The Air Tractor AT-500 is a family of agricultural aircraft that first flew in
the United States on 25 April 1986, manufactured by Air Tractor Inc. Of
monoplane low-wing, tail dragger configuration, they carry a chemical hopper
between the engine firewall and the cockpit. Compared with their predecessor,
the AT-500 family mostly feature a wingspan increased to 50 ft (15.2 m), and an
additional fuselage stretch of 22 in (56 cm), allowing for a larger chemical
hopper. Almost all variants have a second seat for a passenger or observer.
