planning Russia itineraries: Confirm your carrier is not subject to U.S. export restrictions or airspace bans before booking. Route through neutral hubs — Istanbul, Dubai, Almaty — on non-Russian airlines to avoid operational uncertainty tied to fleet maintenance constraints.
- Legal and compliance counsel: The 12-count conviction structure in this case — layering ECRA, smuggling, false filing, and money-laundering charges — signals that prosecutors are building maximum sentencing exposure into Russia export cases. Treat any Russia-adjacent parts transaction as requiring the same scrutiny as a direct export to a sanctioned entity.
Watch: Mamonov’s sentencing on November 20, 2026 will establish a concrete penalty benchmark for this category of export-control violation — the sentence Judge Williams imposes will signal how aggressively federal courts are treating aviation-parts diversion to Russia.
Questions? Answers.
What is a Temporary Denial Order, and does Aeroflot still have one?
Yes. The Bureau of Industry and Security placed Aeroflot under a Temporary Denial Order on April 7, 2022, barring it from any transaction involving items subject to U.S. Export Administration Regulations. The order has been renewed annually — with extensions confirmed in 2023, 2024, and 2025 — and remains in force. Any U.S.-origin goods, including aircraft parts, cannot legally be exported to Aeroflot while the TDO is active.
What sentence does Alexander Mamonov face?
Sentencing is scheduled for November 20, 2026, before Judge Kathleen M. Williams in the Southern District of Florida. Each of the 12 counts carries its own statutory maximum, and conviction on all counts — including money-laundering conspiracy — leaves the judge significant discretion. No specific sentencing range has been publicly stated ahead of the hearing.
Is co-defendant Ignat Vakorin likely to be arrested?
Vakorin was indicted in April 2025 and remains a fugitive as of the August 2026 verdict. The DOJ has not publicly confirmed whether an Interpol notice or extradition request has been filed. Fugitive co-defendants in export-control cases sometimes surface years later through international law-enforcement cooperation, but no timeline has been indicated in this case.
Does this case affect travelers flying through the UAE or China?
Not directly. The UAE and China appear in this case as alleged transshipment points used to disguise the parts’ final destination — not as countries whose aviation systems are implicated. Travelers transiting Dubai or Shanghai face no additional restrictions as a result of this verdict.
