Grumman G-73 Mallard

The Grumman G -73 Mallard ( Mallard ) is a twin-engine amphibious aircraft of the U.S. American manufacturer Grumman.

History

The pattern is based on the smaller patterns Goose and Widgeon and launched on April 30, 1946 for its first flight. The shoulder wing has a nose wheel retractable landing gear. The engines are above for protection against splash water and mounted in front of the wing. The hull was designed in two stages; at the wing tips auxiliary tanks can be attached. In the years 1946-1951 a total of 59 copies were made ​​, most of which as business travel and private aircraft were used with appropriate salon equipment. Few served as a transport aircraft, such as at Chalk 's Ocean Airways.

A number of these machines is still in use today. 2001 there were still 32 copies recorded in the United States. The radial engines were often replaced with these machines since the early 1970s by Pratt & Whitney Canada PT -6 -34 turboprop engines with 551 kW of power and modern Hartzell propellers. The initial conversions were carried out by the company Frakes Aviation, the first machine in 1969 launched its maiden flight and was admitted in October 1970. These machines are as Turbo Mallard G- 73T or referred. The seating was changed so that 17 passengers can be accommodated. Largest operator with four aircraft of this type was the Chalk 's Ocean Airways, until she lost her pilot's license on 30 September 2007.

Accidents

A Mallard of Chalk 's Ocean Airways crashed due to inadequate maintenance and lack of supervision on the part of the FAA by the demolition of a wing on the way to the Bahamas near Miami Beach on December 20, 2005.
