History: A Proud Tradition

The original Grumman Mallard was the first aircraft certified by the FAA in the transport category. It was designed for regional airline operations with two pilots and ten passengers and targeted harbor-based, city-to-city hops on the eastern seaboard. Mallards were flown by small carriers (Tahiti-Hawaii Airlines and Pacific Western Airlines) and corporate operators, including Aga Khan.

Beginning in 1970, the late J. Fred Frakes began engine conversions from early radial piston power to Pratt & Whitney turbine engines. From 1970 to 1984, Frakes converted 8 Mallards while in Texas. He later purchased the type certificate for the Mallard and incorporated the turbine STC into the type certification. 

The all-new Turbine Mallard heralds back to the original Grumman design, only with 21st-century upgrades including all-new Pratt & Whitney Canada PT6 engines, Rockwell Collins avionics and a host of other details and design features.

The Turbine Mallard prototype first flew and the first production aircraft entered service in 1946.

The Turbine Mallard is fully equipped with the latest Pratt & Whitney Canada PT6A-34 engines, Collins avionics, and exacting attention to detail from tip to tail. It’s versatile and functional, all with turbine-engine safety.
