The 76 airframe is manufactured in the Republic of Czechoslovakia, shrink wrapped and air freighted to Stratford for powerplant, drivetrain installation and completed in Pennsylvania.
The Arriel is actually a Polish design… well ok, it was designed by the company (Turbomeca) that was established by a Polish emigrant, Joseph Szydlowski. Look for his name on various dataplates on the Arriel.
