L-39C
basic training aircraft
An aircraft for comprehensive military air force pilot training. In serial production since 1971. More than 250 of this version of the aircraft were produced.
Training equipment:
- Two hard points with a load capacity of 125 kg for training
- Excellent view from the cabin (the raised rear cabin gives a good instructor view)
- Control priority, and even full pilotage from the rear cabin for the instructor
- VS1-BRI ejection seats (at the time of the development of the L-39, there were only four countries in the world capable of the development and serial production of ejection seats for jet aircraft)
The reliability of the L-39’s rescue system was also verified in practice by several successful ejections by the crew.
L-39ZO
trainer and light fighter jet
On the basis of customer requests, the L-39C version was improved to make it more effective for combat pilot training.
Mission completion equipment:
- Four hard points
- The inner hard points are designed for a load capacity of 500 kg, and the outer for 250kg
- Reinforced wing with higher load capacity
- Reinforced landing gear
L-39ZA
light fighter jet
Created for the fulfilment of a wide range of air-to-air and air-to-ground missions, and improving pilots’ weapons training.
Additionally, compared to the L-39ZO version, it has:
- The option of using homing missiles on the outer hard points
- Cannon armament structure
- The option of using cannon, missile, and bomb armaments
- The weaponry enables the targeted firing of unguided missiles at ground targets during descending flight, launching of practice homing missiles during air combat with the option of strike control, targeted bombing, etc. It is also possible to aim at targets and photo-shoot at air and ground targets with a gun camera.
Program
L-39
Aero offers L-39 users a wide range of short-, medium-, and long-term solutions.
Aero offers a comprehensive maintenance programme for the L-39, which enables it to fly for decades to come.
Overhauls
Maintenance Repair & Overhaul
An overhaul literally gives an aircraft a “new lease of life”. We use unique know-how, documentation, and overhaul methods to ensure safe and reliable future operation.
Overhauled aircraft fulfil the same requirements as completely new aircraft coming off the production line, and have the full Aero guarantee.
Service life extension programme
Service life consumption and extension programmes
The service life of the L-39 is limited by cumulative fatigue, which is determined primarily by the amount and frequency of vertical load during operation.
If the aircraft is operated within the recommended design spectra, the aircraft’s actual service life in terms of flight hours exactly corresponds to the entries in the log book, and can reach 3,000–4,500 flight hours (depending on the version).
Remotorisation
For L-39 operators that want to increase their aircraft’s performance and availability, Aero offers the option of remotorising existing aircraft with new Williams International FJ44-4M engines with an output of 16.87 kN.
Logistics Support
We provide full after-sales support (spare parts, services, training, consulting, etc.)
o shorten delivery times and increase flexibility, Aero recommends that its customers take advantage of the FOSS (follow-on support service) contract.
In order to ensure the airworthiness of the L-39, despite the increasing age and number of hours flown, new maintenance and overhaul methods are used, including:
