AT-402B

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.

Performance Notes:

  • AT-402B with PT6A-15AG engine has 680 SHP at 2200 RPM.
  • Sealed engine induction system locks out contaminants, extends service life and reduces maintenance.
  • Improved oil cooling system lowers temps in flight and on the ground.
  • Cruise at 160 m.p.h.; work at 140 m.p.h.
