GRUMMAN MALLARD “G73″€

The Mallard was Grumman's entry into the civilian/commercial use amphibian category. Based on the smaller Goose and Widgeon designs, the larger G73 featured tricycle landing gear. Only 59 Mallards were ever built, but some saw a new life as a turboprop with Pratt & Whitney PT6A out front. A supplemental type certificate was issued for the kerosene burning versions in 1960, but even the performance boost delivered by the more powerful engines was not enough to keep the Mallards in service.
