Turbine Conversions’ Fire Retardant Delivery System

Turbine Conversions, Ldt/Hatfield Fire gates are fighting wildfires around the world with great success! The reliability of the Hatfield Gate has been proven in the field for more than 2 decades giving TCL the reputation as the first choice in fire gates. And is now approved by ANAC Brazil!

Our unique clam shell design which reduces pitch up after the drop makes the Hatfield Gate stand out as an industry leader.

We are the only US company that builds a Fire Gate for all models of Air Tractor. Our STC covers 38″, 41″ and AT gate box sizes, this versatility allows the Hatfield Gate to convert most Ag aircraft into Fire Bombers including Air Tractor 502, 602, 802 &  M-18 Dromaders .

Coming soon is the approval for the 660 Thrush Fire Gate.

The Hatfield Gate has received full IAB (Interagency Air Tanker Board) approval, along with the approval of the BLM (Bureau of Land Management) and USFS (US Forest Service) to work on federal and state contracts.

TCL is the first to receive ANAC approval in Brazil for all models of Air Tractor to install hydraulic fire gate.
