what is it?

The Grumman G-73 Mallard is a medium, twin-engined amphibious aircraft. Many have been modified by replacing the original Pratt & Whitney Wasp H radial engines with modern turboprop engines. Manufactured from 1946 to 1951, production ended when Grumman's larger SA-16 Albatross was introduced.
