How about trying to find out how much damage the plane gets while operating off different types of strips.
See if they have problems with skin damage etc. Would a deflector on the gear stop damage to the flaps.
That's a great idea, I will try to search about that.
The thing is though, information regarding this plane in terms of specific aircraft structure and materials used seems to be so limited. I've tried a dozen different google searches to find out the materials used during manufacture and so far the only thing I got is that there is some use of "fire-resistant" materials... grrrr....
Don't think the university library will have a book called the "Let 410" either.
There were a few interesting topics on pprune about a comparison of the Let 410 to the DHC-6 which was very useful but mostly all to do with performance, very little in terms of structure and design.
