The Aero L-39 Albatros is a high-performance jet trainer aircraft developed in Czechoslovakia to meet requirements for a "C-39" (C for cvičn - trainer) during the 1960s to replace the L-29 Delfxn. 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 engine Garrett TFE731). The design is still produced in an evolved state as the L-159 ALCA, while more than 2,800 L-39s still serve with over 30 air forces around the world. The Albatros - the most widely used jet trainer in the world - is versatile, seeing duty in light-attack missions as well as in basic and advanced pilot training.

Design and development

The L-39 (under the name Prototype X-02) first flew on 4 November 1969 and was piloted by Rudolf Duchoň, main factory's test pilot. Serial production began in 1971. The design is Czechoslovak (Czech) - the construction of Aero's chief designer Jan Vlček. The L-39 Albatros is a widely flown trainer/light attack aircraft similar in mission to the Italian MB339. Until now is in service with various former Soviet allies.

The low, slightly swept wing has a double-taper planform, 2-deg dihedral from the roots, a relatively low aspect ratio, and 26-gal US (100-liter) 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 9,259 lb (4,200 kg) are +8/-4 g.

A single turbofan engine, an Ivchenko AI-25TL (made in Soviet Union) is embedded in the fuselage and is fed through shoulder-mounted, semi-circular air intakes (fitted with splitter plates) just behind the cockpit; the engine exhausts below the tailplane. Five rubber bag fuel tanks are located in the fuselage behind the cockpit. The main, trailing-arm landing gear legs retract inward into wing bays; the nose gear retracts forward.

A long, pointed nose made of aluminum leads back to the tandem cockpit, in which the student and instructor sit under individual canopies that are hinged on the right. The rear (instructor's) seat is raised slightly; both ejection seats are made by Aero.

The basic trainer is not armed, but has two underwing pylons for drop tanks and practice weapons. Light-attack variants have four underwing hardpoints for ground attack stores; the ZA also has an underfuselage gun pod.

This model is no longer in production and is replaced by the L-159.

Abkhazia

In the spring of 2008, a number of Georgian drones were shot down by Abkhaz separatist or Russian forces. In the first of these occasions, on April 20, 2008. Another was shot down by a Russian MiG-29 over Abkhazia region. The Abkhazian separatist forces claimed that one of its missile-equipped L-39 had downed a Georgian Hermes 450 unmanned reconnaissance drone. [1]

Popular warbird

While newer versions are now replacing older L-39s in service, thousands remain in active service as trainers, and many are finding new homes with private owners all over the world. This is particularly evident in the United States, where their $200,000-$300,000 price puts them in range of moderately wealthy pilots looking for a fast, agile personal jet. Their popularity led to a purely L-39 Jet class at the Reno Air Races (though it has since been expanded to include other, similar aircraft). As of mid-March 2006, there are 257 L-39s in the US Federal Aviation register. The first legally registered L-39 private aircraft was successfully flown on a cross country ferry flight in the US on December 9, 1992 with Pilot D. McCue and observer J. Yurick .

Several display teams use the L-39 such as The Patriots Jet Team (4 L-39s) and the Breitling Jet Team (7 L-39s).

There are also several L-39 available for private jet rides: In the United States: in Florida, New York and California, in Czech Republic, Germany, Switzerland and Russia. Those L-39 jets are partly in private hands. But they can also belong to training facilities of the Ministry of Defense, this is the case in Vyazma, Russia.

In popular culture

A L-39 was used in the James Bond film, Tomorrow Never Dies, where the James Bond character steals the aircraft. The 2005 film Lord of War features a scene in which a L-39 intercepts an An-12 cargo plane.

It also features prominently in ArmA II Operation: Arrowhead as a fighter for the Takistani Airforce.
