Tinadar Aviation has temporarily suspended its operating licence in December 2024 to reduce costs during the off-season, with plans to reactivate it in May 2025, CEO Arnold Mingin confirmed to ch-aviation. The company is also offering its two Citation Jets and Air Operator's Certificate (AOC) for sale, while a Citation Jet 3 is now operated by Flyus.

The two Citation Jets are YU-BUZ (msn 525-0118) and YU-SAI (msn 525-0115), both manufactured in 2009. YU-SAI was last active on September 9, 2024, under the company's 'NAD' code, flying between Kraków John Paul II International and Ljubljana. YU-BUZ last operated using the 'NAD' code on November 18, flying from Podgorica to Ljubljana before conducting a test flight the same day. Since then, YU-BUZ’s flights have been performed using its registration as the callsign.

Meanwhile, a 17.2-year-old Citation Jet 3, YU-BTN (msn 525B-0193), part of Tinadar Aviation's fleet since August 2024, is now operated by Flyus, which recently obtained an operating licence. Flyus also operates a second Citation Jet 3.

At the same time the company temporarily suspended its operating licence, Mingin announced on LinkedIn that Tinadar Aviation's two Citation Jets and its AOC were for sale. "The offer to sell is out, but we will sell only if the price is right. We view the Serbian AOC as a valuable asset", Mingin told ch-aviation.

Tinadar Aviation is the parent company of Slovenia’s Alar Aviation, which operates a single Citation S/II, parked at Ljubljana since November 2024.

In 2024, the Serbian Civil Aviation Directorate suspended the Air Operator's Certificates (AOCs) of three operators. Currently, four private jet companies, Flyus, MPC Air, Prince Aviation, and Skybridge International, hold active AOCs and operating licences in Serbia.
