680 SHP @ 2200 RPM

With the AT-402B, Air Tractor’s goal was to combine turbine power with affordability.  We achieved it; first by designing a compact, structurally efficient airframe and then specifying an exceptionally quiet, powerful and reliable PT6A turbine engine for faster climb rates and increased cruise speed. We designed a long, high-aspect ratio wing with Hoerner wing tips to increase wing efficiency, reduce drag and to lower stick and rudder forces so the controls are light and responsive, greatly reducing pilot fatigue.
The end result is an ag plane that pilots love to fly, even at the end of a long day. When your operation is ready to transition to turbine power, it’s time to investigate the AT-402B.
