In one of the most significant aviation fraud cases in recent years, a former music industry figure was sentenced to four years and eight months in prison in London, UK, after selling tens of thousands of fake aircraft parts worth about £7 million to airlines around the world. According to reporting by The Guardian, the individual behind AOG Technics, 38-year-old Jose Alejandro Zamora Yrala, organized the scheme from an office registered in the United Kingdom, distributing components for CFM56 engines used on popular narrowbody aircraft, such as the Boeing 737NG and Airbus A320ceo. The fraud spanned several years and impacted operators across Europe and the United States. The sentencing, handed down on February 23, has once again raised serious questions about supply chain oversight in global aviation.
The scale of the case is staggering. Investigators found that more than 60,000 parts were sold with falsified documentation, allowing them to enter airline inventories as legitimate components. As detailed by FOX News, not only European carriers, such as Ryanair, but also some US carriers, including American Airlines in particular, were affected, forcing emergency inspections and aircraft groundings. The case has exposed vulnerabilities in the international trade of surplus and used aircraft parts, particularly in the high-demand CFM56 aftermarket.
Inside The AOG Technics Scheme
At the center of the scandal was AOG Technics, a UK-based supplier of aircraft spare parts. According to The Guardian, the company’s head falsified documentation to make used, counterfeit, or untraceable parts appear airworthy. Zamora Yrala used his home computer to create genuine certificates and false delivery records from manufacturers, even inventing fake employees and sending emails signed by nonexistent quality managers to give the paperwork credibility. Many of these components were intended for the CFM56, one of the most widely used turbofan engines in commercial aviation, which powers aircraft such as the Boeing 737 and the Airbus A320 families. The fraud was ultimately uncovered in August 2023 when an airline contacted the engine manufacturer to verify the authenticity of an AOG-supplied part.
Authorities determined that approximately 60,000 parts were distributed with forged airworthiness release certificates. These documents are critical in aviation, as they verify a component’s origin, maintenance history, and compliance with safety regulations. Without authentic paperwork, a part cannot legally or safely be installed on a commercial aircraft. The discovery forced airlines and maintenance organizations to trace and remove suspect components, triggering operational disruption across multiple fleets.
The total financial damage, exceeding £40 million, extended beyond the cost of replacing parts. Airlines faced flight cancellations, passenger reaccommodation expenses, and significant labor costs for maintenance. The ripple effects were particularly acute given the already strained global supply chain for aircraft components.
Why The Aircraft Parts Aftermarket Can Be Vulnerable To Fraud
The CFM56 engine family, produced by CFM International, is among the best-selling jet engine lines in history. With tens of thousands of units delivered since the 1980s, it powers a substantial portion of the world’s single-aisle fleet. This widespread use made the fraud especially impactful: any uncertainty about documentation could affect operators across multiple continents simultaneously.
The aviation aftermarket, where used serviceable material (USM) is bought and sold, is a legitimate and essential part of airline cost management. Airlines frequently purchase overhauled or surplus parts to reduce maintenance expenses. However, the AOG Technics case illustrates how the system relies heavily on trust, documentation, and traceability. When paperwork is falsified, the risk extends far beyond financial loss to potential safety concerns.
According to The Guardian, regulators and manufacturers were alerted after maintenance organizations identified inconsistencies in documentation. Once suspicions were confirmed, aviation authorities from various countries began coordinating with airlines to identify affected components. While no accidents were directly attributed to the fake parts, the incident triggered an urgent review of compliance processes across the industry.
The case also highlights the pressures facing airlines in the post-pandemic recovery era. With supply chains tight and turnaround times for new parts extended, demand for readily available components surged. That environment created opportunities for criminals to exploit gaps in documentation.

The AOG Technics case is not happening in isolation. During the same week as the London sentencing, authorities in Italy started an investigation into the disappearance of military aircraft parts valued at €17 million. According to Euronews, prosecutors are examining allegations of fake certifications and the resale of sensitive aviation components to customers in South America. A key part of the investigation is the creation of “out-of-use” certification for certain airworthy parts to be removed from the military warehouse, the elimination of traceability, and the illegal reintroduction of those parts elsewhere under another forged certification. The case reportedly involves parts originally meant for military platforms, including Lockheed C-130 Hercules, AMX and Panavia Tornado.
While the Italian investigation concerns military equipment and not commercial airliners, the underlying issue is similar: fraudulent documentation enabling unauthorized parts to circulate among aviation customers worldwide. As global fleets age and maintenance demand increases, oversight of spare parts supply chains is becoming more complex. Both cases underscore the importance of digital traceability systems and stronger international cooperation between regulators.
In the wake of the AOG Technics fraud, industry stakeholders are reassessing how parts certification is verified. There is now a growing discussion about improving blockchain-based tracking, enhancing audit requirements for parts brokers, and imposing stricter enforcement penalties to prevent similar situations.
