ATF-Aviation (Bratislava) has retired its sole executive jet, a Citation Mustang, according to ch-aviation research. The aircraft, OM-FTS (msn 510-0281), is now operated by KG-Aviation, a Slovak entity that does not hold an Air Operator's Certificate (AOC).

The 14.6-year-old Citation Mustang had been part of ATF-Aviation’s fleet since 2021, serving as the only corporate jet following the retirement of a Citation Jet 1 in 2022. The aircraft changed operators between September and October 2024, although it remains based out of Vienna.

The jet is now operated by KG-Aviation, a company established in 2018 and managed by Austrian citizen Manfred Brodmann since April 2019. Brodmann was the founder of ATF-Aviation in July 2017 and co-owned the company from December 2017 until January 2023. At that time, he divested his share in ATF-Aviation and invested in KG-Aviation.

Brodmann had also owned Berlin Jets, another Slovak business jet operator, between June 2019 and its liquidation in August 2023.

ATF-Aviation's website is currently inactive and the operator could not be reached for comment. However, its certificate remains valid for the domestic and international non-scheduled air transport of passengers. KG-Aviation’s registered business activities include property rental, goods trading, and other services, with no mention of air transport operations.
