Grumman G-21 Goose

January 10, 2023

The Grumman G-21 Goose is an amphibious flying boat designed by Grumman to serve as an eight-seat "commuter" aircraft for businessmen in the Long Island area. The Goose was Grumman's first monoplane to fly, its first twin-engined aircraft, and its first aircraft to enter commercial airline service. During World War II, the Goose became an effective transport for the US military (including the United States Coast Guard), as well as serving with many other air forces. During hostilities, the Goose took on an increasing number of combat and training roles.

Design and development

In 1936, a group of wealthy residents of Long Island, including E. Roland Harriman, approached Grumman and commissioned an aircraft that they could use to fly to New York City.[1] In response, the Grumman Model G-21 was designed as a light amphibious transport. Grumman produced a high-wing monoplane of almost all-metal construction—the trailing half of the main wing and all of the flight control surfaces except for the flaps were fabric-covered. It was powered by two 450 horsepower (340 kW) Pratt & Whitney R-985 Wasp Junior nine-cylinder, air-cooled, radial engines mounted on the leading edges of the wings. The deep fuselage served also as a hull and was equipped with hand-cranked retractable landing gear. First flight of the prototype took place on May 29, 1937.[2]

The fuselage also proved versatile, as it provided generous interior space that allowed fitting for either a transport or luxury airliner role. Having an amphibious configuration also allowed the G-21 to go just about anywhere, and plans were made to market it as an amphibian airliner.[3]

Modifications

A number of modifications were made for the Goose, but the most numerous are those by McKinnon Enterprises of Sandy, Oregon, which holds 21 supplemental type certificates (STCs) for modifying G-21-series aircraft and which also manufactured four different conversions that were recertified under a separate FAA type certificate as brand-new "McKinnon" airplanes.[4] The first was the McKinnon model G-21C which involved replacing the original R-985 radial engines with four Lycoming GSO-480-B2D6 piston engines. It was approved under TC 4A24 on November 7, 1958, and two examples were converted in 1958–1959.

New production

In November 2007, Antilles Seaplanes of Gibsonville, North Carolina, announced it was restarting production of the turbine-powered McKinnon G-21G Turbo Goose variant, now identified as the Antilles G-21G Super Goose.[1] Pratt & Whitney Canada PT6A-34 turboprops flat-rated to 680 shp (510 kW) would have replaced the original PT6A-27 engines,[1] and the airframe systems and especially the avionics (aviation electronics – i.e. radios and navigation systems) would have been updated with state-of-the-art "glass panel" instrumentation and cockpit displays. However, as of 2009, Antilles Seaplanes' manufacturing center has been foreclosed and sold at auction. The fate of new Goose production is currently unknown.[5]

Operational history

 
Alaska Island Air G-21A 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. In addition to being marketed to small air carriers, the G-21 was also promoted as a military transport. In 1938, the U.S. Army Air Corps 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 amphibious aircraft was also adopted by the Coast Guard and, during World War II, served with the Royal Canadian Air Force in the transport, reconnaissance, rescue, and training roles. The G-21 was used for air-sea rescue duties by the Fleet Air Arm, who assigned the name Goose. A single aircraft was used briefly by No. 1 Air Ambulance Unit, Royal Australian Air Force in the Mediterranean.[21]

After the war, the Goose found continued commercial use in locations from Alaska to Catalina and the Caribbean.

A total of 345 were built, with about 30 known to still be airworthy today[when?] (although around 60 are still on various civil registries, many of them are known to have crashed or been otherwise destroyed), most being in private ownership, some of them operating in modified forms.[6]

Variants

G-21
The original production version, these were powered by two 450 hp (340 kW) Pratt & Whitney Wasp Junior SB engines, at 7,500 lb (3,400 kg) gross weight, with six passengers, and 12 were built, all converted to G-21A standards.[7]
G-21A
Increased gross weight (8,000 lb (3,600 kg)), 30 built.[7]
G-21B
Export coastal patrol flying boat armed with .30 in (7.62 mm) machine gun in bow and dorsal hatches and two 100 lb (45 kg) bombs underwing, 12 built for Portuguese Naval Aviation.[7]
G-21C
Conversion by McKinnon Enterprises, these were re-engined with four 340 hp (250 kW) Lycoming GSO-480-B2D6 air-cooled, geared, and supercharged flat-six engines and fitted with retractable wingtip floats, a fiberglass radar nose, a one-piece wraparound windshield, and enlarged cabin windows; gross weight increased to 12,499 lb (5,669 kg) as result of internal structural reinforcements. Two were converted as piston-powered models G-21C in 1958–1959, and two other airframes subsequently were converted in 1968, but with two 550 shp (410 kW) Pratt & Whitney Canada PT6A-20 turboprops per STC SA1320WE as G-21C Hybrids. Two G-21C Hybrids were identical to the later 10,500 lb (4,800 kg) model G-21E, but they were never certified as such.[8]
G-21D
One G-21C was further converted by McKinnon with an extended nose marked by two extra windows on each side and accommodating another four passengers. Recertified as G-21D in 1960. In 1966, it was re-engined with two 550 shp (410 kW) PT6A-20 turboprops and fitted with revised Alvarez-Calderon electric flaps in accordance with STC SA1320WE, retaining the G-21D designation, but subsequently identified as the McKinnon "Turboprop Goose".[9]
G-21E
A fully certified new model, it was based on a simplified turbine conversion of the McKinnon G-21C, with 550 shp (410 kW) PT6A-20 engines (680 shp (510 kW) Pratt & Whitney Canada PT6A-27 engines optional) and more fuel, but without all of the structural reinforcements of the G-21C. 10,500 lb (4,800 kg) gross weight. One converted.[4]
G-21G
The final McKinnon conversion also was fully certified as a new model with 680 shp (510 kW) PT6A-27 engines, 586 US gal (2,220 l; 488 imp gal) of fuel, and 12,500 lb (5,700 kg) gross weight. Two converted.[10]

13 March 1947
A Grumman JRF-6B of Loftleiðir with seven passengers and a pilot crashed immediately after takeoff on Hvammsfjörður by the town of Búðardalur in Iceland. The pilot and four other passengers were rescued by a boat after they evacuated the plane. Three passengers could not evacuate the plane and went down with it under water. One of the passengers rescued did not survive. The pilot and three passengers survived; four passengers were killed.[29]
21 August 1958
N720 crashed in the Brooks Range, near the upper Ivishak River, in Alaska, killing U.S. Fish and Wildlife Agents Clarence J. Rhode and Stanley Fredericksen, and Clarence's son Jack. The crash site was not found until August 23, 1979.[30]
27 January 1961
A JRF-5 of the French Navy crashed, killing Admiral Pierre Ponchardier and five others. This accident led the French Navy to retire all of their Grumman JRF-5 Gooses in the spring of 1961.[31][32]
30 July 1971
One person was killed and one was injured when a Grumman G-21A taking off from the airport in Greenville, Maine experienced engine failure or malfunction during takeoff. The NTSB determined the probable cause to be the pilot's lack of familiarity with the plane and fuel mismanagement.[33]
22 June 1972
N1513V of Reeve Aleutian Airways was written off at False Pass, Alaska.[34][35]
2 September 1978
Charles F. Blair Jr., former Naval Air Transport Service and Pan American Airways pilot and husband to actress Maureen O'Hara, was flying a Grumman Goose that belonged to his company, Antilles Air Boats, from St. Croix to St. Thomas in the U.S. Virgin Islands when it crashed into the ocean due to failure of the left engine. Three passengers and he were killed; seven passengers were severely injured.[36]
24 July 1984
Grumman Goose G-21A, Serial # B-114, Registration: N 2021 A, Hal’s Air Service, Piloted by Hal Dierich, Four Fatalities including pilot. Collision with water in the narrow strait NW of Monashka Bay near Ouzinkie, Kodiak Island, AK. [37]
15 February 2005
A 1939 Grumman Goose G-21A, registered N-327, crashed around 9:30 am in a field on Route 14A near Penn Yan, New York after an engine failure simulation went wrong. The plane fell rapidly, with the left wing hitting the ground first, before the badly damaged plane burst into flames on impact. Pilots Paul and Daryl Middlebrook, both of Penn Yan, escaped serious injury. The plane, originally owned by the Peruvian Air Force, had starred in the 1980s ABC television series Tales of the Gold Monkey as Cutter's Goose.[38][39][40]
3 August 2008
A Grumman Goose of Pacific Coastal Airlines with seven passengers and crew crashed during a flight from Port Hardy to Chamiss Bay. The aircraft was completely destroyed by a fire. There were only two survivors.[41]
16 November 2008

JRF 6B Goose in U S Navy JRF 1 markings In 1936 a group of wealthy residents of Long Island including E Roland Harriman approached Grumman and commissioned an aircraft that they could use to fly to New York City 1 In response the Grumman Model G 21 was designed as a light amphibious transport Grumman produced a high wing monoplane of almost all metal construction the trailing half of the main wing and all of the flight control surfaces except for the flaps were fabric covered It was powered by two 450 horsepower 340 kW Pratt amp Whitney R 985 Wasp Junior nine cylinder air cooled radial engines mounted on the leading edges of the wings The deep fuselage served also as a hull and was equipped with hand cranked retractable landing gear First flight of the prototype took place on May 29 1937 2 The fuselage also proved versatile as it provided generous interior space that allowed fitting for either a transport or luxury airliner role Having an amphibious configuration also allowed the G 21 to go just about anywhere and plans were made to market it as an amphibian airliner 3 Modifications Edit McKinnon G 21G Turbo Goose conversion with 680 shp 510 kW Pratt amp Whitney Canada PT6A 27 turboprops A number of modifications were made for the Goose but the most numerous are those by McKinnon Enterprises of Sandy Oregon which holds 21 supplemental type certificates STCs for modifying G 21 series aircraft and which also manufactured four different conversions that were recertified under a separate FAA type certificate as brand new McKinnon airplanes 4 The first was the McKinnon model G 21C which involved replacing the original R 985 radial engines with four Lycoming GSO 480 B2D6 piston engines It was approved under TC 4A24 on November 7 1958 and two examples were converted in 1958 1959 New production Edit In November 2007 Antilles Seaplanes of Gibsonville North Carolina announced it was restarting production of the turbine powered McKinnon G 21G Turbo Goose variant now identified as the Antilles G 21G Super Goose 1 Pratt amp Whitney Canada PT6A 34 turboprops flat rated to 680 shp 510 kW would have replaced the original PT6A 27 engines 1 and the airframe systems and especially the avionics aviation electronics i e radios and navigation systems would have been updated with state of the art glass panel instrumentation and cockpit displays However as of 2009 Antilles Seaplanes manufacturing center has been foreclosed and sold at auction The fate of new Goose production is currently unknown 5 Operational history Edit Royal Air Force Goose Alaska Island Air G 21A 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 In addition to being marketed to small air carriers the G 21 was also promoted as a military transport In 1938 the U S Army Air Corps 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 amphibious aircraft was also adopted by the Coast Guard and during World War II served with the Royal Canadian Air Force in the transport reconnaissance rescue and training roles The G 21 was used for air sea rescue duties by the Fleet Air Arm who assigned the name Goose A single aircraft was used briefly by No 1 Air Ambulance Unit Royal Australian Air Force in the Mediterranean 21 After the war the Goose found continued commercial use in locations from Alaska to Catalina and the Caribbean A total of 345 were built with about 30 known to still be airworthy today when although around 60 are still on various civil registries many of them are known to have crashed or been otherwise destroyed most being in private ownership some of them operating in modified forms 6 Variants EditG 21 The original production version these were powered by two 450 hp 340 kW Pratt amp Whitney Wasp Junior SB engines at 7 500 lb 3 400 kg gross weight with six passengers and 12 were built all converted to G 21A standards 7 G 21A Increased gross weight 8 000 lb 3 600 kg 30 built 7 G 21B Export coastal patrol flying boat armed with 30 in 7 62 mm machine gun in bow and dorsal hatches and two 100 lb 45 kg bombs underwing 12 built for Portuguese Naval Aviation 7 G 21C Conversion by McKinnon Enterprises these were re engined with four 340 hp 250 kW Lycoming GSO 480 B2D6 air cooled geared and supercharged flat six engines and fitted with retractable wingtip floats a fiberglass radar nose a one piece wraparound windshield and enlarged cabin windows gross weight increased to 12 499 lb 5 669 kg as result of internal structural reinforcements Two were converted as piston powered models G 21C in 1958 1959 and two other airframes subsequently were converted in 1968 but with two 550 shp 410 kW Pratt amp Whitney Canada PT6A 20 turboprops per STC SA1320WE as G 21C Hybrids Two G 21C Hybrids were identical to the later 10 500 lb 4 800 kg model G 21E but they were never certified as such 8 G 21D One G 21C was further converted by McKinnon with an extended nose marked by two extra windows on each side and accommodating another four passengers Recertified as G 21D in 1960 In 1966 it was re engined with two 550 shp 410 kW PT6A 20 turboprops and fitted with revised Alvarez Calderon electric flaps in accordance with STC SA1320WE retaining the G 21D designation but subsequently identified as the McKinnon Turboprop Goose 9 G 21E A fully certified new model it was based on a simplified turbine conversion of the McKinnon G 21C with 550 shp 410 kW PT6A 20 engines 680 shp 510 kW Pratt amp Whitney Canada PT6A 27 engines optional and more fuel but without all of the structural reinforcements of the G 21C 10 500 lb 4 800 kg gross weight One converted 4 G 21G The final McKinnon conversion also was fully certified as a new model with 680 shp 510 kW PT6A 27 engines 586 US gal 2 220 l 488 imp gal of fuel and 12 500 lb 5 700 kg gross weight Two converted 10 The sole Kaman K 16B tilt wing STOL research aircraft Kaman K
