LASTA-95 / Swallow 95

Lasta 95 is a single-engine, low-winged metal aircraft, with two pilot seats, one in front of the other. It is able to take off and land on concrete and grass landing strips LASTA-95 aircraft is designed for selection, initial and basic training of pilots, it offers low landing and takeoff speeds and pilot-friendly handling, forgiving potential errors by inexperienced pilots. The aircraft was designed in compliance with Federal Aviation Regulations (F.A.R. Part 23: Airworthiness Standards). The BASIC VERSION OF THE AIRCRAFT is built against the requirements for aerobatic category loads of (nz_max = 6.0, nz_min = -3). The ARMED VERSION OF THE AIRCRAFT is built against the requirements for utility category with loads of (nz_ max = 4.4, nz_ min = -1.8).

Flight tests of the Lasta 95 training plane, the first domestically designed aircraft produced at the Utva factory of Pancevo since the breakup of the Socialist Federal Republic of Yugoslavia, were begun successfully at the Batajnica military airport in Febrary 2009. The launch of serial production at the plant is expected after all tests are completed. The Iraqi military has ordered 20 Lastas [some reports state that Serbia has sold 36 Lasta-95 training aircraft to the Iraqi Air Force], while 16 aircraft are to be produced for the Serbian army to replace the Utva 75 plane in pilot training.

Defense Minister Dragan Sutanovac stated at Batajnica air port, after attending the first test flight of Lasta 95 training aircraft, that this was an excellent air craft which would serve for the training of home and foreign soldiers from all over the world. The promotional flight was attended by the Chief of SAF GS LTG Miloje Miletic with his coworkers and the top officials from the defense system as well as numerous reporters. The plane was operated by Lt. Col. Salko Hadzic from the Flight Testing Center of the Technical Testing Center.

Only 4 or 5 European countries produce this type of planes, and only ten in the whole world make these planes.. So this makes us the country with wings of it own, its own aviation industry we take great pride in. this means introducing a new plane into the training process, which means 6 times less money spent on the training of every pilot per hour. For example, an hour on Galeb G4 costs 2000 EUR, while on Lasta it costs only 300, said Minister adding that this was another way of the Ministrys contribution to the savings in the budget.

The attention of the domestic public was drawn to Lasta 95 when it was first represented at the arms fair Partner 2007. In July last year this became the main topic when Yugoimport SDPR first signed the contract with the Iraqi Ministry of Defense on arms export. This contract envisions that 20 propeller planes Laste-95 for training be exported into Iraq. The manufacturer of the final stages of the air craft and the main manufacturer is DOO Utva, Aviation Industry Pancevo. The Utva Aircraft Factory was established in 1937 in Pancevo, outside of Belgrade, and was heavily damaged in NATO air strikes on Yugoslavia in 1999.

With its specifications and updated avionics, the aircraft will ensure full pilot training for all elements of airplane application including:

  • basic flying,
  • figure flying,
  • navigation flying,
  • basic elements of night flying,
  • category II instrumental flight,
  • basic elements of gunning, rocketing and bombing (GRB)
  • Light close air support of counterinsurgency operations and area patrol / light attack missions

Lasta-95 landing gear is equipped with mechanical emergency system for landing gear extension (in the event of failure of hydraulics). This mechanical system ensures positive extending and locking in extended position of all three struts, at horizontal aircraft speeds up to 180 km/h. Minimizing of structural mass was achieved by application of advanced stress calculation methods including numerical simulations to meet strength and rigidity requirements. Aircraft fuselage structural stress was verified by testing, confirming the adopted concept and approach for de-dimensioning of structural components.
