The Goodyear Duck is an American three-seat pusher-propeller amphibious aircraft developed by tire manufacturer Goodyear's aircraft manufacturing subsidiary, Goodyear Aircraft Corporation.
The Duck's development began during World War II, and the two-seat prototype known as the GA-1 first flew in September 1944. The tests were successful, and the design was first upgraded into the GA-2 with a more powerful engine and a third seat, and then into the GA-2B with an even more powerful engine. 16 GA-2s were built, but the type had no commercial potential as few private pilots could afford it. In 1950 a four-seat version version known as the GA-22 Drake was built, and finally in 1953 the GA-22A with an even more powerful 225 hp engine was built. Only one example of each was built.
One of the Duck's designers, David Thurston, went on to design several similar amphibious aircraft, like the successful Lake Buccaneer.
Goodyear kept the Ducks, and used them for tests, demonstrations and business flights.
- GA-1 Duck - Two-seat prototype originally powered by a 107 hp (80 kW) Franklin 4ACG-100-H3 piston engine, later by a 125 hp (93 kW) Franklin 6A engine, one built.
- GA-2 Duck - Three-seat version with a 145 hp (108 kW) Franklin 6A4-145-A3 engine, 16 built.
- GA-2B Duck - 165 hp (123 kW) Franklin 6A4-163-B3 engine, six converted from GA-2s in 1949.
- GA-22 Drake - Improved version with four seats. First flown in 1950, one built.
- GA-22A Drake - 225 hp (167 kW) Continental E-225-8 engine. First flown in 1953, one built.
Survivng example Edit
- Only one example of the type, GA-22A Drake N5516M survives. It is on display at the Military Aviation Preservation Society (MAPS) Air Museum in Canton, Ohio. Goodyear originally donated it to the EAA AirVenture Museum in Oshkosh, Wisconsin in 1966.
