1st of all helicopter dont have massive G forces on them like airplanes so there fuselage wont get tired even if they fly for like 30 years beside iran helicopter industry is best in middle east 2nd iran have big number of Bell-214s with build only for iran and it's been called Bell-214 THE ESFEHAN ( one f the cities in iran ) and they are still in line of production in Esfehan !
