Premier Single Engine Air Tanker 800 Gallons Hopper Capacity Pratt & Whitney PT6A Turboprop Power

Air Tractor AT-802 & Ag Special Mission Series

The Air Tractor AT-802 family is the largest single engine aircraft in production, dominating aerial firefighting, agricultural dispersal, and specialized tactical overwatch. Built around a robust welded steel tube truss frame and powered by the legendary Pratt & Whitney Canada PT6A turboprop engine, the aircraft can drop 800 US gallons of water or fire retardant in seconds or operate as an amphibious scooper in the AT-802F Fire Boss configuration.
