The pilot of the turbine-powered airplane reported that, during takeoff for an agricultural application flight, he failed to move the power lever from the ground idle position to the flight position. During takeoff, the airplane did not attain sufficient airspeed, aerodynamically stalled about 50 ft above the ground, impacted terrain, and came to rest inverted.

The airplane sustained substantial damage to the fuselage, both wings, and the empennage.
