The Grumman G-164 Ag Cat is a single-engined biplane agricultural aircraft, developed by Grumman in the 1950s.
In 1955, Grumman preliminary design engineers Joe Lippert and Arthur Koch proposed the design for a "purpose-built" crop-dusting airplane as a means of fulfilling a pressing need in the agricultural community, as well as the perceived need for Grumman to diversify its product lines. The initial market survey indicated that 100 to 200 of this type could be sold each year. Lippert's initial proposal was made under the project name "Farmair 1000".
The first G-164, which was built by Grumman (N74054), was equipped with a Continental W670 Series 6A-16 powerplant. The aircraft had its maiden flight on May 27, 1957, with Grumman test pilot Hank Kurt at the controls. [2] [3] This initial flight test consisted of three short familiarization hops with the take-off weight set at 3122 lb and the center of gravity at 31.2%. Flight tests 2 and 3, with test pilot Victor Eble, were accomplished on May 28, 1958, to evaluate its general flight characteristics. In total, 46 test flights were completed by the end of August 1958 with a general finding that this was a well-behaved aircraft with only minor refinements needed before production.
When the decision was made to authorize production, Leroy Grumman suggested marketing the aircraft under the name "The Grasshopper"; however, Dick Reade suggested "Ag Cat" following Grumman's naming tradition using the suffix "cat" in aircraft names (e.g., F4F Wildcat and F6F Hellcat). Mr. Grumman agreed and the Grumman G-164 became the "Ag Cat". [3]
Large military orders prevented the production of the Ag Cat at Grumman's Bethpage facility. Grumman's board of directors chose to subcontract the entire program to the Schweizer Aircraft Corporation of Elmira, New York. Initial production was through a contract between Schweizer [4] and Grumman. The first Schweizer-built Ag Cat, bearing registration number N10200, flew on October 17, 1958, under the control of Schweizer test pilot Clyde Cook. [3] Full production began in January 1959, with Schweizer delivering 12 FAA-certified airplanes to Grumman by March 1959. The FAA granted type certification on January 20, 1959. [5]
The ownership of the Ag Cat design has changed hands several times. Grumman transferred ownership to its commercial aircraft subsidiary, Grumman American, in 1973. A market feasibility study for a new agricultural aircraft (Ag Cat X) was completed by Grumman American in 1976. This study indicated that potential market demand existed for more than 100 aircraft each year. The study also showed that most of the concerns expressed by agricultural aircraft operators were addressed by the Ag Cat C model. The Grumman American subsidiary, which also owned the Grumman Gulfstream design series, was sold to American Jet Industries in 1978.
From initial production through 1981, Schweizer built 2,455 aircraft under contract. [6] In 1981 Schweizer bought the rights to the design and continued production under the name Schweizer Ag Cat. [4] Schweizer sold the design to Ag Cat Corp. of Malden, Missouri in 1995.
Five model G-164B aircraft were produced and registered before Ag Cat Corp. entered bankruptcy. One additional aircraft, a G-164BT500, is listed in the FAA registry as having been produced by Ag-Cat Corp., but no tail number was issued. [7] This may have been an upgrade to an existing airframe.
In February 2001, the design was sold to Allied Ag Cat Productions Inc. of Walnut Ridge, Arkansas. [5] Allied Ag Cat is not producing new aircraft, although a related company operates a large fleet of Ag-Cats.
The basic airframe incorporates many safety innovations, including a pressurized cockpit to keep pesticides out, air conditioning, and a fuselage structure that is designed to progressively collapse in the event of a collision. [4] Lippert and Koch were recognized for their innovation in agricultural aircraft, being awarded the Puffer Award by Delta Air Lines in 1974. [8]
Floats were approved for the aircraft in the early 1990s in Australia.[ citation needed ]

The Douglas DC-3 is a propeller-driven airliner manufactured by Douglas Aircraft Company, which had a lasting effect on the airline industry in the 1930s to 1940s and World War II. It was developed as a larger, improved 14-bed sleeper version of the Douglas DC-2. It is a low-wing metal monoplane with conventional landing gear, powered by two radial piston engines of 1,000–1,200 hp (750–890 kW). Although the DC-3s originally built for civil service had the Wright R-1820 Cyclone, later civilian DC-3s used the Pratt & Whitney R-1830 Twin Wasp engine. The DC-3 has a cruising speed of 207 mph (333 km/h), a capacity of 21 to 32 passengers or 6,000 lbs (2,700 kg) of cargo, and a range of 1,500 mi (2,400 km), and can operate from short runways.
The Pratt & Whitney Canada PT6 is a turboprop aircraft engine produced by Pratt & Whitney Canada. Its design was started in 1958, it first ran in February 1960, first flew on 30 May 1961, entered service in 1964, and has been continuously updated since. The PT6 consists of two basic sections: a gas generator with accessory gearbox, and a free-power turbine with reduction gearbox. In aircraft, the engine is often mounted "backwards," with the intake at the rear and the exhaust at the front, so that the turbine is directly connected to the propeller. Many variants of the PT6 have been produced, not only as turboprops but also as turboshaft engines for helicopters, land vehicles, hovercraft, and boats; as auxiliary power units; and for industrial uses. By November 2015, 51,000 had been produced, which had logged 400 million flight hours from 1963 to 2016. It is known for its reliability, with an in-flight shutdown rate of 1 per 651,126 hours in 2016. The PT6A turboprop engine covers the power range between 580 and 1,940 shp, while the PT6B/C are turboshaft variants for helicopters.

Typical of agricultural aircraft, it is a single-seat monoplane of conventional taildragger configuration. Originally powered by a radial piston engine, most examples produced since the 1980s have been turboprop-powered.
