The Grumman G-164 Ag Cat is a single-engine biplane agricultural aircraft, developed by Grumman in the 1950s. ==Development== The Ag Cat was the first aircraft specifically designed by a major aircraft company for agricultural aviation. 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 first G-164, which was built by Grumman, accomplished its maiden flight on May 27, 1957 with Grumman test pilot Hank Kurt at the controls.〔〔Schweizer, William: ''The Ageless Ag-Cat: The Forty-year History of the Ag-Cat Agricultural Airplane'', Rivilo Books, 1995 ISBN 0-9630731-1-7〕 At this time, the Grumman G-164 did not have a name. Leroy Grumman suggested "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." 〔 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 Company of Elmira, New York. Initial production was through a contract between Schweizer Aircraft Corporation,〔Montgomery, MR & Gerald Foster: ''A Field Guide to Airplanes - Second Edition'', page 14. Houghton Mifflin Publishing, 1992. ISBN 0-7232-3697-6〕 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.〔 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. The ownership of the Ag-Cat design has changed hands several times. Grumman transferred ownership to its commercial aircraft subsidiary, Grumman American, in 1973. 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.〔Taylor John WR: ''Jane's Pocket Book Light Aircraft - Second Edition'', page 215. Jane's Publishing Company, 1982. ISBN 0-7106-0195-6〕 In 1981 Schweizer bought the rights to the design and continued production under the name Schweizer Ag-Cat.〔 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., however no tail number was issued.〔(【引用サイトリンク】title=FAA Registry - Aircraft - Make / Model Inquiry )〕 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.〔 Allied Ag-Cat are 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.〔 Lippert and Koch were recognized for their innovation in agricultural aircraft, being awarded the Puffer Award by Delta Air Lines in 1974. 〔(【引用サイトリンク】title=National Agricultural Aviation Association )〕 Floats were approved for the aircraft in the early 1990s in Australia. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Grumman Ag Cat」の詳細全文を読む スポンサード リンク
