Modifications[change | change source]

G-21G Turbo Goose modified by McKinnon with PT6A turboprops

There were a number of modifications of the Goose, but the most numerous were those by McKinnon Enterprises, who made three different conversions.[source?] The first involved replacing the Goose's engines with four Lycoming GSO-480 piston engines. The second, named "Turboprop Goose" involved replacing the engines with two Pratt & Whitney Canada PT6A turboprops. The third and final variant was the "Turbo-Goose," which was based on the "Turboprop Goose," but with larger windows and retractable floats on the wings.

New production[change | change source]

In November 2007, Antilles Seaplanes of Gibsonville, North Carolina announced it was restarting production of the Goose.[1] PWC PT6A-34 turboprops will replace the original Pratt & Whitney piston engines,[1] and the airframe and systems will be updated, increasing the seating capacity from eight to 10 places; the aircraft will be known as the Antilles Super Goose. The first example is now being assembled.[1]

Operational history[change | change source]

Goose of the Royal Air Force
Grumman G.21 of Alaska Island Air in 1989

Envisioned as corporate or private "flying yachts" for Manhattan millionaires, initial production models normally carried two to three passengers and had a bar and small toilet installed. As well as being marketed to small air carriers, the G-21 was also promoted as a military transport. In 1938, the US Army Air Force purchased the type as the OA-9 (later, in the war years, examples impressed from civilian ownership were designated the OA-13A). The most numerous of the military versions were the United States Navy variants, designated the JRF.

The amphibian was soon adopted by the Coast Guard and, during World War II, it also served with the RCAF in the transport, reconnaissance, rescue and training roles. The G.21 was used for air-sea rescue duties by the Royal Air Force (RAF). The RAF, in a common naming convention with all of its aircraft, designated the type as "Goose."

On returning to civilian service, after the war, the Goose found continued commercial use in locations from the wilderness of Alaska to the sunny climes of Catalina.

A total of 345 were built, with about 60 still airworthy today, most being in private ownership, some of them operating in modified forms.[2]

Notable appearances in media[change | change source]

The Grumman Goose has been featured in films and television. A U.S. Navy JRF-1 Goose in early World War II paint scheme appears in full color closeup water-taxiing and climbing a ramp in the 1943 submarine film Crash Dive. A Grumman Goose is piloted by Rae Dawn Chong's character, Cindy (an off-duty flight attendant), throughout the Commando (1985) motion picture starring Arnold Schwarzenegger. A Goose named Cutter's Goose is prominent on the 1980s TV series Tales of the Gold Monkey starring Stephen Collins, inspired by the movie Only Angels Have Wings.

In Jimmy Buffett's first novel, Where is Joe Merchant?, protagonist Frank Bama owned and operated a rebuilt Grumman Goose dubbed the Hemisphere Dancer. (The actual Hemisphere Dancer is a Grumman Albatross that belongs to Buffett and is now the centerpiece for his Margaritaville Cafe restaurant in Orlando, Florida.)[source?]
