The Aero L-39 Albatros is a high-performance jet trainer aircraft developed in Czechoslovakia to meet requirements for a "C-39" (C for cvičný – trainer) during the 1960s to replace the L-29 Delfín. It was the first of the second-generation jet trainers, and the first turbofan-powered trainer produced, and was later updated as the L-59 Super Albatros and as the L-139 (prototype L-39 with Garrett TFE731 engine). A further development of the design, the L-159 ALCA, began production in 1997. To date, more than 2, 800 L-39s have served with over 30 air forces around the world. The Albatros is the most widely used jet trainer in the world; in addition to performing basic and advanced pilot training, it has also flown combat missions in a light-attack role. Atypically, it has never received a NATO reporting name. The L-39 (under the name "Prototype X-02" – the second airframe built) first flew on 4 November 1969 and was piloted by Rudolf Duchoň, the factory's test pilot. Serial production began in 1971. The design is Czechoslovak (Czech) – the construction of Aero's chief designer Jan Vlček. The low, slightly swept wing has a double-taper planform, 2½-deg dihedral from the roots, a relatively low aspect ratio, and 100 liter (26½ USgal) fuel tanks permanently attached to the wingtips .The trailing edge has double-slotted trailing edge flaps inboard of mass-balanced ailerons; the flaps are separated from the ailerons by small wing fences. The tall, swept vertical tail has an inset rudder. Variable-incidence horizontal stabilizers with inset elevators are mounted at the base of the rudder and over the exhaust nozzle. Side-by-side airbrakes are located under the fuselage ahead of the wing's leading edge. Flaps, landing gear, wheel brakes and air brakes are powered by a hydraulic system. Controls are pushrod-actuated and have electrically powered servo tabs on the ailerons and rudder. Operational g-force limits at 4, 200 kg (9, 260 lb) are +8/-4 g. This is a civilian owned L39
