AIR TRACTOR AT SERIES

Air Tractor AT Series for Sale — Buy or Sell Agricultural and Firefighting Aircraft

The Air Tractor AT Series is America's premier line of agricultural aircraft — purpose-built machines designed from the ground up for aerial application, wildfire suppression, and specialized utility operations. Manufactured by Air Tractor Inc. of Olney, Texas, the Air Tractor family has set the standard for agricultural aviation since the company's founding in 1972, producing rugged, powerful, and highly efficient single-engine turboprop and piston aircraft that are operated by agricultural aviation professionals across the United States and in over 30 countries worldwide. On Airplane Trade, buyers and sellers of Air Tractor AT Series aircraft connect through a marketplace that understands the specialized demands of agricultural and firefighting aviation.

Company Background: Air Tractor Inc.

Air Tractor Inc. was founded by Leland Snow, one of the pioneer figures in American agricultural aviation. Snow had previously designed the Snow S-2 series — the aircraft that became the Grumman Ag Cat — before founding Air Tractor to produce his own, more refined designs. Air Tractor's engineering approach has consistently prioritized hopper capacity, structural durability, pilot visibility, and powerplant reliability over all other considerations. The result is a line of aircraft that has proven extraordinarily durable in the demanding world of low-level agricultural flying, where aircraft routinely make hundreds of applications per season in hot, dusty, and chemically demanding environments.

Agricultural and Firefighting Applications

Air Tractor aircraft serve a remarkably broad range of agricultural and firefighting applications:

• Crop dusting and liquid application — Herbicide, pesticide, and fungicide application over grain crops, cotton, soybeans, rice, and specialty crops
• Seeding operations — Aerial seeding of rice, grass, and cover crops; forest reseeding after fire events
• Fertilizer application — Dry and liquid fertilizer application at high volume
• Wildfire suppression (SEAT) — AT-802s certified as Single Engine Air Tankers for initial attack firefighting; used extensively by US Forest Service and state agencies
• Mosquito and pest control — Large-area application for public health mosquito abatement programs

Buying an Air Tractor AT Series: Evaluation Checklist

• Hopper and spray system condition — Chemical exposure degrades seals, fittings, and hopper linings; thorough inspection by an agricultural aviation specialist is essential
• PT6A engine logs — Verify time since hot section inspection, TBO status, and all applicable AD compliance
• Airframe corrosion — Chemical exposure in agricultural operations accelerates corrosion; inspect all steel and aluminum structure thoroughly
• Windshield and cockpit sealing — Verify integrity of cockpit seals against chemical ingestion
• GPS and flow control systems — Modern Air Tractors are equipped with sophisticated application control systems; verify functionality and calibration
