Amphibious AT-802F Scooping Single Engine Air Tanker

2025 Fire Boss Block Changes

Stock Configuration Changes​

1. Single Piece Nose Fork

Reduce maintenance hours and better landing performance.

2. Hydraulic Pump Relocation

This change moves the CG of the aircraft forward and reduces weight, making it easier to keep aircraft inside the weight & balance envelope for multiple loading configurations.

3. Access Cover Seals

Now replaceable, you will no longer need to use sealant.

4. Float Floor Changes

You asked for it and we delivered! 19 pounds of weight reduction. Panel changes and attachment points provides easier access to the bulk head and scoop area.

5. Scoop Lockout for Fire Gate Arming

Designed for use with the Trotter Gen III gate, this ensures that the scoop cannot be deployed unless the gate is armed.

6. Change Ballast from Lead​ to Steel

Better for the environment and better for you. Switching to steel ballast in the 2-Seat Fire Boss removes manufacturing and handling constraints associated with lead.

7. High Altitude Scooping Data in AFM

We increased the scooping elevation from 8,000ft to 10,000ft. Opening up more capability for operation.
