The origins of Jat Tehnika date back to the creation of Aeroput in 1927. , Corfu, March 1916 made in Aeroput workshops in Zemun, 1935 The first technicians and mechanics started working as pioneers of this profession in 1927. Jat Airways was founded in 1947 as the successor of Aeroput. In 1963 a 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, leader of the company launched a strike that paralysed the national airline Jat Airways for a month. Jat technicians were unhappy with their working conditions and pay. 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. The Government of Serbia, which wholly owns Jat Airways, separated Jat Tehnika from the parent company in 2006 to end the dispute. Jat Tehnika received its JAR 145 certificate from the European Aviation Safety Agency, allowing the company to maintain all aircraft from the European Union, in 2005. The company obtained a certificate from the American Federal Aviation Administration to service airlines from the United States in 2007. In July 2019, the Government of Serbia announced auction of the company, with plans to sell its 99.4% share in company's ownership. On 28 November 2019, the Government of Serbia accepted the offer of Czech-Polish group "Avia Prime" to take over the company for 10.30 million euros.
