principal training aircraft. Performing its maiden flight on 4 November 1968, it became the first trainer aircraft in the world to be equipped with a turbofan powerplant. Quantity production of the L-39 Albatros proceeded in 1971; one year later, it was formally recognized by the majority of the Warsaw Pact countries as their preferred primary trainer. Accordingly, thousands of L39s would be produced for various military customers in Eastern Europe. Additionally, it was exported to a range of countries across the world both as a trainer and a light attack aircraft. Since the 1990s, it has also become popular among civilian operators. By the end of the century, in excess of 2,800 L-39s had served with over 30 air forces. Several derivatives of the L-39 Albatros were developed. During the 1980s, Aero Vodochody used it as the basis for the L-59 Super Albatros, an enlarged and updated model. Furthermore, the L-39 lineage would be extended to the L-139, a prototype L-39 fitted with a Western-sourced Garrett TFE731 engine. A combat-orientated development of the aircraft, designated as the L-159 ALCA, entered production in 1997 and has since been procured by a range of export customers. Production of the original L-39 came to an end during the mid-1990s, orders having declined substantially following the end of the

Development

In 1964, the Czechoslovak aircraft manufacturer

embarked on a new design project to meet the specified requirements for a "C-39" (C for ''cvičný'' – trainer), setting up a design team under the leadership of Jan Vlček. This aircraft was to serve as a replacement for the Aero L-29 Delfín, an early jet-powered trainer, as a principal training aircraft.Lake 2000, pp. 117–118. Vlcek envisioned the type, a twin-seat single-engine aircraft, being adopted as the primary trainer throughout the Warsaw Pact nations. On 4 November 1969, the L-39 (under the designation "Prototype X-02" – the second airframe to be built) conducted its maiden flight, for which it was piloted by Rudolf Duchoň, the factory's test pilot."Aero L-39 Albatros."
''Flight International'', 18 November 1978. p. 1872.
Serial production of the initial model of the L-39, designated ''L-39C'', commenced in 1971. During 1972, the L-39 Albatros was formally recognized by the majority of the countries comprising the Warsaw Pact as their preferred primary trainer, after which point, sizable orders from military customers throughout the bloc proceeded, many of which were from the

. In 1974, the first L-39 trainer entered service with the Czechoslovak Air Force. Several specialised variants of the base L-39 design were quickly introduced. In 1972, a purpose-built target tug variant, the L-39V, conducted its initial flight. During 1975, the first L-39ZO training/light combat model, which was equipped with four underwing

s as well as a strengthened wing and modified landing gear, performed its first flight. In 1977, the first L-39ZA light combat variant, which was fitted with a single Gryazev-Shipunov GSh-23 cannon mounted underneath the fuselage in addition to the four hardpoints and strengthening of the L-39ZO, made its maiden flight. According to aerospace publication Flight International, roughly 200 L-39s were being sold each year upon the jet trainer market during the late 1980s. According to the Stockholm International Peace Research Institute, in 1993, the total export orders gained for the L-39 represented 80 per cent of the value of all Czech military product export sales made for that year. During the 1990s, shortly following the

Sales of the L-39 declined during the 1990s. This downturn has been attributed to the loss of the captive Warsaw Pact trainer market, to which a substantial proportion of the total aircraft manufactured had been historically sold to; allegations about Czechoslovak banks being unable to finance the defense industry and inaction on the part of the Czechoslovak government; and concerns over the quality of manufacturing standards.Jeriorski, Andrzej
"Business Analysis: Dilemmas in Prague."
''Flight International'', 5 April 1994.
In 1996, production of the L-39 came to an end. Since the end of production, Aero Vodochody has developed several improved variants of the L-39 to take its place, and has continued extensive support and overhaul operations for existing L-39 customers. One of the replacements for the L-39 Albatros was the Aero L-159 Alca, a modernised version of the L-39. Originally, Aero Vodochody had intended to develop the L-159 in partnership with Elbit, but the Czech Ministry of Defense instead selected Rockwell Collins to partner on the program. The limited success of the L-159 led Aero to announce at the 2014 Farnborough Airshow that it was developing an upgraded version of the L-39, designated L-39NG, to compete with the

The first flight of the L-39NG was in December 2018, and final military type certification was granted by the Czech Military Aviation Authority in 2022. The first production L-39NG is expected to fly by the end of 2022.


Design

The L-39 Albatros was designed to be a cost-effective jet-powered trainer aircraft, which is also capable of performing ground attack missions. For operational flexibility, simplicity, and affordability, the majority of onboard systems have been simplified to avoid incurring high levels of maintenance, as well as to minimize damage caused by mishandling when flown by inexperienced air crew. It could be readily flown from austere airstrips such as frozen lakebeds, enabled through the rugged design of the landing gear and favourable low landing speeds. The aircraft's flying qualities are reportedly simple, which is made easier by way of a rapid throttle response, making it easier for students who had never previously flown a jet aircraft before to successfully control. As a training platform, the L-39 itself comprised part of a comprehensive system which also used flight simulators and mobile ground test equipment. The low-set, straight wing has a double-taper planform, 2½-deg dihedral from the roots, a relatively low aspect ratio, and 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. An automatic trimming system was present, the flaps and the trim system being connected in order to counteract the potentially large pitch changes that would otherwise be generated by vigorous movements of the flaps.Wilkinson 2005, p. 165. 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. The 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

A long, pointed nose leads back to the tandem cockpit, in which the student and instructor sit on Czech-built VS-1 ejection seats under individual canopies, which are opened manually and are hinged on the right. The rear seat, typically used by the instructor, is elevated slightly to readily enable observation and guidance of the student's actions in the forward position.Wilkinson 2005, p. 164. The design of the cockpit, panel layout and many of its fittings resemble or are identical in function to those of other commonly-used Soviet aircraft; for example, the procedure for deploying the ejection seat is exactly the same as for the Mikoyan MiG-29.Wilkinson 2005, p. 166.

A single turbofan engine, an Ivchenko AI-25TL (made in the Soviet Union) is positioned in the rear fuselage, fed through shoulder-mounted, semi-circular air intakes (fitted with splitter plates) just behind the cockpit and the tailpipe below the horizontal tailplane. The engine has a time between overhaul (TBO) of 1,000 flight hours; however, it is allegedly cheaper than the majority of turbine engines to overhaul.Wilkinson 2005, p. 169. Five rubber bag fuel tanks are located in the fuselage behind the cockpit. Several heavy radio units are typically installed in an aft avionics bay; these are often removed on civilian-operated aircraft and replaced with a 70-gallon fuel tank. Additional fuel tanks can be fitted in the rear cockpit position and externally underneath the wings; the tip-tanks can also be expanded for a greater fuel capacity. The aircraft is fitted with a hydraulically-actuated retractable nosewheel undercarriage which is designed to allow operation from grass airfields. The main landing gear legs retract inward into wing bays while the nose gear retracts forward. The basic L-39C trainer has provision for two underwing pylons for drop tanks or practice weapons, but these are not usually fitted. It can be armed with a pair of K-13 missiles to provide a basic

Operational history


Abkhazia

During the War in Abkhazia (1992–1993), Abkhaz separatist forces received several L-39s from Russia and Chechnya, which were used in combat against Georgian forces. On 10 January 1993, a Abkhaz L-39 was shot down by a Russian SA-11 Buk during a friendly-fire incident. The pilot, Oleg Chanba, who was commander of the Abkhaz separatist air force, was killed during the incident. On 1 April 1993, during the attack on civilian targets in

Iraq

Iraq became the first export customer for the L-39 Albatros. By mid 1970, the Iraqi Air Force had procured a considerable number of L-39 trainers, having transferred the bulk of their training activities onto the Czechoslovak aircraft. During the American-led invasion of Iraq in 2003, on 14 April 2003, a pair of United States Navy McDonnell Douglas F/A-18 Hornets attacked several L-29 and L-39 aircraft on the ground at an airfield near the city of Tikrit; these had been believed to have been modified to perform as delivery platforms for weapons.

, launching several strikes upon rebel-held positions. It has been claimed the L-39 was the first fixed-wing aircraft to be employed against the rebels. In February 2013, insurgents successfully captured a number of intact L-39s, along with their support equipment, after raiding and later taking over the Al-Jarrah airbase. In late 2013, reports emerged of claims by Islamist fighters that they had successfully flown two of the captured L-39s. In October 2014, the Syrian Government claimed that at least two rebel-held L-39s had been airworthy and had recently been destroyed by Syrian Air Force aircraft. According to Reuters, by 2014, the L-39 had allegedly become one of the favoured platforms of the Syrian Air Force for performing ground attack missions due to its slower speed and higher agility over other aircraft in its inventory.

Civilian use

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 warbird owners all over the world. It has been claimed that the L-39's desirability stems from the fact that it is "the only available second-generation jet trainer". This trend 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 being introduced at the Reno Air Races in 2002, though it has since been expanded to include other, similar aircraft. In September 2012, there were 255 L-39s registered with the U.S. Federal Aviation Administration and four registered with Transport Canada. Several display teams use the L-39 such as the Patriots Jet Team (6 L-39s), the

(7 L-39s) and the Black Diamond Jet Team (5 L-39s). There are also several L-39s that have been made available for private jet rides by various operators in Australia, Czech Republic, France, Germany, Spain and the USA. These L-39s are mostly in private hands, but some also belong to government agencies, such as those in Vyazma, Russia. In March 2018 there were five L-39s on the civilian register in New Zealand.
