The state of Georgia’s Forestry Commission has purchased two Thrush 510G Switchback single engine air tankers (SEATs).
The 510G model was introduced by Thrush in 2012 featuring a redesign of everything forward of the firewall including a different engine, the 800 shp GE H80 turbine.
The version acquired by Georgia has a dual cockpit and control systems, unusual in a SEAT, but it enables the aircraft to serve in a training role for Georgia Forestry Commission pilots.
The “Switchback” part of the name is an option which means in addition to delivering 500 gallons of water or fire retardant, it has the ability to switch from agricultural spray duties to firefighting capabilities in a matter of minutes thanks to its unique fire gate delivery system. These were the first Switchbacks delivered by Thrush, even though they have sold more than 100 510G’s.
“We’re extremely proud to be adding the Switchback to our aerial firefighting fleet,” said Georgia Forestry Commission’s director, Chuck Williams. “It boasts many advantages for our firefighting efforts and heralds an exciting new chapter in our commitment to protect and conserve the more than 24 million acres of timber land across our state. You’ll see these aircraft deployed not just for rapid fire suppression – but also in the very important role of rapid fire detection, which can sometimes make all the difference in being able to contain a wildfire, versus having it become uncontrollable.”
Specifications of the 510G:
- Working speed: 90-150
- Stall speed as usually landed: 55 mph
- Take-off distance at 10,500 pounds: 1,500 feet
- Landing Distance as Usually Landed w/Reverse: 350 feet
- Cruising speed at 55% power: 159 mph
