Its Piaggio, and just try to spell Partenavia. Thanks for the info, its down in my acft designator as an p-136 not as an Avanti as one of the passengers told me. The avanti is down as a light 2 engine turboprop retractable gear. the p-136 is the piston twin amphib. Sheesh , I'l have to stop listening to those old retired flyers and airfield foremen.
