Role Agricultural / Fire-fighting aircraft
Manufacturer Air Tractor
First flight 1990

The Air Tractor AT-802 is an agricultural aircraft that may also be adapted into fire-fighting or armed versions. It 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.[1]

Development[edit]

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 aerial firefighting 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 820 US gallons (3,100 L)[2] standard fuselage-mounted retardant tank, the Fire Boss can have optional 70 US gallons (260 L) tanks in the floats.[3] Operations with floats installed have been shown to produce a shorter and narrower retardant drop pattern than wheeled AT-802s.[4]

Armed version[edit]

AT-802U prototype at Paris Air Show

In response to the United States Air Force's LAAR program and the growing requirement for light counter-insurgency aircraft,[5] 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,[6] and the AT-802U was displayed in 2009 at the Paris Air Show.[7]

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[edit]

  • 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[8]
  • AT-802F or AT-802AF - An aerial firefighting model 802 equipped with the Air Tractor Computerized Firegate[9]
  • Fire Boss - A model 802 equipped with Wipaire amphibious floats and Air Tractor Computerized Firegate[9]
