Narrative:
At the beginning of an aerial application run, the pilot rotated the airplane near the end of the runway; the airplane lifted up from the ground, yawed, and then shuddered. The airplane descended, the left wing contacted the ground, and the airplane slid to a stop. The circumstances of the accident are consistent with an aerodynamic stall during takeoff because the pilot failed to obtain adequate speed to climb the airplane.

Probable Cause: The pilot's failure to obtain adequate airspeed during the takeoff roll, which resulted in an aerodynamic stall.
