Jat Tehnika is a Serbian aerospace company for Aircraft Maintenance, Repair and Overhaul. The company is based at Belgrade Nikola Tesla Airport and provides maintenance services for Air Serbia (the former Jat Airways), as well as other airlines across Europe.

Jat Tehnika is certified to provide full maintenance on Boeing 737 Classic and Next Generation family, as well as ATR 42 and 72 aircraft. The company got certification to maintain Airbus A320 family in 2013.


The origins of Jat Tehnika date back to the creation of Aeroput in 1927.

The first technicians and mechanics started working as pioneers of this profession in 1927. Jat Airways as a company was founded in 1947 (as the successor of Aeroput), and in 1963 the jet-engine fleet was introduced. The first wide body DC-10 aircraft arrived in 1978, followed by the new technology aircraft 737-300 in 1984.

In 2005 employees of the company launched a strike which paralysed the national airline Jat Airways for a month. Jat Technics were unhappy with their working conditions and pay.[2] In order to continue safe transportation of passengers Jat Airways brought North African technicians to Belgrade Nikola Tesla Airport which further angered the workers of Jat Tehnika seeing that their needs were being ignored.[3] The government of Serbia which wholly owns Jat Airways, separated Jat Tehnika from the parent company in 2006, to resolve the dispute.

Jat Tehnika received its JAR 145 certificate from the European Aviation Safety Agency (EASA) allowing the company to maintain all aircraft from the European Union in 2005. The company obtained a certificate from the American Federal Aviation Administration (FAA) to service airlines from the United States in 2007.[4]
