The L-39 is a true legend among jet trainers. Manufactured in numbers that will hardly ever be beaten by any other jet training type, its elegant shape and reliable performance is something thousands of pilots will never forget.

The L-39 and its successors L-59, L-139 and L-159 became the most successful jet training family worldwide ever.

  • Over 3,000 aircraft in various configurations were manufactured up to now with an expected further increase upon the launch of the L-39NG production.
  • Over 5,000,000 flight hours total log of the fleet with dozens of thousands of pilots trained on AERO jets. Can you imagine that several generations of pilots - both in the military and the civilian sector - have started their jet career on the L-39 family? Our jets were used not only for the preparation of pilots or condition flying, but also for regular air force tasks and even astronaut training.
  • 60 operators in total on all continents means the type is recognized for its high versatility and adaptability. AERO jets successfully operate in NATO countries as well as in countries equipped with Russian jets. For instance, there are dedicated L-39 variants equipped with Western or Eastern style of cockpit capable of carrying Western and Eastern ammunition.
  • The ultimate versatility of the jets can be well shown on the fact that AERO trainers were used literally for any mission an air force may fulfil. Starting with all training stages from elementary to lead in fighter training, through air patrolling, close air support, surveillance, reconnaissance, test and calibration flights, up to professional aerobatic formation flying.
  • The ultimate versatility of the design is visible from the fact, that basically the same aerodynamic concept of L-39 was powered by several different engines. The L-39 with the AI-25TL engine (16.87 kN of thrust) was followed by models such as the L-59 (DV-2 engine with 21.57 kN of thrust), the L-139 (TFE731 with 18.15 kN of thrust), the L-159 (F124GA-100 with 28.2 kN of thrust) and finally the L-39NG with its outstanding FJ44-4M engine (16.89 kN of thrust).
  • The civilian variant operated by 15 countries proves how adaptable the type is. The L-39 family and its successors are widely used not only for hobby flights, but also for commercial organisations supporting air forces. The L-39 and L-159 soon became the symbol of commercial aggressors flying training missions in support of the top air forces, such as the US Air Force, US Navy, French Air Force, Royal Netherlands Air Force and many others.   
  • Operation by 15 jet demonstration teams is an excellent proof of how good the handling characteristics of the L-39 family are. Dozens of millions of spectators were admiring the beauty of wingtip to wingtip formation on the L-39 since the first team was established back in 1987. Since that time, the L-39 became the most popular jet for aerobatics worldwide, being operated by such excellent teams as the Breitling Jet Team, Black Diamond Jet Team, Hoppers Jet Team, Patriots Jet Team and many others.
  • Operated in all climatic conditions, reaching from arctic over desert to humid areas, there are literally no conditions AERO aircraft have not yet been deployed in. There is no better example of the L-39 family’s robustness than the fact, that basically the same configuration of the jet was flying in 40°C in humid areas as well as in -40°C in freezing artic environment. And in all those conditions, the L-39 family always accomplished its mission.  
  • Maximum annual production rate of 250 aircraft. Yes, the number is correct. In the history of the aircraft, there were years when a new aircraft appeared on the flight line. Ferry flights to customers consisted of a formation of flights of dozens of jets at once. At the same time, three final assembly lines were active to satisfy the customers´ demands.
