It resulted in £39.3 million ($89m) in losses for airlines, including American Airlines and Ethiopian Airlines, as well as manufacturers.
Zamora Yrala was the sole director and shareholder of the company.
He pleaded guilty in December to a single count of fraudulent trading, an offence that carried a maximum sentence of 10 years.
He ran the operation from his home office in Surrey, southeastern England, buying parts such as engine blades, bolts and washers and selling them to airlines using forged authenticity certificates.
Prosecutors said about 90% of AOG Technics’ revenue relied on fraudulent documents.
Judge Simon Picken described his actions as “a complete undermining of the regulatory framework designed to safeguard the millions of people who fly every day, every year”.
The bulk of the financial losses were attributed to American Airlines, which did not purchase the parts directly but sourced them through suppliers.
“Zamora’s operation risked public safety on a global scale in a way that defies belief,” said Emma Luxton, director of operations at the Serious Fraud Office, which brought the charges.
AOG had supplied parts for the world’s best-selling passenger aircraft engine, CFM56, and most-used cargo aircraft engine, CF6, for almost a decade.
CFM56 engines are used on the Airbus A320 and Boeing 737 aircraft.
