There is a few reasons why the LET 410 is at present in the top 10 list of most popular turbo-props around!!!!!
1) It's Reliable ( It never goes Tech)!!!!
2) Its Cheap to run and operators love it!!!!!
3) Its easy to fly and the pilots who fly it Love it!!!! (Me speaking from 2300Hrs on Type)!!!!!!!
4) THERE ARE NO PROBLEMS OPERATING THE TYPE IN EUROPE!!!!! I KNOW THIS AS I FLY IT IN EUROPE!!!!! GO WITH THE MIGHTY LET!!!!!!
