Air Tractor

From Wikipedia, the free encyclopedia

The Air Tractor is a series of agricultural aircraft, used for crop dusting. Leland Snow established Air Tractor Inc. in order to manufacture a new agricultural aircraft derived from the S-2B aircraft (designed by his previous company Snow Aeronautical Company). Designated Model AT-301 Air Tractor, the aircraft first flew in 1973. Other variants include the turboprop AT-502, and the 2-seat AT-503A. Over 1700 have been built.

The Aircraft can accommodate a pilot, and a chemical hopper. In later variants, a passenger or observer can also be carried.
