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:
