820 USG (3,104L) water capacity plus up to 78 USG (296 L) foam capacity
2. Safe Instrumentation

The scooping control panel is located so the pilot’s attention is maintained at windscreen level during critical operation phases.

3. Pratt & Whitney 1,600 hp PT6A-67F Engine

The turbine PT6A-67F boasts legendary reliability, fast start-up with no warm-up period, 150 knots cruise speed, and exceptional performance with the ability to quickly climb to high mountain elevations and execute aggressive down-slope drops.

4. The Airframe

A rugged aircraft built with confined area operations and maneuverability in mind. The AT-802F has been purpose built and FAA-certificated for aerial firefighting. It can be refitted with conventional landing gear in the off season to perform additional missions.

Single-Seat & Two-Seat Trainer Models Available


The fire gate controls the rate and volume of water release. It allows the pilot to perform accurate salvo or string drops.

Fire gate options include:

  • Air Tractor Gen II FRDS (Factory Standard)
  • Hydramax Fire Gate
  • Hatfield Fire Gate

Wipline 10000 Amphibious Floats

6. Retractable Landing Gear

Water Delivery Based on Distance From WAter Source

Distance between fire and water source (in US Miles) Average turnaround time (in Minutes) Water delivered to fire per hour (in US Gallons)
1 3 14,000
5 4 10,500
10 6 7,000
15 9 4,666
20 11 3,818
This chart shows the gallons of water the Fire Boss is able to deliver to a fire based on the distance between the fire and the nearest scoopable water source. It assumes that the Fire Boss has 2.5 hours of fuel endurance including a 30-minute reserve (U.S. Fire Agency Minimum Requirement). It also assumes scooping loads begin at approximately 600 gallons and approach 820 gallons as fuel burns and that no foam is carried onboard.
