The Air Tractor AT-802A is an all-metal cantilever low-wing monoplane designed especially for agricultural or fire fighting
operations. It has a hopper of no less than 800 U.S. Gallons and is powered by a Pratt & Whitney PT6A turboprop engine which
is highly suited for this type of flying. The standard engine for the fire-fighting versions is the 1350 hp PT6A-67AG. A popular
engine is the 1295 hp PT6A-65AG. Other PT6A engines are optional, including the 1424 hp PT6A-67F. The propeller is a Hartzell
five-blade constant speed prop with reversing capabilities.
In 1953, Leland Snow constructed his first crop-duster Model S-1 before graduation from Texas A&M University.
The Texas A&M College Aircraft Research Center is known from the AG-1 Agricultural plane that was designed by
Fred Weick in 1950. The AG-1 might be considered as the mother of all modern crop-sprayers in the world. The prototype
Model S-1 (N5385N c/n 1001) was extensively tested in South America before the improved Model S-2 reached production.
The pre-production prototype Model S-2, was first flown in 1956. Production of the S-2B by Snow Aeronautical Company
started in 1958. North American Rockwell acquired the design and production-rights of the S-2 series in November 1965.
The S-2R was marketed by the growing Aero Commander Division of Rockwell. In 1970, Snow resigned from Rockwell and he
subsequently initiated design of a brand new low-wing crop spraying aircraft and formed Air Tractor Inc. to develop it.
In 1972, construction began on the first Air Tractor, Model AT-300, a modern ag plane that bore a close resemblance to
the Snow S-2D with its closed cockpit and fixed tailwheel undercarriage. The prototype Air Tractor AT-300 (N44200 c/n 300-001)
first flew in September 1973. The production version, the AT-301, had a 600 hp Pratt & Whitney R-1340 radial engine and a
crossweight of 6,900 lb. Air Tractor’s first turbine model, the AT-302, was introduced in 1977. Specifically for aerial
firefighting, Air Tractor designed the AT-802. The airframe was based on the 500 U.S. gallons AT-503A with a dual cockpit in
tandem configuration. Not long after the completion of the AT-802F, Snow made the decision to adapt the aircraft for
agricultural use. At that time, the standard for the ag industry were 300 and 400- U.S. gallons planes, and the AT-502
was only a few years in production. Snow swapped the tandem cockpit for a single-seat cockpit, added spray plumbing and booms,
and designated the 800 U.S. gallons ag plane: model AT-802A. In December 1992, the AT-802A receive its FAA Type Certificate.
In 1993, production of AT-802 series aircraft began with two models: the AT-802F, 2-seat single engine air tanker for aerial
firefighting, and the AT-802A, a single-seat airplane with a payload of 4.195 kg and an 800 U.S. gallons hopper for high
production agricultural spraying. On 1 July 2008, Air Tractor, Inc. became an employee-owned company. Today, Air Tractor produces
the most extensive line of ag aircraft with 400, 500, 600, 800 and 1,000- U.S. gallons capacities; powered by Pratt & Whitney
piston or turbine engines. On 6 May 2019, the 800th aircraft in the AT-802 series was delivered to a customer.
On 14 December 2016, Air Tractor AT-802A s/n 802A-0685 was registered N80166 to its manufacturer Air Tractor Inc., Olney, Texas.
19 January 2017, is given as A/W date for the N80166. On 28 February 2017, Air Tractor AT-802A N80166 was registered with Aero Spray,
Appleton, Minnesota. On 10 September 2017, the 2017-built Air Tractor AT-802A N80166 was seen in service as '210 FIRE' and fitted with
floates with 'Fire Boss' titles at the Columbia Gorge Regional Airport, also known as 'The Dalles Airport' in Klickitat County in the U.S.
state of Washington.
