Fabrica Aeroplana I Hydroplana Zmaj
Fabrica Aeroplana I Hydroplana Zmaj founded in 1927 by Jovan Petrovic to produce under license the Hanriot H-41, Gourdou-Leseurre B-3 and Dewoitine D-27 fighters. Indigenous designs included a Wright-engined observation aircraft, an observation seaplane, and the two-seat Fizir AF-2 Amphibian.
Four out of five Yugoslav aircraft plants were in close proximity to each other, built in and around Belgrade: Ikarus, Rogožarski, Zmaj and Utva. The fifth one was DFA (Državna Fabrika Aviona - State Aircraft Factory) which was located in Kraljevo.
