The Air Tractor AT-802 is an agricultural and fire-fighting aircraft that first flew in the United States in October 1990 and is manufactured by Air Tractor Inc.. The AT-802 carries a chemical hopper between the engine firewall and the cockpit and another one under the belly. In the U.S., it is considered a Type III SEAT, or Single Engine Air Tanker. As of 2007, it is the largest agricultural-type aircraft to enter production.

In its standard configuration, the aircraft utilizes conventional landing gear (two main wheels and a tail wheel). However, a number of aircraft have been converted to the Fire Boss configuration, which utilizes Wipaire 10000 amphibious floats, so that it can land on a traditional runway or on water. The Fire Boss can scoop water from a lake or river for use on a fire. In addition to the standard fuselage-mounted retardant tank, the Fire Boss can have optional tanks (70 gallons) in the floats. Operations with floats installed have been shown to produce a shorter and narrower retardant drop pattern than wheeled AT-802s.

Armed version
In response to the U.S. Air Force's LAAR program and the growing requirement for light COIN aircraft, Air Tractor developed an armed model, the AT-802U, in 2008, with engine and cockpit armor, a bulletproof windscreen, self-sealing fuel tanks, and structural reinforcements for the carriage of 9,000 pounds (4,100 kg) of payload. A reinforced wing spar was certified for 12,000 hours of flight time, and the AT-802U was displayed in 2008 at the Paris Air Show

The AT-802 has also been used in counter-drug operations in the USSOUTHCOM AOR by the U.S. Department of State as a delivery vehicle for herbicides and defoliants over narcotics production facilities.

Variants

  • AT-802 - two seat (tandem) cockpit
  • AT-802A - single-seat cockpit
  • AT-802U - two seat(tandem) heavily armored military version, modified with sensors and reinforced for weapons carriage
  • AT-802F or AT-802AF - A firefighting model 802 equipped with the Air Tractor Computerized Firegate
  • Fire Boss - A model 802 equipped with Wipaire amphibious floats

The two “official” models are AT-802 (two seat cockpit) and AT-802A (single seat cockpit). Either of these aircraft can be used for agricultural work or for firefighting.
