In a significant development for the aviation industry, the UK Serious Fraud Office (SFO) has charged Jose Alejandro Zamora Yrala, director of AOG Technics Ltd., with fraudulent trading of aircraft parts.
The charges stem from a high-profile investigation into the supply of thousands of aircraft spare parts with falsified documentation.
This scandal had a broad reaching effect across the global aviation sector. It has raised concerns about safety and trust in the supply chain.
The Allegations Against AOG Technics
The SFO alleges that between 2019 and 2023, AOG Technics defrauded airlines, maintenance providers, and parts suppliers. This involved the supply of aircraft components with fake certificates.
These parts were primarily for CFM56 engines used in older Airbus A320 and Boeing 737 aircraft. The “bogus parts” had falsified records regarding their origin, status, or condition.
While the parts were not critical to aircraft safety, their questionable authenticity led to widespread disruption. In 2023, airlines worldwide grounded planes after safety alerts from major aviation regulators. This included the UK Civil Aviation Authority (CAA), the US Federal Aviation Administration (FAA), and the European Union Aviation Safety Agency (EASA).
The SFO’s investigation revealed the scale of the fraud, which undermined confidence in the £34.5 billion UK aviation industry.
The agency claims AOG Technics’ actions misled customers into believing the parts were legitimate, posing potential risks to safety and economic stability.
No accidents or safety incidents were directly linked to the parts. However, the scandal forced airlines to inspect and replace components, causing costly delays.


SFO Response and Legal Proceedings
The SFO launched its investigation in December 2023, raiding Zamora Yrala’s London home and arresting him. The probe uncovered evidence of systematic fraud, leading to the recent charge of fraudulent trading.
Zamora Yrala is now set to appear at Westminster Magistrates’ Court on June 2, 2025, to face these allegations.
The SFO’s director has emphasized the agency’s commitment to protecting the aviation industry, which employs over 960,000 people in the UK and supports global connectivity.

Impact on the Aviation Industry
The AOG Technics case highlights vulnerabilities in the aviation supply chain, where trust in documentation is critical.
The falsified parts disrupted operations for airlines and maintenance firms, many of which rely on third-party suppliers for cost-effective solutions.
The scandal has prompted regulators and industry leaders to review certification processes and strengthen oversight to prevent similar fraud in the future.
Looking Ahead
As the case progresses, the aviation sector will closely watch the legal proceedings against Zamora Yrala. A conviction could lead to significant penalties, including imprisonment and fines, while also serving as a deterrent to fraudulent practices in the industry.
This case serves as a reminder for the industry to tighten controls and restore confidence in the global supply chain. For now, stakeholders await further developments as the court date approaches.
