Super Privrednik-350

The UTVA-65 agricultural aircraft first flew in 1965.

The Privrednik-GO initial version was powered by a 295 hp Lycoming GO-480-G1A6 engine with a constant speed propeller.

The Privrednik-IO is the export version of the -GO with a softer landing gear. Power was a Lycoming IO-540-K1A5 with fixed pitch or constant speed propeller.

The Super Privrednik-350 is a more powerful version.

UTVA C-3 Trojka / BC-3 / Ikarus 251 / Cijan C-3 Trojka

TerryLeave a comment

The Utva C-3 Trojka (Trey) was a light aircraft built in Yugoslavia shortly after World War II as a result of a government competition to develop a new, domestically built aircraft with which to equip the country’s flying clubs. The winning design was submitted by Boris Cijan and Dragoslav Petkovic and the prototype was built by Ikarus as the Ikarus 251.

The prototype first flew towards the end of 1946. Series production took place at Utva as the C-3 and the first production Trojka were delivered in 1949. It was a conventional, low-wing cantilever monoplane with fixed tailwheel undercarriage. The pilot and instructor sat side by side under an expansive canopy.

The type remained in production until the mid-1950s. Later examples were powered by a 105 hp Walter Minor 4-III engine from 1953. About eighty were built.

The type was operated by the Yugoslav Air Force.

UTVA, Fabrica Aviona

Jugoslavia / Serbia

Utva Aircraft Industry (commonly known as UTVA) is a manufacturer of general aviation aircraft, located in Pančevo, Serbia. Utva in Serbian is the Ruddy Shelduck.

Utva was founded on 5 June 1937 in Zemun (a small town in former Austrohungarian empire), and produced simple gliders. In 1939 Utva began manufacturing light piston engine aircraft.

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. The plant was relocated to Pančevo (a town a few kilometers away from Belgrade, in Vojvodina autonomous province) in 1940. Until the April war, it mainly produced light gliders but it also produced 148 Bucker Jungmann Bu-131D-2 training planes and one acrobatic Bucker Jungmaister Bu-133. The plant escaped the devastation of the other aircraft plants (Ikarus, Rogožarski and Zmaj) and began producing it’s prewar gliders Čavka (Daw) and Ždral (Crane – the bird) and school airplanes Trojka (Three) and Aero 3. Utva also built a lot of Ikarus designs, notably the 212 and 213 models.

Utva produced light utility aircraft, including the Utva 56 four-seater, first flown in 1956, and thereafter developed through a number of U60 air-taxi/tourer/freight/agricultural/ ambulance and floatplane versions. The Utva 65 was originally an agricultural aircraft, developed as the U66 to serve various utility roles and including the armed U66V version. The Utva 75 two-seat trainer/glider-tug/agricultural aircraft entered production in late 1970s. Lasta 1 tandem two-seat piston-engined trainer first flew September 1985 but was superseded before production by the design of the refined Lasta 2. Development started of Utva 95 agricultural aircraft, probably based on Utva 75. Formerly fabricated components for the IAR-93/J-22 Orao and Super Galeb programmes, and produced items for various Boeing airliners.

During the NATO bombing of Yugoslavia in 1999, the factory was bombed several times and severely damaged.

The factory was heavily bombarded in 1999 and certain parts of it were still off limits due to the unexploded ordnance in 2012. All five original lasta 95 prototypes were destroyed in the factory and the only existing Supergaleb G4MD prototype was lightly damaged. 2012 was back to the basics for Utva. The plant produced Lasta 95 basic trainer and was developing Kobac (sparrow hawk) light COIN aircraft (first flight is expected in 2013).

In 2011, Utva Pančevo was a public company with the headquaters in Pančevo, Serbia, serving 301 employees.

Aeronautica Umbra S.A

Italy
The Aeronautica Umbra S.A. of Foligno was established in 1935 by Muzio Macchi, and was primarily concerned throughout the war years with sub-contract work for other aircraft manufacturers. Umbra built Savoia-Marchetti S.M.79 torpedo-bombers under licence. However, Aeronautica Umbra’s design office, which was responsible for the unsuccessful T.18 single-seat fighter of 1938, designed by Dr. Ing. F. Trojani, did undertake some original work, and a heavy fighter of advanced and unorthodox design, the M.B.902 designed by Ing. Bellomo, was actually built, although flight testing had not commenced when the prototype was destroyed.

The construction of the M.B.902 was begun in 1942, and this single-seat fighter was unusual in being powered by a pair or 1,250 h.p. Daimler-Benz DB 605 liquid-cooled engines buried in the fuselage and driving twin contra-props mounted outboard on the wings via extension shafts. Featuring a retractable nose wheel undercarriage and carrying an armament of four 20-mm. and two 12.7-mm. guns, the M.B.902 had an estimated maximum speed or 429 m.p.h., and a maximum range of 1,056 miles.

Postwar production comprised aircraft and systems components until work was begun, in 1968, on the AUM-903 three-engined STOL light transport project. Production concentrated on licence manufacture of the Scheibe SF-25B Motorfalke motor glider for the Italian and North African markets.
