Inside the L-39
The engineering behind the success
One of the secrets of the L-39’s success is the quality and standard of engineering built into the airframe. Here we present examples of both military and civil versions of the trainer in detail and in close up.
The essential quality of the L-39 has enabled it to remain in service for over three decades, a proud record of service extended still further through overhauls and life extension programmes. As can be clearly seen, access to the major systems and structural elements of the aircraft is greatly facilitated by the large number of hatches and panels built into the airframe, making the L-39 popular with engineers as well as aircrew. We would like to offer our thanks to Lieutenant Colonel David Kudrna, the deputy wing commander at the Czech Air Force base at áslav, for his permission to photograph two of the 213th Tactical Squadron’s L-39ZAS in detail while they were undergoing maintenance, and of course to the engineering staff at the base who allowed us to interrupt their work with such good humour!
