About the Air Tractor AT-402
The Air Tractor AT-302 was introduced as a turboprop conversion of the earlier AT-301, powered by a 600 shp Lycoming LTP101 engine. The AT-400, certified in April 1980, replaced the radial engine with a 680 shp Pratt & Whitney Canada PT6A-15AG turboprop and expanded the hopper to 400 US gal. With an empty weight of 4,135 lb and a max takeoff weight of 7,860 lb, its useful load is about 3,725 lb. Its service ceiling is approximately 13,100 ft, and it retains the low-wing taildragger layout for agricultural spraying. The AT-402, first flown in 1986, is a further development of the AT-400, using the same PT6A-15 engine but with lengthened wingtips and refinements in aerodynamics. It shares the AT-400’s empty and maximum weights (4,135 lb empty, 7,860 lb MTOW) and thus the same useful load of roughly 3,725 lb. Its service ceiling is also around 13,100 ft, and it carries a 400 US gal hopper.
