Air Tractor AT-802

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. In the U.S., it is considered a Type III SEAT, or Single Engine Air Tanker.[3]

Development

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)[4] standard fuselage-mounted retardant tank, the Fire Boss can have optional 35 US gallons (130 L) foam tanks in the floats.[5] Operations with floats installed have been shown to produce a shorter and narrower retardant drop pattern than wheeled AT-802s.[6]

Armed version

In response to the United States Air Force's LAAR program and the growing requirement for light counter-insurgency aircraft,[7] 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,[8] and the AT-802U was displayed in 2009 at the Paris Air Show.[9]

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.

Ten AT-802i were converted by IOMAX USA into an armed configuration with Roketsan Cirit 2.75" rockets and guided bombs [10] for the UAE Air Force. The UAE operated them until November 2015[10] when they were replaced by the first three of 24 Archangels on order from Iomax.[11] The Archangel is based on a similar cropduster airframe, that of the Thrush Model 660,[12] however to create the Archangel the basic Model 660 undergoes a much more extensive rebuild in the course of its militarization. Six of the UAE AT-802i were transferred to the Jordanian Air Force.[13] with a further three being transferred to the Yemeni Government Forces where they have been used in the 2015 Yemeni Civil War.[10] Reports place Emirati aircraft in Libya flown by contract pilots.[14]

In January 2017, the US State Department approved a deal for twelve AT-802 aircraft for the Kenya Defence Forces,[15] although as of June 2017 a contract for the proposed sale had not been signed.[16]
