In­side the L-39

The en­gi­neer­ing be­hind the suc­cess

Aviation Classics - - CONTENTS - Words: Tim Call­away

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!
