CHAPTER 1 - GENERAL

1.1 AIRPLANE

The airframe of the Fire Boss is adapted from the Air Tractor AT-802A agricultural airplane. It is an all-metal, low 

cantilever wing design. It is powered by a Pratt and Whitney PT6A-67AG turboprop engine of 1350 SHP or PT6A-

67F of 1600 SHP. The airframe is detailed in Air Tractor publications.

To create this fire suppression version of the airplane, a number of changes to the landplane were incorporated:

1.  Amphibious floats with hydraulically actuated water scoops are installed.

2.  The Air Tractor Fire Retardant Delivery System (FRDS) is utilized.

3.  The Air Tractor foam system and controls are utilized.

4.  Additional foam tanks in the floats supplement the standard firewall tank.

5.  Changes to the hopper venting system are incorporated.

6.  A new upper instrument panel is added to contain some of the scoop related and system controls and  

   

     indicators.

7.  A bilge pumping system and a water in floats warning system are incorporated.

These changes will be briefly discussed in the following paragraphs.

1.2 FLOATS

The model 10000 amphibious float is an all aluminum constructed float with (12) watertight compartments of 

approximately 10,000 pounds buoyancy. As a part of the float installation, the following additional changes are 

made to the landplane:

1.  The hydraulic landing gear retraction system components and cockpit controls are added.

2.  The cockpit landing gear controls and emergency hand pump and system are added.

3.  The float water rudder retraction system and cockpit controls are added. The water rudders are locked center       

     when retracted for improved directional stability.

4.  A ventral fin is added for improved directional stability.

5.  Two auxiliary finlets are added to each side of the horizontal stabilizer for improved directional stability. Four       

      total per aircraft.

6.  The vertical fin is sealed to the fuselage/stabilizer top for improved directional stability.

7.  The open fuselage structure near the landplane tail-wheel mount is faired over for improved directional stability.
