Hello Hasan!
Dear Sir,

I just have seen your post on the Mi-17 forum http://www.aviastar.org/helicopters_eng/mi-17.php
Please make a note that we supply all spares for Mi-8/17 type helics.

Should you need some - welcome! We've got pretty massive warehouse in Moscow and are well connected with OEMs in Russia/CIS. Also we work with MROs - order component repairs and supply the plants with spares.

Looking forward to hear from you.
